MBS Weekly Market Commentary Week Ending 06/19/2020

Treasury yields were little changed last week, with virtually the entire on-the-run curve closing within two basis points of the previous week’s marks.  The 2-10 year spread ended the week a half basis point tighter at 50.6 basis points, while the 5-30 year spread widened similarly.  The only notable changes were in the TIPS markets; while the 10-year breakeven rate (a measure of market inflation expectations) widened by just under 9 basis points to +1.29%, the yield on the inflation-adjusted 10-year note declined to -0.615%.  Using the Treasuries constant-maturity index for the 10-year TIPS, this was its lowest reported yield since mid-2013 and reflects expectations for very low “real” interest rates in the future.

MBS struggled last week, as most coupons cumulatively lagged their Treasury hedge ratios by 6-13 ticks.  The Fannie Mae 30-year current coupon spread over Treasuries widened by about 10 basis points, while the Ginnie spread increased by 8 bps.  Dollar rolls continue to trade in excess of their economic values; while June’s Class C notification passed without incident, the offer side of 8/32s for the GNII 2.5 July/August roll is roughly 4+ ticks special.  Fannie 2s are also rolling about 3+ special, while the 2.5 and 3 rolls are special by 1+ to 2 ticks.  One noteworthy landmark was reached on Tuesday, however, when for the first time Fannie 2s were the most actively traded 30-year conventional coupon, with $44.8 billion in daily activity (versus $43.4 billion in Fannie 2.5s).

Both the Freddie Mac and MBA 30-year rates reported new lows last week, which in turn gave a boost to refinancing activity; the MBA’s refi index rose to 3891, its highest level since mid-April.  However, another aspect of this week’s application survey was the continued weakness in ARM applications. The ARM percentage by loan count reported at 2.8%, just a tenth of a percentage point above its low since 2012 and the fifth time since late March that it reported below 3%.  (Note that the ARM percentage by volume, which reported at 7.3%, is also at a multi-year low; it is normally higher than the loan count percentage because average ARM loan sizes are larger.)

The accompanying chart shows the ARM percentage along with the Freddie Mac 30-year survey rate since 2012 and suggests that the ARM percentage and the level of 30-year rates have exhibited a fairly strong relationship over the period.

Click to enlarge One question arises from these data, however:  given the relative levels of the survey rates, why would anyone take an ARM these days?  One factor is the fragmented nature of the ARM market, which differs structurally from the market for fixed-rate loans.  Unlike the fixed-rate market, which is both fairly uniform and driven largely by securitization practices and prices, the ARM market is essentially bifurcated between mortgage bankers and depositories.  Mortgage bankers securitize virtually all their production, and their pricing is strongly influenced (if not dictated) by securities prices; by contrast, depositories are able to hold their production in their portfolios.  Banks and credit unions typically like holding the ARM product, as it fits their interest rate risk profiles better than fixed-rate mortgages.  As a result, it’s often possible for borrowers to find “special” quoted rates from depositories that are well below the ARM survey rates and, by implication, those offered by mortgage bankers.

This in turn raises a number of questions with respect to the future of the ARM product, especially as LIBOR-and CMT-based products are phased out by Fannie Mae and Freddie Mac.  It is entirely possible that the market for ARMs evolves into one dominated by depositories and portfolio lenders, as they will have the freedom to offer products and features not available to lenders subject to agency specifications.
