The impact of monetary policy candidness on Australian financial markets

In January 1990, the Reserve Bank of Australia (RBA) changed from a covert disclosure policy to an overt disclosure policy. Using a sample from January 1986 to September 2001, this paper examines the reaction of Australian financial markets to rate target changes within each of these disclosure regimes. We find significantly different announcement day responses between the two disclosure regimes for both short-term and long-term treasury securities, and equity indices. Overall, the results indicate that when monetary policy is more transparent, the market reaction is less pronounced and, therefore, we conclude that fuller disclosure of monetary policy allows investors to more optimally manage their portfolios.     

The role of political uncertainty in Australian financial markets

Within the developed world, recent Australian political history is uniquely turbulent. This situation invokes indecision regarding investment decisions in both the real economy and the financial markets. This paper explores the relationship between uncertainty in Australian federal election polling and resulting financial market uncertainty. Empirical evidence suggests that increasing (decreasing) levels of uncertainty around the election result induce higher (lower) levels of uncertainty in financial markets. The effect is more pronounced as polling day approaches. Industry‐level analysis suggests that the base materials sector is most significantly affected by election uncertainty in Australia.     

The impact of the euro on Europe's financial markets

This paper presents an overview of the impact of the introduction of the euro on Europe's financial structure over the first four years since the start of EMU. It analyzes changes in money markets, bond markets, equity markets and foreign exchange markets. Euro's role in originating or catalyzing trends has been uneven across the spectrum of financial markets. From the supply side, banks and investors in fixed income markets have become more focused on the characteristics of individual borrowers rather than the nationality of the issuer and have built up expertise to evaluate credit risk. European equity markets have also been affected by the enhanced ability of investors to build strategies with a pan‐European perspective as prices increasingly reflected risk factors specific to industrial sectors rather than individual countries. On the borrower side, EMU has increased the attractiveness of market‐based financing methods by allowing debt issuers to tap institutional portfolios across the euro area. Lower barriers to cross‐border financial transactions have also increased the contestability of the market for financial services, be it at the wholesale or the retail level. The introduction of the euro has also highlighted the shortcomings of existing institutional structures and areas where excessive focus on narrowly defined interests may stand in the way of realizing the full potential benefits from the new environment. Diverging legal and institutional infrastructures and market practices can impede further financial market development and deepening. Hence, the euro has put a premium on cooperation between national authorities and institution as a means of achieving a more harmonized financial environment. The impact of EMU on depth in foreign exchange markets has been less clear‐cut, as volatility, spreads, trading volumes and liquidity appear not to have changed in a substantial way. Overall, it seems that the new currency has made some progress towards the goal of becoming a currency of international stature that would rival that of the US dollar. However, a number of the necessary next steps towards achieving this goal are also among the trickiest to implement.     

The impact of sovereign rating actions on bank ratings in emerging markets

This paper analyses the effects of sovereign rating actions on the credit ratings of banks in emerging markets, using a sample from three global rating agencies across 54 countries for 1999–2009. Despite widespread attention to sovereign ratings and bank ratings, no previous study has investigated the link in this manner. We find that sovereign rating upgrades (downgrades) have strong effects on bank rating upgrades (downgrades). The impact of sovereign watch status on bank rating actions is much weaker and often insignificant. The sensitivity of banks’ ratings to sovereign rating actions is affected by the countries’ economic and financial freedom and by macroeconomic conditions. Ratings of banks with different ownership structures are all influenced strongly by the sovereign rating, with some variation depending on the countries’ characteristics. Emerging market bank ratings are less likely to follow sovereign rating downgrades during the recent financial crisis period.     

The impact of the Russian-Ukrainian war on global financial markets

On February 24, 2022, Russia invaded the Ukraine. In this paper, we analyze the response of European and global stock markets alongside a representative sample of commodities. We compare the war response against the recent Covid-19 pandemic and the not-too-distant 2008 global financial crisis. Applying a Markov-switching HAR model on volatility proxies, estimates are made of synchronization, duration and intensity measures for each event. In broad terms, stock markets and commodities respond most rapidly to the Russian invasion; and post-invasion crisis intensity is noticeably smaller compared to both the Covid-19 and the GFC. Wheat and nickel are the most affected commodities due to the prominent exporter status of the two countries.     

The impact of target firm financial distress in Australian takeovers

Of the motives that have been advanced to explain corporate acquisitions, the least explored is the acquisition of a target experiencing financial distress. This study addresses this void by examining whether target firm financial distress is related to takeover: attitude, premiums, payment method, competition and outcome. Despite inconsistent findings across our distress measures the tenor of the results suggest that distressed targets receive higher premiums and are less likely to be offered cash consideration. Additionally, takeover completion is lower and takeover competition higher for targets in financial distress. Financial distress does not influence whether a takeover is hostile or friendly.     

