Prices in an economy move for many different reasons. Which description captures the condition economists are identifying when they say an economy has inflation?

A one-off jump in the general price level that reverses within a few months once the disruption that produced it has passed through the economy.

A sustained, broad-based rise in the general level of prices for goods and services, leaving each unit of currency able to buy less than it did before.

A lasting rise in the price of one heavily traded commodity, which qualifies on its own whenever that commodity is an input to a wide range of production processes.

A rise in the market value of shares, bonds and property, which lifts the general price level because those holdings are revalued upward across the economy.

An adviser tells a client that a set of figures will be presented in real rather than nominal terms. What does stating a figure in real terms mean?

It has been stated net of the tax charged on the gain, on the view that only the amount the client keeps after tax is genuine.

It has been stated at the dollar amount actually received at the time, before any adjustment for the change in the price level is applied.

It has been adjusted for the change in the price level, so that amounts from different periods are expressed in constant purchasing power.

It has been averaged across several periods, so that one unusually strong or weak year does not distort the picture the series gives.

Over a twelve-month period housing costs rise far faster than prices generally, while healthcare costs are flat. How will the Consumer Price Index and the Personal Consumption Expenditures Price Index compare over that period, and why?

The Consumer Price Index will read the higher of the two, because housing carries a larger weight in its basket than it carries in the other measure.

The Personal Consumption Expenditures Price Index will read the higher of the two, because its chain weighting raises the weight of any category whose price is rising.

The two will read the same, because both are built from the prices of one common basket of consumer goods and services collected by the same agency.

The Consumer Price Index will read the lower of the two, because its basket is fixed between revisions and so cannot register the new housing costs at all.

The GDP deflator differs from the consumer price measures in both what it covers and what it is mainly used for. Which statement describes that difference correctly?

It covers only the goods and services bought by urban households, and it is used mainly to set the annual cost-of-living adjustments made to federal benefit programmes.

It covers every good and service counted in national output, and it is used mainly to convert nominal output figures into real ones rather than to follow consumer prices.

It covers every good and service counted in national output, and it is published weekly so that analysts can follow price pressure between the monthly consumer releases.

It covers every good and service counted in national output, but it is reported only as an index level and never as a rate of change, so no inflation rate comes from it.

In one month the prices producers receive for intermediate goods rise sharply while consumer prices are flat. What does the producer figure tell an analyst about consumer inflation?

That consumer inflation will not change, because prices received by producers are excluded from every consumer price measure and so can never reach them.

That consumer prices have already risen by a matching amount over the same month, because the two series measure the same underlying transactions recorded at different stages of processing.

That cost pressure is building earlier in the production chain and tends to reach consumer prices later, because producers' cost increases are generally passed on in time.

That the consumer measure must be wrong for that month, because an increase in production costs feeds through into retail prices immediately and in full.

An economy is at full employment, large government transfers have raised household spending and credit is cheap. Prices are rising while output and employment continue to grow. On these facts, what is the price pressure best attributed to?

An unusually fast rise in the prices of a few imported commodities, which lifts the measured rate without any broad pressure behind it at all.

Rising production costs forcing firms to raise their prices, which is the only way that prices and employment can both climb at the same time in any economy.

A fall in the economy's productive capacity, because prices can rise generally only where the ability to produce has been damaged in some way.

Spending in the economy exceeding what the economy can produce at current prices, so that buyers bid against one another for a limited supply of goods and services.

The supply disruption that began an inflationary episode has fully reversed and input prices are back where they started, yet consumer price inflation is still elevated two years later. What best explains the persistence?

Workers and firms now expect prices to keep rising and set wages and prices on that expectation, so each round of increases supplies the reason for the next.

The original disruption is still feeding through to buyers, because an increase in input costs takes several years to reach the prices charged to final consumers in every case.

Price indices are built so that a past increase keeps lifting the measured rate for years after the price concerned has stopped rising at all.

