Primary dealer

A trading counterparty of the New York Fed, obliged to bid at every Treasury auction and to make markets in government securities — the channel through which open market operations reach the financial system.

The Fed does not buy bonds from the public. It transacts with a small list of primary dealers, and those dealers are the bridge between the central bank's balance sheet and everyone else's.

The obligation runs both ways: dealers get access to Fed operations, and in exchange must participate in auctions and provide market-making even when it is unprofitable to do so.

Dealer balance sheet capacity is a real constraint on the whole system. When leverage rules or risk limits stop dealers from expanding, repo markets seize even though nothing is wrong with the collateral itself.

The mechanics

Counterparty to
The New York Fed's Open Market Trading Desk.
Obligations
Bid at Treasury auctions; make markets; report positions and flows.
Why capacity matters
Intermediation requires balance sheet, and balance sheet is finite and regulated.

The common misreading

That QE puts money directly into the real economy. It reaches a dealer first, and whether anything travels further depends on what the seller does next.
