Iran’s foreign minister, Abbas Araghchi, said on Friday that after the ceasefire in Lebanon, all commercial shipping through the Strait of Hormuz would be fully open for the rest of the ceasefire period. He said vessels would use a coordinated route set out by Iran’s Ports and Maritime Organisation.
US President Donald Trump posted on Truth Social that the Strait of Hormuz was open for “full passage”. He said a naval blockade would still apply to Iran until a US-Iran transaction was “100% complete”, and said the process should move quickly because most points are already negotiated.
Following the reports, US stock index futures were up between 0.8% and 1.2% at the time of publication. The US Dollar Index (DXY) was below 97.70, its lowest level since late February, and was down more than 0.5% on the day.
The opening of the Strait of Hormuz, even with a specific blockade on Iran, should lower the geopolitical risk premium baked into oil prices. This key waterway sees about a fifth of the world’s daily oil supply pass through it, and recent tensions had kept WTI crude futures trading above $95 a barrel through March of 2026. We should consider strategies that benefit from falling oil prices, such as buying put options on crude futures expiring in the next two to three months.
This news is also a clear signal to expect a decline in broad market volatility. The CBOE Volatility Index (VIX) will likely fall from its current levels in the low 20s, much like we saw during the temporary de-escalation in the spring of 2025 when it dropped nearly 30% in two weeks. Selling out-of-the-money call spreads on the VIX or VIX-related ETFs offers a way to capitalize on this expected return to calm.
Lower energy costs directly combat the inflation concerns that have been weighing on the market this year. With the latest March 2026 Consumer Price Index report showing inflation still stubbornly high at 3.1%, this development could give the Federal Reserve more justification to proceed with a potential rate cut this summer. This improves the outlook for equities, making bullish call options on the S&P 500 index attractive.
The US Dollar’s decline is a direct result of this risk-on sentiment, as capital flows from the safety of the dollar to higher-growth assets. We have seen the DXY drop below 97.70 for the first time since February 2026, a significant technical breakdown. This trend supports taking bearish positions on the dollar through options on currency ETFs.
However, the situation remains fragile, as the blockade on Iran is still in full effect pending completion of a “transaction.” Any negative headlines from these negotiations could cause a rapid reversal in sentiment, snapping oil prices and volatility higher. We must therefore keep our position sizes moderate and use defined-risk option strategies to protect against a sudden shift.
