Summary

  • Forward 15 year fixed rate mortgages projected to rise from 3.282% today to 5.586% in 2024.
  • Risk neutral values for net servicing rights mixed this week for 15 and 30 year fixed rate mortgages.
  • Forward 10 year U.S. Treasury yield in 2024 down 0.15% from last week.

Kamakura Corporation projections for U.S. Treasuries and fixed rate mortgages this week show that the implied forward rates for 15 year fixed rate mortgages rise from a current effective yield of 3.282% to 5.586% in 10 years, up 0.01% from last week, despite the fall in long term Treasury yields this week. Mortgages tend to react with an erratic lag to changes in Treasury market conditions. Here are the highlights of this week's implied forecast:

  1. The current all-in yield on a 15 year fixed rate mortgage is 3.282%, a change of -0.095% versus last week.
  2. The forward 15 year fixed rate mortgage rate is projected to reach 3.739% in 1 year and 5.586% in 10 years.
  3. The interest only portion of the value of a 30 year fixed rate mortgage this week was 50.92%.
  4. This represents a decrease of -0.71% for the week.
  5. The interest only portion of the value of a 15 year fixed rate mortgage this week was 22.66%.
  6. This is a decrease of -0.51% for the week.
  7. The risk-neutral value of each 0.05% of net servicing on a $100,000 30 year fixed rate mortgage this week was $276.40.
  8. For the 30 year fixed rate mortgage, this represents a decrease of $-1.13 or -0.41% for the week.
  9. The risk-neutral value of each 0.05% of net servicing on a $100,000 15 year fixed rate mortgage this week was $354.75.
  10. For the 15 year fixed rate mortgage, this is an increase of $0.47 or 0.13% for the week.

Data Used in the Analysis

Today's forecast for U.S. Treasury yields is based on the May 29, 2014 constant maturity Treasury yields that were reported by the Department of the Treasury on the same day. The forecast for primary mortgage market yields and the resulting mortgage servicing rights valuations are derived in part from the Federal Home Loan Mortgage Corporation Primary Mortgage Market Survey ® made available on May 28, 2014.

The U.S. Treasury "forecast" is the implied future coupon bearing U.S. Treasury yields derived using the maximum smoothness forward rate smoothing approach developed by Adams and van Deventer (Journal of Fixed Income, 1994) and corrected in van Deventer and Imai, Financial Risk Analytics (1996). The primary mortgage yield forecast applies the maximum smoothness approach to primary mortgage market credit spreads, which embed the market-implied risk neutral probabilities of mortgage default and prepayment risk. References explaining this approach are given below.

Mortgage Valuation Yield Curve and Mortgage Yield Forecast

The zero coupon yield curve appropriate for valuing mortgages in the primary mortgage market is derived from new issue effective yields reported by the Federal Home Loan Mortgage Corporation in its Primary Mortgage Market Survey ®. The maximum smoothness credit spread is produced so that this spread, in combination with the U.S. Treasury curve derived in the link above, correctly values new 15 year and 30 year fixed rate mortgages at their initial principal value less the value of points. The next graph compares the implied 15 year fixed rate mortgage yield with the implied 15 year U.S. Treasury fixed rate amortizing yield over the next ten years.

Mortgage Analysis for This Week

Today's forecast for the mortgage valuation yield curve is based on the following data from the Federal Home Loan Mortgage Corporation Primary Mortgage Market Survey ®:

Only fixed rate mortgage data is used in this analysis for reasons explained in a recent Kamakura mortgage valuation blog.

Applying the maximum smoothness forward rate smoothing approach to the forward credit spreads between the mortgage valuation yield curve and the U.S. Treasury curve results in the following zero coupon bond yields for the primary mortgage market, relative to U.S. Treasuries:

Implied Valuation of Mortgage Servicing Rights

Using the insights of Kamakura Managing Director of Research Prof. Robert Jarrow noted below, we have derived the risk-neutral values of mortgage cash flows, which are based on market implied default risk and prepayment risk. We use these zero coupon bond prices to value mortgage-related cash flows relevant to mortgage servicing rights. These zero coupon bond prices, when multiplied by current primary mortgage market terms, value new mortgages at their principal value less the value of points:

We apply the same mortgage valuation yield curve zero coupon bond prices to various aspects of mortgage servicing cash flows to arrive at the risk-neutral present value of these cash flows:

  1. The risk-neutral valuation split between interest-only and principal-only cash flows.
  2. The levels of net servicing fees.
  3. The net cost to service, assuming costs are a constant dollar amount.
  4. The float per $100 of taxes and insurance on the underlying home. We assume that float is invested at the matched maturity U.S. Treasury forward rate for the matching float period below. The risk-neutral present value of the interest earned is calculated using the mortgage valuation yield curve, since an event of default or prepayment on the underlying mortgage ends this source of value. Value for a constant $100 amount is given below for "float periods" ranging from 1/4 of a month to a full month.
  5. The value of float on the payment of interest and principal for various lengths of the "float period."
  6. The net impact of cash flows to the servicer from the events of default and prepayment. We can analyze this by asking this question: what would be the value of the mortgage if there were no events of default or prepayment? The answer is obtained by applying U.S. Treasury zero coupon bond rates to the scheduled mortgage cash flows. The final table shows the net reduction in certain monthly cash flow that would be necessary for the value of the mortgage to adjust downward from this "no default/no prepayment value" to its current market value, discounted by the U.S. Treasury zero coupon bond prices. This adjusted basis converts the random probability of losses from prepayment and default to a known, certain cost of prepayment and default in the form of this "implied net constant monthly cash flow reduction." The division of this negative cash flow impact between the servicer and other parties depends on the terms of the servicing contract.

The results of the analysis are shown in the following series of tables:

Background Information on Input Data and Smoothing

The Federal Reserve H15 statistical release is the source of most of the data used in this analysis. The Kamakura approach to interest rate forecasting, and the maximum smoothness forward rate approach to yield curve smoothing is detailed in Chapter 5 of van Deventer, Imai and Mesler (2013). The smoothing process for the maximum smoothness credit spread, derived from coupon-bearing bond prices, is given in Chapter 17 of van Deventer, Imai and Mesler (2013).

The problems with conventional approaches to mortgage servicing rights valuation and Kamakura's approach to mortgage valuation yield curve derivation are also outlined here, along with the reasons for smoothing forward credit spreads instead of the absolute level of forward rates for the marginal bank funding cost curve. The academic paper by Prof. Robert A. Jarrow and Donald R. van Deventer outlining the Kamakura approach to mortgage yield curve derivation was published in The Journal of Fixed Income.

The mortgage valuation yield curve insights depend heavily on Prof. Robert A. Jarrow's paper "Risky Coupon Bonds as a Portfolio of Zero-Coupon Bonds," published in Finance Research Letters in 2004.
