Bitcoin Faces Pressure as Strait of Hormuz Reopening Turns Fragile
By John Nada·Apr 18, 2026·4 min read
Bitcoin's recent surge is threatened as Iran re-closes the Strait of Hormuz, raising concerns over oil supply and market stability ahead of a critical ceasefire deadline.
Bitcoin's recent surge to an intraday high of $78,336 coincided with a brief reopening of the Strait of Hormuz, but the situation has rapidly deteriorated. Following Iran's announcement on April 17 that the strait would be opened during a ceasefire, oil prices experienced dramatic declines, with Brent crude falling 12.95% to $86.52 and WTI dropping 14.26% to $81.19, both their lowest levels since March 11 and the largest single-day declines since April 8. This price action reflects traders stripping the war premium from crude prices, leading to a broader risk-on environment across financial markets. However, just one day later, Iran closed the strait again, creating uncertainty ahead of the April 22 ceasefire deadline.
The reopening had allowed only eight oil and gas tankers to transit, highlighting the fragility of the situation. The Strait of Hormuz is crucial, accounting for about 20% of global petroleum liquids consumption, meaning disruptions here can have significant implications for global oil supply and pricing. As the market counts down to the ceasefire deadline, the stakes are high for both oil and Bitcoin. The interconnectedness of these markets is evident as Bitcoin's trajectory now hinges on oil prices and inflation expectations.
The recent drop in oil prices could alleviate inflation concerns, shifting market expectations about the Federal Reserve’s interest rate path. Traders have begun to price in potential rate cuts by December 2026, which could provide a supportive macro backdrop for Bitcoin. If the ceasefire holds and shipping normalizes, Bitcoin could benefit from a favorable macro environment, but the risks remain significant. Iran's operational message on April 17 closely mirrored earlier statements by its deputy foreign minister, indicating that ships could pass with Iranian coordination, yet actual traffic fell below 10% of normal levels.
This underscores the precariousness of the situation, as even during the brief reopening, commercial vessels required authorization from Iran's Ports and Maritime Organization and the Islamic Revolutionary Guard Corps (IRGC). The stringent measures imposed by Iran included the necessity to transit through designated safe lanes, which highlights the control Iran maintains over maritime movements in this critical waterway. The broader context reveals a market that has been rattled by geopolitical tensions, as the US blockade on Iranian shipping remains fully in place until a broader diplomatic settlement is achieved. As of April 18, Iran declared the Strait closed again, pushing the market back into a countdown toward the April 22 ceasefire deadline.
The limited movement of only eight oil and gas tankers during the reopening period signals how far the route remains from anything resembling normal traffic. Shipping companies have been hesitant to resume normal operations, waiting for legal and safety clarity before proceeding. The International Maritime Organization (IMO) has not confirmed that the arrangements met freedom-of-navigation standards, further complicating the situation. The US Navy has also stated that the mine threat in parts of the Strait of Hormuz is not fully understood, which adds another layer of uncertainty for shipping operations.
During the brief window of reopening, a Pakistani-flagged tanker carrying approximately 440,000 barrels of UAE crude successfully exited the Gulf on April 17, providing concrete data that passage was indeed possible. However, this isolated instance did not lead to normalization of shipping traffic, emphasizing the challenges ahead. The market is now caught between the fast pricing of a reopening and the stark reality that, as of April 18, the Strait is closed again, just days before the crucial ceasefire deadline. The arithmetic of fear looms large, as EIA data projects an average daily oil flow through the Strait at 20 million barrels in 2024, which constitutes roughly 20% of global petroleum liquids consumption.
This factor alone indicates the concrete threshold behind the market’s countdown: unless traffic recovers before April 22, the route that carries about one-fifth of global petroleum liquids remains functionally impaired. Since the conflict began, more than 500 million barrels of crude and condensate have been knocked out of the global market, translating to about $50 billion in lost output. Comparatively, global onshore crude inventories dropped roughly 45 million barrels in April alone, highlighting the impact of the ongoing conflict. As recently as April 7, the EIA had projected Brent averaging $115 in the second quarter, and on April 13, Morgan Stanley estimated Brent at $110 in the second quarter and $100 in the third quarter.
Now, with Brent at $86.52, it sits materially below every major published baseline from less than two weeks ago. This rapid shift indicates that the market has front-run a normalization path that neither the EIA nor Wall Street had anticipated. The fragile nature of the reopening is underscored by Iran's continued control and the unresolved tensions in the region. A durable ceasefire could lead to a recovery in oil traffic, easing price pressures and supporting risk assets like Bitcoin.
