Direct Answer
Fixed-income arbitrage takes long and short positions in related bonds and interest-rate derivatives to profit from small pricing discrepancies, such as between on-the-run and off-the-run Treasuries, between a bond and its swap, or along the yield curve, with leverage used to make the small spreads worth capturing. It tends to work in calm markets, where liquidity premiums and curve kinks revert predictably and leverage turns basis points into a return. Leverage on small spreads; the strategy's losses are rare, sudden and large, and arrive when funding disappears.

How Does Fixed-Income Arbitrage Work?
Fixed-income arbitrage takes long and short positions in related bonds and interest-rate derivatives to profit from small pricing discrepancies, such as between on-the-run and off-the-run Treasuries, between a bond and its swap, or along the yield curve, with leverage used to make the small spreads worth capturing.
The rules:
- Identify a pair or structure with an economic link: same issuer and similar maturity, a bond and its hedged swap, or adjacent curve points
- Go long the cheap instrument and short the rich one in duration-matched amounts
- Lever within limits set by the spread's historical volatility, not its average
- Set the exit on spread normalization and a hard stop on widening
Worked example. An off-the-run Treasury yielding 7 basis points more than the on-the-run issue of similar maturity offers about 0.63% of price convergence on a 9-year duration if the spread closes, which is why the trade is levered ten times or more. The inputs are illustrative numbers, not market data.
When it tends to work. It tends to work in calm markets, where liquidity premiums and curve kinks revert predictably and leverage turns basis points into a return.
When it fails. It fails in liquidity crises, when every spread widens at once and leveraged positions are liquidated, as with Long-Term Capital Management in 1998 and several relative-value funds in March 2020.
Main risk. Leverage on small spreads; the strategy's losses are rare, sudden and large, and arrive when funding disappears.
