Pyth has launched new Constant Maturity U.S. Treasury indices, covering seven maturities from 2 to 30 years. These indices provide live Treasury yields and discount factors, with updates every 200 milliseconds. Unlike feeds that track a specific Treasury bond, these indices follow a fixed maturity. For example, the 10-year index always represents a hypothetical Treasury with exactly 10 years remaining, even as the underlying bonds change after auctions. Each of the seven maturities has two feeds, both calculated from the same Treasury curve at the same time: → Par Yield: Shows the interest rate for that maturity. It’s useful for tracking rates and comparing different maturities, such as the 2-year and 10-year yields. → Discount Factor: Shows the present value of a dollar to be paid in the future. This helps with valuing future payments and cash flows. The official U.S. Treasury curve is published once a day, using market quotes taken around 3:30 PM New York time. Pyth’s indices, however, stream throughout their weekday session, from 2:30 AM to 5 PM New York time. This gives platforms access to updated Treasury curve data as markets react to economic news and Fed decisions. The seven live maturities are 2Y, 3Y, 5Y, 7Y, 10Y, 20Y and 30Y. With two feeds for each maturity, that’s 14 live indices in total. Pyth continues to expand its indices offering with more traditional financial market data.
