Bank of America, the second biggest US bank by assets, has today reported an 18% slide in quarterly profit.
Concerns about a global economic slowdown and uncertainty about the pace of US interest rate increases dampened bond and stock trading at the bank.
Net income attributable to common shareholders fell to $2.22 billion, or 21 cents per share, in the three months ended March 31, from $2.72 billion, or 25 cents per share, a year earlier.
Analysts on average had expected earnings of 20 cents per share, according to Thomson Reuters.
Market volatility stemming from a slide in commodity and oil prices, worries about China's economy and uncertainty about interest rates hit trading activity globally in the quarter, particularly in January and February.
Bank of America, one of the biggest US lenders to the oil and gas industry, said total provisions rose 30% to $997m in the quarter, largely due to potential losses on energy loans.
Overall credit quality remained strong, the bank said, while consumer portfolios continued to improve and commercial portfolios remained stable except in the energy sector.
A report by Barclays estimated that 2.3% of the US bank's total loans were energy-related at the end of December.
Bank of America's non-interest expenses fell 6.4% to $14.82 billion, mainly due to a 28% drop in costs in its legacy assets and servicing unit, home to many bad loans inherited from its 2008 purchase of subprime lender Countrywide Financial.
The bank - which has been slower than its rivals to recover from the financial crisis because of problems linked to Countrywide - has been cutting billions of dollars in costs in its commercial lending, investment banking and wealth management businesses to try to make up for sluggish revenue growth.
While Bank of America has shown some progress, it still has to prove it can generate consistent performance under chief executive Brian Moynihan, who took the helm in 2010.
During his tenure, the bank has paid tens of billions of dollars in fines and settlements related to mortgages that were issued before he became CEO.
Adding to his problems, regulators said yesterday that Bank of America could face stricter regulations and capital requirement limits if it did not correct deficiencies in its plans for a bankruptcy that did not rely on taxpayer money.
