Money market instruments are short-term, highly liquid debt securities used by governments, corporations, and financial institutions to manage short-term funding needs. These instruments are considered low-risk and are essential to understanding the fixed-income markets tested on the SIE exam.

What Is the Money Market?

The money market is where short-term debt instruments are traded. Key characteristics:

  • Maturity: One year or less
  • Liquidity: Very high—can be quickly converted to cash
  • Safety: Generally low-risk
  • Purpose: Short-term borrowing and lending

Types of Money Market Instruments

Treasury Bills (T-Bills)

T-Bills are short-term government securities and the benchmark for money market rates.

FeatureDetail
IssuerU.S. Treasury
Maturities4, 8, 13, 26, 52 weeks
InterestNone—sold at discount
Minimum$100
RiskVirtually risk-free
TaxFederal only (exempt from state/local)

Most Liquid: T-Bills are considered the most liquid and safest of all money market instruments.

Commercial Paper

Commercial paper is unsecured, short-term corporate debt issued by large, creditworthy corporations.

FeatureDetail
IssuerCorporations with strong credit
Maximum maturity270 days
InterestSold at discount
RegistrationExempt from SEC if ≤270 days
RiskLow but higher than T-bills

Why 270 Days? If maturity exceeds 270 days, the issuer must register with the SEC, which is costly and time-consuming.

Key Points:

  • Used for short-term working capital needs
  • Only issued by companies with excellent credit ratings
  • Not backed by collateral (unsecured)

Banker's Acceptances (BAs)

Banker's acceptances are time drafts "accepted" (guaranteed) by a bank, primarily used in international trade.

FeatureDetail
IssuerCreated by corporations, guaranteed by banks
Maturities30-180 days
InterestSold at discount
Primary useInternational trade financing
RiskLow (bank guarantee)

How BAs Work:

  1. Importer's bank "accepts" responsibility to pay
  2. The BA becomes a negotiable instrument
  3. Can be sold in secondary market before maturity

Example: A U.S. company imports goods from Japan. A bank issues a BA promising to pay the Japanese exporter in 90 days. The exporter can sell the BA at a discount for immediate cash.

Negotiable Certificates of Deposit (CDs)

Negotiable CDs are large-denomination bank deposits that can be traded in the secondary market.

FeatureDetail
IssuerCommercial banks
Minimum$100,000 (typically $1 million+)
Maturities2 weeks to 1 year
InterestPays interest at maturity
TradingTrades with accrued interest

Negotiable vs. Regular CDs: Unlike retail CDs from your local bank, negotiable CDs can be bought and sold in the secondary market before maturity.

Repurchase Agreements (Repos)

Repos are short-term loans collateralized by securities, typically Treasury securities.

FeatureDetail
StructureSell securities + agree to repurchase
CollateralUsually Treasury securities
MaturitiesOvernight to 30 days
UsersBanks, dealers, Federal Reserve
RiskVery low (collateralized)

How Repos Work:

  1. Party A sells securities to Party B
  2. Party A agrees to buy them back at a higher price
  3. The difference is the interest earned by Party B

Reverse Repo: From the buyer's perspective (Party B), it's a "reverse repurchase agreement."

Fed and Repos: The Federal Reserve uses repos extensively to manage the money supply and implement monetary policy.
