The Strait of Hormuz carries 20% of the world's oil. With it effectively closed, here's what that means for prices, inflation, and your wallet.
The Strait of Hormuz is a narrow waterway between Iran and Oman. About 20% of the world's oil passes through it every day. When it's open, most people never think about it. When it's not, everything changes.
The ongoing US-Iran conflict has effectively disrupted shipping through the Strait of Hormuz for weeks. The International Energy Agency has called it "the largest supply disruption in the history of the global oil market." Brent crude — the international benchmark for oil prices — has surged from around $67 per barrel in early February to roughly $110 today. That's a gain of more than 60% in under two months.
Last week, US President Trump warned of intensified military action over the coming weeks, while Iran's parliament speaker responded that the country is "armed, prepared, and standing firm." Diplomatic channels through Oman have offered brief moments of hope, but no lasting resolution.
Oil prices affect almost everything. When crude rises sharply, it flows through to gasoline, shipping costs, food prices, and manufacturing. For everyday consumers, that shows up at the pump and the grocery store.
Inflation pressure — Central banks, including the US Federal Reserve, were already struggling to bring inflation back to target. The IMF recently noted the Fed has "limited room" to cut interest rates this year. Higher oil prices make that job harder.
Emerging markets get hit hardest — Countries like Turkey, India, and much of Southeast Asia import most of their oil. Turkey's central bank reserves have already dropped significantly — gross reserves fell from $177.5 billion to $155.3 billion in recent weeks. A weaker currency plus expensive oil imports is a painful combination.
OPEC+ is watching — Reuters reports that OPEC+ may discuss a production increase at its upcoming meeting. If confirmed, additional supply could take some pressure off prices. But replacing the Hormuz shortfall entirely is difficult — no single producer or route can easily substitute that volume.

Oil supply disruptions don't stay in the oil market. They ripple through inflation, interest rates, currencies, and everyday prices. The Strait of Hormuz crisis is already the biggest supply shock in modern history, and until there's a resolution — diplomatic or otherwise — the effects will keep building.
