The <strong>Korea Exchange was forced to activate a sidecar<\/strong> to halt program trading for five minutes as the index deepened its losses. Concurrently, the <strong>Korean won declined 1% against the greenback<\/strong>, hitting its lowest valuation since the 2009 financial crisis.<\/p>\n<p>In Japan, the <strong>Nikkei 225 index ended down 1.06% at 66,755.06<\/strong>, while Taiwan\u2019s stock market dropped more than 2% in early trading.

Katayama noted that the <strong>Japan-U.S. agreement allows for decisive currency action<\/strong> if needed, as oil price swings continue to pressure the yen. Meanwhile, <strong>Brazil is reportedly ramping up oil output<\/strong> as Asian nations seek alternatives to Iranian supply.<\/p>\n<h2>U.S. Corporate and Regulatory Developments<\/h2>\n<p>In the technology sector, <strong>Broadcom (<a href=\"\/stock\/AVGO\">AVGO<\/a>)<\/strong> issued an AI outlook that was <em>weaker than investors had hoped<\/em>, though it failed to derail broader optimism for the megacap AI trade. Separately, <strong>Nippon Electric Glass<\/strong> is reportedly looking to supply materials for a <strong>rumored foldable iPhone<\/strong>, signaling potential shifts in the smartphone supply chain.<\/p>\n<p>On the regulatory front, the <strong>FDA has begun a review of mifepristone safety<\/strong>, a process projected to last approximately six months. In politics, <strong>DDHQ projects Xavier Becerra<\/strong> will advance to the November general election in California\u2019s gubernatorial race.
