Treasury Basis Trade
A leveraged hedge-fund trade that arbitrages the spread between Treasury cash bonds and Treasury futures — large enough to matter for systemic risk.
Definition
The Treasury basis trade buys cash Treasuries and sells the corresponding Treasury futures, financing the cash leg in repo. The spread is small (a few basis points) but leveraged 50–100x via repo, making it profitable at scale.
The trade has grown to over $1T notional, with concentration in a handful of macro funds. Its main systemic risk is forced unwind: if repo financing seizes or futures margins spike, simultaneous selling of cash Treasuries by basis-trade desks can drive disorderly moves.
Why it matters
The basis trade is one of the largest hidden leverage exposures in fixed income. A forced unwind would amplify any Treasury-market stress.
Worked example
March 2020: a partial basis-trade unwind contributed to the Treasury market dislocation; the Fed's announcement of unlimited QE was partly aimed at stabilizing the basis.
