英国利率市场化回顾及其对金融业改革的影响

利率市场化是指金融机构在货币市场经营融资的利率由市场供求来决定。它包括利率决定、利率传导、利率结构和利率管理的市场化。文章介绍了英国利率市场化改革的背景、实施过程及其对英国经济金融运行与货币政策调控产生的积极影响。指出利率市场化改革后,英国的宏观经济环境趋于稳定,社会融资结构逐渐向直接融资为主转变;利率市场化为其后旨在提高英国金融业竞争力的金融市场改革铺平了道路。     

Analyzing interest rate risk: Stochastic volatility in the term structure of government bond yields

We propose a Nelson–Siegel type interest rate term structure model where the underlying yield factors follow autoregressive processes with stochastic volatility. The factor volatilities parsimoniously capture risk inherent to the term structure and are associated with the time-varying uncertainty of the yield curve’s level, slope and curvature. Estimating the model based on US government bond yields applying Markov chain Monte Carlo techniques we find that the factor volatilities follow highly persistent processes. We show that yield factors and factor volatilities are closely related to macroeconomic state variables as well as the conditional variances thereof.     

Managing the risk of loan prepayments and the optimal structure of short term lending rates

Loan pricing is an extremely important aspect of bank operations because loans are typically over two-thirds of bank assets. Many researchers have analyzed the theoretical and empirical impact of how different factors should and do affect fixed rate loan rates and loan prepayments. However, a theoretical decision making model for maximizing expected profit in a declining rate environment has not been developed. After describing the conditions for the optimal loan rate, we develop numerical solutions for it under varying conditions. The varying conditions include the trend in interest rates, volatility of interest rates, and loan maturity. We thank Yen Low and Hamed Bagherpour for their assistance.     

New No-arbitrage Conditions and the Term Structure of Interest Rate Futures

Interest rate futures are basic securities and at the same time highly liquid traded objects. Despite this observation, most models of the term structure of interest rate assume forward rates as primary elements. The processes of futures prices are therefore endogenously determined in these models. In addition, in these models hedging strategies are based on forward and/or spot contracts and only to a limited extent on futures contracts. Inspired by the market model approach of forward rates by Miltersen, Sandmann, and Sondermann (J Finance 52(1); 409–430, 1997), the starting point of this paper is a model of futures prices. Using, as the input to the model, the prices of futures on interest related assets new no-arbitrage restrictions on the volatility structure are derived. Moreover, these restrictions turn out to prevent an application of a market model based on futures prices.     

Macroeconomic releases and the interest rate term structure

We extract two systematic economic factors from a wide array of noisy and sparsely observed macroeconomic releases, and link the dynamics and market prices of the two factors to the interest rate term structure. The two factors predict 77.9–82.1% of the daily variation in LIBOR and swap rates from one month to 10 years. Shocks on inflation-related releases have large, positive impacts on interest rates of all maturities, leading to parallel shifts of the yield curve, but shocks on output-related releases have larger impacts on the short rate than on the long rate, thus generating a slope effect.     

Signalling with official interest rates: the case of the German discount and lombard rate

A major characteristic of the operating procedure of the European Central Bank (ECB) is its reliance on standing facilities. It is intended that the official rates on those facilities also serve the function of signalling. The case of Germany, where the Bundesbank followed a similar signalling strategy, is analysed. In particular the paper investigates whether announcements of official interest rates provide information not already contained in other policy measures and whether the resulting revisions of expectations are efficient. Significant differences are found between signalling in the case of increasing and decreasing interest rates.     

The anticipated and concurring effects of the EMU: exchange rate volatility, institutions and growth

Reduced exchange rate volatility and higher and less heterogeneous quality of institutional rules and macroeconomic policies are two of the main (anticipated and concurring) effects expected from a currency union.In this paper, we measure the magnitude of these two effects for the Eurozone countries looking at real effective exchange rates (REER) and at different indicators of quality of institutional rules and macroeconomic policies (QIRMP). We find that the first effect is much stronger than the second when we compare relative changes for Eurozone countries and the rest of the world in the relevant period.We further evaluate the impact of both effects on economic growth on a larger sample of countries. Our findings show that both have significant impact on levels (more robust) and on rates of growth (weaker) of per capita GDP.     

Accounting quality,information risk and the term structure of implied volatility around earnings announcements

We examine the association between accounting quality, which is used as a proxy for firm information risk, and the behavior of the term structure of implied option volatility around earnings announcements. By employing a large sample of US firms having options traded on their equity during 1996–2010, we find that lower (higher) accounting quality is significantly associated with stronger (weaker) changes in the steepness of the term structure of implied volatility curve around quarterly earnings announcements. This finding (which is robust to controls for business-stemming uncertainty regarding future firm performance) is consistent with a stronger differential of short vs. long-term uncertainty for higher information risk firms, indicating greater uncertainty on the future economic performance of poorer vs. stronger accounting quality firms. We also establish the trading implications of these findings by demonstrating a (profitable in-sample) self-financed option trading strategy that is based on the quality of the accounting information released on earnings announcement days.     

Calibration of Gaussian heath, Jarrow and Morton and random field interest rate term structure models

We show how the recently introduced Gaussian random field interest rate term structure models can be calibrated accurately and quickly to market caps and swaptions prices. We show how the calibrated random field model can be approximated arbitrarily closely with a multi-factor Gaussian Heath, Jarrow and Morton model. We argue that the Gaussian random field model is easier to calibrate and can be used as an indirect way to calibrate multi-factor Gaussian Heath, Jarrow and Morton interest rate models.This work was carried out when the author was at the Financial Options Research Centre, Warwick Business School, University of Warwick.

Banks’ exposure to interest rate risk, their earnings from term transformation, and the dynamics of the term structure

We use a unique dataset of German banks’ exposure to interest rate risk to derive the following statements about their exposure to this risk and their earnings from term transformation. The systematic factor for the exposure to interest rate risk moves in sync with the shape of the term structure. At bank level, however, the time variation of the exposure is largely determined by idiosyncratic effects. Over time, changes in earnings from term transformation have a large impact on interest income. Across banks, however, the earnings from term transformation do not seem to be a decisive factor for the interest margin.     

The impact of the stapled security structure on the quality of financial disclosure: Evidence from Australian Real Estate Investment Trusts and Listed Infrastructure Funds

This paper is the first study to explore whether the stapled structure influences firms’ activities in earnings management (EM). Trusts and firms under stapled securities are exposed to various managerial opportunities and activities that can provide the flexibility of using EM approaches. Therefore, the stapled structure is expected to induce increased EM behavior and signal a lower level of financial disclosure quality than the unstapled structure. This empirical research analyzes a panel dataset that contains information of Australian REITs (A-REITs) and Listed Infrastructure Funds (LIFs) from the year of 2000–2017. Evidence shows that stapled A-REITs and LIFs use a greater magnitude of EM approaches than unstapled entities. The results imply that the stapled security structure may signal lower-quality of financial disclosure for firms than the unstapled security structure. This study provides additional insight into the understanding of how the security structure may impact firms’ financial disclosure behavior.
