Researchers at the Fed and UC Berkeley have posted Liquidity Crises in the Mortgage Markets. The authors conclusions are particularly troubling:
The nonbank mortgage sector has boomed in recent years. The combination of low interest rates, well-functioning GSE and Ginnie Mae securitization markets, and streamlined FHA and VA programs have created ample opportunities for nonbanks to generate revenue by refinancing mortgages. Commercial banks have been happy to supply warehouse lines of credit to nonbanks at favorable rates. Delinquency rates have been low, and so nonbanks have not needed to finance servicing advances.
In this paper, we ask “What happens next?” What happens if interest rates rise and nonbank revenue drops? What happens if commercial banks or other financial institutions lose their taste for extending credit to nonbanks? What happens if delinquency rates rise and servicers have to advance payments to investors—advances that, in the case of Ginnie Mae pools, the servicer cannot finance, and on which they might take a sizable capital loss?
We cannot provide reassuring answers to any of these questions. The typical nonbank has few resources with which to weather these shocks. Nonbanks with servicing portfolios concentrated in Ginnie Mae pools are exposed to a higher risk of borrower default and higher potential losses in the event of such a default, and yet, as far as we can tell from our limited data, have even less liquidity on hand than other nonbanks. Failure of these nonbanks in particular would have a disproportionate effect on lower-income and minority borrowers.
In the event of the failure of a nonbank, the government (through Ginnie Mae and the GSEs) will probably bear the majority of the increased credit and operational losses that will follow. In the aftermath of the financial crisis, the government shared some mortgage credit losses with the banking system through putbacks and False Claims Act prosecutions. Now, however, the banks have largely retreated from lending to borrowers with lower credit scores and instead lend to nonbanks through warehouse lines of credit, which provide banks with numerous protections in the event of nonbank failure.
Although the monitoring of nonbanks on the part of the GSEs, Ginnie Mae, and the state regulators has increased substantially over the past few years, the prudential regulatory minimums, available data, and staff resources still seem somewhat lacking relative to the risks. Meanwhile, researchers and analysts without access to regulatory data have almost no way to assess the risks. In addition, although various regulators are engaged in micro-prudential supervision of individual nonbanks, less thought is being given, in the housing finance reform discussions and elsewhere, to the question of whether it is wise to concentrate so much risk in a sector with such little capacity to bear it, and a history, at least during the financial crisis, of going out of business. We write this paper with the hope of elevating this question in the national mortgage debate. (52-53)
As with last week’s paper on Mortgage Insurers and The Next Housing Crisis, this paper is a wake-up call to mortgage-market policymakers to pay attention to where the seeds of the next mortgage crisis may be hibernating, awaiting just the right conditions to sprout up.