Firms are rebuilding the profit margins compressed during the disruption, which they can do only by holding their prices permanently above their costs.

The quantity theory of money, written as MV equals PQ, implies that where velocity and real output are stable an increase in the money supply must appear in the price level. How well does the long historical record support that implication?

The record matches the theory closely, because the velocity of money and real output are stable enough that money growth and the price level move together year by year.

Sustained inflation has consistently required sustained money growth, but the link is neither mechanical nor immediate, so one year's money growth does not map onto that year's price rise.

The record contradicts the theory outright, because inflation has been sustained over long periods with no accommodation at all from the money supply.

The record cannot speak to the question, because the money supply has never been measured consistently enough for any comparison with the price level.

An investor holds a fixed-rate bond with eight years remaining when inflation turns out much higher than expected and the central bank raises rates in response. In which two distinct ways is that holder worse off?

The coupons buy less than was expected, and the principal repaid at maturity is cut in nominal terms in line with the purchasing power that has been lost.

The bond's market price falls as yields rise, and the issuer's credit standing weakens automatically, because inflation raises what it costs the issuer to service the debt.

The bond's market price falls as yields rise, and the fixed coupons that continue to arrive buy less than they were expected to buy when the bond was bought.

The bond's market price rises as yields rise, and that gain is taxed as ordinary income before the investor can put the proceeds back to work at the higher rate.

Equities are often said to protect against inflation because companies can raise their selling prices. Why has the actual record been more mixed than a simple pass-through of higher prices into earnings would suggest?

Protection depends entirely on the dividend, so companies paying a rising dividend give complete protection and companies retaining their earnings give none at all.

Companies pass their higher prices through only after a lag of several years, so the protection arrives once the inflation has ended and the shares have already derated.

A share represents a claim fixed in nominal terms, so a holder's return is eroded by inflation to the same degree whatever the wider economic backdrop happens to be.

Moderate inflation alongside strong earnings growth has supported share prices, while high inflation that forces aggressive tightening lifts discount rates and slows the economy.

Demand for inflation protection surges and the real yield on Treasury Inflation-Protected Securities falls below zero. What does that movement mean for an investor buying at that point?

The protection has become more expensive: the same inflation adjustment is being bought on a yield below what a purchaser in calmer conditions would have received.

The protection has become cheaper, because heavy demand pushes the price of these securities down and the yield available to a new buyer correspondingly up.

Nothing changes for the buyer, because the yield on these securities is fixed by the Treasury at issue and does not respond to demand in the secondary market.

Nothing changes for the buyer, because the inflation adjustment rises by exactly the amount the yield has fallen and the total return is unaffected.

The Federal Reserve describes its two percent inflation goal, defined on the personal consumption expenditures measure, as symmetric. What does describing the target that way commit the committee to?

Treating two percent as a ceiling that policy must keep inflation beneath, so that any outcome below the figure is a satisfactory one.

Treating inflation that runs persistently below two percent as a shortfall of the same kind as inflation running persistently above it.

Returning inflation to exactly two percent in each calendar year, with a deviation in either direction corrected within the following twelve months.

Applying the same policy response to a price rise caused by a disruption to supply as to one caused by demand running ahead of capacity.

A central bank raises its policy rate in response to inflation, and the next two monthly inflation readings come in unchanged. What should the committee conclude from those two readings?

That the channels linking rates to prices have broken down, because a change in rates reaches spending and then prices within the same quarter.

That the increase was too small, because an increase of the right size works through to the price readings that are published in the month immediately following the decision.

That little can be concluded either way, because the channels through which rates reach prices work with lags, so the increase would not yet show in the readings.

That the increase has already done its work, because readings that have stopped climbing show the upward pressure on prices has been removed.

Higher policy rates strengthen a country's currency, which makes imported goods cheaper in domestic currency. Beyond the price of imports themselves, how does that strength bear on what domestic producers charge?

Producers face higher input costs, because a stronger currency makes the imported materials they use more expensive in the currency they pay in.

