IEF (7-10 Year Treasury ETF)
The iShares 7-10 Year Treasury Bond ETF, used as a proxy for the intermediate-duration segment of the US Treasury curve. The intermediate part of the curve is where most institutional duration sits, which makes IEF a clean proxy for the rate environment that prices duration risk and re-prices long-tail collateral. IEF is the third pillar of the TBL Liquidity framework.
