Most Asian markets rose Monday following a rally on Wall Street and record-breaking day in Europe, with sentiment boosted by positive talks between Donald Trump and Chinese President Xi Jinping that soothed worries about the incoming US leader's second term.

A sense of caution has permeated trading floors ahead of the tycoon's inauguration later in the day after he warned he would impose hefty tariffs on imports, fanning fears of another debilitating trade war between the economic superpowers.

Pledges to slash taxes, regulations and immigration has also led to concerns that inflation could be reignited and force the Federal Reserve to hold off cutting interest rates further, with some observers even flagging possible hikes.

Still, while dealers nervously eye the next four years, there was some relief after news of the phone call on Friday.

Trump and Xi vowed to improve ties between Washington and Beijing, with the Chinese leader hoping for a "good start" to relations and the president-elect saying "it is my expectation that we will solve many problems together".

On his Truth Social media platform, Trump added: "We discussed balancing Trade, Fentanyl, TikTok, and many other subjects.

"President Xi and I will do everything possible to make the World more peaceful and safe!"

Their comments provided some cheer to markets, with the S&P 500 ending up one percent and Nasdaq 1.5 percent. London and Frankfurt had earlier chalked up fresh all-time highs.

"The start of a new presidency often brings fresh energy — and uncertainty to the financial markets," said Saxo Markets chief investment strategist Charu Chanana.

"With Donald Trump's inauguration, investors are bracing for significant policy shifts. This could mean changes in taxes, spending, and trade agreements."

Hong Kong led gains in Asia amid hopes that the feared trade war can be averted, with Tokyo, Shanghai, Sydney, Taipei, Manila and Jakarta also rising. Singapore and Wellington were down.

Seoul edged up but gains were limited after the Bank of Korea cut its 2025 economic growth forecast owing to weakening sentiment and political risks following last month's brief declaration of martial law by President Yoon Suk Yeol and the political crisis it has sparked.

On currency markets the yen edged up against the dollar ahead of the Bank of Japan's policy meeting this week, with expectations that it will hike rates for the third time since March.

Economists at Moody's Analytics said the central bank has "struggled to provide consistent guidance on policy" but that recent hawkish comments from the governor and deputy governor "suggest further tightening is on the horizon".

"The yen has weakened significantly since the BoJ decided to skip a rate hike in December. This, combined with a series of hotter-than-expected inflation prints for consumer, producer and import prices, raises the odds of monetary policy action in January," they added.
