SINGAPORE, March 18 (Reuters) - Morgan Stanley has strengthened its convertible bonds business by hiring at least three bankers from Standard Chartered, sources told IFR on Thursday.

Ex-Stanchart Managing Director Janice Dunnett will join Morgan Stanley in mid-April as head of convertible bond products in Asia, three banking sources told IFR, a service of Thomson Reuters.

Ronnie Potel, currently Stanchart's head of equity-linked division, will join Morgan Stanley as head of convertible bond origination for Asia Pacific, the sources added.

The third former Stanchart banker is Dave Sandor, who will join Morgan as a vice president. All three are based in Hong Kong, according to IFR.
