The reopening of the Strait of Hormuz is triggering a rapid unwind of geopolitical risk across global markets. As of 17 April 2026, the resumption of energy and fertiliser flows is removing a key supply shock that had driven volatility across assets. This shift is forcing a repricing of oil, currencies and equities, with investors reassessing inflation and growth expectations. The speed of this adjustment highlights how tightly global markets remain linked to critical trade infrastructure and geopolitical developments.
Fiona Cincotta, StoneX Senior Market Analyst, has extensive experience analysing cross-asset market reactions to macroeconomic and geopolitical shifts. Her perspective is grounded in tracking how energy price shocks and currency flows interact, giving her a distinct view on how quickly risk sentiment can reverse when supply disruptions ease.
Key Themes from the Discussion
Strait of Hormuz reopening allows energy supply to flow freely again, easing supply fears.
Oil prices fall 10 percent toward 80 dollars per barrel, driving a sharp unwind of the war-driven risk premium.
U.S. dollar weakens and global equities rally as safe-haven demand fades and risk sentiment improves.
Oil prices are leading the unwind of geopolitical risk as flows resume through the Strait of Hormuz. Fiona Cincotta confirms that "oil prices have fallen sharply, down 10%, moving back toward $80 per barrel", reflecting the rapid removal of supply disruption fears. This decline is easing cost pressures across global economies, particularly those heavily reliant on imported energy. As a result, lower oil prices are directly reducing inflation expectations and improving the outlook for growth-sensitive sectors.
U.S. Dollar Weakens as Risk Appetite Returns
The U.S. dollar is declining as safe-haven demand unwinds alongside geopolitical tensions. Cincotta highlights that "the U.S. dollar has weakened by around 0.5%, trading back at pre-war levels", signalling a shift away from defensive positioning. This movement is encouraging capital to rotate into riskier assets, including equities and higher-yielding currencies. However, the sustainability of this trend depends heavily on whether geopolitical stability is maintained in the coming weeks.
Frequently Asked Questions
Why does the Strait of Hormuz matter for markets?
The Strait of Hormuz is a key global trade route for energy and fertilisers, with around 20 percent of global energy supply passing through it. Any disruption can significantly impact prices and market sentiment.
Why did oil prices fall after reopening?
Oil prices fell because the reopening reduced supply risk, removing the geopolitical premium that had been built into prices during the conflict.
What is the main risk for markets now?
The main risk is that markets may be pricing in a full resolution to the conflict, which could reverse if peace talks fail or tensions escalate again.
