I’ve spent more time than I care to admit digging through old economic data from the 1970s. Not because I enjoy dusty library archives, but because that decade keeps whispering uncomfortable truths to anyone willing to listen. The stagflation of the 1970s—when inflation ran hot and growth froze solid—is often cited as a cautionary tale, but most investors treat it like a ghost story told around a campfire. They nod, shiver, and move on. I think that’s a mistake. The lessons are too specific, too actionable, to ignore.
Let me walk you through five things I’ve learned from that period, things that have quietly reshaped how I think about building a portfolio today. This isn’t about predicting the next crisis. It’s about preparing for the possibility that inflation and stagnation might show up together again, uninvited, and stay longer than anyone expects.
I remember reading old commodity price charts late one night and noticing something strange. During the 1970s, the biggest winners weren’t stocks or bonds. They were things you could touch. Gold went from $35 an ounce to nearly $850 by 1980. Silver, oil, grains, copper—everything physical shot higher. But here’s the part most people miss: it wasn’t just about buying gold bars and waiting. The real edge came from owning assets that had a built-in relationship with inflation, assets whose prices reset automatically as the cost of living climbed.
Consider timberland. In the 1970s, timber prices tracked inflation almost perfectly because wood is tied to construction, and construction costs rise with wages and materials. Farmland did something similar. I’m not suggesting everyone rush out and buy a forest, but the principle is worth holding: in a stagflationary environment, you want assets whose value is not determined by a quarterly earnings report but by real-world demand and replacement cost. Commodity futures, royalty trusts, and even infrastructure stocks with inflation-linked revenue—these are modern proxies for that same idea.
The counterintuitive part is that you don’t need to time the peak. The 1970s had two big inflation spikes, one in 1974 and another in 1979. Investors who bought commodities in 1972 doubled their money before the first spike even began. The trick was holding through the noisy, sideways years in between. Patience, not prediction, was the real skill.
Pricing power sounds like a buzzword, but during the 1970s it was the dividing line between survival and collapse. Companies that could raise prices without losing customers kept their margins intact. Those that couldn’t, died. I’ve looked at the list of firms that made it through that decade on decent footing, and they share a pattern: they sold things people could not postpone buying.
Think about utilities. Regulated utilities in the 1970s had automatic rate adjustments tied to fuel costs. They passed inflation straight through to customers. That’s the ideal. Oil companies, too. When crude prices quadrupled in 1973, Exxon’s earnings rose in lockstep because they owned the barrels, the refineries, and the distribution. They didn’t have to beg customers to pay more; the market did it for them.
Then there’s the less obvious group: companies with strong brands and recurring revenue. Consumer staples like household cleaners, cigarettes, and basic foods held up remarkably well. People grumbled about higher prices but kept buying. The key metric I now watch is gross margin stability. If a company can keep its gross margin above 40% through a decade of 10% annual inflation, it has real pricing power. If margins shrink during the first inflationary crackle, the stock will likely get crushed.
One fact most investors miss: during the 1974 recession, which was brutal, the top-performing S&P 500 sector was healthcare. Hospitals and pharmaceuticals had pricing power because insurance and government programs paid the bills, and demand was inelastic. That same pattern repeated in 2022 when healthcare was one of the few sectors to hold up during the Fed’s tightening cycle.
Debt is usually the enemy during inflation, but not all debt is created equal. During the 1970s, the U.S. Treasury issued something called Treasury Inflation-Protected Securities only later—they came in 1997—but the concept existed earlier in other forms. In the United Kingdom, index-linked gilts were introduced in 1981. In Brazil and Israel, inflation-indexed bonds became critical tools for savers during their own high-inflation eras.
The lesson here is that you want to own debt that adjusts with inflation, not against it. I keep a portion of my fixed-income allocation in TIPS and similar instruments, but I also look for corporate bonds that have floating-rate coupons. Banks often issue notes tied to SOFR or CPI. These aren’t exciting, but they serve a purpose: when inflation accelerates, your bond payments rise, protecting your purchasing power. In the 1970s, ordinary bonds were a trap. Investors who bought 30-year Treasuries in 1970 saw their real returns turn deeply negative as inflation ate their principal. By 1980, those same bonds had lost more than half their value in real terms.
