Buy Shares said banks went into the pandemic stronger and it might take time before they return to normal profitability.
"The pandemic led to a slump in various sectors of the economy and it was evident under the stock markets. The crisis generated massive instability and high volatility in global capital markets," it said.
"The financial sector was among the most impacted leading to the drop in market capitalisation."
Many Chinese institutions made the list including, the Industrial & Commercial Bank of China (-27.65), China Construction Bank (-18.95) and the Agricultural Bank of China (-23.31%).
Japanese banks also made a heavy presence with the Japan Post Bank (-19.18%), Mizuho Financial Group (-11.33%) and Sumitomo Mitsui Financial Group (-20.59%).
