However, the peace and quiet quiet in the repo market was shattered this week, when almost overnight the 10Y went from "normal" in repo, at a rate of 0.50% on Friday, to a special -2.00% on Monday, and then a Super Special, if not record, "fails rate" of -3.50% this morning.
Commenting on this dramatic move in 10Y repo rates, Stone McCarthy's Alan Chernoff, in a note titled "Epic Fail", writes that "the 10-year note has been below the fails rate and shows no signs of moving! It opened at -350 basis points, and though pressure has eased off of it slightly, it is STILL below the fails rate at -300 basis points."
As a reminder, the fails rate is the 300 basis points below the lower end of the target fed funds rate, putting it at -200 basis points currently. And, if an issue falls below the fails rate, it becomes cheaper to just pay the fails charge of 200 basis points rather than deliver than issue, which is what is happening. In dollar terms, the agency repo fails nominal was at $131BN on Sept. 6 vs $153.6 BN on Sept. 5, above the 5-DMA $90.7b, according to DTCC data.
