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:

In a previous note, we looked at mortgage trends derived from the recent release of 2022 HMDA data[1]. Of course, HMDA is a prime data source for analysts and policymakers who seek to understand how social and economic trends interact. The most discussed issue is the distribution of originations by race. Below find a bar chart for the share of originations by race annually from 2004-2022 by loan count:

The cherry blossoms are blooming, which means it’s time for the HMDA preliminary data set to be released. The dataset provides a social underpinning to the nation’s mortgage market and enhances our understanding of the behavior of borrowers and lenders. The 2022 dataset has been particularly eagerly awaited, as we get our view on the new world of high inflation and mortgage rates for the first time in decades. We start with origination volumes and get not just confirmation of the onset of mortgage winter, but some breakdown of its characteristics.

With all eyes on the turmoil in the banking sector, it’s good to see that policymakers continue to innovate to help borrowers. Earlier this month, HUD published Mortgagee Letter 2023-06 “Establishment of the 40-Year Loan Modification Loss Mitigation Option”, which establishes the 40-year standalone Loan Modification into FHA’s COVID-19 Loss Mitigation policies[1]. The standalone 40-yr mod is scheduled to be implemented by May 8. This follows the establishment of a 40-yr modification with a partial claim in April 2022[2]. The introduction of standalone 40-yr mods reminded us that we haven’t focused on the progress of the 40-year mod with a partial claim identified by pool prefix “ET”. Below find a chart of issuance by program:

In recent posts, we introduced the phrase “Mortgage Winter” to describe the current environment where high-interest rates and elevated home prices lead to a severe drop in transaction volumes[1]. Subsequently, we looked at the impact of this situation on individual market participants[2]. The bulk of market participants across the mortgage ecosystem is experiencing year/year revenue declines of two-thirds or more. These entities are having to adjust their business models to this situation and develop strategies to navigate the uncertain environment ahead.
​
Spring will come, but whether the ensuing rebound will be sufficient to return the sector to a state of financial health is a question that remains far from assured. There is also another factor to consider besides revenue, and that is the potential for increased servicing costs associated with delinquent borrowers.

In a recent post[1], we spoke about how the current market environment of high interest and home prices is leading to downward pressure on both supply and demand in the housing market, a situation we call "Mortgage Winter". While this environment is unlikely to result in a severe recession such as the Global Financial Crisis, there is the potential for broad fallout associated with distress in the lender and broker markets.

First, we look at the originations.

The count of loans that were delivered to the three agencies dropped by 68% from Q4 2021 to Q4 2022:

With 2022 at a close, we can begin to assess the impact of the extraordinary shocks of the past few years on the mortgage market landscape. The boom-bust nature of the housing market since the onset of the Covid-19 pandemic has resulted in an unprecedented degree of uncertainty about the outlook. Most commentary in this regard is understandably focused on home prices, but in the end, real estate is a transactional business, and we focus on that market aspect here:

Recursion has undertaken an intensive effort to compute the size of the Agency CMO market back to 2000. The size of the Agency CMO market is calculated by building up from the loan level. This data is provided by agency disclosure of the portfolio of each collateral group and collected from text files, pdfs, and other formats across single-family and multifamily CMOs. The formats of the disclosure files differed across agencies and changed over time, presenting a challenge to unify.
