Money Market Instruments

After covering long-term debt (Treasuries, agencies, corporates, munis), we turn to the short-term end of the debt market. Money market instruments are all about liquidity and safety.


What Are Money Market Instruments?

  • Short-term debt securities with maturities of 1 year or less
  • Characterized by high liquidity, low risk, and low return
  • Used by corporations and governments for short-term funding needs
  • Serve as near-cash equivalents for investors seeking safety

Think of it this way: Money market instruments are the "savings accounts" of the securities world. You are not looking for big returns; you are parking cash somewhere safe and liquid until you need it.


Key Money Market Instruments

InstrumentIssuerMaturityKey Feature
Commercial Paper (CP)CorporationsUp to 270 daysUnsecured; exempt from SEC registration if maturity is 270 days or less
Bankers' Acceptance (BA)BanksUp to 180 daysFacilitates international trade; bank guarantees payment
Certificates of Deposit (CDs)BanksVaries (typically 1 month to 5 years)FDIC insured up to $250,000; negotiable CDs trade in the secondary market
Repurchase Agreements (Repos)Dealers/BanksOvernight to 14 daysCollateralized short-term borrowing using government securities

Commercial Paper

  • Unsecured, short-term promissory notes issued by large, creditworthy corporations
  • Used to fund day-to-day operations (payroll, inventory, accounts payable)
  • Typically sold at a discount to face value (like Treasury Bills)
  • Maturities average about 30 days but can extend up to 270 days
  • Exempt from SEC registration under Section 3(a)(3) of the Securities Act of 1933, provided:
    • Maturity does not exceed 270 days
    • Sold to sophisticated (institutional) investors
    • Proceeds are used for current transactions (not long-term investment)

Exam Tip: Gotchas

  • Commercial paper is exempt from SEC registration ONLY if maturity does not exceed 270 days. All three conditions must be met.
  • Commercial paper is UNSECURED (unlike repos, which are collateralized). If the issuer defaults, holders have no collateral to claim.

Bankers' Acceptances

  • A time draft drawn on and guaranteed by a bank
  • Primarily used to facilitate international trade transactions
  • The bank's guarantee makes the instrument highly creditworthy
  • Traded at a discount in the secondary market

Think of it this way: A bankers' acceptance is like a bank-backed IOU for international deals. The buyer's bank promises to pay the seller on a set date, so the seller ships the goods with confidence.

Exam Tip: Gotchas

  • Bankers' acceptances are specifically for international trade, not domestic lending.

Negotiable Certificates of Deposit

  • Large-denomination CDs (typically $100,000 or more) issued by commercial banks
  • Unlike regular CDs, negotiable CDs can be traded in the secondary market
  • FDIC insured up to $250,000 per depositor per institution
  • Pay a fixed interest rate

Exam Tip: Gotchas

  • Negotiable CDs trade in the secondary market; regular CDs do not. The word "negotiable" is the key distinction.
  • FDIC insurance on CDs covers up to $250,000 per depositor per institution, regardless of the CD's face value.

Repurchase Agreements (Repos)

  • A dealer sells government securities to an investor and agrees to buy them back at a slightly higher price
  • Essentially a collateralized short-term loan: the securities serve as collateral
  • The difference between the sell and repurchase price represents the interest
  • Very short maturities, often overnight
  • A reverse repo is the same transaction from the buyer's perspective

Think of it this way: A repo is like pawning your government bonds overnight. You sell them to get cash now, then buy them back tomorrow at a slightly higher price. That price difference is the interest you pay for the short-term loan.

Exam Tip: Gotchas

  • Repos are collateralized (backed by government securities), while commercial paper is unsecured. This is a common comparison on the exam.
  • A reverse repo is the same transaction viewed from the other side: the investor buys securities and agrees to sell them back.
