When the Iran‑Israel war constricts oil flow through the Strait of Hormuz, markets react with jittery swings that can spook even seasoned investors. Yet, as the Associated Press reports, seasoned advisers warn that the best defense for retirement savings is still to stay the course.

The conflict has effectively halted most traffic in the Strait of Hormuz, a narrow channel that normally ferries about a fifth of the world’s daily oil supply. That bottleneck pushed crude prices up to nearly $120 per barrel on Monday, the highest level since the summer of 2022, and some analysts fear prices could climb toward $150 if the waterway remains blocked.

For U.S. investors, the immediate impact is heightened volatility in the equity markets. The S&P 500 closed 4.4% below its all‑time high set in January, with the Dow Jones Industrial Average experiencing intraday drops of roughly 900 points that later receded. Such swings feel unnerving, but they fit a familiar pattern: the index has historically rebounded from every major shock, whether it be a global financial crisis, a trade war, or a pandemic‑induced downturn.

“Although volatility may feel uncomfortable, could rise from here, and possibly cause a near‑term drawdown in stocks, volatility in itself tends to be brief when it reaches more extreme levels,” Anthony Saglimbene, chief market strategist at Ameriprise, said. “And, more often than not, the extreme volatility provides investors with a solid long‑term entry point to buy stocks rather than sell.”

Financial advisers stress that the key is time. Investors who can keep money out of the market for several years — up to a decade in some cases — are far less likely to suffer irreversible losses. For younger investors, having decades until retirement offers a natural buffer: they can afford to ride out downturns and benefit from the market’s long‑term growth trajectory. Older investors, especially those near retirement, are cautioned to balance exposure with safer assets, but even they are urged to avoid panic‑driven withdrawals that lock in losses.

Pulling money out of a 401(k) carries additional penalties. Besides potentially facing a 10% early‑withdrawal tax, investors also sacrifice any chance of recouping lost value as the market recovers. A 401(k) loan is an alternative, though it comes with its own set of restrictions.

Diversification remains a cornerstone of the recommended strategy. While Treasury bonds and gold often rise when stocks tumble, this cycle is muted this time because high oil prices and lingering inflation are also weighing on bond yields. Maintaining a mix of assets can smooth out the shocks.

No one can predict how long the current turbulence will last, and the markets will likely continue to oscillate as the war’s outcome remains uncertain. Nonetheless, the prevailing wisdom among professional investors remains unchanged: stay invested, stay patient, and use market dips as potential buying opportunities rather than reasons to exit.
