Agency mortgage-backed securities (MBS) are quietly coming off their best year since 2002 — climbing over 8.5%. So far, the macroeconomic backdrop of 2026 suggests last year's rally was far from a fluke.

The ETF industry has carried its record-breaking momentum from 2025 into the new year, surpassing $100 billion in net flows before the end of January.  By the end of the month, flows into U.S.

Mortgage-backed securities (MBSs) ETFs have, somewhat quietly, welcomed some big new players in the past year.  Just this week, Eaton Vance debuted the Eaton Vance Mortgage Opportunities ETF (EVMO).
