Bank of America Corp ( BAC ) shares are trading lower by 5.7% to $42.95 Tuesday afternoon as fears surrounding U.S. tariffs on Mexico and Canada added to broader market uncertainty.

What To Know: President Donald Trump's firm stance against further trade negotiations has heightened concerns about economic growth, a key factor affecting the bank's lending and investment operations.

As one of the largest U.S. banks, Bank of America ( BAC ) relies heavily on interest income, which makes up over 50% of its total revenue. With the 10-year Treasury yield dropping to 4.16% Tuesday, the bank faces a potential squeeze on its net interest margin, the spread between lending rates and deposit costs.

Lower yields typically reduce the profitability of new loans, especially in the mortgage and corporate lending segments. Additionally, trade disruptions could weaken business confidence, leading to slower loan demand from commercial clients.

Additionally, a weaker economy may also increase credit risk, potentially forcing Bank of America ( BAC ) to raise loan loss reserves, further pressuring earnings.