The impact of rights issues of convertible debt in Australian markets

Australian convertible debt issues are rights issues of non-callable securities and are issued in a market characterised by thin trading, significant institutional investor participation rates and a high number of resource firms. However, this study documents a significant negative announcement effect for rights issues of convertible debt, similar to international evidence. An analysis of the determinants of the announcement effect supports variants of the information asymmetry and agency cost hypotheses. The results do not support the convertible debt models of Kim [Kim, Y., 1990. Informative conversion ratios, a signalling approach. Journal of Financial and Quantitative Analysis 25, 229–243], Brennan and Kraus [Brennan, M., Kraus, A., 1987. Efficient financing under asymmetric information. Journal of Finance 42, 1225–1243], Green [Green, R.C., 1984. Investment incentives, debt and warrants. Journal of Financial Economics 13, 115–136] but some support is found for Stein's [Stein, J., 1992. Convertible bonds as backdoor equity financing. Journal of Financial Economics 32, 3–22], convertible debt model and Mayers [Mayers, D., 1998. Why firms issue convertible bonds: the matching of financial and real investment options. Journal of Financial Economics 47, 83–102], sequential financing model. However, support is found for Brous and Kini [Brous, P.A., Kini, O., 1994. The valuation effects of equity issues and the level of institutional ownership: evidence from analysts’ earnings forecasts. Financial Management 23, 33–46], equity issue based external monitoring model and Eckbo and Masulis [Eckbo, B., Masulis, R., 1992. Adverse selection and the rights offer paradox. Journal of Financial Economics 32, 292–332], rights issue adverse selection model.     

The impact of terrorism on financial markets: An empirical study

The main focus of this paper is to study empirically the impact of terrorism on the behavior of stock, bond and commodity markets. We consider terrorist events that took place in 25 countries over an 11-year time period and implement our analysis using different methods: an event-study approach, a non-parametric methodology, and a filtered GARCH-EVT approach. In addition, we compare the effect of terrorist attacks on financial markets with the impact of other extreme events such as financial crashes and natural catastrophes. The results of our analysis show that a non-parametric approach is the most appropriate method among the three for analyzing the impact of terrorism on financial markets. We demonstrate the robustness of this method when interest rates, equity market integration, spillover and contemporaneous effects are controlled. We show how the results of this approach can be used for investors’ portfolio diversification strategies against terrorism risk.     

Effect of credit rating changes on Australian stock returns

We study the impact credit rating revisions have on stock returns of Australian firms rated by Standard & Poor's and Moody's. Our evidence is consistent with that documented in the USA showing that only downgrades contain price‐relevant information. The reaction is most significant when the downgrade: (i) is unanticipated; (ii) is for an unregulated firm; and (iii) reduces the firm's rating by more than one category.     

ESG in credit ratings and the impact on financial markets

This study examines environment, social, governance (ESG) consideration in rating reports published by credit rating agencies. 3,719 Moody's credit rating reports between 2004 and 2015 are examined and the ESG consideration is analyzed using a latent dirichlet allocation (LDA) approach. We further analyze the stock returns and credit default swap (CDS) spread changes to check whether ESG consideration has an effect on the capital market reactions. We find a small but present consideration of ESG in rating decisions. Within ESG, corporate governance plays the most important role. Moreover, the results reveal that ESG consideration is a significant determinant in the stock return and CDS spread around the rating announcement. We find that all ESG criteria are important for equity and debt investors.     

Announcements and revisions of Australian macroeconomic data and their news content for Australian financial markets

This paper investigates the responsiveness of nine Australian financial markets to announcements and revisions of balance on current account and GDP data. We find that current account announcements have a significant effect. Globally, the whole set of revisions are not significant but some individual revisions are statistically significant. When we partition announcements and revisions into good news and bad news we find that with respect to announcements only bad news about the current account has a significant impact. While the global set of revisions are not significant, an increased number of isolated revisions are significant. However, our general conclusion as to the overall lack of significance of the revisions data still holds true.     

The role of hormones in financial markets

Steroid hormones, such as testosterone, have been shown to affect risk preferences in financial traders with high levels leading to excessive risk-taking. Hormone levels, in turn, are affected by trading outcomes as well as by gender - males are more sensitive to stimuli than females. We develop a model to investigate the effects of hormones on financial market stability and trader performance. An increase in the proportion of female traders does not necessarily make markets less volatile; however, it reduces the occurrence of market crashes. Male traders on average under-perform females, although the best performing individuals are more likely to be male.     

The impact of sovereign rating changes on the activity of European banks

We verify the effects of sovereign rating revisions on the activity of European banks, in terms of their regulatory capital ratio, profitability, liquidity, and lending supply. First, we find that a sovereign downgrade has a significant impact, primarily on capital ratios and lending supply. In contrast, upgrades do not have a significant impact, indicating an asymmetric effect of sovereign rating changes. Second, we find that three transmission channels (assets channel, funding channel, and rating channel) explain a relevant part of the impact of a sovereign downgrade. Finally, we find strong evidence that the rating-based regulation affects all measures of the activity of domestic banks, causing negative externalities for financial institutions. Our results hold also controlling for sovereign risk, estimating a GMM system, and employing an instrumental variable approach.     

