Bond Market Braces for Record Auction Sizes for Some Treasuries

When the Treasury Department previews its note and bond auction sizes for the next three months on Jan. 31, some of the projected sizes are likely to be the biggest investors have ever seen.

The sizes of the US government’s monthly two- and five-year notes are already at peak levels. On Tuesday and Wednesday, $60 billion of two-year notes and $61 billion of five-year notes were sold. Each amount matched the most ever for the tenor. The biggest-ever size for any Treasury note or bond auction was $62 billion, for seven-year notes sold between January and October 2021.

When the last quarterly round of auctions was announced in November, Treasury officials said they anticipated “one additional quarter of increases to coupon sizes will likely be needed,” suggesting the two- and five-year sales will break new ground. If November’s increases are repeated for the coming quarter, the April five-year auction will be $70 billion, 63% bigger than a year earlier.

“There is absolutely no precedent for the pace and magnitude of these supply increases” during a period of economic expansion, said William O’Donnell, rates desk strategist at Citigroup Inc.

“There has been enough demand to meet the rising supply for now” — witness the steep yield declines since October — “but if inflation doesn’t continue to make progress and market hopes for rate cuts are even partly dashed, supply is going to become a problem and could be an accelerant to the upside,” he said.

Treasury yields have declined by about a percentage point in anticipation that the Federal Reserve — which raised interest rates 11 times during the past two years to arrest a surge in inflation — will begin lowering them this year.
