Oppenheimer & Co. said it was suspending operations at its London Eurobond subsidiary, Oppenheimer International, after the group’s managing director, Alexis Dogilewski, resigned because of a difference of opinion as to how the unit should be run. The $3.5-trillion Eurobond market, which is centered in London, trades debt securities issued outside the country in whose currency they are denominated. A spokesman for the New York-based investment bank said Oppenheimer hopes to resume operations with a new team of traders. Oppenheimer’s London equity operations are run separately and are not affected, he added.
