Worries about online retail investors' attack on Wall Street short traders was also causing angst on trading floors, with fears they are being forced to sell some equities to cover their backs while silver rallied as it became the new target of buying.

Still, the new week started on a positive note, with Hong Kong, Seoul and Jakarta all up more than two percent, while Tokyo, Mumbai and Taipei jumped more than one percent.
