IEF owns U.S. Treasury bonds maturing in 7-10 years, providing steady income with moderate interest rate sensitivity. This intermediate duration sweet spot captures most of the yield curve's return potential while avoiding the extreme volatility of long bonds.
How It Works
The fund holds roughly 40-50 Treasury bonds weighted by market value, maintaining an average duration around 7.5 years. It rebalances monthly to keep maturities within the 7-10 year window, selling bonds as they approach 7 years and buying new 10-year issues. This mechanical approach ensures consistent duration exposure without active management decisions.
Key Features
- Duration around 7.5 years means 7.5% price drop if rates rise 1% — half the volatility of 20-year Treasuries
- Yields typically 80-90% of long bonds with 40% less volatility, making it efficient risk-adjusted exposure
- Most liquid Treasury ETF in its maturity range with $20+ billion in assets and penny-wide spreads
Risks
- Rising rates hit hard — lost 17% in 2022 when Fed hiked, could see similar drawdowns in future tightening cycles
- Yields barely beat inflation historically, meaning real returns often negative after taxes in normal environments
- Flight-to-quality rallies smaller than long bonds — gained only 6% in March 2020 vs TLT's 12% pop
Who Should Own This
Best for investors needing ballast against equity volatility who can't stomach 20+ year Treasury swings. Works as a portfolio stabilizer for retirees or as dry powder for rebalancing into stocks during crashes. Also useful for expressing medium-term rate views without the noise of credit spreads.
