Call Money
Call money is short-term wholesale funding repayable on demand or at very short notice, often overnight.
Call money is short-term wholesale funding that is repayable on demand or at very short notice, often overnight. Banks, primary dealers, brokers, and other eligible money-market participants use call money to cover temporary cash needs, invest surplus funds, or bridge settlement timing.
The exact meaning depends on jurisdiction and market convention. In some markets, “call money” is used for overnight unsecured interbank lending, while “notice money” or “term money” describes slightly longer maturities. In older broker or securities-financing usage, a call loan may also refer to a demand loan against securities collateral.

Key Takeaways
- Call money is repayable on demand or with very short notice, commonly overnight.
- It is usually a wholesale money-market concept, not a normal retail savings or checking-account product.
- The borrower cares about immediate Liquidity Management; the lender cares about short maturity, credit quality, and repayment certainty.
- Call-money rates can move quickly when reserves, payment flows, dealer funding, or market stress change.
- Always check the market rule, participant eligibility, collateral terms, rate source, and settlement calendar before using the term in analysis.
How Call Money Works
| Step | What happens | Evidence to review |
|---|---|---|
| Need identified | A bank or dealer has a short cash gap, or another participant has surplus funds | Cash forecast, liquidity buffer, payment queue, and settlement schedule |
| Counterparty selected | The desk borrows from, or lends to, an eligible money-market participant | Approved counterparty list, credit limit, participant rule, and authorization |
| Rate and tenor agreed | Parties agree on amount, interest rate, repayment trigger, and expected maturity | Trade ticket, broker confirmation, rate screen, and dealing record |
| Funds settle | Cash moves through the agreed payment or clearing system | Cash ledger, payment confirmation, cutoff time, and exception report |
| Loan repaid or rolled | The borrower repays on demand, next day, or at the agreed notice/term date | Maturity ladder, rollover decision, repayment confirmation, and liquidity report |
Simple Example
A bank has a one-day cash shortfall after customer payments and securities settlements. It borrows $25 million in call money at an annualized rate of 5.25% and repays the next business day.
Using a 360-day money-market convention, the one-day interest is:
The example is simplified. Actual treatment can change with weekends, holidays, minimum lot size, broker fees, collateral, central-bank facility rules, and whether the loan is repaid on demand or rolled.
Call Money Vs Nearby Terms
| Term | What it usually means | Main distinction |
|---|---|---|
| Call money | Very short-term wholesale funding repayable on demand or short notice | Emphasizes immediate repayability and money-market usage |
| Overnight Money | Institutional funding borrowed and repaid the next business day | Emphasizes one-day tenor rather than demand repayment |
| Notice money | Short-term money repayable after a stated notice period | Not usually repayable immediately on demand |
| Term money | Money-market borrowing for a fixed short maturity | Fixed maturity rather than callable repayment |
| Federal Funds Rate | U.S. overnight reserve-market rate | A specific U.S. benchmark, not the general call-money label |
| Repo Transaction | Secured funding against securities collateral | Collateralized sale-and-repurchase structure rather than unsecured call money |
Why Call Money Matters
Call money is a small-tenor concept with large operational importance:
- Banks may use it to smooth end-of-day reserve, payment, or settlement positions.
- Primary dealers and brokers may use short-term money-market borrowing to manage inventory funding and client flows.
- Lenders use call money to place cash while keeping maturity exposure short.
- Analysts watch call-money conditions because sudden rate spikes can signal tighter liquidity or reduced willingness to lend.
- Treasury, risk, and operations teams use call-money evidence to test funding resilience, counterparty concentration, and intraday liquidity planning.
How To Evaluate A Call-Money Reference
Before relying on a call-money rate, balance, or market comment, verify:
- Market convention: identify whether the reference means call money, notice money, term money, overnight money, or a broker call loan.
- Jurisdiction: rules for eligible participants, reporting, and settlement differ across markets.
- Security: determine whether the borrowing is unsecured or supported by collateral.
- Rate source: use the confirmation, broker record, market platform, or official publication date rather than a loose quote.
- Repayment trigger: confirm whether the lender can demand repayment immediately, on the next business day, or after notice.
- Calendar: check weekends, public holidays, and settlement cutoffs before calculating interest or liquidity coverage.
Risks And Controls
| Risk | Why it matters | Control to check |
|---|---|---|
| Rollover risk | A borrower may not replace short-term funding when the lender calls funds back | Maturity ladder, backup funding plan, and liquidity stress test |
| Counterparty risk | The borrower may fail to repay or the lender may fail to fund | Credit limit, authorization, exposure monitoring, and default process |
| Rate risk | Call-money rates can reprice sharply when liquidity tightens | Rate trigger, escalation policy, and funding-cost attribution |
| Settlement Risk | Cash movement can fail or arrive after operational cutoffs | Payment route, cutoff time, confirmation, and reconciliation |
| Documentation risk | “Call,” “notice,” and “term” can have different rights | Trade confirmation, master terms, local rulebook, and legal review |
| Liquidity-reporting risk | A demandable liability can behave differently from stable funding | Treasury classification, liquidity coverage treatment, and internal limit |
Common Mistakes
- Treating call money as a retail deposit product because the word “money” sounds generic.
- Assuming every call-money market uses the same participant rules or maturity definitions.
- Confusing a call-money rate with a central-bank policy rate.
- Ignoring whether the borrowing is unsecured or collateralized.
- Calculating one-day interest without checking the day-count convention or holiday calendar.
- Treating a high call-money rate as an investment signal without checking market liquidity, credit risk, and transaction size.
