Asian equity markets declined broadly as rising bond yields created pressure across the region's financial markets. Oil price movements contributed to the selling pressure on government bonds, creating headwinds for risk assets.

South Korea's stock market faced particular strain, with foreign investors pulling approximately $13 billion from the market in a significant selloff. The massive outflows pushed market volatility measures near record highs, highlighting investor concerns about the sustainability of recent gains in technology and artificial intelligence-related stocks.

The elevated bond yields posed a specific threat to South Korea's AI sector rally, as higher borrowing costs typically reduce the appeal of growth stocks that have driven much of the market's recent performance. Korean equities extended their recent slump as investors reassessed valuations in the face of changing interest rate expectations.

Elsewhere in the region, Australia made a significant regulatory move by ordering Chinese investors to divest their stakes in rare earth mining operations. The decision reflects growing concerns about foreign control over critical mineral resources that are essential for technology and defense applications.

Japanese markets also experienced corporate-specific turbulence, with Mizuho Financial Group shares falling 7% after the bank denied reports about a potential shift in its investment strategy regarding Rakuten Bank. The denial failed to prevent significant selling pressure on the major financial institution's stock.
