Money Markets

Short-term funding instruments — where banks, corporates and governments borrow for days to a year.

The shelf — 10 instruments

Plain English 5

Building Society Savings ContractSave at a below-market rate now to earn the right to borrow at a below-market rate later. A forward-starting mortgage option, sold as a savings account.
Certificate of DepositA deposit with a term and a rate — the same instrument at the savings branch and on a bank funding desk.
Money Market FundThe mutual fund that pretends to be a bank account — cash parked in the market's overnight instruments.
Savings DepositThe product almost everyone owns and almost nobody analyses: a loan you make to a bank, repayable on demand, at a rate the bank chooses.
Treasury BillGovernment debt measured in weeks: the closest thing in finance to cash that pays interest.

Needs one idea 4

Commercial PaperCorporate IOUs measured in days — how blue-chip companies borrow between bond issues and bank lines.
RepoSell a bond today, buy it back tomorrow: the secured loan that finances the entire bond market.
Securities LendingRenting out shares you already own. The invisible plumbing that makes short selling, market making and settlement work — and quietly earns fund holders a few basis points.
Structured DepositA deposit whose interest depends on a market. Capital protected by the bank, upside capped by the option budget — and the budget is smaller than the brochure suggests.

Market knowledge 1

Trade FinanceA bank stands between two strangers on opposite sides of the world so that neither has to trust the other. The oldest financial product still in daily use.

What moves prices here

  1. Where reserves are, and how scarce — Scarcity pushes the rate up through the corridor
  2. Collateral availability — Scarce collateral makes secured borrowing cheaper, not dearer
  3. Haircuts — They set the maximum leverage of the whole system
  4. Credit appetite between banks — The unsecured-to-secured spread is the stress gauge
  5. Regulatory dates — Balance-sheet reporting distorts prices predictably
  6. Money-fund rules — What funds may hold is a legal fact, not a preference
