The Retired Investor: Refresher on Geopolitical Events & the Stock Market

Iran is on everyone's radar screen. Markets are tumbling. Oil is skyrocketing, and explosions echo throughout our evening news shows. You may be nervous but remember that we have been here before.

 

And while war is a monstrous thing, its impact on your stock market investments is negligible. Last summer, I remember reading a J.P. Morgan research report that listed 36 geopolitical events between 1940 and 2022 that we could call crises. What they found was that in the first three months after an event, markets do underperform.

 

However, if you look at returns six and 12 months later, it was as if the risk event had never happened. You might know this, but in the heat of battle, many investors let emotions override their objectivity. Don't do it.

 

This conflict, although less than a week old, is playing out just like so many others. There has been a sharp sell-off in stocks and a flight to quality into the U.S. dollar. Energy prices, both for oil and gas, have also spiked, as they did on several prior occasions, most notably in 1973 and at the onset of Russia's invasion of Ukraine in 2022.

 

This time around, however, gold and even U.S. Treasury bonds, which are usually a "go-to" in times of geopolitical strife, have not responded as expected. It is unusual since gold has historically been one of the best-performing hedges against war risk. It may be that gold has already had a spectacular run both in 2025 and thus far in 2026. That may mean traders are hesitant to chase the price higher.

 

This war could curtail both energy shipments and production. Investors fear that rising energy prices may spark a resurgence in inflation. This is one reason the yield on longer-dated U.S. Treasury bonds spiked rather than fell. Higher yields and a stronger dollar — both antithetical to gold and other commodities — could also explain gold's poor performance.

 

Higher energy prices are among the main determinants of inflation, as energy permeates almost every aspect of the economy. The longer and steeper the price of oil and gas climbs, the higher the inflation rate. Herein lies the risk of the present conflict between Iran and the U.S.

 

Normally, as I said, wars in the past have had little to no impact on equity market returns on a one-year horizon; there have been exceptions. The 1973 oil crisis did have a lasting impact on returns. The reason had everything to do with a prolonged oil supply shortfall. That resulted in a two-fold hit to the U.S. economy as growth slowed and inflation rose, producing a period of stagflation.

 

This time around, we have a completely different scenario when discussing the energy markets. Back in 1973, America relied heavily on Middle Eastern oil, while U.S. production was already as high as it could be given the technology available at the time.

 

Today, the U.S. is among the world's leading energy producers, and the worldwide supply of oil and gas is plentiful. Bringing more of these resources online while the conflict continues may temporarily disrupt global markets, but few expect the energy shortfall to linger for many years. Remember 2022, the Russia/Ukraine war also spiked oil prices, but they quickly fell as additional oil supply came online.

 

We are in an era where trade wars, real wars, and repeated supply shocks challenge the world's economies and will continue for at least the next decade. Older generations must relinquish control so new leaders can guide us.

 

Unlike in prior decades, these new threats cannot be managed by an interest rate cut, a little more fiscal spending, or a protest march. Shocks to the system, whether through conflict, political and/or climate change, artificial intelligence, or pandemics, will require new leadership and policies. It is an age where economic and political relationships have been upended, and that, my dear reader, will continue.
