Barclays announced on April 28 that its trading business experienced mixed results in the first quarter, with equities outperforming expectations while fixed income fell short. According to Jin10, the bank stated on Tuesday that fixed income trading revenue was £1.7 billion, roughly flat year-on-year, while equities trading revenue rose 16% to £1.1 billion. The investment banking division also exceeded expectations, with first-quarter revenue reaching £754 million. Barclays is the first major UK bank to report first-quarter results, providing investors with a reference on how the industry is coping with increased economic uncertainty due to the Iran conflict. Led by Adeel Khan, the global markets business did not benefit from the trading boom experienced by some U.S. counterparts. Earlier this month, Wall Street banks noted that recent market volatility favored trading businesses, with some sectors achieving record earnings. As part of a plan to return £10 billion to shareholders over three years, Barclays announced a new £500 million share buyback. The bank also disclosed a £200 million impairment in its investment banking division related to a "single client," according to sources familiar with the matter.
