Every step of managing a Treasury portfolio
From the first trade to the order sheet, on one set of numbers.
Portfolio tracking
Trades by hand or from a broker blotter. Value, income, time- and money-weighted returns against a Safe Rate index, FIFO lots, and attribution to carry, roll-down, the curve's level, slope and curvature, and selection.
Portfolio construction
Fund liabilities by cash-flow matching, immunization or horizon matching; track an index; or start from a ladder, barbell, bullet or bill roll, with lot sizes for retail, Apex, TreasuryDirect or institutional blocks.
Risk and stress testing
Key-rate DV01, standard and custom curve shocks, replays of past market events, value at risk and expected shortfall from filtered historical simulation with extreme-value tails, and fat-tail diagnostics.
Backtesting
Run the strategy templates through every market since 2008, rebalanced monthly to yearly, with trading costs, turnover and drawdowns, against the Safe Rate indices.
Order sheets
Turn a plan into an order sheet with limit prices, split between what TreasuryDirect can fill at auction and what goes to the secondary market. You place the orders yourself, with your broker or TreasuryDirect.
Market analytics
Security lookup; nominal, real, breakeven and money-market curves; auctions and who bought them; on-the-run premiums; rich/cheap to the curve; eleven total-return indices.
Institutional-grade, without the data bill
- Exact-repricing return attribution, linked across days
- Liability-driven construction: cash-flow matching and immunization
- Key-rate durations on twelve tenors, for every security and index
- Value at risk and expected shortfall, with extreme-value tails
- TIPS on real duration and index ratios; floaters on spread duration
- Total-return indices with constituents, float par and analytics by basis
The whole market, from primary sources
Every input is a primary source, published by its issuer and free to anyone. Prices come from the end-of-day file Treasury publishes daily through TreasuryDirect, the statutory prices federal agencies use to value the securities they hold. Amounts outstanding come from the Monthly Statement of the Public Debt, auction results and buybacks from Treasury's Fiscal Data, and Federal Reserve holdings from the New York Fed. No evaluated pricing service, no vendor marks and no licensed data, so anyone can rebuild every number.
What that leaves is a timing difference rather than a data one: Treasury's mark is struck near 3:30 PM, where much of the industry has marked at 4:00 PM since 2021. Safe Rate's indices and analytics are its own construction, not official U.S. Treasury statistics.
Integrate
An API for your systems, MCP for your AI agents
Curves, securities, analytics, rich/cheap, auctions and indices over a REST API with a published OpenAPI reference, and the same tools over an MCP server, so Claude and other agents read the numbers your dashboard shows. One key for both.
