STANDARD Chartered Bank's former general manager Middle East and South Asia Ian Wilson will become general manager, Hong Kong and China, replacing Tony Nicolle who retires in May. Mr Wilson, now based in Dubai, was chief executive for Hong Kong from 1990 to 1992. He joined the bank in 1961 and has worked in India, Pakistan, Singapore, the United States, South Korea and Malaysia. Mr Nicolle, 59, was appointed Hong Kong Banking Commissioner in May 1987 on secondment from the Bank of England after a banking crisis which prompted an overhaul of territory banking regulations. Weaknesses in the regulatory structure were seen as contributing to the crisis that nearly crippled seven banks. Mr Nicolle joined Standard Chartered on finishing his contract in 1991. His move from the public sector to Standard Chartered caused some controversy in banking circles.
