JPMorgan chief executive Jamie Dimon said the bank is open to tapping the Federal Reserve’s rainy-day fund, a move that’s likely to lessen the stigma associated with borrowing directly from the central bank.

The nation’s biggest bank will occasionally tap the Fed’s discount window when it makes business sense to do so, Dimon said at JPMorgan’s investor day Tuesday. Banks — scarred from the public beating they took during the financial crisis — have all but abandoned the window in recent years to avoid even a whiff of a government bailout.
