Asia markets trade mixed after U.S. government shuts down

Asia-Pacific markets were mixed Wednesday, following gains on Wall Street as investors appeared unperturbed by the U.S. government shutdown.

Spot gold prices hit a fresh record of $3,875.32 as of 11:04 a.m. Singapore time (11:04 p.m. ET).

Over in Japan, the central bank released the results for its third-quarter Tankan survey. The Tankan survey measures business sentiment among domestic companies, and is closely watched by the Bank of Japan.

The index for business optimism among large Japanese manufacturers increased to +14 for the third quarter from +13 in the previous quarter, but was lower than the +15 expected by economists polled by Reuters. The non-manufacturing index held steady at +34. A positive figure on the Tankan indicates that optimists outnumber pessimists.

Japan's Nikkei 225 sunk 0.85% to close at 44,550.85, marking its fourth straight day of losses, while the broad-based Topix was down 1.37% and ended at 3,094.74.

The Taiwan Weighted Index pared earlier gains to rise 0.63% to 25,982.91. Chip heavyweight TSMC was up 1.53% after AI darling Nvidia topped $4.5 trillion in market cap.

Australia's S&P/ASX 200 slipped marginally to close at 8,845.7.

Markets on mainland China and Hong Kong were closed for a holiday.

Overnight in the U.S., the S&P 500 closed up 0.41% at 6,688.46, while the Nasdaq Composite climbed 0.31% to finish at 22,660.01.

The Dow Jones Industrial Average advanced 81.82 points, or 0.18%, to close at 46,397.89 — a fresh closing high.