Producers raise their own prices to make up for weaker export demand, passing the volume lost in overseas markets on to buyers in the domestic market.

Producers are unaffected, because the level of the currency reaches only the prices of those goods that actually cross the border into the country.

Producers whose goods compete with imports come under pressure to hold their own prices down, because buyers can otherwise switch to the cheaper imported alternative.

Between 2021 and 2023 extraordinary fiscal and monetary stimulus met supply chains that had not recovered, tight labour markets and pent-up consumer demand. What does that combination imply about how the episode had to be diagnosed?

That excess demand and constrained supply were both at work, so an account resting on either one alone would have misread the episode and the response it called for.

That it was purely a supply problem, so the price rises would have unwound on their own once shipping, logistics and component supply returned to their normal working order.

That it was purely a demand problem, because disruptions to supply affect only which particular goods are scarce and never the overall rate at which prices rise.

That tightness in the labour market was the single driver, because wage settlements set the general price level on their own whatever else is happening in the economy.

In the early 1980s the Federal Reserve raised the federal funds rate far above the prevailing rate of inflation, and the deepest recession since the 1930s followed. What was the reasoning that accepted that cost?

That the contraction was an unforeseen accident, the policy having been expected to bring inflation down with no effect on output or employment at all.

That a short and severe contraction was worth bearing in exchange for a long period of low and stable inflation once the policy had worked.

That any contraction would be brief and mild, because an economy adjusts fully to a higher level of interest rates within a quarter or two of the change.

That the contraction would be offset by an expansion in government spending, so that the cost to output and employment would never in fact be borne.

A client may start Social Security benefits now or delay and receive a larger monthly benefit. Benefits receive an annual cost-of-living adjustment. Why does a higher expected rate of inflation strengthen the case for delaying?

The percentage adjustment is itself set higher for a claim that starts later, so a delayed benefit grows at a faster rate as well as from a higher base.

A benefit claimed early is fixed in dollar terms for life, so only a benefit whose start has been delayed receives any cost-of-living adjustment at all.

The adjustments are applied to a larger starting benefit, so each year's increase is larger in dollars and the gap between the two choices widens as they compound.

Delaying shortens the period over which inflation can erode the benefit, so less of its purchasing power is lost across the whole of the client's retirement.

A planner sets an education funding target by taking today's tuition and growing it at the general rate of inflation to the year the child will enrol. Why does a target built that way tend to fall short?

Tuition is set in nominal terms and so does not move with the price level at all, which means the figure should not have been grown in the first place.

Growing a figure at a rate of inflation always understates the result, because applying a rate to a starting amount leaves the compounding out of the calculation.

The general rate of inflation already contains education costs, so applying it to tuition counts the same increase a second time and overstates the target.

Tuition has historically risen faster than prices in general, so growing it at the general rate understates the sum that will actually be required.

What Is Inflation?

Inflation is the sustained and broad-based increase in the general price level of goods and services in an economy over time, resulting in a decline in the purchasing power of money such that each unit of currency buys fewer goods and services than it did in the previous period. It is one of the most important macroeconomic variables that investment professionals must understand, because inflation affects virtually every dimension of the investment landscape including the real returns available from different asset classes, the appropriate level of interest rates set by central banks, the valuation of equities and fixed income securities, the purchasing power of client portfolios over time, and the tax treatment of investment returns that are measured in nominal rather than real terms.

Inflation is measured by tracking changes in a representative basket of goods and services over time, comparing the current cost of that basket to its cost in a prior period to calculate the rate of price increase. Different inflation measures use different baskets and different methodologies, producing different readings that are appropriate for different analytical purposes and that may diverge meaningfully during periods when specific categories of prices are moving differently from the general price level.

