Portfolios During Inflation

How major asset classes have historically behaved when inflation ran hot.

During past periods of sustained high inflation, asset performance has followed a recognizable historical pattern: commodities and gold have tended to outperform, inflation-protected bonds have preserved purchasing power better than nominal bonds, long-duration nominal bonds have been the most consistent losers in real terms, and equities have landed in between — hurt while inflation accelerated, recovering once it peaked. Cash has lost purchasing power steadily but less catastrophically than long bonds.

This page summarizes that historical record across the major US inflation episodes, shows whether the inflation regime is active right now, and links the live indicators behind each claim. It describes what happened in the past; it is not a forecast and not personalised advice.

The historical pattern, episode by episode

In the 1970s — the defining US inflation decade — gold and commodities delivered strongly positive real returns, while both stocks and bonds spent years underwater in inflation-adjusted terms. Equities' price-earnings multiples compressed even as nominal earnings grew, and long Treasuries suffered their worst sustained real losses of the century.

In 2021-2023, the pattern rhymed: commodities and energy equities led while inflation accelerated, nominal bonds had their worst calendar year in modern records (2022), TIPS outperformed nominal Treasuries of matching maturity, and broad equities fell during the acceleration phase before recovering as inflation rolled over.

The consistent thread across episodes is that the direction of inflation mattered more than its level: accelerating inflation was historically the hostile phase for stocks and bonds alike, while decelerating-but-still-high inflation often coincided with strong equity recoveries.

Why the pattern looks like this

Nominal bonds promise fixed payments, so unexpected inflation directly erodes their real value — and the longer the maturity, the larger the hit. Commodities sit on the other side of the same coin: they are inputs to the prices being measured, so they tend to rise with, and often ahead of, the index.

Equities are claims on real businesses, which can eventually reprice their products — but the adjustment is uneven. Historically, companies with pricing power and short-duration cash flows weathered inflation better than long-duration growth stories whose value sits far in the future.

Gold's record is more episodic than commodities': strongest when real interest rates were negative — when inflation outran bond yields — and weaker when central banks pushed real rates decisively positive. The real interest rate chart linked below tracks exactly this condition.

Is the inflation regime active now?

MacroRadar's regime model classifies the current US inflation dimension continuously from live data — see the Current Macro Regime page for today's reading, and the inflation, core inflation, and breakeven charts linked below for the raw series behind it.

The regime-based allocation book on the Portfolios page shows how a rules-based historical allocation has responded to inflation regimes, backtested on point-in-time data with its limits reported.

Limits of the historical record

There are only a handful of true US inflation episodes in the modern data — small samples invite overconfident conclusions. Each episode also had its own cause (oil embargo, pandemic supply shock, monetary expansion), and asset behavior differed with the cause.

Past performance during inflation regimes does not predict future performance, and nothing here accounts for any individual's circumstances. This page reports what happened; deciding what to do with that record is yours, ideally with professional advice.

Frequently Asked Questions

What assets have historically done best during inflation?

Commodities and gold have the strongest historical record during US inflation episodes, followed by inflation-protected bonds (TIPS), which preserved purchasing power better than nominal bonds. Value stocks and short-duration assets held up better than long-duration growth stocks. This describes the historical record, not a recommendation.

Are stocks a good inflation hedge?

Historically, poor during accelerating inflation and much better after inflation peaked. Over multi-decade horizons equities have outpaced inflation, but within inflationary episodes they typically fell in real terms during the acceleration phase — the 1970s and 2022 both fit this pattern.

Why do bonds lose money during inflation?

A bond's payments are fixed in nominal dollars, so higher inflation makes each future payment worth less in real terms — and rising yields push existing bond prices down. The longer the bond's maturity, the larger both effects; 2022 was the clearest modern example.

Does gold always rise with inflation?

No. Gold's strongest historical performances came when real interest rates were negative — inflation running above bond yields. When central banks raised real rates decisively, as in the early 1980s, gold fell despite still-high inflation. The real rate, not inflation alone, has been the historically decisive variable.

Is this investment advice?

No. This page summarizes the historical record of asset performance during past US inflation episodes. It is descriptive, not predictive, and not personalised to anyone's situation.
