LONDON – World stocks paused near five-month highs on Wednesday, as signs that central banks might need to keep hiking interest rates for longer dampened a recent wave of optimism that aggressive monetary tightening among big central banks is almost done.

Australia's dollar shot up over 0.7 percent to its highest in over five months after data showing inflation rose to a 33-year high of 7.8 percent last quarter bolstered the case for another interest-rate hike from the Reserve Bank of Australia (RBA) next month.

Canada's central bank is widely expected to lift interest rates again later on Wednesday, with recent strong data supporting expectations for another move.

Trade in European stocks was lacklustre and the broad Euro STOXX 600 slipped 0.3 percent. US stock futures pointed to a soft open for Wall Street.

Globally, stocks have posted strong gains this year after a rout in 2022, on expectations that inflation has peaked and that US interest rate rises will taper off. 

MSCI's world equity index, up more than 6 percent this month, was broadly steady near five-month highs on Wednesday.

"Our view is that the move in risk assets is overdone," said Guy Miller, chief market strategist at Zurich Insurance Group.

"Broadly speaking, the problem that we have is that economic conditions are getting worse and the data we are looking at points in that direction."

In Asia, MSCI's broadest index of Asia-Pacific shares outside Japan hit a seven-month high. 

Shares in Microsoft gave up most of their 4 percent gains posted in after-hours trade. The tech titan's better-than-expected results showed some strength in the face of a weak economy but weak revenue growth signaled tougher times for the sector.

Microsoft on Wednesday said it was investigating a networking issue that impacted multiple services.

Australian dollar surge

In currency markets, the Australian dollar surged to $0.7123 after the latest inflation data. Australia's currency has risen almost 2 percent this week and is poised for its biggest weekly jump in over two months.

Investors sharply narrowed the odds on the RBA lifting its cash rate by a quarter point to 3.35 percent when it meets on Feb 7. Previously, some analysts had thought there was a chance the RBA might pause its tightening campaign.

"The RBA is hiking the cash rate by 25 basis points a meeting, and we do not believe this will change," ING analysts said in a note.

The euro was flat at around $1.0887 and holding below recent nine-month peaks.

Data showing German business morale brightened in January didn't appear to be reason enough to push the single currency higher for now.

Germany's Ifo institute said its business climate index rose to 90.2, in line with consensus according to a Reuters poll of analysts and up from 88.6 in December.

The New Zealand dollar fell after New Zealand reported annual inflation of 7.2 percent in the fourth quarter, below a central bank forecast of 7.5 percent.

Oil prices edged higher, with Brent crude futures last up 0.4 percent at $86.46 a barrel after declining 2.3 percent in the previous session. West Texas Intermediate (WTI) US crude rallied 0.3 percent to $80.36, after a 1.8 percent drop on Tuesday.

Gold prices dipped 0.5 percent to $1,928 per ounce, off a nine-month peak touched in the previous session.