The lesser-known angle is that during stagflation, short-duration debt can actually work. Cash equivalents, like Treasury bills, rolled over at increasingly higher rates as the Fed kept raising. Someone who simply bought 90-day T-bills and reinvested them every quarter earned more than 10% by 1979, slightly above inflation. Not great by historical standards, but far better than being locked into a 6% bond while prices rose at 12%.
Stagflation forces patience of a kind most modern investors haven’t practiced. From 1966 to 1982, the Dow Jones Industrial Average hovered between roughly 600 and 1000. No net gain in sixteen years. That’s a lateral market of brutal length. Investors who lived through it often gave up on stocks entirely, convinced equities were a dying asset class.
But during those same years, individual stocks within the index could rise 200% or fall 80%. The market wasn’t stationary; it was chaotic. The ones who did well were those who could sit through 1974’s 48% drawdown in the S&P 500 without selling, and then sit through the double dip in 1981 without losing faith. Those who sold near the bottom missed the greatest bull market in history, which began in August 1982.
I’ll be blunt: most people cannot do this. They need to feel like they are winning every quarter. So the practical solution is to build a portfolio that survives the waiting period. High dividends helped in the 1970s. The S&P 500’s dividend yield averaged over 4% during that decade, and in some years touched 6%. Reinvesting those dividends into a flat market was like accumulating shares at discount prices. When the market finally broke out, those shares appreciated hugely. In fact, an investor who reinvested dividends from 1970 to 1980 saw their total return roughly double that of an investor who simply collected the income and spent it.
That’s the overlooked lesson: lateral markets aren’t dead zones. They are accumulation zones. The trick is to keep buying even when your statement looks like a flat line.
Geographic diversification sounds like a cliché, but during the 1970s it was a lifesaver for those who practiced it. The United States experienced both high inflation and high unemployment. But other countries had different mixes. Japan had relatively low inflation in the early 1970s, around 5% during the 1973 oil crisis, compared to double digits in the U.S. Switzerland kept inflation under 3% for most of the decade by letting its currency appreciate. The Swiss franc rose so much against the dollar that a Swiss investor holding U.S. stocks in the 1970s actually made positive real returns because the currency gains offset inflation.
The practical application for today is straightforward: do not concentrate all your equity exposure in one country, especially one with large fiscal deficits and a history of inflation surprises. I allocate a meaningful portion of my stock holdings to markets in Asia and Europe, specifically to countries with independent central banks and low debt-to-GDP ratios. Places like Australia, Singapore, and Sweden did well during periods of global commodity inflation because they are resource-rich or have strong export bases.
There is also the frontier market angle. A few investors in the 1970s looked beyond developed nations to countries like Malaysia and Chile, which had commodity booms that insulated their economies from stagflation. That carries more risk, but the principle holds: when your home market is stuck in a low-growth, high-inflation rut, there is almost always some region in the world that is experiencing the opposite.
So where does this leave someone trying to prepare for the possibility of a similar scenario today? I’ve distilled a short checklist I run through each quarter. It’s not perfect, but it keeps me honest.
First, do I have at least 15% of my portfolio in real assets that have a direct link to inflation? That includes commodities, commodity equities, real estate, and inflation-linked bonds. Second, do my stock holdings include businesses with demonstrated pricing power—companies that maintained margins through the 2022 inflation surge? Third, have I avoided long-duration fixed income unless it is explicitly inflation-adjusted? Fourth, am I prepared to hold through a decade of sideways action without panic selling? That last one is psychological, but I test it by imagining my portfolio down 30% while the news screams recession. If that scenario keeps me awake, I’m overleveraged. Fifth, is my geographic exposure diversified enough that a localized stagflation in the United States or Europe would not crush my entire net worth?
I don’t claim to have perfect answers. The 1970s were messy, confusing, and full of surprises. But they also offered a rare kind of clarity: in an inflationary, stagnant economy, the winners are those who own what others need, collect income that rises with prices, and refuse to be shaken out by fear. That playbook is seventy years old, but it has not aged a day.
