Agricultural Bank of China Ltd. increased the range of its initial public presenting around $20.8 billion subsequently to selling more stock in Hong Kong, moving it nearer to making it the leading first-time share sale.

It said in a statement today that China’s biggest lender by customers sold a further 3.81 billion shares at the IPO price of HK$3.20, increasing HK$12.2 billion ($1.57 billion). The IPO elevated $19.2 billion in Hong Kong and Shanghai before the over allotment.

Francis Lun, general manager at Fulbright Securities Ltd said that Chinese banks “are required by regulators to replenish capital probably because of last year’s big push to extend credit to stimulate the economy. Compared to European banks, Chinese lenders are actually very well capitalized.”

Meanwhile in Hong Kong, Agricultural Bank shares dropped as much as 1.4 percent to HK$3.53. Taking today into account, the stock has increased 8.9 percent since its July 16 entrance, while in Shanghai, where the shares began trading one day sooner, it has increased 4.8 percent.

Agricultural Bank is the last major Chinese bank to go public, wrapping up a decade-long overhaul of the nation’s banking industry that cost an estimated $650 billion.

James Liu, a Shanghai-based analyst at Sinopac Financial Holdings Co. claimed that “Chinese banks may start to face some real pressure from rising non-performing loans as early as August and September. Raising capital now may also be a preparation for that.”

Last month, Construction Bank, the world’s second-largest lender by market value, won shareholder approval for a plan to raise as much as 75 billion yuan in a rights offer.

Guotai Junan Securities Co., Citic Securities Co., China Galaxy Securities Co. and CICC are organizing Agricultural Bank’s yuan-denominated A-share offering.
