Equities surged Wednesday and the dollar struggled after slower-than-forecast US inflation was seen as all but putting to bed any chance of another interest rate hike, even allowing traders to bet on a series of cuts in the new year.

A big slowdown in UK prices gave traders extra support, but weighed on sterling.

Investors built on a strong performance on Wall Street -- where US Treasury yields also sank -- fuelled by a sense of relief sweeping through markets that more than a year of painful tightening may have finally come to an end.

The 3.3 percent reading in the October consumer price index was well down from the 3.7 percent seen in the previous month and 0.1 percentage point below what was expected. Core inflation was also below estimates.

Several Fed officials have lined up in recent months to warn that while inflation has come down from the multi-decade peaks of last year, it remained too high to give up on their rate-hike campaign for fear of prices reflating.

But the latest figures will embolden traders, who are sceptical that the central bank will act on any hawkish instincts for fear of tipping the economy into recession.

Data suggests they are now betting on as much as a one percentage point cut in rates through next year.

"The fact that the US Fed seems to be done with rates and inflation is behind us for now is definitely a positive for all risky assets," Pooja Malik, of Nipun Capital, told Bloomberg Television, but she warned of the possibility of more volatility over the next 12-18 months.

After Wall Street's rally that saw the Nasdaq jump more than two percent and the S&P 1.9 percent, Asia picked up the baton.

Tech giants helped push Hong Kong nearly four percent higher, while Tokyo, Seoul and Bangkok each added more than two percent.

Sydney, Wellington, Mumbai, Taipei and Jakarta were all up more than one percent, with Shanghai, Singapore and Manila also in positive territory. Paris and Frankfurt both rose at the open.

London extended Tuesday's rally after data showed UK inflation slowed sharply in October. The CPI hit 4.6 percent, well down from 6.7 percent in September and also slightly better than expectations.

The pound weakened against the dollar, paring the gains enjoyed after the US inflation reading.

Still, the figures will ease the country's cost-of-living crisis and give under-fire Prime Minister Rishi Sunak something to cheer about after a torrid few days that have seen him come under pressure from within his party after firing his rightwing Home Secretary Suella Braverman.

The dollar remained under pressure agains most other units, having dropped against its major peers, though the yen's rally was tempered by news that Japan's economy shrank more than forecast in the third quarter.

The greenback was down two percent against the South Korean won, Australian dollar and South African rand, while it was also well off versus the Mexican peso, Canadian dollar, Thai baht and Chinese yuan.

"The last of investors not convinced the Fed is done are likely 'throwing in the towel'," Bryce Doty, of Sit Fixed Income Advisors, said.

Still, Fed officials remain cautious, with Chicago boss Austan Goolsbee saying that "progress continues, though we still have a way to go".

He added: "There are always some bumps in the road as inflation comes down."

But he was increasingly hopeful the economy could be on track for a soft landing, where inflation is brought to heel and the economy remains healthy.

Richmond chief Thomas Barkin was "just not convinced that inflation is on some smooth glide path down to two percent", which is the bank's target.

Jamie Dimon, the head of JPMorgan Chase, added that while the figures were good, he thought inflation was a little more sticky than they showed.

"I still think you should prepare (for the fact the Fed) may need to do a little bit more," he told Bloomberg.
