Measuring and assessing the effects and extent of international bond market integration

We review briefly the literature on international financial integration, especially as it pertains to bond market integration. This contextualizes the review we than provide of a number of papers contained in a special issue of this Journal. © 2005 Elsevier B.V. All rights reserved.

The side effects of quantitative easing:evidence from the UK bond market

We examine the returns to UK government bonds before, during and between the phases of quantitative easing to identify the side effects for the market itself. We show that the onset of QE led to a sustained reduction in the costs of trading and removed some return regularities. However, controlling for a wide range of market activity, including issuance and QE announcements, we find evidence that investors could have earned excess returns after costs by trading in response to the purchase auction calendar. Drawing on economic theory, we explore the implications of these findings for both the efficiency of the market and the costs of government debt management in both the short and long run.

Secondary market pricing behaviour around UK bond auctions

Using an event study approach, this article reports evidence that the UK Treasury bond market displayed anomalous pricing behaviour in the secondary market both immediately before and after auctions of seasoned bonds. Using a benchmark return derived from the behaviour of the underlying yield curve, the market offered statistically and economically significant excess returns, around the auctions held between 1992 and 2004. A cross-sectional analysis of the cumulative excess returns shows that the excess demand at the auctions is a key determinant of this excess return.

Volatility transmission between stock and bond markets

A two-factor no-arbitrage model is used to provide a theoretical link between stock and bond market volatility. While this model suggests that short-term interest rate volatility may, at least in part, drive both stock and bond market volatility, the empirical evidence suggests that past bond market volatility affects both markets and feeds back into short-term yield volatility. The empirical modelling goes on to examine the (time-varying) correlation structure between volatility in the stock and bond markets and finds that the sign of this correlation has reversed over the last 20 years. This has important implications far portfolio selection in financial markets. © 2005 Elsevier B.V. All rights reserved.

Econometrics of yield spreads in the money market:a note

The literature on bond markets and interest rates has focused largely on the term structure of interest rates, specifically, on the so-called expectations hypothesis. At the same time, little is known about the nature of the spread of the interest rates in the money market beyond the fact that such spreads are generally unstable. However, with the evolution of complex financial instruments, it has become imperative to identify the time series process that can help one accurately forecast such spreads into the future. This article explores the nature of the time series process underlying the spread between three-month and one-year US rates, and concludes that the movements in this spread over time is best captured by a GARCH(1,1) process. It also suggests the use of a relatively long term measure of interest rate volatility as an explanatory variable. This exercise has gained added importance in view of the revelation that GARCH based estimates of option prices consistently outperform the corresponding estimates based on the stylized Black-Scholes algorithm.
