Call Money
Call money is short-term wholesale funding repayable on demand or at very short notice, often overnight.
Short-term funding terms for repos, sale-and-repurchase agreements, overnight money, call money, collateral, margining, and liquidity risk.
Repo and collateralized funding covers short-term cash borrowing and cash placement where securities, collateral, maturity, margining, and settlement mechanics matter. These pages focus on how funding trades work in money markets, not on generic investing language.
Use this section when the finance question depends on evidence such as a repo confirmation, sale-and-repurchase agreement, collateral schedule, haircut, margin call, settlement record, or overnight funding rate. Legal, tax, accounting, regulatory, and investment conclusions can depend on the actual contract and jurisdiction, so these articles are educational rather than personalized advice.
| Topic | Use it when the question is about | Evidence to check |
|---|---|---|
| Repo Transaction | A securities-backed cash funding trade | Trade ticket, collateral identifier, repo rate, term, haircut, and unwind price |
| Sale and Repurchase Agreement | The formal contract structure behind a repo | Master agreement, confirmation, governing law, margin terms, and close-out provisions |
| Overnight Money | One-business-day cash borrowing or placement | Rate source, calendar, settlement date, repayment date, and rollover plan |
| Call Money | Funds repayable on demand or at very short notice | Call notice, liquidity source, counterparty limit, and repayment procedure |
Start with Repo Transaction when the question is about market mechanics. Use Sale and Repurchase Agreement when the question turns on contract form, legal evidence, or close-out rights.
Use Overnight Money when the key issue is one-business-day funding. Use Call Money when the funding can be called or repaid on very short notice.
For broader money-market context, step back to Short-Term Funding. For bill, commercial paper, banker acceptance, or discount-market comparisons, use Money Market Instruments and Discount Markets.
Repo and collateralized funding can reduce unsecured credit exposure, but collateral does not remove every risk. A serious review separates Counterparty Risk, collateral value risk, Settlement Risk, margin-call risk, rollover risk, legal enforceability risk, and liquidity risk.
Do not treat short maturity as the same thing as low risk. A one-day trade can still fail if the counterparty, settlement system, collateral valuation, holiday calendar, or funding rollover does not work as expected.
Choose a subsection first. Deeper term pages live inside each subsection, which keeps large topic hubs readable.

A repo transaction is a short-term secured funding trade where securities are sold for cash and later repurchased.
