Digest

This podcast delves into the mystery surrounding the recent surge in mortgage interest rates, which have been significantly higher than expected compared to 10-year treasury bonds. The podcast explains that the traditional relationship between mortgage rates and treasury bonds, where mortgage rates typically hover around 2 percentage points higher, has broken down in recent years. This breakdown is attributed to several factors, including economic uncertainty following the COVID-19 pandemic, increased risk premiums in the wholesale mortgage market, and risk aversion among retail banks following recent bank failures. The podcast uses an analogy of gasoline production and distribution to explain the economics of mortgage interest rates, highlighting the three key components: the 10-year treasury bond, the wholesale mortgage market, and the retail banks. It discusses how risk premiums in the wholesale market are influenced by investors' concerns about borrowers prepaying their mortgages early, which reduces their potential returns. Retail banks, on the other hand, add a percentage point to the wholesale mortgage rate to cover their operating costs and financial risks. The podcast further explores the impact of recent bank failures, particularly Silicon Valley Bank, on the retail banking market. These failures have increased risk aversion among banks, leading to less competitive pricing and higher mortgage interest rates. The podcast suggests that retail banks may be engaging in a coordinated response, avoiding aggressive competition to drive down interest rates. This lack of competition benefits banks but results in higher costs for borrowers. Despite the current high mortgage rates, the podcast concludes with a hopeful outlook, noting that the Fed's interest rate cuts are expected to bring down mortgage rates. However, the oversized spread between mortgage rates and treasury bonds remains a concern, suggesting potential for further reductions in the future.

The Breakdown of the Traditional Relationship

The podcast explains the historical relationship between mortgage interest rates and 10-year treasury bonds, where mortgage rates typically hover around 2 percentage points higher. However, this relationship has broken down in recent years, leading to higher mortgage rates for borrowers.

The Economics of Mortgage Interest Rates and the Role of Risk Premiums

This chapter delves into the economic factors that influence mortgage interest rates, using an analogy of gasoline production and distribution. It explains the three key components: the 10-year treasury bond, the wholesale mortgage market, and the retail banks. The chapter also discusses the role of risk premiums in the wholesale mortgage market, where investors are concerned about borrowers prepaying their mortgages early, which reduces their potential returns. This risk is factored into the interest rates, leading to a higher cost for borrowers.

Retail Banks, Interest Rate Spreads, and the Impact of Bank Failures

The chapter examines the role of retail banks in setting mortgage interest rates. Banks add a percentage point to cover their operating costs and financial risks. The podcast highlights the recent widening of the spread between mortgage rates and treasury bonds, resulting in higher costs for borrowers. The chapter also discusses the impact of recent bank failures, particularly Silicon Valley Bank, on the retail banking market. These failures have increased risk aversion among banks, leading to less competitive pricing and higher mortgage interest rates.

Keywords

Mortgage Interest Rates


The cost of borrowing money to purchase a home, typically expressed as an annual percentage rate (APR). It is influenced by various factors, including the 10-year treasury bond, risk premiums, and bank competition.

10-Year Treasury Bond


A debt security issued by the US government with a maturity of 10 years. It serves as a benchmark for interest rates in the financial market, influencing mortgage rates and other borrowing costs.

Risk Premium


An additional cost added to interest rates to compensate lenders for the risk of borrowers defaulting or prepaying their loans early. It reflects the uncertainty and potential losses associated with lending.

Wholesale Mortgage Market


The market where mortgage lenders buy and sell mortgages before they are sold to borrowers. It plays a crucial role in setting mortgage interest rates, adding a risk premium to the cost of borrowing.

Retail Banks


Banks that directly lend money to consumers, including mortgages. They add a margin to the wholesale mortgage rate to cover their operating costs and financial risks.

Bank Failures


The collapse of a bank due to financial instability or mismanagement. Recent bank failures, such as Silicon Valley Bank, have increased risk aversion among banks, leading to higher mortgage interest rates.

Coordinated Response


A situation where multiple entities, such as banks, act in a similar way without explicit collusion. This can lead to a lack of competition and higher prices for consumers.

Q&A

  • Why have mortgage interest rates been higher than expected compared to 10-year treasury bonds?

    The traditional relationship between mortgage rates and treasury bonds has broken down due to economic uncertainty, increased risk premiums in the wholesale market, and risk aversion among retail banks following recent bank failures.

  • How do risk premiums affect mortgage interest rates?

    Lenders add risk premiums to compensate for the risk of borrowers prepaying their loans early, which reduces their potential returns. This risk is particularly high when interest rates are falling, as borrowers are incentivized to refinance at lower rates.

  • What role do retail banks play in setting mortgage interest rates?

    Retail banks add a margin to the wholesale mortgage rate to cover their operating costs, financial risks, and profit. They also compete with each other to attract borrowers, which can influence interest rates.

  • How have recent bank failures impacted mortgage interest rates?

    Bank failures have increased risk aversion among banks, leading to less competitive pricing and higher mortgage interest rates. Banks are now more cautious about lending, resulting in a higher cost for borrowers.

  • Is there any hope for lower mortgage interest rates in the future?

    The Fed's interest rate cuts are expected to bring down mortgage rates. However, the oversized spread between mortgage rates and treasury bonds remains a concern, suggesting potential for further reductions in the future.

Show Notes

Even with falling interest rates in recent weeks, mortgage rates are still higher than you'd expect.

Mortgage interest rates are usually a little less than two percentage points higher than what you would get on a 10-year Treasury bond. But for the last couple of years that difference has been noticeably higher: 2.6% at the moment. New borrowers have been paying potentially thousands of dollars extra each year on their mortgages.

Today on the show, how mortgage interest rates work and why they're currently out of whack ... with new borrowers footing the bill.
