What it means
Federal deposit insurance protects each depositor at each insured bank up to a limit set by the insurer. A company, charity or local authority holding several million dollars at one bank is therefore uninsured on most of that balance, which is a genuine credit exposure to a single institution rather than a technicality.
The network answers this with reciprocal placement. The depositor's own bank keeps the relationship and places the money as certificates of deposit at other member banks in slices below the insured limit, receiving matching deposits from those banks in return.
The depositor never contacts the receiving banks and still earns one agreed rate across the whole amount. The appeal is administrative as much as financial.
Opening, documenting and monitoring eight or ten separate bank relationships is weeks of work for a small finance team, and the service compresses all of it into one signed agreement and one statement. The costs are a slightly lower rate than the very best directly negotiated deposit rate and the loss of instant access, because certificates of deposit have fixed maturities and penalties for early withdrawal.
A companion arrangement places funds in insured demand deposit accounts instead, which suits money that may be needed at short notice. Two limits matter in practice.
There is a maximum amount one depositor can place through the network, and the insurance only works as intended if the depositor does not already hold balances at the receiving banks, since cover is per depositor per bank and balances at the same bank are added together. For a finance function this is a treasury policy decision rather than a product purchase.
The policy should state whether every dollar must be insured, whether a strong bank's own credit is acceptable, or whether government securities are preferred, and that decision is far easier to make calmly in advance than during a banking scare.
In practice
Real-world examples.
Example
A school district holds $5,000,000 of building reserves that it will not touch for two years. The treasurer places the funds through the network in slices below the insured limit, satisfying a board policy that requires all deposits to be fully insured. One statement replaces the twenty-odd bank confirmations the previous auditor had asked for.
Example
A manufacturing company sells a surplus site for $3,600,000 and expects to reinvest in 18 months. Rather than open new bank relationships, it uses its existing bank to place the proceeds across member banks at a single agreed rate. The finance director records the placement as a short-term investment with staggered maturities.
Example
A medical group practice receives an insurance settlement and must hold the money while a dispute is resolved. Its policy forbids any uninsured bank exposure, so the funds go through the network in insured slices. The practice keeps one point of contact and avoids explaining a dozen new accounts to its auditors.
Formula
Calculation
Number of banks required = Total deposit / Slice size per bank, where the slice size is set below the insured limit to leave room for interest to accrue.
Assume the insured limit is $250,000 per depositor per bank and the slice size is set at $240,000.
A charity holds $2,400,000 of reserves. 2,400,000 / 240,000 = 10 banks, each holding a $240,000 certificate of deposit.
At an annual rate of 3%, one slice grows to 240,000 x 1.03 = $247,200 after a year, which is still below the $250,000 limit, so both principal and interest remain insured. Interest across the whole placement is 2,400,000 x 3% = $72,000.
Had the charity simply left the $2,400,000 on deposit at one bank, only $250,000 would have been insured and $2,150,000 would have been exposed to that single bank failing. The service converts a $2,150,000 credit exposure into an administrative arrangement, and the price is usually a fraction of a percentage point of yield.Case study
Seen in the real world.
Cedar Fen Community Trust is an illustrative, fictional charity used here to show how deposit concentration creeps up without anyone deciding on it. The trust had built $4,200,000 of reserves over 15 years and held all of it at the local bank that had served it since the beginning.
A new treasurer read the deposit insurance rules properly and worked out that roughly $3,950,000 of the reserves were uninsured. In this fictional example the trustees had never been shown that number, and their investment policy said nothing about bank credit at all.
The trust kept its relationship bank and used the registry service to place the reserves in insured slices across 18 member banks, accepting a rate about 0.2 percentage points below the best single-bank offer, which cost roughly $8,400 a year. The illustrative point is that the trustees could finally describe the risk they had chosen, instead of carrying one they had never discussed.
Watch out
Common mistakes.
- Believing deposit insurance covers a whole balance at a bank, when cover applies per depositor per bank up to a stated limit and anything above it ranks as an ordinary claim.
- Setting the slice size exactly at the insurance limit, which leaves accrued interest uninsured as soon as it is credited.
- Treating the placement as instantly accessible cash, when the underlying certificates of deposit have fixed maturities and early withdrawal penalties.
Questions
People also ask.
Does the money leave my own bank?
Legally the deposits sit at other member banks, but the relationship, the paperwork, the single rate and the statement all stay with the bank you chose.
Is it the same thing as buying government securities?
No, it keeps the funds in bank deposits with insurance cover, whereas a government security is a direct claim on the government and can be sold before maturity at whatever the market pays.
What is the main catch?
A slightly lower yield than the sharpest single-bank rate, plus a cap on how much any one depositor can place through the network, which large treasuries can hit.
