Bids placed through brokers, mostly central banks and institutions. Sometimes mislabeled as foreigners; the platform's term is Indirect Bidders.
Who these buyers are
Indirect Bidders (Indirect Bidders) are a category in the buyer breakdown of US Treasury auctions: those who buy through a primary dealer rather than directly. In practice they are read as a gauge of demand from foreign institutions and central banks for US debt, since their purchases often pass through this channel.
Why their share is a gauge
Because it is the gauge of the world's appetite for financing America: a high indirect share means international buyers are present in force, a deep and stable demand. Their repeated retreat means the burden shifts to domestic dealers who are obliged to buy. That is forced demand, not desire, and it tends to come before higher required yields.
How to read it correctly
Its trend across consecutive auctions, not a single auction: one odd auction is noise, but three in a row with fading international buyers in the same maturity is a pattern worth noting. This is especially true when it coincides with weak bid-to-cover and long tails. Then the picture of an "international buyer losing interest" is complete.
Hypothetical example
Three consecutive long-bond auctions where the indirect share falls from 68% to 54% with widening tails: the world is demanding a higher premium to hold long debt. That is structural upward pressure on yields, and its effect reaches all stock valuations. The quiet indicator moved before the yield wave.
Common mistake
Reading the share in isolation from the auction's context: a high share in a weakly covered auction may only mean domestic buyers stayed away, not that international buyers were eager. The three numbers (coverage, tail, composition) are read together as one.
Read as a trend, not a snapshot
One odd auction is noise, but three in a row with fading international demand in the same maturity is a pattern, especially when it coincides with weak coverage and long tails. Then the picture of an "international buyer losing interest" is complete, and it is structural upward pressure on yields.
