The Strait of Hormuz is closed again, Bitcoin and Ethereum ignore new U.S. strikes on Iran

Cryptocurrency markets react flat as U.S. launches new round of strikes on Iran

On Sunday, the United States launched a new round of strikes on Iran, the third military action this week. Tehran reportedly closed the Strait of Hormuz again. However, cryptocurrency traders were hardly moved. According to market data from the weekend morning, Bitcoin and Ethereum prices did not change much. This sign of a lack of safe-haven demand for assets on the chain suggests that the market is maturing and is no longer easily intimidated by conflicts in the headlines.

The blockade of the world's most important oil choke points usually causes violent shocks in risky assets and triggers a surge in safe-haven buying. But this time, Bitcoin is only hovering within its immediate range, and Ethereum's volatility is less than 1%. Offshore market liquidity remained thin over the weekend, but the overall situation was calm. This calm is itself a signal.

Why did cryptocurrencies respond so lukewarm to the closure of the Strait of Hormuz?

Historical experience shows that military strikes against Iran and threats to the Gulf Channel often trigger violent fluctuations in commodity and currency markets, and cryptocurrencies are sometimes affected. The last time Tehran actually closed the Strait of Hormuz was in 2025, when Bitcoin surged 4% in less than two hours before falling back. But this time, the script was completely reversed. The impact of the escalation has been absorbed by the market, which has become increasingly insensitive to geopolitical turmoil. At the same time, institutional capital flows that might otherwise have been diverted to Bitcoin in response to panic are now driven more by structured products and regulated channels.

Another factor is the dollar. When tensions in the Strait of Hormuz push oil prices higher, the U.S. dollar typically strengthens, offsetting safe-haven demand flowing to the largest cryptocurrencies. As Bitcoin and Ethereum trade more and more like large technology stocks, while the Volatility Index (VIX) falls and the Dollar Index (DXY) remains stable, these factors have combined to inhibit the performance of assets on the chain amid military headlines.

The silence of institutions and new hedging propositions

The cold reaction of the market also reflects changes in ownership structure. In the U.S. and Asia, cash flows from spot ETFs have concentrated positions in funds that are rebalancing on a calendar basis, rather than adjusting in response to panic. Weekend monitoring data from chain analysts showed no abnormal inflows from trading platforms, no sudden surge in stablecoin minting, and no large-scale transfer of assets from cold wallets to seller addresses. If there is any indication, the lack of activity itself suggests that spot holders are mostly institutional investors, and that these positions will not be easily sold off by a Sunday morning hit on Iran.

This does not mean that the risks have disappeared. The continued closure of the Strait of Hormuz will disrupt global crude oil and liquefied natural gas supplies, drive up inflation and force central banks to delay interest rate cuts. In this case, long-term assets, including cryptocurrencies, will eventually be hit. But traders have not yet connected those points, perhaps because the latest shutdown is seen as another temporary disruption rather than a permanent change. Markets are waiting to see whether the waterway can reopen within 48 hours-something that has occurred many times in the previous Strait of Hormuz crisis.

The regulatory background that hangs over the market

Although military action dominated the headlines over the weekend, the cryptocurrency market's attention was also distracted from domestic policy games. The crackdown comes just days after a major cryptocurrency bill is facing crisis in Washington, as banking interests try to shelve it ahead of a Senate vote. This legislative uncertainty serves as a hedge, allowing funds to choose to wait and see even in the face of geopolitical shocks. When the regulatory path is unclear, neither air strikes nor strait blockades are enough to provide a clear directional bet.

At the same time, developer activity on major blockchains remains active. The latest data shows that developers continue to invest in construction, reminding us of the growing disconnect between short-term price movements and network fundamentals. It is this disconnect that allows Bitcoin and Ethereum to absorb geopolitical noise without experiencing violent fluctuations like earlier cycles.

For now, markets appear to view the conflict as a controlled event. The key variable is how long the Strait of Hormuz will be closed. If it can reopen before U.S. markets open on Monday, it is likely to strengthen the narrative of cryptocurrency's resilience. Conversely, if the standoff persists, it will test whether the weekend's lull can withstand the brunt of risk repricing in bond, equity and commodity markets within a week. In any case, the weak response from cryptocurrency prices amid the third U.S. strike in a week and the closure of global shipping chokepoints marks a significant evolution in the way digital assets absorb world tensions.
