Macro Note 26
TreasuryDirect says Treasury auctions are open to the public, but the bidding rules split sharply between noncompetitive and competitive participation. The 35 percent limit applies to competitive exposure, not to everyone in the same way.
Why this note matters
Treasury auction commentary often compresses all bidders into a single category. Treasury's own pages draw a more exact map: many entity types may bid, noncompetitive bidders have a different limit structure from competitive bidders, and large competitive bidders must factor in their net long position.
TreasuryDirect says Treasury auction rules specify eligible bidders that include individuals, corporations, partnerships, government-related entities, trusts or other fiduciary estates, and Foreign and International Monetary Authorities. Its auction FAQ adds that there are generally no restrictions on the type of entity that can bid in an auction, subject to the defined categories and rules.
That means access is broad, but not undefined. The rules still distinguish among bidder types and how they may participate.
TreasuryDirect says noncompetitive bidders may bid in amounts from $100 to $10 million in $100 increments and that those bids are awarded in full. By contrast, it says competitive bidders are limited to 35 percent of the offering amount.
Its `Who May Bid?` page adds that a competitive bidder's net long position plus total auction awards may not exceed 35 percent of the offering amount. So the 35 percent concept is tied to competitive bidding and accumulated exposure, not to the basic retail-style noncompetitive lane.
Treasury auction demand is easier to interpret when you know which constraints different bidders are operating under. Treasury's own rules make clear that a retail noncompetitive bidder and a large competitive bidder are not solving the same problem.
For Hynexly readers, the practical rule is simple: when auction participation comes up, ask first whether the bidder is noncompetitive or competitive. The answer changes both the size limits and the reporting rules that apply.
