9.11.26 Prepayment Speeds; Agile's Greg Vacura on TBA Trading; CPI Inflation

August prepayments strengthened the view that the 2026 refinance wave has peaked, with Fannie 30-year speeds falling 12 percent to 7.1 CPR and Ginnie II also slowing, leaving subdued near-term runoff and greater extension risk, while higher-coupon VA pools and recent Ginnie vintages remain the key latent prepayment risks if mortgage rates decline materially. Robbie interviews Agile’s Greg Vacura on connecting mortgage lenders and broker-dealers to make MBS trading faster, more efficient, transparent, and less reliant on phone-based processes. And rates remain caught between an oversold Treasury market and persistent inflation, fiscal, supply, and geopolitical pressures, with the selloff pushing the 30-year above 5.30 percent and MBS underperforming even after a strong 30-year auction, while rising oil, firm economic data, and a heavy corporate calendar keep the focus squarely on CPI and the Fed’s upcoming decision.
