June 10 (Reuters) - U.S. regional lender Comerica said on Monday it expects pressure on its net interest income (NII) forecast for the second quarter and full-year 2024 due to non-interest bearing balance trends.

It had previously forecast a decline in interest income - the difference between what a bank earns on loans and pays on deposits - of between 1% and 2% for the three months ended June 30 versus the first quarter.

The bank also expects a roughly 11% drop in NII for the full-year 2024 versus 2023 levels.
