Bitcoin Rally Stalls Below $84,000 as Dollar Strength and Bond Volatility Weigh

Bitcoin's attempt to break decisively above the $84,000 level fizzled again on Tuesday, as a strengthening U.S. dollar and rising volatility in the Treasury market combined to cap risk appetite across global assets.

The largest cryptocurrency traded near $83,800 during U.S. hours after briefly approaching $84,000 at the start of the Wall Street session, according to TradingView data. The price action unfolded against a backdrop of renewed turbulence in South Korean equities, where the KOSPI Composite Index extended a two-day slump that totaled 7.4%.

Semiconductor stocks led the decline in Seoul, pressured by concerns over whether the aggressive pace of artificial intelligence capital spending can be sustained and by the competitive threat posed by Chinese chipmakers. The selloff rippled through Asian trading, dragging U.S. equity futures lower before American markets opened.

Yet the damage in U.S. stocks proved limited. Both the S&P 500 and the Nasdaq Composite turned briefly positive after opening in the red, and by early afternoon each index was down less than 0.5%. The resilience suggested investors were distinguishing between Korea-specific pressures and the broader global outlook, even as macro headwinds continued to build.
