With a national debt of USD 36 trillion and a budget deficit of USD 307 billion in February alone, the US has to sell a substantial volume of bonds. Every month, the US Department of the Treasury sells approximately USD 40 billion in 10-year Treasury Notes at a single auction – followed the next day by an auction of over USD 20 billion in 30-year bonds. This sudden influx of new supply temporarily puts pressure on the market.

The future on the US 10-year Treasury Note is one of the most liquid instruments in the world, with up to 239,000 contracts exchanged in a single minute. Based on an intraday dataset consisting of 382 million transactions in this futures contract, we investigated the impact of these auctions. This fascinating dataset allows us to observe and analyse market movements with great precision.

The intraday chart in Figure 1 illustrates a clear pattern: ahead of the auction, on average futures prices decline by 6 basis points, only to recover in the hours that follow.

We can benefit from this pattern by taking a short position in government bond futures ahead of the auction, and then switching to a long position just before prices begin to rebound. Our research identifies optimal positioning to efficiently capture this liquidity premium, while carefully taking risk considerations and transaction costs into account.

This auction-based strategy is the first shorter-term signal that we’ve implemented in government bond markets, adding a new, uncorrelated source of alpha to our long-standing Dynamic Duration strategy.
