FIGB Offers Higher Yield Than IEI With Broader Bond Mix but Lower 1-Year Return

The piece compares iShares 3-7 Year Treasury Bond ETF (IEI) and Fidelity Investment Grade Bond ETF (FIGB), highlighting that IEI charges a lower expense ratio (0.15% vs. 0.36%) and focuses exclusively on intermediate-term U.S. Treasuries (84 issues, $17.7B AUM) while FIGB holds a broader mix of ~689 investment-grade bonds (~50% government debt, $354.6M AUM) and yields more (IEI yield 3.5% vs. FIGB 4.15%). Over the past year (to 1/30/2026) IEI returned 2.7% vs. FIGB 2.2%; over four years IEI had a smaller max drawdown (-10.86% vs. -15.62%) and higher terminal growth ($941 vs. $881 per $1,000), indicating IEI is the lower-cost, lower-risk Treasury-focused option while FIGB offers higher income with greater credit exposure and historical volatility.

Analysis

Market structure: The IEI–FIGB comparison crystallizes a tradeoff: ~65bp nominal yield pickup for FIGB (4.15% vs 3.5%) versus a 21bp fee penalty (0.36% vs 0.15%) and materially higher drawdown history (-15.6% vs -10.9% over 4y). Winners are income-seeking allocators and active managers who can absorb credit spread moves (FIGB); losers are duration-averse, liquidity-constrained investors and passive Treasury buyers who prefer IEI’s scale ($17.7B vs $354.6M).

Risk assessment: Tail risks include a rapid Fed-driven rate shock (10y > +50–75bps in <30 days) which would disproportionately hit FIGB via spread widening, and an ETF-liquidity/fire-sale risk given FIGB’s small AUM. Short-term (days–months) payoffs are dominated by rate volatility; medium-term (quarters) by corporate spread cycles; long-term (years) by default/upgrade dynamics in IG credit. Hidden dependency: FIGB’s ~50% government weighting masks concentrated issuer or sector risks within the corporate half.

Trade implications: Implement a risk-managed rotation into Treasuries: prefer IEI as core defensive holding and use FIGB tactically for carry when 10y trade range compresses (<±25bps over 30 days). Concrete tools: duration-neutral pair trades (long IEI/short FIGB) to capture fee and drawdown asymmetry, covered-call or put-spread overlays on FIGB to harvest ~40–60bp net carry while capping downside. Monitor 10y thresholds (3.25%/4.00%) as trade triggers.

Contrarian angle: Consensus favors IEI safety but understates event-driven opportunities in FIGB — a transient spread widening (e.g., IG OAS +50–75bps) could create a tactical buy with asymmetric upside given its higher yield and mean-reverting spreads. Risk is FIGB’s small AUM causing persistent discount and forced redemptions; if FIGB AUM < $200M or spread widening persists >90 days, the trade can become structural rather than cyclical.

Key Decisions for Investors

• Establish a 1–2% portfolio long position in IEI immediately as core intermediate-Treasury exposure; scale to 3–5% if the 10y yield falls below 3.25% (target total return 3–6% over 6–12 months).
• Initiate a duration‑neutral pair trade: long IEI and short FIGB equal dollar notional (~1–2% gross exposure) to capture fee/credit drag; unwind if FIGB’s yield spread to IEI narrows below 30bps or FIGB AUM rises above $1.0B within 90 days.
• If seeking carry, allocate up to 1% to FIGB but hedge tail-risk: buy a 3–6 month FIGB put spread (e.g., 5–7% OTM protection) or sell a 1–2 month covered-call to boost yield, and cap max drawdown at 6–8% via these overlays.
• Set hard monitoring triggers: add hedges (e.g., buy 2y–10y Treasury protection or increase IEI) if 10y rises >50bps in 7 days, or reduce FIGB exposure if FIGB AUM drops >20% in 30 days or IG OAS widens >50bps vs baseline.
