Energy shock and geopolitics realign markets as dollar regains strength

Global markets were jolted on Monday as a renewed escalation in the Strait of Hormuz triggered a sharp repricing across energy and currency markets, pushing oil prices higher and lifting the US dollar as investors repositioned for a prolonged inflation shock.

The US Dollar Index climbed to around 98.3, recovering part of last week’s losses, as safe-haven demand returned following reports that the US Navy fired on and seized an Iranian-flagged vessel in the Gulf of Oman. The incident marked a significant deterioration in US-Iran relations, with Tehran signaling it would not proceed with further negotiations and reversing plans to reopen the Strait of Hormuz.

At the same time, oil markets reacted aggressively. West Texas Intermediate crude surged more than 6% toward $89 per barrel, while Brent crude rose over 5% to above $95, reflecting a rapid reintroduction of geopolitical risk premiums tied to one of the world’s most critical energy corridors.

The synchronized move underscores a key shift in market dynamics: energy and currency markets are once again tightly coupled through geopolitical risk and inflation expectations.

The escalation comes at a critical moment. Markets had begun to price in a path toward de-escalation and eventual rate cuts, but the renewed conflict has reversed that narrative, forcing investors to reassess both the inflation outlook and the trajectory of US monetary policy.

The Federal Reserve is now widely expected to keep rates unchanged in the near term and potentially maintain a restrictive stance throughout 2026, as rising energy prices threaten to reaccelerate inflation after a period of gradual cooling.

The current market reaction is not just a response to a geopolitical event - it is a structural repricing of risk across the global macro framework. The combination of rising oil prices and a strengthening dollar reflects a shift back toward a “shock-driven” environment, where supply disruptions dominate economic expectations.

The Strait of Hormuz sits at the center of this dynamic. Any disruption in this corridor has immediate implications for global oil supply, and by extension, inflation. The 5 – 6% surge in oil prices in a single session signals that markets are assigning a higher probability to sustained disruption rather than a temporary flare-up.

For the dollar, the move higher is driven by two reinforcing mechanisms. First, safe-haven demand increases as geopolitical uncertainty rises. Second, higher oil prices feed into inflation expectations, reducing the likelihood of near-term rate cuts and supporting US yields.

However, this relationship is not linear. A prolonged energy shock could eventually weigh on global growth, including the US economy, potentially reversing dollar strength over a longer horizon. This introduces a time-dependent dynamic, where the dollar strengthens in the short term but faces structural pressure if the shock evolves into a broader economic slowdown.

The most important shift is in monetary policy expectations. Just days ago, markets were positioning for a gradual easing cycle. Now, that narrative is being pushed further out. Energy-driven inflation acts as a constraint on central banks, limiting their ability to support growth even as risks increase.

This creates a stagflationary tension: higher prices combined with weaker growth prospects. In such an environment, traditional policy tools become less effective, and market volatility tends to increase.

From an investment perspective, the alignment between oil and the dollar is a key signal. When both move higher simultaneously, it indicates that markets are pricing in stress rather than growth. This is fundamentally different from a demand-driven rally, where rising oil would typically weaken the dollar.

Ultimately, the current setup is defined by a binary outcome. If tensions escalate further, oil and the dollar are likely to continue rising, reinforcing inflation and tightening financial conditions. If diplomacy resumes, both could reverse sharply, restoring risk appetite and easing pressure on central banks.

For now, markets are clearly leaning toward the former scenario: a prolonged period of uncertainty, elevated energy prices, and delayed monetary easing.
