Last week, concerns of slowing U.S. growth momentum and rising inflation led to a sell-off in equities and sovereign bonds. The yield on the benchmark 10-year note rose 5 bps on the week while the yield on the 2-year note held steady at 15 bps. Policymakers acknowledged the upside inflation data surprise but continued to reiterate the data will be volatile as we emerge from the pandemic. On the week, yield spreads on Ginnie ARMs tightened 5 – 9 basis points and conventional ARMs tightened 2 – 5 basis points. ARMs outperformed their fixed-rate counterparts as 15-year product widened 2 bps and 30-year product was unchanged.
ARM pricing spreads have tightened and are at levels seen during the first half of 2018. Shorter 5/1 conventional ARMs have an 18 bp spread, almost 11 bps wider than median levels from the first half of 2018. Longer-reset 7/1 and 10/1 conventionals have a 22 and 24 bp spread, respectively, approximately 8 bps wider. Adjustable-rate mortgage products remain an attractive place to put excess cash and liquidity without extending duration, regardless of portfolio strategy.
Factors such as diminished liquidity, lack of index sponsorship, and the small market size have slightly increased ARM spread concessions to fixed rates. 7/1s may offer better value than 15-years, but they are less liquid. Overall, we continue to see relative value in 7/1s due to appealing yields, shorter durations, and less negative convexity than comparable-coupon 15-year fixed rate MBS. Investors concerned about potentially faster prepayments could focus on lower-WAC new-issue pools or moderately-seasoned paper.
The ARM origination cycle continued last week with 178.mm in new issue ARM selling split amongst Fannie Mae (102.3mm), Freddie Mac (75.3mm), and Ginnie Mae (.9mm). Supply was concentrated in longer-reset 7yr/6m and 10yr/6m indexed to the 30-day SOFR average with 78.8mm and 88.2mm being issued, respectively. Fannie Mae and Freddie Mac issued 28.6mm and 50.2mm, respectively, of the 7yr/6m indexed to the 30-day SOFR average. Fannie Mae and Freddie Mac issued 63.1mm and 25.1mm, respectively, of the 10yr/6m indexed to the 30-day SOFR average. No 3/1s were issued as this shorter product continues to be largely abandoned by lenders and the GSEs. In recent years, the monthly net supply of ARMs has run at a negative pace, while fixed rate products have grown at a much faster pace. As of May, hybrid ARM issuance represented ~ 0.51% of overall MBS issuance.
ARM Prepay Commentary
The overall prepayment of conventional hybrid ARMs decreased in April after speeding up the last two months. May-released factors indicated the prepayments of FNMA and FHLMC ARMs fell by 9.31% and 7.76%, respectively. The prepayment speeds of FNMA 3/1s, 5/1s, 7/1s, and 10/1s slowed down by 5.91%, 5.7%, 9.5%, and 10.29%, respectively. Similarly, prepayment speeds for FHLMC 5/1s, 7/1s, and 10/1s slowed down by 4.86%, 6.29%, and 13.29%, respectively. The overall prepayments of GN II hybrid ARMs also experienced a decrease of 4.08% in April. For the Treasury indexed GN II hybrid ARMs, the prepayments for GN II 5/1 and 7/1 cohorts fell by 3.49% and 26.48%, respectively. In aggregate, FNMA and FHLMC ARM speeds dropped to 37 and 39.2 CPR while GN II decreased to 37.6 CPR.
Shorter-reset LIBOR-based Fannie 3/1s decreased 1.4 CPR to 22.3 and 5/1s fell 2 CPR to 33.1. Longer-reset 7/1s slowed down 4.4 CPR to 41.9 along with 10/1s, which decreased 4.9 CPR to 42.7. In the Ginnie sector, Treasury-based 3/1s, 5/1s, and 7/1s paid 32.2 CPR, 41.5 CPR, and 43.6 CPR, respectively.
ARM LIBOR Transition Update
The LIBOR to SOFR transition has come to the agency ARM market with more specificity. Directed by FHFA, Fannie Mae and Freddie Mac announced that they will start to wrap SOFR based ARMs later this year although no specific date has been set. The following table from a Vining Sparks’s publication describes the key features of the new SOFR ARM product:
For SOFR ARMs, both agencies introduced a batch of four basic types with standard 3-year to 10-year fixed-rate terms. Each will float off of 1-month SOFR averages with a 6-month reset frequency instead of the 1-year reset that most LIBOR hybrids currently have. Moreover, 1-month SOFR is a backward-looking index rate versus the forward-looking 1-year LIBOR.
A typical 1-year LIBOR loan margin in 225bps. The margin on these SOFR ARMs needs to be higher to compensate for the shorter tenure of the 1-month index. However, a higher reset frequency should also help to offset the term difference. ARRC published a white paper in July 2019 on this topic and recommended that SOFR ARM loan margins be between 2.75% and 3% so that their fully indexed rate may be comparable to the annual reset 1-year LIBOR ARM consumer rate. The agencies did not dictate a margin in the announcement, but it did impose a maximum margin of 300 bps.
The GSEs have recently stated that LIBOR loan applications would not be accepted past September 30, 2020, and they won’t be securitized after December 1, 2020. Fannie Mae will start accepting SOFR ARMs on August 3, 2020, while Freddie Mac will permit them from November 16, 2020 and onward. In their LIBOR Transition Playbook, the GSE’s provided the following timeline, which identifies key transition milestones for SOFR-indexed ARMs:
The administrator of LIBOR has announced it will cease the publication of one week and two-month LIBOR after December 31, 2021, and the remaining tenors after June 30, 2023. Extending the publication of certain LIBOR tenors until mid-2023 would allow most legacy LIBOR contracts to mature before LIBOR experiences disruptions.
The vast majority of ARM loans are retained by banks. The issuance of agency ARMs has been falling since the 2008. Thus, the impact of this transition timeline may be relatively minor. Should the current timeline for agency ARM transition stand, investors might expect lower ARM issuance as we move closer to year-end.