The distinction between nominal and real values is the most fundamental practical implication of inflation for investment analysis. Nominal values are expressed in current dollar terms without adjustment for the change in purchasing power resulting from inflation. Real values are adjusted for inflation and express economic quantities in terms of constant purchasing power, allowing meaningful comparison across different time periods without the distortion introduced by changes in the price level. An investment that generates a nominal return of five percent when inflation is running at three percent provides a real return of only approximately two percent, meaning the investor’s actual improvement in purchasing power is much smaller than the nominal return figure suggests.

How Inflation is Measured

The United States government produces several different measures of inflation that serve different purposes and that are followed closely by different constituencies of financial market participants, policymakers, and analysts.

The Consumer Price Index, universally abbreviated as CPI and published monthly by the Bureau of Labor Statistics, is the most widely recognised and most frequently cited measure of consumer price inflation in the United States. The CPI measures changes in the prices paid by urban consumers for a fixed basket of approximately four hundred categories of consumer goods and services including food, housing, clothing, transportation, medical care, recreation, and education. The CPI is available in two primary variants: the CPI-U, which covers all urban consumers representing approximately ninety-three percent of the US population, and the CPI-W, which covers urban wage earners and clerical workers and is used as the basis for Social Security cost-of-living adjustments.

The Core CPI excludes the more volatile food and energy components from the headline CPI calculation, providing a measure of underlying inflation that is less influenced by temporary supply disruptions in commodity markets and that better reflects the persistent inflationary pressures in the broader economy. Because food and energy prices can be highly volatile due to weather events, geopolitical disruptions, and supply-demand dynamics specific to those markets, the core measure is often considered a more reliable signal of the underlying inflation trend than the headline measure.

The Personal Consumption Expenditures Price Index, universally abbreviated as PCE, is the Federal Reserve’s preferred inflation measure and the basis for its two percent inflation target. The PCE is calculated by the Bureau of Economic Analysis using a methodology that differs from the CPI in several important respects. The PCE uses a chain-weighted methodology that adjusts the composition of the basket over time to reflect actual consumer spending patterns, while the CPI uses a fixed basket updated periodically through comprehensive revisions. The PCE also uses different weights than the CPI, with a lower weight on housing costs and a higher weight on healthcare spending. These methodological differences typically cause the PCE to run approximately twenty to thirty basis points below the CPI, though the differential can vary meaningfully.

The Producer Price Index, published by the Bureau of Labor Statistics, measures price changes at the producer level for goods and services before they reach consumers, tracking the prices that domestic producers receive for their output at various stages of processing including finished goods, intermediate goods, and crude materials. The PPI is a leading indicator of future consumer price inflation because producer cost increases are typically eventually passed through to consumers, making the PPI a useful early warning signal of building inflationary pressure in the production pipeline.

The GDP deflator, discussed in the GDP article in Section G, provides the broadest measure of price changes in the economy by covering all goods and services included in GDP rather than the consumer-oriented subset covered by the CPI and PCE. The GDP deflator uses a chain-weighted methodology similar to the PCE and is used primarily by economists and policymakers to deflate nominal GDP to real GDP rather than as a practical inflation measure for investment analysis.

The Causes of Inflation

Understanding the causes of inflation is essential for assessing the likely persistence and severity of inflationary episodes and for anticipating the policy responses that inflation will prompt from central banks and governments.

Demand-pull inflation occurs when aggregate demand in the economy exceeds the productive capacity of the economy at current price levels, creating excess demand that pulls prices upward as consumers and businesses compete for a limited supply of goods and services. Demand-pull inflation typically arises during periods of very strong economic growth, expansionary fiscal policy that puts significant additional purchasing power in the hands of consumers and businesses, or very accommodative monetary policy that makes credit cheap and abundant. The COVID-19 pandemic recovery provides a textbook example of demand-pull inflation, with trillions of dollars of fiscal stimulus combined with near-zero interest rates creating enormous demand stimulus that collided with supply chains that had not yet recovered from pandemic-related disruptions, producing the highest inflation in four decades.

