The liquidity trap: earning on reserves without locking them up

A mission holds six months of operating reserves — prudent, and often required by its own board policy. But the traditional ways to earn something on that money, like certificates of deposit or term accounts, come with a catch: they lock the funds up for months, precisely when a field emergency might need them.

That's the liquidity trap. And there's a second, quieter problem: transparency. A bank sets a rate, and then quietly lowers it, and unless someone is watching closely, the yield erodes without anyone deciding it should.

A better test for nonprofit reserves. Rather than chasing the highest headline rate, ask whether the yield is benchmarked to a public rate you can verify. SOFR — the Secured Overnight Financing Rate — is published every business day by the Federal Reserve Bank of New York. When a return tracks a benchmark like that, your finance committee can check what you're earning against what the market actually pays. Nothing is hidden.

This isn't speculation. A benchmarked return on balances held in insured custody is a different thing entirely from taking a market position. The funds aren't being traded. They stay liquid — no lockups, no maturity ladders, no minimum balance standing between you and the field.

Governance still leads. A reserves strategy belongs inside a board-approved policy, with proper documentation. The point isn't to reach for return; it's to stop leaving obvious, verifiable value on the table while keeping every dollar available.

Picture a mission earning a SOFR-benchmarked return on its idle reserves while keeping the full balance ready to deploy the moment a field office needs it. That's the combination most nonprofits are told they can't have.

The takeaway: for a nonprofit, verifiable and liquid beats a slightly higher rate that's either opaque or locked away.
