The fact that the shape of the yield curve changes over time suggests that monetary policy interest rate changes are not the only factor affecting interest rates Three theories have been advanced to explain the shape of the yield curve –Expectations theory –Market segmentation theory –Liquidity premium theory

28. Copyright  2007 McGraw-Hill Australia Pty Ltd PPTs t/a McGrath’s Financial Institutions, Instruments and Markets 5e by Viney Slides prepared by Anthony Stanger 13-28 Expectations theory The current short-term interest rate and expectations about future short-term interest rates are used to explain the shape and changes in shape of the yield curve Longer-term rates will be equal to the average of the short-term rates expected over the period The theory is based on assumptions, e.g. –Large number of investors with reasonably homogenous expectations –No transactions costs and no impediments to interest rates moving to their competitive equilibrium levels –Investors aim to maximise returns and view all bonds as perfect substitutes regardless of term to maturity

29. Copyright  2007 McGraw-Hill Australia Pty Ltd PPTs t/a McGrath’s Financial Institutions, Instruments and Markets 5e by Viney Slides prepared by Anthony Stanger 13-29 Expectations theory Example: The rate on a one-year instrument is 7% per annum.

30. Copyright  2007 McGraw-Hill Australia Pty Ltd PPTs t/a McGrath’s Financial Institutions, Instruments and Markets 5e by Viney Slides prepared by Anthony Stanger 13-30 Expectations theory Explanation for the shape of yield curves –Inverse yield curve  Will result if the market expects future short-term rates to be lower than current short-term rates –Normal yield curve  Will result from expectations that future short-term rates will be higher than current short-term rates –Humped yield curve  Investors expect short-term rates to rise in the future but to fall in subsequent periods

31. Copyright  2007 McGraw-Hill Australia Pty Ltd PPTs t/a McGrath’s Financial Institutions, Instruments and Markets 5e by Viney Slides prepared by Anthony Stanger 13-31 Segmented markets theory Assumes that securities in different maturity ranges are viewed by market participants as imperfect substitutes (i.e. investors will operate within some preferred maturity range) –Rejects two assumptions of the expectations theory –Preferences of participants are motivated by reducing the risk of their portfolios, i.e. minimising exposure to fluctuations in prices and yields The shape and slope of the yield curve are determined by the relative demand and supply of securities along the maturity spectrum

Copyright  2007 McGraw-Hill Australia Pty Ltd PPTs t/a McGrath’s Financial Institutions, Instruments and Markets 5e by Viney Slides prepared by Anthony Stanger 13-34 Segmented markets theory If the central bank increases the average maturity of bonds by purchasing short-term bonds and selling long-term bonds –Segmented markets theory suggests  Short-term yields decrease and long-term yields increase  Although financial system liquidity is unchanged, economic activity is affected because areas of expenditure sensitive to Short-term interest rates will expand Long-term interest rates will contract –Expectations theory suggests  No effect on expectations about future short-term interest rates, and therefore no effect on the economy

35. Copyright  2007 McGraw-Hill Australia Pty Ltd PPTs t/a McGrath’s Financial Institutions, Instruments and Markets 5e by Viney Slides prepared by Anthony Stanger 13-35 Expectations approach versus segmented markets approach The emphasis of the segmented markets theory on risk management denies the existence of investors seeking –Arbitrage opportunities  Without their participation, the extreme segmentation theory would facilitate discontinuities in the yield curve –Speculative profit  Speculators’ trading actions are dictated by expectations
