2023 is not 2007
The underlying problem in the GFC was excess leverage. People, companies, and banks had borrowed so much that a small change in the value of their assets or the cost of borrowing had systemic effects.
But the aggregate consumer, as we have discussed, is nowhere near as leveraged today as they were in 2007, and neither is the financial system. Bank balance sheets are generally much stronger than they were in 2007, in part due to lessons learned in the GFC, and have improved as banks took steps to prepare for higher interest rates and a potential recession. While some could say it took the collapse of Silicon Valley Bank and Credit Suisse to focus global banks on the risks, we believe the problems with these banks were more internal than systemic, and there is ample evidence the banking system as a whole is much better capitalized than it was in 2006.
Finally, the stock of mortgages today is different than it was in 2007. In the years leading up to the GFC, sub-prime mortgages (loans made to borrowers with low credit ratings) were around a quarter of all mortgages. Today, it is in the high single digits.
While it is difficult to find evidence of the frailty that was present in either the consumer or the financial system in 2007, we are mindful that few saw the evidence in 2007 either. And on the face of it, the funds required to afford a mortgage today, with rates and prices where they are, seems unsustainable.
However, in the broadest terms, we believe current home prices are largely a function of low supply, coupled with high demand, and it will take a significant change in either one of those variables to cause the market to reset at significantly lower prices. More likely, in our view, home prices cool, maybe correct modestly, and the housing market muddles through until falling interest rates lower borrowing costs, improving affordability. And while turning points in any market are always fraught with uncertainty, we just don’t see high enough levels of leverage anywhere in the corporate, consumer, or financial sectors to suggest a small decline in home prices could trigger the kind of viscous spiral that happened in the GFC.
Finding investment opportunities in mortgages
The residential mortgage-backed securities (MBS) that are part of so many benchmark bond indices are guaranteed by the issuing Federal agencies, such as Fannie Mae or Freddie Mac, so they carry the same credit rating as the U.S. Government. As such, we are not worried about credit (default) risk in traditional bond benchmarks whatever the outcome of the current housing affordability problem the country faces.
However, many of these same securities have seen a drop in prices as banks have sold them in an attempt to improve the quality of their balance sheets. (Mortgages are long-maturity assets while banks fund themselves with short-maturity cash deposits). In our view, these securities may have upside relative to other benchmark bond asset classes as supply and demand for them normalizes.
Similarly, mortgages which do not conform to the agencies’ standards for guarantees (so called “non-conforming” mortgages) may also offer attractive valuations. In part due to lingering effects from (largely warranted) criticism of the agencies’ ability to assess risk after the GFC, they let the pendulum swing. Today, the due diligence, credit enhancement, loss protection, and third-party oversight provided by many of these securities may provide compelling valuations, especially considering yields offered are often well in excess of that provided by similarly rated corporate bonds.
Finally, the prevailing mortgage rate is currently unusually high relative to government bond yields, suggesting it may have been driven higher by uncertainty about how high Treasuries could go, not how high they are. The figure below shows the prevailing 30-year mortgage rate (the orange line), the benchmark 10-year U.S. Treasury rate (the blue line) and the difference between the two (the white line). At near 3%, the excess yield over Treasuries that consumers must pay to get a mortgage is near the 25-year high.
