Hormuz Tanker Attack Lifts Oil, Rattles Crypto Markets

The Strait of Hormuz is a crucial route for Persian Gulf crude shipments to global markets, and any military conflict could raise transportation, insurance and energy costs. Dollar-denominated Brent crude and West Texas Intermediate (WTI) are key international benchmarks for tracking supply, demand and geopolitical risk.

The latest reports said Iran fired at least two missiles at a tanker in the Strait of Hormuz, prompting a rebound in Brent and WTI prices. The reports did not provide the date of the incident, per-barrel prices or the size of the gains. Analysts said market sentiment remained bearish, with the rally’s durability depending on how the conflict develops and whether crude supplies are actually disrupted.

The Strait of Hormuz is a vital route for Persian Gulf oil exports. To keep energy shipments moving, the U.S. military used covert ship-to-ship transfers and deployed Apache helicopters as escorts. After Iran shot down a helicopter, the United States retaliated militarily, escalating the conflict from a shipping-security dispute into direct hostilities. Rising oil prices also prompted investors to pull money from risk assets such as Bitcoin.

The latest reports revealed how the U.S. military covertly transferred oil, with at least one Apache helicopter shot down by Iran during an escort operation, triggering the U.S. retaliation. However, available information does not specify the exact date of the incident or the volume and value of the oil transferred. It also provides no figures for changes in oil prices or Bitcoin, leaving those numbers pending confirmation from official or market data.

The Strait of Hormuz carries about one-fifth of global oil shipments. Iran blocked the waterway in retaliation for U.S. and Israeli attacks, sharply reducing Middle Eastern crude supplies and pushing oil prices above $100 a barrel. Higher energy costs could fuel inflation and force the Federal Reserve to delay interest-rate cuts. A stronger dollar and tighter global liquidity could, in turn, weigh on risk assets such as Bitcoin.

As of July 19, Iran had shifted to “selective passage,” with its Foreign Ministry saying non-hostile vessels had passed safely after coordination. Morgan Stanley nevertheless forecast that the strait would not fully reopen this month, while Polymarket traders put the probability of a reopening at just 30%. The Wall Street Journal estimated that about 9 million barrels of daily supply had disappeared, while companies’ worst-case scenarios projected that oil could rise to $175 a barrel.
