New York Clearing House issued loan certificates to stop bank panic

Before the Federal Reserve existed, no institution in the United States was empowered to lend banks emergency cash during a panic — when depositors lost confidence and ran to withdraw, a bank's only real cash sat locked in reserves and in loans it could not call in fast enough.

Each bank on its own faced an impossible choice: hand out its remaining cash until it ran dry and had to suspend, or call in loans and dump assets into a market where nobody was buying, deepening the very panic threatening it. Gold shipments from Europe, the only reliable source of fresh reserves, took weeks to arrive by ship, and with no central bank six years still away, there was no government lender of last resort to bridge that gap.

Pooled member banks' collateral into loan certificates backed by joint liability, accepted only for interbank settlements, saving scarce cash for depositors.

Certificates were backed by the joint liability of all member banks, making them credible for interbank settlement.

Using certificates for interbank claims kept real cash in vaults for depositor withdrawals.

The certificates bridged the gap until gold shipments arrived, preventing bank suspensions.

Trust companies excluded from the scheme suffered worse runs, showing the importance of mutual guarantee.

When cash is scarce, insiders can create a mutually-guaranteed paper substitute for internal settlements, preserving real cash for external demands.

Every certificate used to settle an interbank claim was a dollar of real cash a bank never had to hand over, freeing its actual reserves for the depositors physically demanding withdrawals. A later Federal Reserve Bank of Cleveland analysis of the disaggregated 1907 issuance data found the large New York national banks requested certificates well beyond their own immediate needs specifically to act as private liquidity providers for the rest of the system while gold imports were still in transit.
