Primary dealers are a select group of financial institutions, currently 24 as of 2025, that hold a direct trading relationship with the Federal Reserve Bank of New York. They serve as the structural backbone of the U.S. Treasury market, ensuring auctions clear and secondary markets stay liquid.
As of 2025, there are exactly 24 primary dealers. The group includes the major U.S. broker-dealers: Goldman Sachs, JPMorgan, Morgan Stanley, Bank of America Securities, Citigroup Global Markets, and Wells Fargo Securities. It also includes subsidiaries of major foreign banks: BNP Paribas, Barclays Capital, Deutsche Bank Securities, HSBC Securities, Nomura Securities, and several others. The full list is maintained by the NY Fed and changes infrequently. Additions and removals require formal NY Fed approval and typically coincide with acquisitions, firm failures, or strategic exits from the U.S. Treasury business.
Primary dealers carry two standing obligations in exchange for their privileged access.
Auction participation. The NY Fed sets a guideline that each primary dealer should bid for a "reasonable" share of each auction. In practice, this means bidding for at least the offering amount divided by the number of dealers, roughly 1/24th of each issuance today. When indirect and direct bidder demand is weak, primary dealers in aggregate absorb 50 to 70 percent of an offering. When institutional and foreign demand is strong, that aggregate share drops materially. Dealers are not permitted to sit out an auction entirely. Their bids function as a demand backstop, ensuring the Treasury can issue at a clearing price regardless of broader market appetite.
Market making. Dealers are expected to make continuous two-sided markets in all on-the-run Treasuries and many off-the-run issues throughout the trading day, in minimum size. This obligation is monitored by the NY Fed through transaction reporting under TRACE and direct dealer surveillance. The practical effect is that Treasury investors at any maturity can nearly always find a bid or offer during business hours, even in periods of elevated volatility. Typical bid-ask spreads on on-the-run issues run 0.5 to 1 basis point in price terms under normal conditions.
The auctions tool on this site grades each Treasury auction across several dimensions. One of those inputs is the primary dealer share awarded. When dealers take down more than 50 to 55 percent of a new issue, it typically signals weak end-user demand. Dealers absorb supply at auction expecting to distribute it into the secondary market over subsequent days or weeks. That distribution pressure can weigh on prices post-auction, particularly when the original concession was modest.
A low dealer share reflects the opposite dynamic: strong institutional and international demand, with direct and indirect bidders crowding out dealer allocations. Watching this ratio across successive auctions at the same tenor gives a read on whether demand for that part of the curve is strengthening or deteriorating. The auctions page tracks primary dealer share, indirect bidder share, and direct bidder share for every recent offering.
Primary dealers are the exclusive counterparties for the Fed's open market operations. All transactions conducted through the System Open Market Account (SOMA) at the NY Fed, including outright purchases, sales, and temporary repo operations, flow exclusively through this group.
During QE programs, the Fed purchased Treasuries and agency mortgage-backed securities from primary dealers. QE1 totaled approximately 1.75 trillion, QE2 approximately 600 billion, and QE3 ran at 85 billion per month from September 2012 through October 2014. The COVID-era purchase program began in March 2020 at 120 billion per month. In each case, the primary dealer system was the transmission mechanism, with dealers selling existing inventory to the Fed and using the proceeds to participate in subsequent auctions.
During quantitative tightening (QT), the Fed does the reverse, allowing maturing securities to roll off or selling outright, again through primary dealers. This relationship gives the dealers an information and flow advantage that no other market participant shares: they see Fed intent before it becomes public through FOMC statements.
How does a firm become a primary dealer? A firm applies to the NY Fed's Markets Group and must demonstrate sufficient capital, trading volume in Treasuries, and capacity to fulfill the market-making and auction obligations. Approval is discretionary and not automatic. The process typically takes several months.
Do primary dealers profit from auction participation? Yes, but indirectly. Dealers bid at auction, often receiving securities at a slight concession to fair value, then distribute them to clients in the secondary market. The spread between acquisition cost and secondary market sale price is the source of profit, though inventory risk is real if rates move adversely between auction and distribution.
What happens if a primary dealer fails? The NY Fed removes the firm from the list. Historical examples include Drexel Burnham Lambert in 1990 and Lehman Brothers in 2008. Gaps in primary dealer capacity can temporarily impair auction liquidity, which is part of why the Fed maintains a list of 24 rather than a smaller number.
