Here's what's going on. In the past three weeks, there are $210BN in ACTUAL deposit outflows, which the Fed has "converted" into only $18BN in seasonally adjusted outflows. This means that according to the Fed, deposits will see another $192BN in tax-related inflows.
Last week it was seasonal adjustments; this week it is reclassification. The Fed has reclassified large bank deposits by $100BN to $10.7 trillion from $10.6 trillion, and reclassified small bank deposits by $100BN to $5.25 trillion from $5.35 trillion.
