FRANKFURT, Germany (AP) - Deutsche Bank AG says net profit fell 34 percent in the first quarter as slower trading of bonds and foreign exchange weighed on revenues.

FRANKFURT, Germany (AP) Deutsche Bank AG says net profit fell 34 percent in the first quarter as slower trading of bonds and foreign exchange weighed on revenues.

Germany's biggest bank made 1.10 billion euros ($1.52 billion) compared to 1.66 billion euros a year ago. Net revenues fell 11 percent to 8.39 billion euros.

Earnings at the investment banking division fell as the bank saw less demand from clients for trading debt such as bonds. Debt markets have suffered from turbulence in emerging markets and from concerns about the eventual withdrawal of monetary stimulus by the U.S. Federal Reserve and other central banks.

Revenue from foreign exchange trading was significantly lower "due to lower client activity and challenging trading environment."

The bank also took 532 million euros in losses from its non-core unit, where it keeps assets that it intends to sell or wind down. That unit suffered from losses at its special commodities group, which took a 151 million euros hit on U.S. power trading due to a price spike caused by severe winter weather.

Co-CEOS Anshu Jain and Juergen Fitschen on Tuesday called it "a resilient performance" and said the bank was making progress in strengthening its finances. The bank is shedding risky investments in order to strengthen its capital levels to meet new regulatory requirements aimed at strengthening the global and European banking systems.

Still, the bank's core Tier 1 capital ratio, a key measure of financial strength, slipped to 9.5 percent during the quarter from 9.7 percent from the previous quarter. The bank cautioned that its capital level could be volatile as it aims for a 10 percent goal by the end of March 2015.
