Standard Chartered PLC (STAN.LN) remains interested in listing in Shanghai following its recent flotation in India, although the timing will depend on Chinese authorities, the bank's chief executive said Wednesday.

The bank also said that it could eventually move its base out of London, although no such plans are underway at the moment.

Earlier Wednesday, Chairman John Peace warned that the bank is concerned new regulation and taxes are being introduced differently across the world, and that "U.K. banks could be put at a disadvantage to those elsewhere."

"No doubt the argument for London has weakened," CEO Peter Sands told a news conference.

"[Moving] is something we have to think about," he added.

Sands also said he expected the bank to show the benefit from higher interest rates in some countries in 2011, helping net interest margins that have been squeezed lately.

In line with its peers, Standard Chartered has felt the impact of higher costs of borrowing and lower lending rates in the wake of the financial crisis and economic downturn.

The bank derives more than 90% of its income from emerging markets in Asia, Africa and the Middle East, and already has listings in London, Hong Kong and India, becoming the first international company to get a primary listing there in May.

At the time the bank said it was enthusiastic about doing the equivalent in Shanghai.

China's country's State Council is currently drafting rules and setting up a board that would help process the listing of Chinese Deposit Receipts or A-shares of big overseas companies onto the Shanghai Stock Exchange.

Several other financial institutions, among them HSBC Holdings PLC (HBC) and the London Stock Exchange Group PLC (LSE.LN), are weighing up flotations in the country.
