Agency MBS Weekly: A Sticky Summer

Market Recap

Rates bull steepened after the long weekend (ahead of another long weekend next week,

not that we're complaining) as PCE came in below Morgan Stanley expectations and oil

sold off as the Brent curve is now in contango. This ended up reducing some of the hikes

priced into the markets, though of course markets are still expecting a hike around the

October and December meetings. Our economists' outlook for inflation is more sanguine

than the average Fed participant and they think that the Fed will stay on hold this year,

but the data has to cooperate.

This left us with vol modestly lower, but the weakness in equities caused credit spreads to

widen 2bp and stocks to be down almost 2%. While broader risk assets struggled,

mortgages outperformed as expectations of Fed tightening were reduced. The index was

3bp tighter on the week as the stack tightened mostly in parallel. While we're not

surprised that mortgages tightened into lower expectations of Fed hiking, we're surprised

mortgages are doing as well as they are in the face of some possible challenges in the

longer term.

Exhibit 2: Current coupon conventional OAS was 5 bp tighter Exhibit 3: 2s-10s was unchanged while 1yr10yr was 1bp lower
