About

Built by people who love fixed income.

Safe Rate started in mortgages: designing a new kind of mortgage, then running a mortgage bank and originating loans ourselves. Every one of those rates starts from the same place, the U.S. Treasury curve. So we went to the source, and built the tools we wanted for the world's largest government bond market.

Why Treasuries

Treasuries are the benchmark every other dollar fixed income security is priced against, and the data behind them is public: Treasury publishes the prices, the debt, the auctions. Yet the tools to use it well, from a fitted curve to attribution, stress tests and an index to measure against, have sat behind terminals and data licenses priced for the largest institutions.

Markets puts them in one place, built only on those primary sources, so a portfolio manager, an advisor, a treasurer or an engineer can manage a Treasury portfolio with institutional-grade tools, and rebuild every number we show.

The founders

Shima and Dylan met during their MBA at the University of Chicago, by way of a study abroad at the London School of Economics, and have built Safe Rate together since.

Shima Rayej

Co-founder

Shima built AI systems for autonomous military vehicles before business school, then structured and priced post-crisis mortgage products on Wall Street.

At Markets she brings the practitioner's view of fixed income portfolio management: how a Treasury book is built, hedged, stress-tested and judged against a benchmark.
