Stock markets rose across Asia and Europe, but London was the clear winner, as investors also assessed the outlook for US borrowing costs.
"European markets are enjoying a positive start to the day, led by the FTSE 100, which has been in buoyant mood following a welcome decline in UK inflation," noted Joshua Mahony, chief market analyst at traders Scope Markets.
London's benchmark stock index jumped 1.7 percent in late morning deals, while Paris flattened and Frankfurt edged up.
Britain's annual inflation rate slowed to 3.2 percent in November, cementing expectations that the Bank of England will cut its main interest rate on Thursday and again on more than one occasion in 2026.
Analysts had expected inflation to have cooled only slightly to 3.5 percent from 3.6 percent in October.
Eurozone inflation remained at 2.1 percent in November, hovering just above the target set by the European Central Bank, slightly revised official data showed Wednesday.
The ECB is expected to hold interest rates steady on Thursday for its fourth straight meeting with inflation in check, although debate is heating up about the path forward.
Elsewhere on Wednesday, oil prices rebounded after US President Donald Trump ordered the blockade of "sanctioned" Venezuelan tankers.
The gains pared some of the 2.7 percent in losses suffered Tuesday after the US president said a deal to end the war in Ukraine was closer than ever.
Such a move could ease sanctions on Russian oil, adding to oversupply concerns already weighing on the market.
Investors continued to study Tuesday's release of the US non-farm payrolls reports, which showed that unemployment in the world's biggest economy had jumped to a four-year high of 4.6 percent in November.
Analysts said the data did little to change expectations that the Federal Reserve would likely keep key US interest rates unchanged in January.
Wall Street investors on Tuesday largely shrugged at the jobs data, with many concerned that the tech-led stocks rally over the past two years may have gone too far and that the vast sums invested in artificial intelligence might not see returns as soon as hoped.
In corporate news, the share price of Chinese chipmaker MetaX Integrated Circuits Shanghai soared more than 550 percent on its home city debut on Wednesday.
