(SeaPRwire) –   Bitcoin demonstrated more stability compared to oil and stocks this Monday as tensions between the U.S. and Iran escalated over the weekend.

The U.S. Navy apprehended an Iranian vessel identified as the TOUSKA, and President Trump announced on Truth Social that U.S. Marines had taken possession of the ship. He also cautioned about potential attacks on Iranian power plants and bridges if diplomatic efforts falter.

BREAKING: Iran says it has attacked US military ships with drones in retaliation for the US striking and seizing an Iranian cargo vessel in the Strait of Hormuz, per Tasnim.

In response, Tehran reinstated controls over the Strait of Hormuz, a critical global oil shipping lane. Iran had previously declared the strait “completely open” on Friday, a development that contributed to the S&P 500 reaching a record close that same day.

By Sunday, this optimism had dissipated.

On Monday morning, Bitcoin was trading at $74,335, marking a 1.6% decrease over a 24-hour period. Despite this, it remained up 4.8% for the week. This marks the fourth significant Iran-related market shock that cryptocurrencies have weathered since the conflict began, with each subsequent sell-off being less pronounced.

Ether declined by 2.6% to $2,272. Solana fell 1.5% to $84, and BNB remained stable at $618. None of the top 10 cryptocurrencies experienced a drop exceeding 3%.

Oil and Stock Markets Experience Greater Impact

The oil markets reacted significantly. Brent crude prices surged by 5.7% to $95.50 per barrel, while WTI crude saw an approximate 6.9% increase, reaching just under $90 per barrel. European natural gas futures climbed as much as 11%.

Gold decreased by 0.8% to $4,790. The dollar strengthened slightly as investors sought traditional safe-haven assets.

U.S. stock futures experienced a downturn. Dow futures dropped by approximately 0.7%, while S&P 500 and Nasdaq 100 futures each fell by about 0.6%. European equity futures indicated a potential 1.2% decline at the opening of Monday’s trading session.

The weekend’s escalation reversed three weeks of diminishing war risk across markets. Equities and emerging markets had seen broad rallies on Friday following Iran’s announcement that the strait was open.

Bitcoin’s Pattern Amidst Iran Developments

With each instance of Iran-related news impacting markets since the conflict began, Bitcoin’s price decline has become progressively smaller. Analysts suggest this trend may be attributed to holders who intended to sell on geopolitical news having already done so.

The increasing presence of spot Bitcoin ETFs could also be contributing to a more stable price floor.

Traders were observing whether the 10-year Treasury yield, currently near 4.27%, and a stronger dollar would exert downward pressure on Bitcoin through broader risk channels.

Bitcoin was trading near $74,000 as the European trading session commenced on Monday morning.

Looking ahead, investors are also anticipating a busy earnings week, with reports expected from Tesla, Intel, and United Airlines.
