Treasury auctions and the quiet USD nudge
The US Treasury sells large amounts of debt on a regular schedule, and the results of those auctions can nudge yields and, through them, the dollar. A weak auction pushes yields up fast, and USD pairs can respond within seconds.
The effect is usually modest compared with a major data release, but it arrives at predictable times, mostly in the early afternoon New York time, and catches scalpers who are watching nothing but price.
Pairs with high sensitivity to yields, like USDJPY, respond most. A tail on a 10 year or 30 year auction can produce a sudden burst of movement that looks like news with no headline.
A calendar of auction times, with the bigger ones marked, is easy to build. Over a few months, a trader can see which auctions tend to matter and which can be ignored.
The tail on an auction, the gap between the expected yield and the actual one, is the number to look for in the results. A small tail means nothing. A large one marks a surprise, and the dollar reaction can arrive within seconds.
Has a bond auction ever explained a sudden dollar move that seemed to come from nowhere?
