Interest-Only During Recessions

John Campbell et al. have posted Structuring Mortgages for Macroeconomic Stability to SSRN. They are not the first to propose a mortgage product that is designed to lessen its burden when times are hard, but that does not make their proposal any the less intriguing. The authors write,

Events in the last decade have shown that adjustable-rate mortgages (ARMs) have advantages over fixed-rate mortgages (FRMs) in stabilizing the economy, at least when the central bank has monetary independence and can lower the short-term interest rate in a recession. A lower short rate provides automatic budget relief for ARM borrowers and helps to support their spending. It can also provide some relief to FRM borrowers, but this requires both a decline in the long-term mortgage rate and refinancing, which may be constrained by declining house prices and tightening credit standards. Barriers to FRM refinancing in the aftermath of the Great Recession were an important concern of US policymakers and motivated the introduction of the Home Affordable Refinance Program.

The authors are certainly right that mortgages were a big drag on households during the Great Recession and many of them (but not all) would have benefited from lower monthly payments. To address this, the authors

study mortgage design features aimed at stabilizing the macroeconomy. Using a calibrated life-cycle model with competitive risk-averse lenders, we consider an adjustable-rate mortgage (ARM) with an option that during recessions allows borrowers to pay only interest on their loan and extend its maturity. We find that this option has several advantages: it stabilizes consumption growth over the business cycle, shifts defaults to expansions, and lowers the equilibrium mortgage rate by stabilizing cash flows to lenders. These advantages are magnified in a low and stable real interest rate environment where the standard ARM delivers less budget relief in a recession.

While there have been some pilot programs that introduce countercyclical mortgage products, nothing has really taken off so far. Hopefully, papers like this will push lenders and regulators to keep looking for solutions to our next housing crisis, before it actually hits.

Mortgaging the Future

The Federal Reserve Bank of San Francisco’s most recent Economic Letter is titled Mortgaging the Future? In it, Òscar Jordà, Moritz Schularick, and Alan M. Taylor evaluate the “Great Mortgaging” of the American economy:

In the six decades following World War II, bank lending measured as a ratio to GDP has quadrupled in advanced economies. To a great extent, this unprecedented expansion of credit was driven by a dramatic growth in mortgage loans. Lending backed by real estate has allowed households to leverage up and has changed the traditional business of banking in fundamental ways. This “Great Mortgaging” has had a profound influence on the dynamics of business cycles. (1)

I was particularly interested by the Letter’s Figure 2, which charted the ratio of mortgage debt to value of the U.S. housing stock over the last hundred years or so. The authors write,

The rise of mortgage lending exceeds what would be expected considering the increase in real estate values over the same time. Rather, it appears to also reflect an increase in household leverage. Although we cannot measure historical loan-to-value ratios directly, household mortgage debt appears to have risen faster than total real estate asset values in many countries including the United States. The resulting record-high leverage ratios can damage household balance sheets and therefore endanger the overall financial system. Figure 2 displays the ratio of household mortgage lending to the value of the total U.S. housing stock over the past 100 years. As the figure shows, that ratio has nearly quadrupled from about 0.15 in 1910 to about 0.5 today. (2)

An increase in leverage for households is not necessarily a bad thing. it allows households to make investments and to smooth their consumption over longer periods. But it can, of course, get to be too high. High leverage makes households less able to handle shocks such as unemployment, divorce and death. it would be helpful for economists to better model a socially optimal level of household leverage in order to guide regulators. The CFPB has taken a stab at this with its relatively new Ability-to-Repay regulation but we do not yet know if they got it right.

SEC Update on Rating Agency Industry

The staff of the U.S. Securities and Exchange Commission has issued its Annual Report on Nationally Recognized Statistical Rating Organizations. The report documents some significant problems with the rating agency industry as it is currently structured. The report highlights competition, transparency and conflicts of interest as three important areas of concern.

Competition. There are some of the interesting insights to be culled from the report. It notes that “some of the smaller NRSROs [Nationally Recognized Statistical Rating Organizations] had built significant market share in the asset-backed securities rating category.” (16) That being said, the report also finds that despite “the notable progress made by smaller NRSROs in gaining market share in some of the ratings classes . . . , economic and regulatory barriers to entry continue to exist in the credit ratings industry, making it difficult for the smaller NRSROs to compete with the larger NRSROs.” (21)

Transparency. The report also notes that “there is a trend of NRSROs issuing unsolicited commentaries on solicited ratings issued by other NRSROs, which has increased the level of transparency within the credit ratings industry. The commentaries highlight differences in opinions and ratings criteria among rating agencies regarding certain structured finance transactions, concerning matters such as the sufficiency of the credit enhancement for the transactions. Such commentaries can serve to enhance investors’ understanding of the ratings criteria and differences in ratings approaches used by the different NRSROs.” (23) The report acknowledges that this is no cure-all for what ails the rating industry, it is a positive development.

Conflicts of Interest.Conflicts of interest have been central to the problems in the ratings industry, and were one of the factors that led to the subprime bubble and then bust of the 2000s.  The report notes that the “potential for conflicts of interest involving an NRSRO may continue to be particularly acute in structured finance products, where issuers are created and operated by a relatively concentrated group of sponsors, underwriters and managers, and rating fees are particularly lucrative.” (25) There is no easy solution to this problem and it is important to carefully study it on an ongoing basis.

The staff report is valuable because it offers an annual overview of structural changes in the ratings industry. This year’s report continues to highlight that the structure of the industry is far from ideal. As the business cycle heats up, it is important to keep an eye on this critical component of the financial system to ensure that rating agencies are not being driven by short term profits for themselves at the expense of long-term systemic stability for the rest of us.
