Core conclusion · Tlines extraction
SMBC argues Treasury demand has shifted from buy-and-hold investors, especially foreign official institutions, toward hedge funds that rely on repo funding. Using Federal Reserve Board elasticity estimates, the note calculates the market's demand sensitivity has roughly doubled since 2012 to about 14%. Each 1 percentage point ($300bn) supply increase is estimated to raise 5y yields about 8bp. Hedge fund repo borrowings rose nearly 6-fold to $3.4trn, which may further amplify yield sensitivity and market fragility, though this could be understated or overstated depending on data limitations.

Key arguments
- Treasury demand has shifted from price-insensitive buy-and-hold investors to hedge funds, raising the market's aggregate yield elasticity to about 14%, roughly double the 2012 level.
- Because hedge funds finance purchases with short-term repo borrowing—up nearly 6-fold to $3.4trn—yield sensitivity may be larger than elasticity estimates alone imply.
- Higher elasticity means the Treasury must offer more yield to place new supply; each 1pp (~$300bn) supply increase is estimated to lift 5y yields about 8bp.
- Greater reliance on financing concentrated among large hedge funds and GSIB lenders may increase market fragility, as seen when shocks force deleveraging and dealers retreat.
Key numbers
- Market demand elasticity (2026)
- ~14%
- 5y yield impact per 1pp (about $300bn) supply increase
- ~8bp
- Hedge fund repo borrowings
- $3.4trn, up nearly 6-fold
- HHHF Treasury holdings
- ~$6trn; ~20% of total
- China Treasury holdings
- <$700bn, halved
Main risks
- Hedge fund exposures may be overstated because the Fed's household/hedge fund data include a $1.7trn discrepancy residual and use netted positions.
- Repo financing is concentrated: the top 10% of hedge funds account for nearly 50% of collateralized borrowing, mostly from GSIB banks.
- Shocks to funding rates or margin requirements could force rapid selling, overwhelming dealer liquidity and widening off-the-run spreads, as in March 2020.
Corresponding source evidence
First, because the demand for Treasuries has shifted from buy-and-hold investors to hedge funds.
Monin estimates that hedge funds’ cash futures basis trade accounted for as much as 3.5% of Treasury demand .
1 • We estimate this shift has roughly doubled the market’s yield elasticity since 2013 .