The information content of issuer rating changes: Evidence for the G7 stock markets

We study the firm-specific and intra-industry stock market effects of issuer credit rating changes and negative watch list placements for the G7 countries. We show that both the information content and the information transfer effects of these rating signals differ considerably in terms of magnitude and in terms of direction across the G7 countries. In particular, conditional on the type of rating change we find significant contagion effects for the US, the UK and Italy, but not for the other G7 countries. Moreover, we show that in some countries abnormal industry portfolio returns associated with rating downgrades and negative watch list signals tend to be more negative for more concentrated and more heavily levered industries. Overall, our results shed new light on country-specific differences in the relevance of credit ratings as risk indicators from an equity investor's perspective, and they may also be of interest to both risk managers and financial market supervisors striving to develop more accurate credit risk models and to better assess the systemic relevance of credit ratings.     

The impact of COVID-19 pandemic on transmission of monetary policy to financial markets

This study uses event-study methodology to estimate the impact of the COVID-19 pandemic on the transmission of monetary policy to financial markets, based on a sample of 37 countries with severe pandemics. Financial markets include government bond, stock, exchange rate and credit default swap markets. The results suggest that the emergence of pandemic has weakened the transmission of monetary policy to financial markets to a more significant degree. During our sample period following the outbreak of pandemic, neither conventional nor unconventional monetary policies have significant effects on all four of the financial markets. Of course, the unconventional monetary policies are slightly more effective as they can affect the stock and exchange rate markets to some extent. Therefore, in the post-pandemic period, if the monetary policy is used to stimulate financial markets, stronger policy adjustments, or other macro policies such as fiscal policies, may be needed to achieve the desired effect     

The war on terror and its impact on the long-term volatility of financial markets

In this article, we analyze how the U.S.' declaration of the war on terror and the subsequent invasion of Iraq has impacted long-term volatility of stock markets around the world. In doing so, we utilize two statistical techniques: wavelet-based variance analysis and a semi-parametric fractional autoregressive (SEMIFARIMA) model. Our sample comprises stock and commodity indices worldwide for the sample period January 2000-June 2006. Specifically, we consider four geographic regions: the Americas, Africa/Middle East, Europe, and Asia/Pacific. We conclude that political instability in the Middle East had its greatest impact on the volatility of financial markets around the beginning of the Iraq war, and it mostly hit developed markets (e.g., United States, United Kingdom, and Japan). Thereafter, for most sampled indices, volatility has exhibited a decreasing trend to reach eventually levels even lower than that observed at the beginning of our sample. An exception is Egypt's CMA and the Dow Jones AIG all commodities. We think that the latest political conflicts in the Middle East and their impact on the price of oil may be the most likely driving force of such volatility in those two indices. Specifically, among Egypt's main export products are petroleum and petroleum products.     

Disentangling the impact of economic and health crises on financial markets

This paper explores the impact of different crises on the informational efficiency of financial assets. The study covers stock markets indices (ASX200, DAX30, EuroStoxx50, S&P500 and Nikkei), commodities (gold and oil) and volatility (VIX). The study analyzes, using a rolling window method, the long memory profile and the multifractality of the time series by means of the DFA and generalized Hurst exponents. This dynamic analysis is important as it uncovers the time-varying behavior of returns characteristics, affecting the investment decisions and trading strategies at different moments of time. The paper extends the current literature on informational efficiency, providing evidence of the distinct impact on the long memory and on the multifractality of the time series, depending on the nature of the crisis and the market. The results could be of interest for investors as well as for academics, regarding the hedging limits of the models during calm or turbulent times.     

The financial crisis of 2008 in fixed-income markets

We explore how a relatively small amount of heterogeneous securities created turmoil in financial markets in much of the world in 2007 and 2008. The drivers of the financial turmoil and the Financial Crisis of 2008 were heterogeneous securities that were hard to value. These securities created concerns about counterparty risk and ultimately created substantial uncertainty. The problems spread in ways that were hard to see in advance. The run on prime money market funds in September 2008 and the effects on commercial paper were an important aspect of the crisis itself and are discussed in some detail.     

Information provision in financial markets

We set up a rational expectations model in which investors trade a risky asset based on a private signal they receive about the quality of the asset, and a public signal that represents a noisy aggregation of the private signals of all investors. Our model allows us to examine what happens to market performance (market depth, price efficiency, volume of trade, and expected welfare) when regulators can induce improved information provision in one of two ways. Regulations can be designed that either provide investors with more accurate information by improving the quality of prior information, or that enhance the transparency of the market by improving the quality of the public signal. In our rational expectations equilibrium, improving the quality of the public signal can be interpreted as a way of providing information about the anticipations and trading motives of all market participants. We find that both alternatives improve market depth. However, in the limit, we show that improving the precision of prior information is a more efficient way to do so. More accurate prior information decreases asymmetric information problems and consequently reduces the informativeness of prices, while a more accurate public signal increases price informativeness. The volume of trade is independent of the quality of prior information and is increasing in the quality of the public signal. Finally, expected welfare can sometimes fall as prior information or the public signal become more precise.
