Investors weighing the prospects of a September cut had been closely eyeing the speech by Federal Reserve Chair Jerome Powell at an annual symposium in Jackson Hole, Wyoming.

"The balance of risks appears to be shifting," Powell said, noting a slump in employment even as inflation remains above target.

He added that the "unusual" situation "may warrant adjusting our policy stance".

Wall Street stocks surged following Powell's speech, rebounding from a tech sell-off earlier in the week. European markets also ticked upwards.

During the first trading sessions in major Asian markets following the comments, stocks made notable gains.

Hong Kong's main index was up nearly 1.3 percent one hour after opening, while benchmarks in Tokyo, Shanghai, Sydney, Seoul and Taipei also rose.

"By hinting that the Fed could cut even without pristine inflation numbers, (Powell) transformed caution into conviction," Stephen Innes of SPI Asset Management wrote in a note Monday.

"Expectations for a September cut now hover near certainty," he added.

Powell has come under intense public pressure this year from US President Donald Trump to lower rates.

But the independent central bank has kept benchmark interest rates steady at a range of between 4.25 percent and 4.50 percent since its last reduction in December.

In keeping rates unchanged, policymakers cited resilience in the labor market as they monitored the effects of Trump's wide-ranging tariffs on the world's biggest economy.

Reacting to Friday's news, the dollar fell against currencies such as the euro, pound and yen, as lower returns make the greenback less appealing to foreign investors.

Oil markets were nearly flat Monday, following price increases made last week as investors considered the potential for a peace deal in Ukraine more than three years after Russia's invasion.

Traders are now eagerly awaiting a quarterly earnings report from US chip juggernaut Nvidia on Wednesday, which is expected to shed light on how its strong push into artificial intelligence is faring.
