🏦 Why Do Banks Bother with Investment Securities?
Imagine a bank as a hyperactive squirrel. It stores nuts $($cash$)$ for winter $($economic downturns$)$ and pulls them out when hungry. These “nuts” are investment securities, often making up 20% to 33% of a bank’s assets.
Key Roles of Investment Securities:
- Income stabilization
- Risk hedging
- Diversification and liquidity
- Tax efficiency
- Balance sheet strength
- Emergency cash source
- Collateral utility
They’re known as “crossroads accounts”—pivoting between borrowing and lending as cash needs shift.
👉 But how do we organize these securities to make sense of their behavior and purpose?
⌛ Classification: It’s a Matter of Maturity
Investment securities are sorted by maturity, i.e., “How soon do I get my money back?”
- Money Market Instruments: Mature in ≤ 1 year $($short-term$)$
- Capital Market Instruments: Mature in > 1 year $($long-term$)$
Money market instruments are like speed dating: quick and cautious. Capital market instruments are like long-term marriages: deeper, riskier, more rewarding.
👉 Let’s start with the sprinters—what makes money market investments tick?
🏁 Money Market Instruments: The Speedy Saviors
1. Treasury Bills $($T-Bills$)$
- Zero-coupon, sold at discount, mature at par
- Backed by U.S. federal government—ultra-safe
- Yield = difference between issue and maturity price
🧠 Key term: Bank Discount Method – the method used to quote T-bill returns
👉 But what happens if you want your investment to pay regular interest and live longer than a year?
2. Treasury Notes $($T-Notes$)$ and Treasury Bonds $($T-Bonds$)$
- T-notes $($up to 10 years$)$ and T-bonds $($more than 10 years$)$ become short-term if nearing maturity
- Coupon-bearing, liquid, collateral-friendly
👉 Still curious about other options with slightly higher returns but implicit government support?
3. Federal Agency Securities
- Issued by:
- Fannie Mae $($Federal National Mortgage Association$)$
- Freddie Mac $($Federal Home Loan Mortgage Corporation$)$
- Farm Credit System
- Federal Land Banks
- Not explicitly government guaranteed—but close
- Offer higher yields than direct U.S. debt
👉 But what about options from the banking sector itself, especially those that come with insurance?
4. Certificates of Deposit $($CDs$)$
- Bank-issued, fixed term, insured by the Federal Deposit Insurance Corporation $($FDIC$)$
- Attractive for low risk and better-than-T-bill yields
👉 Moving internationally—what if we step outside the U.S. and look at global short-term options?
5. Eurocurrency Deposits
- Issued by large international banks, mainly in London
- Short maturities, higher yield than U.S. time deposits
- Not insured, exposed to interest rate risk
👉 So what if you’re dealing with global trade and need a guaranteed payment tool?
6. Bankers’ Acceptances $($BAs$)$
- Used in trade finance
- Bank guarantees payment on behalf of a client
- Issued at a discount, tradable, eligible at the Federal Reserve Bank
👉 Now let’s look at corporations issuing their own short-term instruments. What do they offer?
7. Commercial Paper $($CP$)$
- Issued by large corporations, up to 90 days
- Discounted, taxable, widely used in money market funds
👉 Governments issue short-term notes too—but how do they differ from federal debt?
8. Short-Term Municipal Obligations $($TANs and RANs$)$
- TANs: Tax Anticipation Notes
- RANs: Revenue Anticipation Notes
- Interest is usually exempt from U.S. federal income taxes
👉 So, that wraps up the fast lane. What if we need longer-term investments with potentially higher returns and risks?
🧱 Capital Market Instruments: Long-Term, Big Game Players
1. Treasury Notes and Bonds $($At Issuance$)$
- Long-term versions with higher yield than T-bills
- Liquid, safe, useful as collateral
- Price volatility is higher
👉 Besides federal government, who else issues debt—and what do they offer?
2. Municipal Bonds
- Issued by states/cities
- Interest is often federally tax-free
- Two types:
- General Obligation Bonds $($GO Bonds$)$
- Revenue Bonds
- GO Bonds: Backed by taxes
- Revenue Bonds: Backed by project income
👉 And what about the corporate world? Surely they have something spicy to offer.
3. Corporate Notes and Bonds
- Notes: ≤ 5 years | Bonds: > 5 years
- Types: Debentures, Mortgage-backed
- Higher yields = Higher credit risk
- Popular with insurance firms and pension funds
👉 Hold up—what about those weird, complex instruments we keep hearing about?
🧪 More Recently Developed Investment Instruments

👉 What if we pool together loans and sell pieces to investors—what kind of magic is that?
