What's Happening With Iran — And What It Means for Your Portfolio

As you may have seen in the news, peace talks between the U.S. and Iran broke down last weekend after 21 hours of negotiations in Pakistan. The two sides agreed to a two-week ceasefire earlier this month, which briefly sent stocks higher and oil prices lower, but without a deal in place, that uncertainty is back. The core issue for markets is the Strait of Hormuz, the waterway that carries roughly one-fifth of the world's oil supply, which Iran has effectively kept closed since the conflict began in late February. Energy prices have surged, inflation concerns are back on the table, and the ceasefire itself expires April 22 with no clear path forward.

Staying Grounded When the Headlines Are Concerning

It is important to keep events like these in perspective, both when markets are down and when they are up. Ceasefires are genuinely positive developments, especially from a humanitarian standpoint, but history reminds us to be cautious. The ceasefires between Israel and Hamas and between Russia and Ukraine were fragile and did not always hold, and the same dynamic is playing out now with Iran. The chart below illustrates the pattern well: major geopolitical events have consistently caused short-term market volatility, but they have rarely derailed long-term performance. That history is directly relevant here. For investors, the discipline is staying focused on your plan rather than reacting to headlines that may look very different a year from now.

Energy Prices and the Inflation Comeback

The U.S. is now planning to blockade the Strait of Hormuz, and oil prices have climbed back above $100 per barrel as a result. That reversal matters because the Strait carries roughly 20% of global oil consumption, and when it is effectively closed, the world feels it at the pump and across supply chains. Oil had dropped sharply after the ceasefire was announced, but that relief has faded quickly, which is a good illustration of just how sensitive markets are to developments in this conflict.

The jump in fuel costs, even if it proves temporary, is expected to push headline inflation higher. Energy is one of those expenses consumers cannot easily avoid, and it feeds into the price of almost everything else. The OECD has estimated that U.S. inflation could rise faster than expected in 2026, and the IMF's latest projections point in the same direction, warning that all roads lead to higher prices and slower growth. Neither of those outcomes is guaranteed, and the situation could shift quickly if diplomacy resumes. But they are worth understanding so that none of this catches you off guard.

Markets Are Moving — Here Is What to Make of It

Stock markets initially responded well to the ceasefire announcement, with major indices recovering some of their losses from earlier this year. That optimism has since pulled back alongside the renewed tensions. Since late February, both oil and equities have swung sharply in both directions, sometimes within the same week, which reflects just how much uncertainty is still priced into markets right now.

What history tells us is that the underlying economic conditions matter more than the geopolitical event itself. The conflicts that proved most disruptive to long-term investors were typically those that coincided with weak fundamentals, not the headlines alone. That does not mean ignoring what is happening, but it does mean not letting the news drive decisions that your long-term plan already accounts for.

Bottom Line

Geopolitical crises are unsettling by nature, and this one is no exception. But the clients who navigate them best are usually the ones who resist the urge to act and trust the plan they put in place before the headlines got loud. Staying diversified and keeping a long-term perspective are not just phrases we repeat in moments like this — they are the strategy. If you have questions about how any of this affects your specific situation, we would welcome the conversation.