Cost-push inflation occurs when the cost of production increases due to rising input prices, reducing the supply of goods and services at any given price level and forcing producers to raise prices to maintain their profit margins. The most common source of cost-push inflation is rising energy prices, as energy is a fundamental input to virtually every production process and transportation activity in the economy. The oil price shocks of 1973 and 1979, when OPEC embargoes and supply disruptions caused oil prices to increase dramatically in a short period, are the classic historical examples of cost-push inflation, generating the stagflation of the 1970s in which high inflation and high unemployment coexisted simultaneously, violating the traditional Phillips Curve trade-off between the two.

Built-in or wage-price spiral inflation occurs when rising prices lead workers to demand higher wages to maintain their purchasing power, and rising wages lead producers to raise prices to cover higher labour costs, creating a self-reinforcing feedback loop that can sustain elevated inflation long after the original supply or demand shock that initiated it has dissipated. The wage-price spiral is the mechanism by which inflation expectations become entrenched, as both workers and businesses anticipate continued inflation and factor those expectations into their wage and pricing decisions, making the inflation self-fulfilling regardless of whether the underlying supply and demand conditions that originally caused it still prevail.

Monetary inflation, the increase in the money supply at a rate faster than real economic growth, is emphasised by monetarist economists in the tradition of Milton Friedman as the ultimate cause of sustained inflation. The quantity theory of money, expressed in the equation MV equals PQ where M is the money supply, V is the velocity of money, P is the price level, and Q is real output, implies that if V and Q are roughly stable, increases in M must be reflected in proportional increases in P. While the relationship between money supply growth and inflation is not as mechanical or as immediate as the simple quantity theory implies, the long historical record across many countries and many episodes of high inflation consistently shows that sustained inflation ultimately requires sustained monetary accommodation.

The Effects of Inflation on Investment Returns

Inflation affects investment returns across all asset classes in ways that are pervasive, complex, and critically important for investment portfolio construction and planning.

Fixed income securities are the most directly and adversely affected by unexpected inflation, because their contractual nominal payments of interest and principal lose purchasing power as prices rise. A bond that promises to pay fifty dollars of annual interest for the next ten years and then return one thousand dollars of principal generates a real return that depends critically on the inflation rate experienced over the holding period. If inflation averages two percent annually, the bond generates a modest positive real return above its nominal yield. If inflation averages five percent, the real return is substantially negative even if the nominal return appears acceptable. The inverse relationship between bond prices and interest rates, combined with the tendency of central banks to raise interest rates in response to inflation, means that unexpected inflation typically produces both capital losses from rising yields and reduced purchasing power of the coupon income.

Treasury Inflation-Protected Securities are the primary financial instrument specifically designed to protect fixed income investors from inflation, adjusting both the principal value and the interest payments to changes in the CPI as described in the Government Bond article. TIPS provide a contractual guarantee of a positive real return above inflation, making them the closest available approximation to a genuinely inflation-protected fixed income investment. The real yield on TIPS, which represents the return above inflation that investors receive, fluctuates with market conditions and can be negative during periods of very high demand for inflation protection.

Equities have a more complex and context-dependent relationship with inflation. In theory, equities should provide a degree of inflation protection over long horizons because companies can increase their revenues by raising prices, allowing their nominal earnings to grow with inflation and supporting equity valuations in real terms. In practice, the relationship between inflation and equity returns is more nuanced. Moderate inflation that is the byproduct of a strong economy tends to be accompanied by strong corporate earnings growth and supportive equity markets. High and unexpected inflation that requires aggressive monetary policy tightening tends to be associated with rising discount rates that reduce equity valuations and economic slowdowns that pressure corporate revenues and earnings.

Real assets including real estate, commodities, and infrastructure tend to provide better inflation protection than financial assets because their values are more directly linked to the price level. Real estate generates rental income that tends to rise with inflation, and property values typically appreciate in nominal terms at least in line with general price levels over long periods. Commodities including energy, metals, and agricultural goods are themselves components of inflation indices and tend to rise in price during inflationary episodes, particularly those driven by supply shocks in commodity markets. Infrastructure assets whose revenues are contractually linked to inflation indices through rate escalation clauses provide particularly direct inflation protection.

