Interest Rate Options (calculated as interest rate risk)
The analysis of interest rate risk is almost always ensure to the simulation of movements in one or more curves Heath-Jarrow-Morton framework, in order that the movement of the yield curve in line with the current yield curve in the money market, it is not without risk to arbitration possible. Heath-Jarrow-Morton was developed in 1990 by David Heath of Cornell University, Andrew Morton, Lehman Brothers, and Robert A. Jarrow and Kamakura Corporation and Cornell University.
There are different standards in determining the impact of changes in interest rates of the portfolio of assets and liabilities. The most common are:
The first market prices is to count the net market value of assets and liabilities, sometimes referred to as “the market value of portfolio investments
Another stress test, moves the market value of the curve in a certain way. Duration of exercise to change the curve is parallel to the
The third portfolio VaR calculation
The fourth period cash flow and other financial income and expenses in the future contours of the future accrued
The Fifth Follow step 4 for random movements of the yield curve and by measuring the probability of cash flow and the accumulation of returns in the long run.
Sixth Fixed-interest measures inequality in assets and liabilities, by classifying all assets and liabilities at the reset interest rates or maturity, whichever comes first.
Banks and interest rate risk
Four banks have interest rate risk:
Hazard function
Risks associated with the return of assets and liabilities are linked to costs according to various criteria, such as the London interbank rate (Libor) are based, have the U.S. rate. In some cases, for different reasons and with different speeds can cause moving in different directions, the adverse changes in income and expenses.
The risk of the yield curve
Risks due to the differences in interest rates in the short term and long term. Short-term interest rates are generally lower than long-term interest rates, and banks will benefit from short-term loans (lower prices) and investment in long-term assets (high). But the ratio of prices in the short and long term, can change quickly and dramatically, causing what is wrong and changes in revenues and costs.
Repricing risk
Risks and liabilities, price changes at different times and prices. For example, a variable interest rate loans produce more income when interest rates rise and less when interest rates fall. If the loan is financed by the quality of deposits, net interest income changes.
The risk-free option
I “, by the voluntary nature that is embedded in certain assets and liabilities are presented. For example, mortgages are an important decision, because the risk of prepayment speeds change dramatically when the rise and fall of interest rates. Interest rates caused many borrowers to refinance and their to repay debt, if the Bank did not invest money in interest. Alternatively, higher interest rates because borrowers pay more slowly, so that more bank loans on the basis of previously less attractive. The risk of this option is difficult to measure and monitor.
The banks most active in the sense, that is, changes in interest rates impact on the profitability of an active responsibility for the tax implications. This is to have large amounts of bank loans involved little or no influence on interest rate changes. The average current account deficit does not earn interest or little interest, so that changes in interest rates do not cause any significant change in interest expense. However, banks have high concentrations of short-term and / or variable interest rates, so that changes in interest rates has a significant share of the revenue. Generally, banks make more money when prices are high, and earn less money when interest rates are low. This relationship often breaks down the big banks, which is based mainly on other sources of finance to traditional bank deposits. Large banks are often sensitive because the responsibility is a set of measures that are sensitive to interest rates. Large banks tend to have a high concentration of fixed rate, which increases the sensitivity of the responsibility to maintain. Therefore, large banks often earn more interest income when interest rates are low.
Mega-projects and the interest rate risk
The interest rate risk has to be particularly important and dangerous, especially for large investment projects on time, the so-called mega-projects. This is due to the fact that the projects are often called by debt and the likely end of what has been financed by the “debt trap”, ie a situation because of cost overruns, delays, unexpected interest, etc. cost of debt service to disposable income is higher interest rates and reducing debt.
Interest Rate
Interest rate risk can be covered by interest from investments and interest. Interest rate risk can be reduced by the purchase of securities of shorter duration, or the introduction of a variable interest rate swaps .
