This link should look familiar. Ken has been providing it for years in his CD Rates Summary blogs. It’s a handy resource during a period of changing interest rates. It provides a list of the current leading rates in the secondary market of Treasuries offered through Vanguard. It also provides a list of the current leading rates of new issue, non-callable brokered CDs offered through Vanguard. In addition, the link occasionally displays some new issue, callable brokered CD rates. Those rates have recently been listed in the 7 year and 10+ year CD categories. Fidelity offers a comparable link; however, you need an account to view it.
