Morgan Stanley said it has acquired China's Nan Tung Bank, a deal that would give the Wall Street giant a coveted onshore commercial banking licence in China ahead of US investment bank rivals.
The deal, approved by the China Banking Regulatory Commission, allows Morgan Stanley to apply immediately to offer yuan-denominated products.
It will also enable the US bank to strengthen its Chinese operation and offer a broader range of products and services.
Morgan Stanley did not disclose what it paid for the Zhuhai-based foreign-funded bank formerly owned by Bank of China subsidiary Nam Tung (Macao) Investment.
The bank has a single branch with fewer than 40 employees and is currently only allowed to deal in foreign currencies, including US and Hong Kong dollars.
Major international investment banks are scrambling to get a foothold in China to take advantage of the country's fast-growing and potentially lucrative financial sector.
"We want to build the leading, fully integrated financial services firm in China and the acquisition of Nan Tung Bank is another important milestone in our pursuit of that strategy," John Mack, Morgan Stanley's chairman and chief executive, said in a statement.
Morgan Stanley has long had a leg up on most of its US rivals in the Chinese market thanks to its 35 per cent stake in investment bank China International Capital Corp, acquired in 1995.
The stake gave Morgan Stanley the sole China joint venture among Wall Street banks.
"We are pleased to be the first among our peers to establish an onshore commercial banking platform in China.
"We believe it will help further strengthen our leadership position in this increasingly important market."
Since rejoining Morgan Stanley in June 2005, Mack has made expansion in emerging markets one of his top priorities, highlighting opportunities in Brazil, India and Russia, as well as China.
Morgan Stanley's traditional US investment banking rivals including Goldman Sachs, Merrill Lynch and Lehman Brothers do not have licences for commercial banking in China.
But several other international financial firms do, including Switzerland's Credit Suisse and France's Societe Generale.
Nan Tung Bank currently offers commercial banking products and services in foreign currencies to individual and corporate customers based primarily in the Pearl River Delta region of Guangdong Province.
These include deposits, home mortgage loans, corporate loans, foreign currency exchange and remittances, trade finance and credit facilities.
Morgan Stanley said it planned to use its "global strength, industry expertise and multi-product capabilities" to grow the business and help develop China's indigenous financial sector.
