Stock markets rose strongly Tuesday as a key measure of US inflation slowed more than expected, raising hopes the Federal Reserve is done raising rates for the moment.

The US consumer price index (CPI) increased by 3.2 percent in the 12 months to October, down from 3.7 percent a month earlier, the Labor Department said in a statement.

Analysts had been expecting an increase of about 3.3 percent.

The moderating outlook for inflation sent both bond yields and the dollar lower, with the greenback now at its weakest level against the euro in two months. 

The "market now says 'no more hikes'," said Neil Wilson, chief market analyst at Markets.com. "This may be premature, but the market has moved sharply to say that the Fed is now done."

While down sharply since the start of the year, annual inflation remains well above the Fed's two-percent target.  

The Federal Reserve recently held its key lending rate at a 22-year high for a second consecutive meeting, leading some analysts and traders to predict it was done tightening monetary policy in order to avoid tipping the economy into recession. 

But since then, a number of policymakers, including Fed Chair Jerome Powell, have indicated that they are prepared to hike rates again, if necessary, to bring price increases firmly down to target.

A number of upcoming speeches by Fed decision-makers will now be pored over in light of the latest inflation numbers.   

"The softer CPI inflation data mean the market will have a harder time absorbing hawkish rhetoric from the Fed," said Jane Foley, head of foreign exchange strategy at Rabobank in London. 

"Without further upside shocks to inflation, policymakers will have a hard time steering the market away from talk of rate cuts in 2024." 

London stocks lagged increases elsewhere as official data showed UK wages rose faster than inflation, reigniting concerns that British interest rates could remain at multi-year highs for longer than thought, or even increase further.

Official data, however, is expected to reveal on Wednesday a sharp fall in British annual inflation.

Meanwhile, there are hopes that this week's upcoming meeting between US President Joe Biden and Chinese leader Xi Jinping could ease tensions between the economic superpowers, further comforting the markets.
