On June 29, 2023, both Fannie Mae and Freddie Mac announced enhancements to their MBS disclosures starting with the September monthly release[1]. The data covers active pools issued back to January 2022. As rates were quite low prior to this time, these disclosures cover the relevant period of high demand for buydowns:

In a recent post, we discussed trends in commercial real estate outstanding debt, with an emphasis on the Agency multifamily market[1]. We mentioned that the key difference between risk sources associated with multi- and single-family debt is that the I/O structure and balloon term that predominates in multifamily loans implies that there is significant refinance risk in this market.
​
We also previously wrote that we have collected all the loans in the major Agency multifamily books and verified that this data was consistent with the Federal Reserve’s Z.1 report[2]. We are now prepared to take some first steps at estimating the extent of this risk. To simplify things, in this note, we look just at the two major GSE multifamily programs, Freddie Mae DUS[3] and Freddie Mac K-deals[4].

To begin, as of August 1, 2023, the Fannie Mae DUS deals account for $384.5 bn or 86% of the total FNM book of $448.1 bn, while Freddie K deals account for $317.9 bn or 83% of $384.9 bn outstanding as of June 1, 2023. Superficially similar.

Below find the maturities for the two programs by year starting in June 2023 for Freddie Mac and August 2023 for Fannie Mae[5]:

We’ve written many, many times about the inexorable rise in the role of nonbanks in the mortgage market[1]. A variety of factors have contributed to these gains, including superior technology, a relatively less oppressive regulatory environment, and Covid-19 chasing people out of bank branches online. 
​
This picture can be a little blurry, however, depending on the way you look at the market. There is, for example, the distinction between servicing book shares and origination shares. Our agency disclosure data doesn’t provide information on originators, but we can use “seller” as a proxy. The table below looks at the trends in outstanding portfolio and issuance for the conforming and Government markets over the period January 2022 – July 2023:

Overview
The release of the Financial Accounts of the United States (also known as the Z.1[1]) is always an opportunity to learn about important structural changes in the mortgage market. This is particularly the case in our current environment of high home prices and borrowing costs which we call “mortgage winter”. In this note, we focus on the breakdown on the ownership of risk for single family mortgages. This is not the share of ownership of MBS; it is who bears the credit risk for the loans.

Unsurprisingly, the growth in single-family mortgage credit outstanding in Q1 grew by the smallest amount in almost 7 years in the first quarter of 2023:

Rising inflation and 30-year mortgage rates near 20-year highs of around 7%, coupled with historically high house prices, have sharply dampened housing demand in the US. This is particularly true for lower-income borrowers where household budgets are badly stretched. These developments have caught the attention of policymakers, who, in response, have taken it upon themselves to lower mortgage fees to partially compensate for these factors.

This is an interesting moment in the formation of housing policy as we have two sets of changes taking effect close together in time. First, FHA announced on February 22, 2023, that it would cut its mortgage insurance premiums by 0.30% to 0.55% effective March 20. More recently, on March 22, GSEs implemented a rather complex set of changes in their upfront fee schedules, effective May 1:

As famous investor Warren Buffett once stated, “Only when the tide goes out do you learn who has been swimming naked.” Well, it turns out that only in a declining market can you see which segments are resilient. In this case, we will look at Planned Unit Developments or PUD’s. A PUD is a planned neighborhood, generally consisting of a group of single-family homes that are bound together by a Homeowners Association (HOA). In this manner, it is like a condo, with the significant difference that the property is usually a stand-alone structure that the buyer owns along with the lot on which it is located. Details about eligibility can be found in Fannie Mae’s selling guide[1].

Below finds the ratio of purchase mortgage deliveries from PUDs to those of 1-4 unit conventional loans:

The release of the Agency performance data in early May provided confirmation that the dip in Early Payment Defaults[1] we have witnessed over the last three months ended a 16-month long uptrend in this statistic for FHA loans. A similar but far more muted pattern can be seen for VA and conventional mortgages. In a previous post, we speculated that the uptrend was correlated with the higher inflationary trend observed since early 2021[2]. Below please find an update of the chart:

As daily April Agency mortgage loan delivery data completed, we found convincing evidence that the freeze in market activities we have witnessed since the fourth quarter of 2022 is continuing, although there are some new twists.

Here is the chart for the loan counts of purchase market deliveries to the GSEs back to 2019. Rather than do this as a time series, we stack the years over an annual monthly x-axis to better correct for the seasonality in the time series:
