The US Treasury will auction $39 billion of 10-year notes at 1 PM ET, with the long-end coming into the sale after a sharp rally in bonds that has pushed yields lower toward the 4.25% area.

That move lower in yields—helped by easing geopolitical tensions and softer inflation expectations—could support demand, but traders will be watching closely after a softer result last month, where the auction tailed by 0.7 basis points and dealers were left holding a larger share.

Auction metrics to watch (vs recent averages):

• High Yield: 4.217% prior vs 4.132% six-auction avg
• Tail: 0.7 bps prior vs 0.3 bps avg (weaker demand signal)
• Bid-to-Cover: 2.45x prior vs 2.49x avg
• Dealers: 12.7% prior vs 9.8% avg (higher = weaker demand)
• Directs: 12.8% prior vs 19.2% avg
• Indirects: 74.5% prior vs 71.0% avg (solid foreign demand)

What to expect:

• The lower yield backdrop may help support demand relative to last month
• However, recent concerns about foreign demand and prior soft auctions keep risk tilted both ways
• A stop-through (strong demand) would likely push yields lower and support risk assets
• A tail (weak demand) could reverse today’s rally and send yields back higher quickly

Bottom line:

This is a key test for the long-end after a volatile stretch. With yields off the highs, the market will want to see improved demand vs last month’s weak auction to validate the move lower in rates
