MILAN – World stocks rose on Tuesday and US 10-year Treasury yields held above 3 percent as investors prepared for the Federal Reserve's biggest rate hike since 2000.

In a busy week for central bank meetings, Australia's central bank raised its key rate by a bigger-than-expected 25 basis points on Tuesday, lifting the Aussie dollar as much as 1.3 percent and hitting local shares.

On Thursday, the Bank of England is expected to raise rates for the fourth time in a row.

MSCI's benchmark for global stocks gained 0.1 percent by 0813 GMT as European shares rose after surviving a "flash crash" on Monday caused by a single sell order trade by Citigroup.

The pan-European STOXX 600 equity benchmark was up 0.8 percent, bouncing back from Monday's losses with a tech-led rally on Wall Street and supported by upbeat earnings reports and gains in banking stocks tracking higher bond yields.

"These are small flashes of sunshine in the markets. The broader scenario however is not encouraging," said Enrico Vaccari, head of institutional sales at Consultinvest in Milan.

"Even though there's room for stock markets to rally from oversold levels, in the long term the headwinds are too many, simply because the speed of the Fed's rate hikes will drive equity and especially bond market movements," he added.

In the UK, the FTSE 100 index, which reopened following a long weekend, fell 0.2 percent. In France, BNP rose 4 percent after a sharp increase in trading activities helped the country's biggest lender top earnings growth expectations.

Hong Kong's Hang Seng index was little changed and South Korea's KOSPI declined 0.3 percent. Australia's S&P/ASX 200 index fell 0.4 percent as the central bank raised rates and flagged more hikes ahead to contain inflation.

US equity futures rose, with both the Nasdaq and S&P 500 e-minis up around 0.4 percent.

On Monday, Wall Street closed a seesaw session higher as investors bought into tech stocks in the last hour of trading amid bets they had been overly beaten down ahead of this week's Fed meeting.

Investors expect the Fed to raise rates by 50 basis points at the end of a two-day meeting on Wednesday, although there was uncertainty around how hawkish Chair Jerome Powell will sound in comments following the decision.

Around 250 basis points of rate hikes by the end of this year are already priced in by money markets, which some analysts say reduces the scope for hawkish surprises this week.

US treasury yields stayed above 3 percent in European morning trade, after breaching that key psychological milestone for the first time since December 2018 on Monday.

The US benchmark 10-year yield added 2 basis points to 3.0025 percent.

Consultinvest's Vaccari said if 10-year US yields were to reach 4 percent, there would be a "very strong shift towards bonds even though that risk today looks quite far away".

The dollar, which has been supported by safe haven buying on worries over the economic outlook, stayed just below the nearly two-decade high reached in April and the euro steadied above the lowest level in more five than years hit last month.

The dollar index was last at 103.44, down 0.1 percent on the day. The euro traded up 0.1 percent at $1.0536 .

Elsewhere in currency markets, the Australian dollar jumped after the central bank raised its cash rate by a surprisingly large 25 basis points to 0.35 percent, the first hike in more than a decade. It also flagged more rate hikes to come as it pulls down the curtain on massive pandemic-related stimulus.

"The RBA has joined the club, with a rate hike today that was a little larger than we had expected. The case to start to move policy off emergency settings was clear and the RBA has responded to that," said Jo Masters, chief economist at Barrenjoey in Sydney.

The Aussie was up 0.8 percent at $0.7107 as a majority of analysts in a Reuters poll had expected a rise to only 0.25 percent.

The UK pound rose, moving away from its 22-month lows against the dollar as traders took profits on the recent surge in the greenback ahead of the Bank of England policy meeting.

Sterling rose 0.5 percent to $1.254 , against the low of $1.2412 hit last week.

Oil prices slipped, pulled in opposite directions by prospects for a supply hit from a possible European oil embargo on Russia.

Brent crude fell 0.5 percent to $107 per barrel, and US crude also lost 0.5 percent to $104.6.

London copper prices fell to three-month lows as the prospect of aggressive US rate hikes fuelled worries about weaker global growth hitting metals demand.

Benchmark three-month copper on the London Metal Exchange was down 1.7 percent at $9,608.50 a tonne.

Gold prices hit their lowest since mid-February, as an elevated dollar and the imminent rate hike by the Fed dampened bullion's appeal as an inflation hedge.

Spot gold was down 0.4 percent at $1,854.4 per ounce.
