Asian shares hit a record peak on Wednesday as world stocks edged closer to recent highs again, with investors betting on a strong economic recovery next year.
The upbeat mood pushed the safe-haven dollar to its lowest since April 2018 as MSCI's gauge of Asia-Pacific shares, excluding Japan, rose 1.4% to a record high, led by gains in Chinese shares and bringing its gains this year to 19%.
Japan's Nikkei share average lost 0.45%, however, on its last trading day of 2020 after jumping to a 30-year high on Tuesday.
The Australian dollar rose 0.6% to $0.7663, a two-and-a-half-year high. Sterling traded up 0.34% at $1.355. The Japanese yen also gained 0.25% to 103.28 per dollar.
Europe's main markets were hoping for a sixth straight session of gains as AstraZeneca and Oxford University's coronavirus vaccine became the second to be approved by Britain, helping the FTSE 100 add as much as 0.2% early on.
A new, more transmittable variant of the virus is spreading rapidly but European Union countries also began rolling out Pfizer and BioNTech's vaccine this week.
Wall Street was set to open higher, too, with S&P 500 futures up 0.4%. US stocks had retreated from an intraday record high on Tuesday after Senate Majority Leader Mitch McConnell had put off a vote on President Donald Trump's call to increase Covid-19 relief checks.
The United States also detected its first-known case of the new, highly infectious coronavirus strains already spotted in Britain and South Africa.
MSCI’s world stocks index remained upbeat, however, up 0.2% and within touching distance of the record highs it had set on Tuesday.
The index is up 14% this year and nearly 70% from its March lows, boosted by trillions of dollars in global economic stimulus and hopes that coronavirus vaccines will re-open locked-down economies.
"The prospect of more rapid and widespread inoculation will be a shot of confidence to markets as the Covid-19 struggle intensifies," said Janet Mui, investment director at wealth manager Brewin Dolphin.
Away from the virus worries, British lawmakers were set to vote on the UK-European Union trade deal later on Wednesday, a day before a Brexit transition arrangement expires.
Although many Republican Senators in the United States remain adamantly opposed to increasing relief payments, support is growing among them, including two from Georgia, who are running in crucial races that will determine who will control the Senate.
In currency markets, the dollar's weakness continued. It dropped again on Wednesday, the first day where settlement of trades will be in 2021.
The US dollar index hit its lowest since April 2018 before recovering a little ground. It was last down 0.12%. The euro reached its highest since April 2018 at close to $1.23.
"The start of Covid‑19 immunisation campaigns in several countries as well as additional US fiscal support reduce downside risk to the global economy and bode well for general financial market sentiment," analysts at Commonwealth Bank of Australia said.
