Financial markets experienced significant turbulence Monday following weekend military operations conducted by the United States and Israel targeting Iranian facilities. Investors had their first opportunity to react to the escalating conflict, and the response was swift and decisive.
Bitcoin slid to $66,702, representing a 1.1% decline over the previous 24-hour period. The drop reversed much of Sunday’s temporary climb to $68,000, which occurred after reports confirmed Supreme Leader Khamenei’s passing.

The broader cryptocurrency market mirrored Bitcoin’s weakness. Ether decreased 2.5% to reach $1,967, while Solana tumbled 4.1% to $84, and XRP shed 3.6% to settle at $1.36. Examining the seven-day performance, Solana experienced the steepest decline among prominent digital currencies, falling 8.1%.
The military action followed Iran’s refusal to comply with U.S. requirements to curtail its nuclear development activities. Officials in Tehran have vowed significant retaliation, intensifying worries about potential regional escalation.
Oil prices experienced dramatic movement in response to the developments. Brent crude initially spiked 13% at market open before moderating to approximately $77.50, maintaining a 6.4% gain. This represents the most substantial daily advance since the February 2022 Russian invasion of Ukraine.
West Texas Intermediate, America’s primary oil benchmark, hovered near $73 per barrel. Iran ranks as OPEC’s fourth-largest petroleum producer, amplifying supply concerns.
According to Bloomberg reports, the Strait of Hormuz, a waterway carrying approximately 20% of global oil shipments, has become effectively impassable. This development is intensifying price pressures and creating anxiety throughout international energy markets.
Stock Futures and Safe-Haven Assets React
U.S. equity index futures experienced widespread declines of roughly 1%. Dow Jones futures plummeted more than 500 points, while S&P 500 and Nasdaq 100 futures fell approximately 1.4% and 1.8% respectively. Asian stock markets declined 1.4%.

Gold advanced to $5,350 per ounce as market participants sought refuge in traditional safe-haven investments.
The S&P 500 had already concluded February with losses. Heightened volatility affecting artificial intelligence and software sector equities had created market uncertainty entering the new week.
Escalating energy costs are amplifying inflation anxieties. Should inflation accelerate, the Federal Reserve might postpone interest rate reductions, potentially constraining market liquidity and creating additional headwinds for risk-sensitive assets including equities and cryptocurrencies.
What Traders Are Saying About Crypto’s Downside Risk
Certain cryptocurrency market participants suggest the potential downside for digital currencies might be contained. Jeff Mei, COO at BTSE, noted Iran’s longstanding isolation from international financial systems has diminished the direct impact on cryptocurrency markets.
Mei further suggested that expanded production from OPEC members and U.S. producers could compensate for reduced Iranian oil availability and eventually stabilize pricing.
Contradictory information surfaced Monday regarding potential nuclear negotiations between Iran and the United States. While The Wall Street Journal indicated Iran might pursue diplomatic talks, the nation’s national security chief categorically denied any intention to negotiate.
President Trump stated military operations would persist until strategic goals are achieved.
Investors will focus on upcoming corporate earnings from Broadcom and Marvell Technology this week, alongside retail sector results from Target and Costco. Friday’s February employment report arrives with analysts projecting 60,000 job additions.
