Yield spreads on new-issue hybrid ARMs to Treasuries tightened 1 to 2 basis points last week, which was the result of a modest bond market sell-off that generally sent yields higher across the curve.
Flows in the secondary market for ARMs were relatively high, especially for a holiday-shortened week. Investors continued to buy new issue conventional 7/1s. As we have previously mentioned, this reset type compares well to 10- to 20-year MBS in terms of yield and effective duration, while offering a pick-up of OAS. We also observed demand for GN 3/1 2.5s as investors were drawn to the short end of the curve because of the improvement in yields. The projected yield on a new issue GN 3/1 is currently stands at 2.4%, which is up ~70 bps since the beginning of September 2017.
Finally, there was some selling of seasoned ARMs in the secondary market, primarily post-resets with a weighted average loan age of 150 months or higher. The bid on this type of product has remained strong, due to new supply volumes trending lower.