Cash and cash equivalents are the most directly harmed by inflation because their nominal value is fixed while the purchasing power of that fixed nominal value erodes continuously as prices rise. An investor holding cash in a savings account earning one percent when inflation is running at five percent is experiencing a real return of negative four percent, losing four percent of purchasing power each year simply through the effect of inflation on the real value of their cash holdings. This inflation tax on cash holdings is one of the most important arguments for maintaining a diversified investment portfolio rather than holding excessive cash reserves beyond those needed for near-term liquidity.

Inflation and Monetary Policy

The management of inflation is the primary responsibility of central banks in virtually every major economy, and the Federal Reserve’s conduct of monetary policy is more directly shaped by inflation developments than by any other single variable.

The Fed’s two percent PCE inflation target, as discussed in the Federal Reserve article in Section F, represents the committee’s assessment of the optimal long-run inflation rate that best serves the dual mandate of maximum employment and price stability. The two percent target is symmetric, meaning the Fed is equally concerned about persistent inflation below two percent as about persistent inflation above it, reflecting the recognition that very low inflation approaching deflation creates its own set of economic problems including the zero lower bound on nominal interest rates that limits the Fed’s ability to stimulate the economy through conventional monetary policy.

The transmission of monetary policy to inflation operates through several channels that work with different time lags and with different degrees of certainty. Higher interest rates reduce borrowing and spending by households and businesses, slowing the growth of aggregate demand and reducing inflationary pressure. Higher rates also strengthen the exchange rate, making imports cheaper and exports more expensive, which reduces inflationary pressure through the price of imported goods and through the competitive pressure on domestic producers of goods that compete with imports. The most powerful channel may be the expectations channel, through which the Fed’s credible commitment to restoring price stability influences the inflation expectations of businesses and workers, preventing the wage-price spiral that can sustain inflation long after the initial supply or demand shock has dissipated.

The Federal Reserve’s credibility as an inflation-fighting institution, established through the Volcker disinflation of the early 1980s and maintained through the subsequent period of low and stable inflation known as the Great Moderation, is one of the most valuable assets of the US monetary policy framework. Anchored inflation expectations, in which households, businesses, and financial market participants expect inflation to remain near the Fed’s two percent target over the medium term regardless of short-term inflation fluctuations, are the mechanism through which credibility translates into actual price stability, as self-fulfilling inflation expectations are one of the most powerful forces sustaining elevated inflation once it has become entrenched.

Historical Inflation Episodes and Their Investment Implications

The historical record of inflation in the United States and globally provides important lessons about the investment implications of different inflationary environments.

The Great Inflation of the 1970s, during which US consumer price inflation reached double-digit levels at its peak, was the most severe sustained inflationary episode in modern US economic history and had devastating consequences for both fixed income and equity investors. Bond holders suffered severe real losses as inflation eroded the purchasing power of their fixed nominal payments while interest rates rose dramatically to compensate for the higher inflation, producing large price losses on existing bond positions. Equity investors also suffered, as the combination of higher interest rates that increased discount rates, compressed profit margins from rising input costs, and the uncertainty of the inflationary environment reduced equity valuations dramatically.

The Volcker disinflation of the early 1980s, in which Federal Reserve Chairman Paul Volcker raised the federal funds rate to twenty percent to break the inflationary psychology that had become embedded in the economy, was painful in the short term, producing the deepest recession since the Great Depression, but enormously beneficial in the long term. The successful reduction of inflation from double digits to approximately four percent by 1983 set the stage for the subsequent three-decade period of low and stable inflation that contributed to the extraordinary equity bull market of the 1980s and 1990s.

