Bitcoin plunged below the $79,000 mark for the second time in two days as investor sentiment shifted from optimism to caution after a highly anticipated U.S.-China summit failed to deliver the outcomes markets had hoped for. The plunge came 24 hours after the cryptocurrency briefly tapped $82,000 following the U.S. Senate Banking Committee’s 15-9 vote to advance the CLARITY Act.

According to Bitstamp, the top cryptocurrency dipped to a low of $78,611 around 10 a.m. EDT on May 15 before quickly reclaiming $79,000. By 1:40 p.m. EDT, it was trading around $79,400, narrowing its 24-hour losses to just under 3%. After hitting $82,000 at least three times in the last five days, bitcoin appeared poised to close a turbulent trading week marginally lower, pulling its market capitalization below $1.6 trillion.

Billed as the most critical high-stakes diplomatic engagement between Washington and Beijing in years, the two-day summit concluded with no real trade breakthrough. Instead, the high-level talks served only to lay bare a deeply entrenched systemic rivalry, with the flashpoint issue of Taiwan’s sovereignty casting a long, ominous shadow over the entire proceedings.

By failing to break the diplomatic logjam over stringent U.S. export controls on advanced semiconductors and cutting-edge artificial intelligence hardware, the world’s two largest economic powerhouses have effectively guaranteed a prolonged escalation of their tech-centric trade war, according to geopolitical analysts.

While the two superpowers reportedly found common ground regarding Tehran’s nuclear ambitions and its recent closure of the Strait of Hormuz, the consensus was immediately overshadowed by fresh geopolitical turbulence. Speaking to pool reporters aboard Air Force One, U.S. President Donald Trump hinted at an aggressive, imminent military campaign, asserting that Washington may have to do “clean-up work” in Iran.

This hawkish rhetoric sent shockwaves through global energy markets, triggering a spike in crude prices with the U.S. benchmark West Texas Intermediate (WTI) briefly breaching the $105-per-barrel threshold. The global benchmark Brent crude surged 3% to settle at $109 per barrel.

On Wall Street, the S&P 500 index, which touched a historic 7,500 threshold on Thursday, retreated to 7,450, while the Nasdaq Composite and Dow Jones Industrial Average were each down by less than 1% Friday afternoon.

Meanwhile, bitcoin’s sharp drop liquidated $86 million in long positions, compared with $11.5 million in short positions. Across the broader cryptocurrency market, nearly $433 million in leveraged positions were wiped out, with longs accounting for $382 million.
