It seems like if there was a Federal law, it would show up somewhere near 18 USC 930, which covers firearm possession on Federal property.

But there is no mention of banks as Federal property there. My NC CCW permit training course handbook lists banks as off-limits, but lists only a state statute as the reference. The listing proscribing carry on Federal property does not list the Federal (or any) statute. I think the Feds are out of the loop.
