Asian stocks rose on Tuesday while gold and the Nasdaq were basking in their sharpest gains for months, thanks to signs a deal to end the US government shutdown was in the offing.

In Hong Kong, the benchmark Hang Seng Index gained 99 points, or 0.37 percent, to open at 26,748.

Up north, the benchmark Shanghai Composite Index was up 0.13 percent to 4,023 while the Shenzhen Component Index was 0.36 percent higher at 13,476 and the ChiNext Index, tracking China's Nasdaq-style board of growth enterprises, was up 0.58 percent at 3,197.

Gold jumped nearly 3 percent overnight and was comfortably above US$4,100 in the morning in Asia. The Nasdaq rose 2.3 percent to recover much of the losses inflicted last week by a bout of nerves around the valuation and profitability of AI firms.

South Korea's Kospi was also clawing back last week's falls and advanced 2.1 percent in early trade, while Japan's Nikkei rose 0.7 percent.

S&P 500 futures tacked on 0.1 percent.

A deal that would restore US federal funding and end the longest shutdown on record cleared the Senate on Monday.

The 41-day shutdown could last a few more days as members of the House of Representatives, which has been on recess since mid-September, return to Washington to vote on the legislation.

Prediction markets, such as the online Polymarket, have reopening nearly fully priced in for the end of the week, so the timeline is tight and markets' gains may be vulnerable to delays.

"Markets have reacted positively with a sigh of relief, but it may be too early to pop the champagne," said Vasu Menon, managing director for investment strategy at OCBC in Singapore.

He said the government reopening will lead to the resumption of data publication, which may clear the way to interest rate cuts and is providing extra support for gold prices. (Agencies)
