IEI targets the sweet spot of the Treasury curve where you get meaningful yield without excessive duration risk. It's the Goldilocks choice for investors who find short-term Treasuries too stingy and long bonds too volatile.
How It Works
The fund holds U.S. Treasury securities with 3-7 years until maturity, maintaining an effective duration around 4.5 years. It uses market-value weighting and rebalances monthly to keep maturities in range, rolling down the curve as bonds approach the 3-year mark. This intermediate segment typically captures about 70% of long-term Treasury returns with half the volatility.
Key Features
- Duration of ~4.5 years offers -4.5% price impact per 1% rate rise, versus -17% for long bonds
- Zero credit risk with full U.S. government backing, making it a true flight-to-quality asset
- Highly liquid with tight spreads, often trading $500M+ daily with penny-wide bid-asks
Risks
- A 1% rate spike would knock off roughly 4.5% in price, though you'd earn it back in yield over time
- Real yields often negative after inflation — at 3% yield and 2.5% inflation, you're losing purchasing power
- Opportunity cost versus credit bonds which typically yield 1-2% more for investment-grade quality
Who Should Own This
Perfect for the investor who needs dry powder that won't evaporate in a crisis but can't stomach cash yields. Think of it as your portfolio's shock absorber — it'll zig when stocks zag, but won't crater your returns if rates drift higher. Most useful as a 10-20% allocation for equity-heavy portfolios needing volatility dampening.
