Historically where is the fed funds rate relative to the 2 year? Is it Always a bit below it and usually by how much or is it higher ?
Unfortunately my abilities do not extend to helping you interpret charts. The one you want though is the Chart of fed funds rate and Treasury yields from 1970 forward. On March 15, 2020, the Fed announced it had reduced the reserve requirement ratio to zero effective March 26, 2020. As of January 2022, this reserve requirement was still in effect. We are now in Sept 2022, please check the fed site, Regulation D I believe. You may want to see if that has changed in the past few months. So far as I'm aware it hasn't, but perhaps I am wrong about that. I would not be surprised to see that the fed has again imposed a reserve requirement -- though such is obviously not an essential component of a funds rate control mechanism.
And I can't help if you continue to choose to speak in cryptic language. What exactly did excite you so much that you wanked all over the thread? That different tenors' yields all converged vs past differentials?
