The Zero-Coupon Solution: How to Eliminate “Reinvestment Risk” in Your IRA
The Zero-Coupon Solution: How to Eliminate “Reinvestment Risk” in Your IRA
EXECUTIVE SUMMARY
- The Problem: Regular bonds pay interest twice a year. You have to reinvest that cash. If interest rates fall, you are forced to reinvest at lower rates. This is Reinvestment Risk.
- The Solution: Zero-Coupon Bonds (STRIPS) pay $0 interest until maturity. You buy a bond for $500 today, and it pays $1,000 in 20 years. The interest is automatically reinvested at the initial yield.
- The Tax Trick: In a Taxable Account, you owe tax on the “Phantom Income” (interest you didn’t receive) every year. Terrible. In an IRA, the phantom tax is ignored. It is the perfect asset location match.
Most retirees want “Cash Flow.” But smart retirees want “Liability Matching.” If you know you need $100,000 in 2045 for a nursing home, buying a regular bond fund is a gamble (yields fluctuate). Buying a Zero-Coupon Treasury maturing in 2045 guarantees that exact amount. According to Team BMT Analysis, pairing Zeros with an IRA is the only way to lock in a 30-year compound return with zero tax friction and zero reinvestment risk.

Scenario: 20-Year Treasury STRIPS. Yield 5%.
- Taxable Account (Disaster):
You buy for $37,000. It matures at $100,000.
Every year, the IRS says you “earned” interest (OID), even though you got $0 cash.
Result: You pay tax out of pocket for 20 years. Negative cash flow. - IRA Account (Perfection):
You buy for $37,000.
The “Phantom Income” is shielded by the IRA wrapper.
Result: In Year 20, you have $100,000. No tax due until withdrawal.
Reinvestment Risk Comparison
| Bond Type | Interest Rate Sensitivity (If Rates Drop) |
|---|---|
| Regular Bond Fund (BND) | High Risk. Future coupons are reinvested at lower rates. Final wealth drops. |
| Zero-Coupon Bond (EDV) | Zero Risk. The 5% yield is locked for the full 20 years on Day 1. No coupons to reinvest. |
*Chart Note: Zeros are the most volatile bonds price-wise (High Duration), but if held to maturity, they are the least risky income-wise because the final payout is fixed.
CRITICAL SCENARIO: The “Duration” Weapon
Using volatility to your advantage.
| Market Condition | Zero-Coupon Bond Reaction |
|---|---|
| Rates Rise 1% | Price Crashes -20%. (EDV/ZROZ ETFs get crushed). |
| Rates Fall 1% (Recession) | Price Spikes +20%. (Zeroes act like “Super-Treasuries”). |
Execution Protocol
Don’t just buy Zeros for fun. Match them to a future expense. “I need $50k for my daughter’s wedding in 2030.” Buy a strip maturing in 2030.
Individual STRIPS: Best for precise liability matching (Brokerage). ETFs (EDV / ZROZ): Best for general portfolio protection (“Crisis Alpha”). They hold a rolling basket of 20+ year zeros.
Always buy these in a Traditional IRA or Roth IRA. Never in a Taxable account. The OID (Original Issue Discount) tax rules are a nightmare for individuals.
Decision Order: Define Timeline โ Select IRA Account โ Execute Trade.
WEALTH STRATEGY DIRECTIVE
- Do This: Use Long-Term Zero Coupon Treasuries (EDV) as the “Ballast” in your portfolio to offset Equity Risk. In a deflationary crash (2008, 2020), they often go up 40%+.
- Avoid This: Buying Corporate Zeros. If the company goes bankrupt in Year 19, you get nothing. Stick to US Treasuries (Risk-Free Principal).
Frequently Asked Questions
Why are they called STRIPS?
Separate Trading of Registered Interest and Principal of Securities. Investment banks “strip” the coupons off a regular bond and sell the principal and interest separately.
Is EDV safe?
Credit-wise, yes (US Govt). Price-wise, no. It is extremely volatile. It fell ~40% in 2022 when rates spiked. It is a hedging tool, not a piggy bank.
Can I buy them directly?
Yes, at TreasuryDirect or brokers. But liquidity is lower than regular Treasuries. You plan to hold these to maturity.
