<p>The Fisher Equation suggests that the spread between nominal and real interest rates is equal to the inflation expectations. In Sweden, where both nominal and inflation linked bonds exist the fisher equation implies that the yield spread could provide investors and policymakers with important information about markets inflation expectations. The aim of this thesis is therefore to estimate whether the yield spread between Swedish nominal and real interest rates - widely referred to as the Breakeven Inflation (BEI) - is a market based measure of inflation expectations. A sample based on historical bond prices between year 2000 and 2007 is used and adjusted for 3 distortions: i) The mismatch in cash flow structure arising from different bond characteristics. ii) The inflation indexation and bond finance implications (carry). iii) The seasonality in Consumer Price Index (CPI). In the absence of “true” inflation expectations, the benchmark used for the evaluation and comparison of the unadjusted and adjusted BEI series is the survey based, Prospera Money Market Players inflationary expectations, i.e. professional forecasters. The evaluation uses two statistical measures to estimate the errors, the Root Mean Squared Error (RMSE) to estimate the size of the forecast error and the Mean Error (ME) to measure the bias or the tendency for the forecast error to point in a particular direction.
