We know, we know, a mortgage meltdown sounds like a claim coming out of left field. However, it comes from a potentially big issue that no one is paying attention to—the fact that the Fed is winding down its massive $1.6tn+ mortgage bond portfolio. As the Fed has begun to unwind its MBS portfolio, there are growing worries over the economy and real estate market. This could lead to a mortgage shock. Spreads between MBS and Treasuries have already risen as investors have grown nervous about oversupply.
FINSUM: So this is more of a technical issue than a fundamental one, but given the confluence of negative sentiment and oversupply, there is certainly some significant risk on the horizon for MBS.
