The Financial Post reports in its Thursday edition that Bank of America's traders posted a record second quarter as the company reaped the benefits of volatile markets and net interest income topped analysts' estimates. A Bloomberg dispatch to the Post says that revenue from fixed income, currencies and commodities trading jumped 19 per cent to $3.25-billion in the three months through June (all figures U.S.). That helped Bank of America top analysts' estimates for per-share earnings. Equity trading rose 9.6 per cent to $2.13-billion. Volatility has whipsawed global markets since President Donald Trump announced tariffs on trading partners around the world in April. That has been good news for the markets businesses at Bank of America and its rivals across Wall Street as they have benefited from a surge in client activity while also thwarting expectations for a strong rebound in mergers and acquisitions. The second-largest U.S. bank also said that net interest income, a key source of revenue for the company, rose 7.1 per cent to $14.7-billion. Over all, BofA, based in Charlotte, N.C., saw its second-quarter profit rose, with net income up 3.2 per cent to $7.12-billion, more than the $6.56-billion analysts had predicted.
