SYDNEY, RAW – Asian shares are wavering amid worries that problems with vaccine rollouts combined with new strains of COVID-19 will delay a global economic recovery that has already been baked into the market’s rich valuations.

MSCI’s broadest index of Asia-Pacific shares outside Japan fell 0.4 per cent early on Monday, following four straight sessions of losses. Japan’s Nikkei bounced 0.4 per cent after shedding almost 2 per cent on Friday.

Futures for the S&P 500 lost another 0.7 per cent in heavy trade, while NASDAQ futures fell 0.9 per cent.

Dealers were also warily awaiting new developments in the headline-grabbing battle between retail investors and funds specialising in shorting stocks.

The jitters in stocks caused only a brief ripple in bonds with Treasury yields actually rising late last week, perhaps a refection of the tidal wave of borrowing underway.

A record $US1.11 trillion of gross Treasury issuance is slated for this quarter, up from $US685 billion the same time last year.

Early Monday, US 10-year yields held at 1.07 per cent and near the recent 10-month top of 1.187 per cent.

The euro idled at $1.2121, well off its recent peak at $1.2349, while the dollar held firm at 104.74 yen.

Gold followed silver higher to $1,853 an ounce but has repeatedly stalled at resistance around $1,875.
