Dollar index rebounds as US-Iran tensions and hawkish Fed stoke inflation and rate fears

The US Dollar Index (DXY) retraced the prior session’s decline and traded around 100.80 in Asian hours on Monday, reflecting firmer demand for the US dollar (USD) against a basket of six major currencies. Support came as geopolitical risk re-emerged around a potential US-Iran peace deal, keeping inflation concerns and the prospect of higher-for-longer interest rates in focus. A CNBC report said President Donald Trump threatened direct strikes on Iran should Hezbollah continue attacks on Israel, a move that darkened prospects for diplomatic progress even as Vice President JD Vance held a first round of talks with Iranian officials under an interim deal. Tehran also said it had again closed the Strait of Hormuz; Iranian state media reported negotiations were suspended, while other sources said discussions continued. Separately, the Federal Reserve kept rates unchanged last week and adopted a hawkish tone, with 9 of 19 policymakers projecting at least one rate hike this year and markets pricing a possible move as early as September.

US Dollar Strength, Fed Policy, and Energy Market Risk

Given the renewed strength in the US dollar, we should position for this trend to continue in the coming weeks. The Federal Reserve’s hawkish tone, with nearly half its policymakers now expecting a rate hike, provides a strong tailwind for the dollar. We are therefore considering adding to long US Dollar Index (DXY) futures positions, targeting a move back towards the highs seen in previous years. The closure of the Strait of Hormuz is a major inflationary threat that the market cannot ignore. Historically, this chokepoint handles about a fifth of the world’s total oil supply, so any disruption will cause a significant price spike. We believe long call options on WTI and Brent crude oil offer a direct way to trade this escalating geopolitical risk.

Interest Rate Strategies, Volatility, and Defensive Asset Positioning

This potential energy shock supports the Fed’s aggressive stance, as inflation remains stubbornly above the 2% target, much like the persistent 3.3% prints we saw back in mid-2024. Consequently, we are positioning for higher interest rates by looking at options on shorting Treasury bond futures. The market pricing in a rate hike as soon as September makes this a timely strategy. Combining geopolitical tension with interest rate uncertainty is a classic recipe for market volatility. We view the CBOE Volatility Index (VIX) as underpriced relative to the substantial risks of direct US-Iran conflict, which has historically pushed the VIX well above 30. We are buying VIX call options to hedge our broader portfolio and profit from an expected rise in market turbulence. A strong dollar and rising real interest rates create significant headwinds for non-yielding assets like precious metals. We are therefore cautious on gold and are exploring put options to capitalize on expected weakness. Similarly, we are becoming more defensive on equities, as a stronger dollar can negatively impact the earnings of multinational corporations.
