Auction Metrics Signal Softening Demand - 10Y Auction: Tail of 2.5 bps, high yield 4.25% vs WI 4.225%. Bid-to-cover 2.35 vs 2.50 average. Primary dealer award 22% vs 15% average. Indirect bid 65% vs 70% average. - 30Y Auction: Tail 3.1 bps, high yield 4.45%. Bid-to-cover 2.20 vs 2.35 average. - 2Y Auction: Tail 1.8 bps, high yield 4.80%.

Dealer Absorption and Market Impact Primary dealers absorbed $8.8B of the $40B 10Y auction, up from $6B average. This indicates reduced demand from indirect bidders (foreign and institutional). The 2s10s spread widened to 55 bps post-auction, up from 50 bps. The 10Y term premium rose to 95 bps, reflecting higher risk compensation.

Forward Supply and Concession Build With $120B in coupon issuance this week, the market is pricing a concession of ~3 bps. The 10Y yield is expected to test 4.30% if upcoming 30Y auction tails similarly. Dealer inventories are rising, potentially straining balance sheet capacity.

Trading Implications Recommend underweighting duration, with a target 10Y yield of 4.35% by month-end. Watch for indirect bid recovery in next auction; a print below 60% could accelerate steepening.
