HVB Asia's Nick Hamilton, managing director and head of securitization and credit trading in Singapore, has been appointed ceo for Asia, following the retirement of Walter Fuchs, who was based in Hong Kong, according to officials close to the firm. "He's built up their securitization business into a very profitable niche group," said a market official, commenting on the firm's moneymaking cross-border securitization and synthetic CDO presence in the region. As ceo, Hamilton now has responsibility over all sales and trading for Asia. He was traveling and could not be reached.
