Lessons From the Stagflation Era (1968–1982)
Periods of stagflation—when inflation rises while economic growth slows—tend to challenge traditional investment portfolios. Assets that perform well during periods of stable growth often struggle when inflation accelerates, interest rates rise, and financial conditions tighten.
The United States experienced such a period during the late 1960s through the early 1980s, culminating in the inflation crisis that forced Federal Reserve Chairman Paul Volcker to push the Fed Funds Rate above 19% in June 1981 in order to restore monetary stability.
Because stagflation environments are relatively rare, the 1970s provide one of the clearest historical case studies for understanding which asset classes preserve purchasing power during inflationary shocks.
To examine this question, the following analysis uses a dataset from NYU Stern, which tracks long-term returns across major asset classes including equities, government bonds, corporate bonds, real estate, gold, and Treasury bills.
By comparing the performance of these assets between 1968 and 1982, we can see how different parts of the financial system responded to rising inflation, oil shocks, and tightening monetary policy.
Asset Class Performance During the Stagflation Era (1968–1982)
Using the NYU Stern historical returns dataset, the cumulative nominal performance of major asset classes during the stagflation period was as follows:
| Asset | 1968 Value | 1982 Value | Total Change | Real Return |
|---|---|---|---|---|
| S&P | 3694 | 9105 | +146% | +8% |
| T-Bill | 207 | 574 | +177% | +22% |
| 10Y | 287 | 644 | +124% | -1% |
| Baa | 615 | 1614 | +162% | +15% |
| RE | 300 | 840 | +180% | +23% |
| Gold | 190 | 2227 | +1,070% | +1,070% |
| CPI | 100 | 227 | +127% |
While nominal returns were positive across most financial assets, inflation rose at nearly the same pace as equities, meaning real returns were significantly lower.
Gold was the clear outlier, rising more than tenfold over the period.
One notable feature of the data is the performance of short-term Treasury bills. During the 1970s, T-Bills roughly kept pace with CPI inflation because short-term interest rates rose as inflation accelerated. Since T-Bills mature quickly, their yields reset frequently and were able to adjust upward.
By contrast, long-term bonds suffered large losses as rising inflation pushed yields higher and bond prices lower.
It is important to note that this conclusion depends on CPI accurately measuring inflation. If CPI understates the true increase in the cost of living, then even T-Bills likely lost purchasing power during the period.
This dynamic helps explain why Paul Volcker eventually pushed short-term interest rates above 15% in the early 1980s to break inflation.
Note: Gold returns are not deflated by CPI. Gold historically functioned as money itself rather than merely an asset. If gold is treated as the monetary unit, CPI already reflects how fiat currency depreciates relative to goods and services, while changes in the gold price represent the re-pricing of that currency.

Note: Returns for financial assets and real estate are shown after subtracting CPI inflation. Gold is shown in nominal terms because it historically functioned as a monetary benchmark rather than a financial asset.
Key Observations
• Gold dramatically outperformed all financial assets, particularly during the inflation spikes of 1973–1974 and 1979–1980.
• Equities roughly tracked inflation over the full period, resulting in weak real returns.
• Long-duration bonds were severely impacted by inflation, producing deeply negative real returns in several years.
• Treasury bills performed relatively well, occasionally producing small positive real returns due to rising interest rates.
• Real estate produced modest nominal gains, but most of the appreciation reflected inflation.
Interest Rates and Equity Valuations
Rising inflation also had a profound effect on financial valuations. As interest rates increased, equity multiples compressed sharply. The S&P 500 price-to-earnings ratio fell from 18x in the late 1960s to roughly 7x by the early 1980s as investors demanded higher returns to compensate for inflation and rising bond yields.

What This Shows
- Nominal equity returns masked a large loss in real value.
In dollar terms the S&P 500 rose from about 104 to 141 between 1968 and 1982 (~+35%). On the surface this appears to be modest positive performance. - Measured in gold, equities collapsed.
The S&P 500 fell from roughly 3 ounces of gold to about 0.3 ounces, an ~89% decline in gold terms. - The decline occurred during the two major inflation shocks.
The sharpest drop happened between 1972–1974 and again during the 1979–1980 inflation spike, when gold repriced rapidly against fiat currency. - Financial assets struggled in an inflationary monetary regime.
Even though stocks eventually recovered somewhat in dollar terms, their value relative to hard assets deteriorated significantly during the stagflation decade. - Gold functioned as the primary repricing mechanism.
The rise in gold did not just represent commodity appreciation – it reflected a revaluation of currency and financial assets during a period of high inflation and monetary instability.
The 1970s illustrate that during periods of persistent inflation and rising interest rates, financial assets often stagnate while hard assets—especially gold—become the primary mechanism through which currency is repriced.
