Stocks fell and headed for their largest weekly drop in nearly two months on Friday, while safe haven assets such as bonds and the yen rallied as a new virus variant added to swirling concerns about future growth and higher US interest rates.

“You shoot first and ask questions later when this sort of news erupts.” Japan’s Nikkei was down 1.7% in early trade and Australian shares fell 0.6%.
MSCI’s broadest index of Asia-Pacific shares outside Japan was down 0.2% for a weekly fall of 1% and world stocks, while still near record highs, headed for a weekly fall of 0.7%, the largest since early October.
Little is known about the new variant.
However scientists told reporters it has “very unusual constellation” of mutations, concerning because they could help it evade the body’s immune response and make it more transmissible.
British authorities think it is the most significant variant to date and worry it could resist vaccines.
