May 2026 Market Commentary

May 14, 2026


Before I talk about oil prices and inflation scenarios following recent military conflict involving Iran and disruptions to the Strait of Hormuz, a critical chokepoint for global oil supply, I want to focus on some of the market positives.

After a lousy March, the S&P 500 recovered quickly and is up over 8% year-to-date. International developed and emerging market indices have grown 11% and 9% respectively, and US small caps are up over 10%, too. A diversified 60/40 portfolio is up about 8% as well, showing how markets have remained resilient in the face of geopolitical volatility, higher oil and gas prices, and rising inflation.


Jordan Jackson and Brandon Hall with JP Morgan tried to answer the question of, “How Inflationary is the oil price spike?” earlier this month. The different scenarios they outlined can be summarized as the good, the ehh, and the ugly and each scenario depends on the length of the conflict in Iran and, more specifically, the Strait of Hormuz.

Scenario 3: Rapid Resolution – Inflation near peak and declines gradually

The Good. “If diplomacy moves faster than expected and oil prices normalize gradually, headline CPI could revert to the average monthly pace seen in the year ending February 2026. Even in this benign scenario, inflation would still remain above 3.0% through February 2027.”

Scenario 2: The 2022 Playbook – Inflation peaks at 4% but declines quickly

The ehh. In 2022, Russia invaded Ukraine and oil prices spiked through the first half of they year, pushing inflation higher due to higher energy prices. If the current state of the conflict persists, investors can expect similarities. It’s worth noting in 2022, we were dealing with the economy opening back up post-Covid, supply chain problems, and inflation already running very hot. While 2022 was a bad year for markets and inflation, “Today’s starting point is much lower, and with demand expected to weaken modestly and disinflationary forces still intact, peak inflation this year should fall well short of 2022’s high.”

Scenario 1: Re-escalation – Inflation peaks over 5% and remains elevated

The Ugly. The US and Iran re-escalate, the Strait remains impassable and even more dangerous, and more damage is caused to the broader oil and energy infrastructure. A week ago, the final tanker from the Strait of Hormuz made it to California before the closure, so a re-escalation will further shock markets and push oil and gas prices higher.


Even in the more challenging scenarios, inflation trends back toward normal over time.

Each scenario carries different market implications, but at PDS Planning we’re prepared for any of them. For clients holding cash, today’s environment still offers attractive options. Money markets near 3.5% and CDs around 4% mean your cash is working while waiting for the right opportunities. We’re also actively monitoring portfolios for rebalancing needs as markets shift and watching for tax-loss harvesting opportunities as volatility creates them. Whatever the conflict resolution looks like, we’ll be ready to act, and we’re always just a conversation away if you have questions.
