AGNC’s (AGNC) annualized net interest spread, including the TBA positions and interest rate swaps and excluding “catch-up” premium amortization, for Q4 was 2.74% vs. 2.81% in Q3. “Fixed income markets stabilized over the quarter, and investor sentiment improved as volatility and monetary policy uncertainty began to subside,” said AGNC (AGNC) President and CEO Peter Federico. “Against this backdrop, Agency MBS spreads to benchmark rates tightened from historically wide levels, driving the meaningful improvement in our tangible net book value per common share during the quarter, both of which continued into January.” Cash and unencumbered agency MBS totaled ~$4.3B at Dec. 31, 2022, increasing/declining from ~$3.6B at Sept. 30.
