The Dallas-based company is intentionally shedding certain deposit relationships that don't align with its new business model. Total quarterly deposits fell 12.6% year over year, but they rose 1% after excluding the relationships targeted for reduction, according to the bank.

The top five banks and thrifts have combined total assets of more than $12 trillion as of December 31, 2022.

A study published after last month's crisis finds that banks can guard against rate-driven deposit outflows by keeping more liquid funds available. It also concludes that financial institutions with higher rates of uninsured deposits are more likely to face bank runs.

Elevated interest rates, economic uncertainty and financial sector fragility exposed by recent bank failures threaten to stunt lending activity.

The regional bank started making moves to protect deposits last year, which prevented steeper declines during a volatile first quarter, CEO Tim Spence says.

Although the Columbus, Ohio-based regional emerged from the recent crisis relatively unscathed, management was still taking steps to shore up its balance sheet, including forgoing stock buybacks to strengthen a key capital metric.

The Cleveland-based regional bank said that its net interest income fell 10% — and profits declined by an even larger percentage — as it paid more to retain depositors. Still, CEO Chris Gorman said the company is "well prepared to handle the deposit challenges in front of the market."
