LIBOR mortgage

TBAs are the most liquid and important secondary mortgage market, with volume in the trillions of dollars annually. The prevalence of mortgage bonds is commonly credited to Mike Vranos. In other words, the proceeds received would need to be reinvested at a lower interest rate.

Instead, the parties to the trade agree on only five general parameters of the securities to be delivered: TBAs are critical in determining the ultimate interest rates that mortgage borrowers pay, since mortgage originators can "lock in" rates and use TBAs to hedge their exposure.

In Europe there exists a type of asset-backed bond called a covered bond , commonly known by the German term Pfandbriefe. Covered bonds were first created in 19th-century Germany when Frankfurter Hypo began issuing mortgage covered bonds. The market has been regulated since the creation of a law governing the securities in Germany in The key difference between covered bonds and mortgage-backed or asset-backed securities is that banks that make loans and package them into covered bonds keep those loans on their books.

This means that when a company with mortgage assets on its books issues the covered bond, its balance sheet grows, which would not occur if it issued an MBS, although it may still guarantee the securities payments.

There are many reasons for mortgage originators to finance their activities by issuing mortgage-backed securities. Reasons other than investment or speculation for entering the market include the desire to hedge against a drop in prepayment rates a critical business risk for any company specializing in refinancing. Critics have suggested that the complexity inherent in securitization can limit investors' ability to monitor risks, and that competitive securitization markets with multiple securitizers may be particularly prone to sharp declines in underwriting standards.

Private, competitive mortgage securitization is believed to have played an important role in the US subprime mortgage crisis. Off—balance sheet securitizations are believed to have played a large role in the high leverage ratio of US financial institutions before the financial crisis. The weighted-average maturity WAM and weighted average coupon WAC are used for valuation of a pass-through MBS, and they form the basis for computing cash flows from that mortgage pass-through.

The difference goes to servicing costs i. To illustrate these concepts, consider a mortgage pool with just three mortgage loans that have the following outstanding mortgage balances, mortgage rates, and months remaining to maturity:. The weighted-average maturity WAM of a pass-through MBS is the average of the maturities of the mortgages in the pool, weighted by their balances at the issue of the MBS. Note that this is an average across mortgages, as distinct from concepts such as weighted-average life and duration , which are averages across payments of a single loan.

The weightings are computed by dividing each outstanding loan amount by total amount outstanding in the mortgage pool i. These amounts are the outstanding amounts at the issuance or initiation of the MBS. The WAM for the above example is computed as follows:. Another measure often used is the Weighted-average loan age. The weighted-average coupon WAC of a pass-through MBS is the average of the coupons of the mortgages in the pool, weighted by their original balances at the issuance of the MBS.

For the above example this is:. Pricing a "vanilla" corporate bond is based on two sources of uncertainty: The number of homeowners in residential MBS securitizations who prepay increases when interest rates decrease.

One reason for this phenomenon is that homeowners can refinance at a lower fixed interest rate. Commercial MBS often mitigate this risk using call protection. Since these two sources of risk IR and prepayment are linked, solving mathematical models of MBS value is a difficult problem in finance. The level of difficulty rises with the complexity of the IR model and the sophistication of the prepayment IR dependence, to the point that no closed-form solution i.

In models of this type, numerical methods provide approximate theoretical prices. These are also required in most models that specify the credit risk as a stochastic function with an IR correlation.

Practitioners typically use specialised Monte Carlo methods or modified Binomial Tree numerical solutions. Theoretical pricing models must take into account the link between interest rates and loan prepayment speed. Mortgage prepayments are usually made because a home is sold or because the homeowner is refinancing to a new mortgage, presumably with a lower rate or shorter term. Prepayment is classified as a risk for the MBS investor despite the fact that they receive the money, because it tends to occur when floating rates drop and the fixed income of the bond would be more valuable negative convexity.

In other words, the proceeds received would need to be reinvested at a lower interest rate. Professional investors generally use arbitrage-pricing models to value MBS. These models deploy interest rate scenarios consistent with the current yield curve as drivers of the econometric prepayment models that models homeowner behavior as a function of projected mortgage rates.

Given the market price, the model produces an option-adjusted spread , a valuation metric that takes into account the risks inherent in these complex securities. There are other drivers of the prepayment function or prepayment risk , independent of the interest rate , such as:. The credit risk of mortgage-backed securities depends on the likelihood of the borrower paying the promised cash flows principal and interest on time.

The credit rating of MBS is fairly high because:. If the MBS was not underwritten by the original real estate and the issuer's guarantee, the rating of the bonds would be much lower. Part of the reason is the expected adverse selection against borrowers with improving credit from MBSs pooled by initial credit quality who would have an incentive to refinance ultimately joining an MBS pool with a higher credit rating.

Because of the diversity in MBS types, there is wide variety of pricing sources. In general, the more uniform or liquid the MBS, the greater the transparency or availability of prices. Some institutions have also developed their own proprietary software. This is not suitable for risk-averse homeowners.

Flexibility comes at a price as well: An adjustable-rate mortgage is typically the most expensive mortgage model. This is the interest rate banks use to extend each other short-term loans. As a result, the interest rate is market-oriented. Clients can choose how often their rate is adjusted: With a LIBOR mortgage, a term is agreed to just like with a fixed-rate mortgage, except that the interest rate is routinely adjusted.

In the past, LIBOR mortgages have been a practical alternative to a fixed-rate mortgage over the entire term. Their interest rates can vary significantly, however, so there is also an option combining the LIBOR mortgage and the fixed-rate mortgage. In conclusion, there are good arguments for every mortgage model. Which one is right for you depends entirely on your personal situation.

It is especially important to find a balance between security, flexibility, and cost. For instance, while a couple with two incomes may prefer a LIBOR mortgage, a family with limited income may choose a conventional fixed-interest mortgage instead.

The same applies for selecting a term. Someone who chooses a fixed-interest mortgage with a longer term may pay a higher interest rate than for a short term, but it is guaranteed for the stipulated term. Aside from the issue of security, the borrower's own expectations for interest-rate development should also be considered when choosing the term and the mortgage model.

It may be advisable to consult with an expert early on for such decisions. An expert can give an objective outside perspective and keep sight of the bigger picture.
