European stocks have opened higher and risk appetite in global markets has increased, but worries about the COVID-19 Delta variant hampering economic growth have persisted as investors weigh up the possible timeline for tapering monetary stimulus.
After concerns about slower growth dragged stocks and oil prices lower last week, they picked up in Asian trading.
The MSCI world equity index, which tracks shares in 50 countries, was up 0.4 per cent at 0803 GMT, recovering after having its biggest weekly fall since June last week. Europe's STOXX 600 was up 0.3 per cent.
Oil prices rose, breaking their seven-day losing streak. Brent crude was up 2.1 per cent and US West Texas Intermediate crude was up 2 per cent, after both marked their biggest week of losses in more than nine months last week as markets braced for weakened fuel demand due to a surge in virus infections.
In currencies, the dollar index was at 92.264, down 0.2 per cent on the day, compared to its nine-month high of 92.734 reached on Friday.
"Following the corrections that we have seen over the last week, it's really a bounceback," said Marco Willner, head of investment strategy at NNIP.
"People are looking at Jackson Hole, people are also looking at Delta variant, so the factors have not changed - it's a technical bounceback."
The spread of the Delta variant has the potential to upset the timing of the US Federal Reserve's plans to taper its bond-buying program.
Dallas Federal Reserve President Robert Kaplan, among the US central bank's most forceful supporters for starting to reduce support for the economy, said on Friday he may need to adjust that view if the Delta variant of the coronavirus slows economic growth materially.
Markets will be paying attention to Fed Chair Jerome Powell's speech at Jackson Hole this week, although investors looking for clear indications about tapering may be disappointed.
"One of the key questions will be when the tapering will start. I think it's not a done deal that Powell will make any comments around this at all this week - he might wait til September, maybe even until November, make a major announcement around this one," said NNIP's Willner.
Activity in Germany's manufacturing and services sectors expanded in August, according to PMI surveys, although the pace of growth fell slightly.
Germany's benchmark 10-year yield was at -0.472 per cent , while the US 10-year yield was at 1.2717 per cent, having lacked direction over the past week.
Expectations that the US Fed will ease its monetary stimulus sooner than the European Central Bank have helped the dollar strengthen against the euro in recent weeks, with the euro touching a nine-month low of $1.1664 on Friday. It was up 0.2 per cent at $1.1724 at 0809 GMT on Monday.
Elsewhere, bitcoin rose above $50,000 during Asian trading hours and was up 1.7 per cent on the day at around $50,154. The cryptocurrency reached an all-time high of 64,895.22 in April, dropped sharply in May, and has been gradually recovering since mid-July.
