A rally on Wall Street fuelled by hopes for the US economy in the wake of forecast-beating manufacturing data provided investors a much-needed catalyst to jump back in the saddle.

Healthy gains chalked up through January appeared to be in danger at the start of the week as the dollar soared on news that Donald Trump had tapped Kevin Warsh -- considered the most hawkish of his candidates -- to head the Federal Reserve.

Analysts said the choice of Warsh, a former Fed governor and Morgan Stanley investment banker, raised the prospect that central bank policy could be more supportive of the greenback.

The US currency had been taking a battering from its peers last week on concerns that the US president was happy to see it weaken, which would support exporters. Trump's choice also eased concerns about the Fed's independence.

The dollar's sharp recovery sent precious metals plunging at an eye-watering pace, with gold hitting a low of $4,402 and silver $71 -- having enjoyed equally blistering gains in recent weeks to record highs above $5,595 and $121.

The rush out of the safe-haven metals was also driven by easing US-Iran tensions after Trump voiced optimism over a deal with Tehran, having warned of possible strikes on the Islamic republic. That, combined with the stronger dollar, also sent oil prices plunging at breakneck speed.

However, some calm returned to markets Tuesday following a rally in New York, which came thanks to figures showing US manufacturing activity grew in January at its fastest pace since 2022. It also marked the first expansion in 12 months.

Among equity markets, Seoul was the best performer, piling on more than five percent, having dropped a similar amount Monday. The tech-rich index has climbed around 20 percent this year on a rush into all things AI.

Monday's "decline wasn't about the fundamentals of the AI and semiconductor sectors. It happened because liquidity?sensitive assets such as gold and silver plunged sharply", wrote Chung Hae-chang, analyst at Daishin Securities.

"When margin calls occur on one side, investors often adjust collateral, which can trigger movements in other assets as well. (Tuesday's) rebound appears to be a retracement of that move."

Tokyo, which is also home to big-name tech firms, also enjoyed a bounce, adding more than three percent, while Hong Kong, Shanghai, Sydney, Singapore, Taipei, Bangkok and Manila also advanced.

Mumbai's Nifty index soared almost five percent as investors welcomed Trump's announcement of a US-India trade deal. He also pledged to cut tariffs on the country's goods after after Prime Minister Narendra Modi promised to stop buying Russian oil over the war in Ukraine.

"It's been a more orderly and calmer affair across markets, with growing signs that traders are ready to re-engage with pro-risk positions and sell equity index volatility," said Pepperstone's Chris Weston.

"Silver and gold remain somewhat of a Wild West. After such a powerful sell-off, there are scars and war wounds that need time to heal before the market can be confident that positioning has fully unwound and liquidations have run their course."

Traders are keeping tabs on Washington after Trump urged the House of Representatives to swiftly adopt a spending bill and end the three-day government shutdown.

"I hope all Republicans and Democrats will join me in supporting this Bill, and send it to my desk WITHOUT DELAY," Trump said in a post on Truth Social.

The shutdown followed a breakdown in negotiations because of Democratic anger over the killing of two protesters in Minneapolis by federal immigration agents, which derailed talks over new money for the Department of Homeland Security.

Mike Johnson, speaker of the Republican-controlled House, has expressed optimism that an agreement is imminent.
