ICBC¡¯s Shanghai-listed A shares surged 2.68% to 5.75 yuan, giving it a market capitalisation of $254bn, according to Reuters calculations.
That exceeded the $251bn capitalisation of Citigroup, previously the world¡¯s biggest bank, when its shares closed at $50.73 in New York on Friday. HSBC Holdings was in third place with $215bn.
Shares in ICBC, which listed in Shanghai and Hong Kong last October, have gained 15% this month on the back of a rally in China¡¯s booming stock market as well as strong growth in the bank¡¯s own earnings.
Weakness in Citigroup¡¯s share price, and appreciation of the yuan against the dollar have also shifted market values in favour of ICBC.
But some analysts believe ICBC¡¯s ballooning capitalisation may also be a sign of a dangerously overheated Shanghai stock market as speculating Chinese investors pour money into shares.
ICBC, a state-controlled behemoth which is trying to modernise a creaky branch network operating almost entirely inside China, reported income of $24bn last year.
Citigroup, one of the world¡¯s most sophisticated financial institutions with operations around the globe, reported income almost four times as large, at $90bn.
ICBC¡¯s share price yesterday valued it at 28 times analysts¡¯ forecasts for its earnings per share in 2007, far above 11 times for Citigroup and an average of 16 times for major global banks, according to Reuters Estimates. ¨C Reuters
