Worried about the economy and new Fed rules on capital, the bank wants to hang onto its money just in case, CFO Daryl Bible told investors as he outlined second-quarter earnings.

The Rhode Island-based bank is bolstering its cash position in the face of worries about office loans, stricter capital requirements for regional lenders and the possibility of economic shock from overseas conflicts.

The $668 billion-asset company sold investment securities and certain mortgages to avoid more stringent liquidity and other federal requirements for larger banks. Yet CEO Andy Cecere says U.S. Bancorp is "not under an asset cap at all."

The "Get My Rate" tool, launched on Sept. 4 in collaboration with SavvyMoney, tells current and prospective members what loan rates they qualify for without adversely affecting their credit scores.

Charge-offs at the Detroit-based lender rose last quarter, as borrowers had a tougher time keeping up with their car payments. But so far, credit quality is staying within expectations, and company executives don't anticipate that the rest of the year will be much worse.

The Tennessee bank said a $72 million charge-off tied to a borrower in bankruptcy shaved 10 cents per share off its earnings. Management downplayed the issue, calling it "idiosyncratic," and emphasized that it was growing its loan portfolio.
