But as those sources indicated, the Chase policy and the “Updated Safe Deposit Box Lease Agreements” started April 2015. If you haven't signed/renewed a Chase lease since then you will not be hit till you do.
So either read closely your next Chase lease renewal or reread any Chase renewal you have signed since April and you will see the following (excerpted exactly) from an actual Chase Safe Deposit Box Lease Agreement I've seen and copied:
"You agree not to use the box to store money, coin or currency unless it is of a collectable nature."And if anyone wants to argue that they can win against Chase & the Fed (with both their armies of lawyers) by claiming their signed agreement not to store cash does not mean cash was prohibited by the terms of their lease - don't bother replying to me. I don't respond to calls from never-never-land."You agree that we may turn over to any law enforcement or governmental agency any object of yours, which we believe, in our sole discretion, to be prohibited by the terms of the lease."
