what happened

Asian equities rose on Wednesday as investors grew more comfortable with major AI companies ahead of the earnings season, Dow Jones Newswires reported. Ashwin Clarke of Commonwealth Bank of Australia said a revival of AI enthusiasm also lifted U.S. stocks on Tuesday.

South Korea's SK Hynix reported that third-quarter net profit tripled and said it would return $75 billion to shareholders. Its shares climbed 9.1%, helping the Kospi gain 5.8%. Together, SK Hynix and Samsung Electronics account for over half of the index's weight.

Japan's Nikkei rose 1.4%, Taiwan's Taiex added 1.6%, and Hong Kong's Hang Seng gained 0.1%. Government bond yields broadly rose ahead of the Federal Reserve's October policy statement; the 30-year Treasury yield climbed 3.0 basis points to 5.3350%. Brent gained 1.75% to $115.87 a barrel as Saudi Arabia said it had contained a fire near its Ras Tanura export terminal after an attack.

why it matters

The rally in Asian indexes rests heavily on a few large chipmakers, so the Kospi's direction depends on SK Hynix and Samsung. Fed rate expectations and supply risks in oil remain the key drivers for global assets.

market impact

Asian stocks and Kospi: support from SK Hynix results and AI optimism; Brent: upward pressure from supply risks

  • Kospi pressure up — SK Hynix's profit jump and large capital return support the index
  • Brent pressure up — the attack and fire at Ras Tanura add risk to crude supply
  • US Treasuries pressure down — yields rose ahead of the Fed statement, pushing prices lower
