SOMA securities decreased through November, guided by monthly caps. The FOMC further slowed the pace of Treasury runoff (light blue) by reducing the cap on Treasury redemptions in April from $25 billion to $5 billion, while agency MBS caps were unchanged. As a result, agency MBS accounted for most of the balance sheet reduction during the year (bright blue).
At its October meeting, the FOMC announced the end of balance sheet runoff, effective December 1. The FOMC subsequently announced the start of reserve management purchases at its December meeting to maintain ample reserve levels on an ongoing basis. The SOMA portfolio has declined by over $2 trillion since balance sheet runoff began in mid-2022.
