1/6 Are Banks Having a Liquidity Problem? tl:dr, Liquidity in the plumbing of the financial system is getting scarce. It is not a crisis now, but it has been moving in this direction for weeks, and it is now at a worrisome point. When the financial plumbing gets stressed, it is when bad loans (aka "cockroaches") get noticed. (long thread, tried to write it so "normies" can follow.) --- Wall Street is famous for diagnosing symptoms, not causes. I believe they are doing this again with the banking issues of the last few days., I do not think this is a "cockroach" problem (bad credit/loans) waiting to get disclosed publicly. It is a liquidity problem that makes the "cockroaches" matter. Banks (all 4,000+) hand out a trillion in loans. So, they will always have "cockroaches." So, it is not an issue of whether cockroaches exist; they always do. Instead, it is the environment in which such disclosures are made. Does the market care or not? Now it cares. Why? --- @NickTimiraos said below: How to define "temporary" and "modest." Repo rates in the last two days have moved up to the top of the fed-funds range and around 10 bps above IORB, but it's only been two days. --- I would argue it has not "only" been two days; worsening liquidity in the funding market has been unfolding for weeks. It just got noticed in the last two days. This chart shows Secured Overnight Financing Rate, or SOFR (orange), and Interest on Reserves, or IOR (blue). The bottom panel shows the spread between these two, along with some metrics (dashed line = average, shaded area = standard deviation range). See the arrow; this spread (3-day average, so it is less noisy) has been tightening for weeks. This spread moved to positive territory in early September and has remained there for weeks. The last time it was positive for this long was in March 2020 (not shown).(Jim Bianco)