The COVID-19 pandemic inflation surge of 2021 through 2023 represented the most significant inflation challenge since the 1970s, with US CPI reaching a forty-year high of nine point one percent in June 2022. The surge was driven by the collision of extraordinary fiscal and monetary stimulus with pandemic-related supply chain disruptions, labour market tightness, and pent-up consumer demand. The Federal Reserve’s aggressive tightening cycle beginning in March 2022 produced the fastest pace of interest rate increases in four decades, generating significant losses in bond portfolios and equity market volatility while gradually bringing inflation back toward the two percent target.

Inflation in Financial Planning

For financial planners and investment advisers working with individual clients, inflation is a pervasive and critically important consideration in virtually every dimension of long-term financial planning.

Retirement planning must account for the cumulative effect of inflation on the purchasing power of retirement income over what may be a thirty-year or longer retirement horizon. A retiree who needs fifty thousand dollars per year in today’s purchasing power will need approximately ninety thousand dollars per year in twenty years if inflation averages three percent annually, requiring a portfolio large enough and invested aggressively enough to generate this growing income stream without depleting the principal. The failure to adequately account for inflation in retirement planning is one of the most common and most consequential errors in personal financial planning, as clients who appear to have adequate retirement savings based on nominal projections may be severely underfunded in real purchasing power terms.

Social Security benefits are indexed to inflation through annual cost-of-living adjustments based on the CPI-W, providing retirees with a built-in inflation hedge for this component of their retirement income. The inflation protection of Social Security benefits makes delaying the start of benefits, which increases the monthly benefit amount, particularly valuable in inflationary environments where the higher starting benefit compounds at a higher rate through cost-of-living adjustments.

Long-term financial goals including education funding, estate planning, and charitable giving must be stated and planned in real rather than nominal terms to ensure that the purchasing power of the goal is maintained over the time horizon of the plan. An education savings plan that targets a nominal amount based on current tuition costs without adjusting for the historically above-average inflation rate of higher education costs will consistently undershoot the actual cost of education at the target date.

The inflation-adjusted or real return is the appropriate measure of investment performance for long-term financial planning purposes, because the goal of investing is to maintain or grow the real purchasing power of capital over time, not merely to accumulate nominal dollars. Presenting investment returns to clients in real rather than nominal terms provides a more accurate and more meaningful picture of the progress being made toward purchasing-power-adjusted financial goals.

Examination Relevance and Key Takeaways

Inflation is tested extensively on the Series 65 examination in the context of macroeconomic analysis, monetary policy, the impact of inflation on different asset classes, investment planning for inflation, and the measurement of real versus nominal investment returns. Candidates must understand the definition and measurement of inflation including the CPI, PCE, core measures, and PPI, the major causes of inflation including demand-pull, cost-push, built-in wage-price spiral, and monetary factors, the effects of inflation on fixed income securities, equities, real assets, and cash, the Fed’s two percent PCE inflation target and the monetary policy tools used to manage inflation, and the implications of inflation for retirement planning and long-term financial goal setting.

The core points to retain are these: inflation is the sustained increase in the general price level resulting in declining purchasing power of money; the CPI and PCE are the primary US inflation measures with the PCE being the Fed’s preferred measure and the basis for its two percent target; core inflation excluding food and energy provides a less volatile measure of underlying inflationary pressure; demand-pull inflation results from excess aggregate demand while cost-push inflation results from rising input costs and built-in inflation results from wage-price spiral dynamics; fixed income securities are most directly harmed by unexpected inflation as rising yields produce capital losses and fixed nominal payments lose purchasing power; TIPS provide explicit inflation protection through principal and interest adjustments tied to the CPI; equities provide partial inflation protection over long horizons but are harmed by aggressive monetary tightening prompted by high inflation; real assets including real estate, commodities, and infrastructure provide better inflation protection than financial assets; cash and cash equivalents are the most directly harmed by inflation through the continuous erosion of purchasing power; the Fed manages inflation through interest rate policy and forward guidance with the goal of anchoring inflation expectations near the two percent target; and retirement planning must account for the cumulative effect of inflation on purchasing power over decades of retirement using real rather than nominal return assumptions.
