The most critical insight from the Great Inflation (1965-1982) is that the erosion of a central bank’s credibility creates a self-fulfilling cycle of rising prices that cannot be broken by moderate policy adjustments. While popular history often attributes the era’s economic malaise to the 1973 and 1979 oil shocks, the structural foundation for the crisis was laid much earlier through a fundamental misinterpretation of the Phillips Curve and the abandonment of a stable nominal anchor. Between 1965 and 1980, the United States saw inflation climb from a manageable 1.6 percent to a staggering peak of 14.8 percent in March 1980, a trajectory that fundamentally altered the risk profile of global capital markets for a generation.
The period was defined by a stop-go monetary policy mechanism. Under Federal Reserve Chairs William McChesney Martin and Arthur Burns, the central bank frequently tightened policy to combat rising prices, only to reverse course prematurely when unemployment began to rise. This lack of resolve created a ratchet effect: each cycle of easing began at a higher baseline of inflation than the previous one. For instance, the recession of 1969-1970 failed to reset price expectations because the Fed prioritized the executive branch’s focus on full employment over long-term stability. By the time the 1973 oil embargo hit, the Consumer Price Index (CPI) was already accelerating at 6.2 percent, leaving the economy vulnerable to a supply-side shock that pushed inflation into double digits by 1974.
The abandonment of the Bretton Woods system in August 1971 served as the primary catalyst for the decoupling of the dollar from tangible constraints. Without the gold window, the Federal Reserve operated in a purely discretionary regime. Analytical evidence suggests that the Fed’s failure during this era was not a lack of tools, but a lack of a coherent framework for managing the money supply. The real federal funds rate was frequently negative during the 1970s, meaning monetary policy was effectively stimulative even as inflation eroded the purchasing power of the dollar. For investors, the consequences were devastating. From 1966 to 1982, the S&P 500 provided a nominal return of roughly 6 percent annually, but when adjusted for inflation, the real return was effectively zero. Bonds, traditionally a safe haven, were derided as certificates of confiscation as yields failed to keep pace with the 13.5 percent inflation rate seen in 1980.
The resolution of the Great Inflation required a radical shift in the monetary mechanism. Upon his appointment in 1979, Paul Volcker shifted the Fed’s focus from targeting interest rates to targeting the growth of the money supply. This policy shift allowed the federal funds rate to reach an unprecedented peak of 20 percent in June 1981. The resulting Volcker Shock induced a severe double-dip recession, with unemployment reaching 10.8 percent in late 1982, the highest since the Great Depression. However, this aggressive stance successfully re-anchored inflation expectations, bringing CPI down to 3.2 percent by 1983.
For modern portfolio managers, the Great Inflation offers a sobering lesson in the speed at which institutional credibility can vanish. The transition from the Great Moderation of the early 1960s to the chaos of the 1970s occurred because policymakers treated inflation as a secondary concern to short-term growth. The historical precedent suggests that once inflation expectations become embedded in wage-setting behavior and corporate pricing power, the cost of correction is not a soft landing, but a significant contraction in real economic activity. Investors must distinguish between transitory supply shocks and the structural debasement of the monetary anchor, as the latter necessitates a defensive posture in long-duration assets and a pivot toward commodities or inflation-protected instruments.
