US Treasury Auction Tracker — Bid-to-Cover & Yield Results

US Treasury Auction Tracker — Bid-to-Cover, Yield & Demand Breakdown

Track US Treasury auction results directly from TreasuryDirect.gov — the official source for all US government debt issuance. Monitor bid-to-cover ratios, high yields, investor category breakdowns (indirect/direct/primary dealers), and auction sizes for Treasury Bills, Notes, Bonds, TIPS, and Floating Rate Notes. No API key required.

Treasury auctions are among the most significant events in global fixed income markets. Weak demand (low bid-to-cover, high stop-through) signals bond market stress, rising yields, and potential spillover into equities and crypto. Strong auctions, particularly with high indirect bidder participation, confirm robust global demand for US debt.

What You Get

Each record represents one Treasury auction:

• cusip — unique security identifier
• security_type — Bill, Note, Bond, TIPS, FRN, or CMB
• security_term — maturity (e.g., "4-Week", "2-Year", "10-Year", "30-Year")
• auction_date — date the auction took place
• issue_date / maturity_date — when bonds settle and mature

Demand Metrics (Primary Trading Signals)

• bid_to_cover_ratio — total bids submitted divided by total accepted. Above 2.5 = strong; below 2.0 = weak demand
• pct_allotted_at_high — percentage of awards made at the highest accepted yield (stop). Higher % = worse tail

Pricing

• high_yield — the highest accepted yield (stop price). This IS the new benchmark rate
• high_discount_rate — for T-Bills (quoted on discount basis)
• interest_rate — coupon rate for Notes, Bonds, TIPS
• high_investment_rate — bond-equivalent yield for Bills

Supply & Demand Volumes

• offering_amount_mm — offered supply (millions USD)
• total_tendered_mm — total bids submitted
• total_accepted_mm — total accepted = offering amount
• competitive_tendered_mm / noncompetitive_tendered_mm — institutional vs. retail

Investor Category Breakdown

• indirect_pct — share awarded to indirect bidders (foreign central banks, international institutions)
• direct_pct — share awarded to direct bidders (hedge funds, proprietary traders)
• primary_dealers_pct — residual absorbed by primary dealers (usually means weak demand)

How to Read Auction Results

Bid-to-Cover Ratio: The single most watched auction metric. At 2.53, for every $1 of bonds offered, $2.53 was bid. Historical averages: 10-Year Notes average ~2.4x, 30-Year Bonds ~2.3x, 2-Year Notes ~2.6x. Significantly below average = market stress.

Indirect Bidders: Foreign central banks, sovereign wealth funds, and international institutions. High indirect bid (65%+) = global confidence in US debt. Declining indirect participation is a structural warning sign.

Primary Dealers: The residual. When indirect + direct bidders are weak, dealers absorb the slack — but this means less organic demand. Dealer-heavy auctions often lead to short-term rate sell-offs as dealers hedge their inventory.

Stop-Through vs. Tail: If the auction clears BELOW the pre-auction yield (WI rate), it's a "stop-through" — bullish (more demand than supply pushed price up). If it clears ABOVE, it "tailed" — bearish (weak demand).

Use Cases

• Bond market stress indicators — watch for declining bid-to-cover trends, especially in the 10Y and 30Y
• Rate direction forecasting — auction results confirm or deny near-term yield moves
• Fed impact analysis — monitor how QT and rising supply affect auction demand
• Foreign demand tracking — declining indirect bidder share signals FX reserve diversification away from USD
• TIPS breakeven analysis — compare TIPS auction demand vs nominal bond demand for inflation expectations
• Macro dashboard automation — alert when bid-to-cover falls below historical averages

FAQ

What is the difference between Bills and Notes? Treasury Bills mature in 4 weeks to 52 weeks and are quoted on a discount basis (no coupon). Notes mature in 2 to 10 years and pay semi-annual coupons. Bonds mature in 20-30 years. TIPS (Treasury Inflation-Protected Securities) are indexed to CPI — the principal adjusts with inflation.

What is the "when-issued" (WI) rate? Before each auction, the security trades in the when-issued market at an expected yield. The difference between the auction stop and the WI rate determines whether it stopped-through (bullish) or tailed (bearish). The TreasuryDirect API does not include WI data.

How often does the Treasury auction securities? The US Treasury auctions securities nearly every business day. T-Bills are auctioned weekly (4-week, 8-week, 13-week, 26-week, 52-week). Notes are auctioned monthly (2-year, 3-year, 5-year, 7-year, 10-year). Bonds quarterly. TIPS roughly monthly.
