# Primary Dealers

**Primary dealers** are the banks and broker-dealers designated by the New York Fed as trading counterparties, and they carry one defining obligation: bid meaningfully at *every* Treasury auction. There are roughly two dozen, names like J.P. Morgan, Goldman Sachs, Citigroup, and Morgan Stanley, and they are the market’s buyers of last resort.

Because dealers must bid whether or not they want the paper, their award percentage is read *inversely*: a low dealer takedown means real investors absorbed the supply; a high one means demand was thin and dealer balance sheets got stuffed. Paper parked with dealers tends to be hedged and redistributed, which weighs on the market for days afterward.

- Healthy coupon auctions in recent years leave dealers with roughly 10–15%.
- Dealer awards above ~20% on a note or bond auction are a red flag, especially alongside a tail.

**Worked example:** A 30-year bond auction tails 2.9bp with dealers awarded 24.6% versus a 14.8% average and indirects sliding to 58%. The read is unambiguous: end-user demand failed and dealers were forced to backstop the sale. Long-end yields cheapen 5bp, and traders expect further pressure as dealers hedge and work the inventory out over the following sessions.

## Questions

### What are primary dealers?

The banks obliged to bid in every Treasury auction and to make markets in Treasuries. They are the buyer of last resort at an auction, which is why their takedown is read backwards: a HIGH dealer share means everyone else stepped back.

### Why is a high dealer takedown a bad sign?

Because dealers are required to bid, so whatever real money does not take, they do. A large dealer share means the paper still has to be distributed and hedged, which pressures the sector for days afterwards.
