The Link between FX Swaps and Currency Strength during the Credit Crisis of 2007-2008

This note analyses the impact of the global credit crisis on the FX swap market and discusses its potential implications. The turbulence in money markets has spilled over to FX swap markets amid a reappraisal of counterparty risks during the recent financial turmoil. We examine the situations of six currencies including the euro, the British pound, the Australian dollar, the Japanese yen, the Hong Kong dollar and the Singapore dollar. We find that (i) the risk premiums have indeed gone in tandem with the spreads of money market rates over their corresponding overnight index swaps across the economies, a popular measure of potential banking insolvency; and (ii) the risk premiums bear a negative relationship with the strength of the spot rates of the respective currencies, which is consistent with the increased pressure in the swap markets.

Share Price Disparity in Chinese Stock Markets

The presence of price disparity between A- and H- shares suggests that the two markets are segmented and thus allocation of capital is inefficient. In this paper, we attempt to identify the factors contributing to the price disparity, with a view to helping policymakers find solutions to the problem. Our results suggest that the disparity is caused by a combination of micro and macro factors. The fact that some of these factors are found to have played a crucial role in determining the disparity implies that reforms that can remove or reduce the segmentation can potentially bring considerable benefits by improving price discovery and market efficiency.

Impact of Financial Liberalisation on Stock Market Liquidity: Experience of China

This paper assesses the impact of the recent financial reforms in China. Following the countrys accession to the World Trade Organization, financial liberalisation has picked up considerable momentum. Measures introduced encompass deregulation in the banking sector and refinements in various financial markets, as well as allowing more freedom for Chinese and foreign investors to participate and interact domestically and overseas. Compared to other studies on financial liberalisation, this study focuses on a relatively narrower aspect of financial reforms namely, the impact on stock market liquidity. Using a panel data set drawn from the Shanghai stock market, we find a positive and significant liquidity impact associated with the recent round of measures, which reflects not only an improvement in capital allocation efficiency in Chinas equity market but, from a financial stability point of view, also a reduction in its vulnerability. The finding also provides evidence on one of the important channels in which financial liberalisation can be transformed into economic growth over time.

Gauging the Safehavenness of Currencies

This study assesses the ‘safehavenness’ of a number of currencies with a view to providing a better understanding of how capital flows tend to react to sharp increases in global risk aversion during periods of financial crisis. It focuses on how currencies are perceived by dollar-based international investors or, more specifically, whether they are seen as safe-haven or risky currencies. To assess the ‘safehavenness’ of a currency, we use a measure of risk reversal, which is the price difference between a call and put option of a currency. This measures how disproportionately market participants are willing to pay to hedge against appreciation or depreciation of the currency. The relationship between the risk reversal of a currency and global risk aversion is estimated by means of both parametric and non-parametric regressions which allow us to capture the relationship in times of extreme adversity, i.e., tail risk. Our empirical results suggest that the Japanese yen and, to a lesser extent, the Hong Kong dollar are the only safe haven currencies under stressful conditions out of 34 currencies vis-a-vis the US dollar.

Risk-adjusted Covered Interest Parity: Theory and Evidence

We extend the theory of covered interest parity (CIP), aligning the different risks involved in uncollateralized money market transactions and collateralized foreign exchange (FX) swap transactions, which underscore CIP deviations in times of elevated uncertainty. We postulate that the swap dealer behaves as if he tries to filter out the counterparty risk embedded in money market rates in pricing FX swaps. Our results suggest that he does so not only during turbulent times but also under normal market conditions. The extended theory also uncovers a simple way to disentangle counterparty and liquidity risk premiums embedded in money market rates.

How Might Sovereign Bond Yields in Asia Pacific React to US Monetary Normalisation under Turbulent Market Conditions

This paper examines the potential impact of US monetary normalisation on sovereign bond yields in Asia Pacific. We apply the quantile vector autoregressive model with principal component analysis to the assessment of tail risk of sovereign debt, which may not be detectable using traditional OLS-based analysis. Our empirical evidence suggests that US Treasury bond yields can have a significant impact on sovereign bond yields in the region, an important channel through which monetary normalisation by the Fed can affect Asia-Pacific economies. Increases in sovereign bond yields will not only compromise the ability of the sovereigns in the region to service their debt but also translate into higher costs of borrowing for the rest of the economy. The results show how much the outsized impact could potentially be if US monetary normalisation somehow turns out to be much more disorderly than expected.

Safehavenness of currencies

ABSTRACT This study assesses the ‘safehavenness’ of a number of currencies with a view to providing a better understanding of how capital flow tends to react to a sharp increase in global risk aversion in turbulent times. It focuses on how the currencies are perceived by international investors or, more specifically, whether they are seen as safe-haven or risky currencies. To assess the safehavenness of the currency, we use risk reversal, which is the price difference between the call and put options of a currency, as it reflects how disproportionately market participants are willing to pay to hedge against its appreciation or depreciation. The relationship between the risk reversal of the currency and global risk aversion is estimated by means of parametric and non-parametric regressions that allow us to capture currency behaviour in times of extreme adversity, that is, the tail risk. Our empirical results found the Japanese yen and, to a lesser extent, the Hong Kong dollar to be the only safe havens under stressful conditions among the 34 currencies vis-à-vis the US dollar.

Chapter 4 The Link between FX Swaps and Currency Strength during the Credit Crisis of 2007–2008

This chapter analyses the impact of the global credit crisis on the money market and discusses its potential implications. The turbulence in money markets has spilled over to foreign exchange (FX)-swap markets amid a reappraisal of counterparty risks during the recent financial turmoil. We examine the situations of six currencies: the euro, the British pound, the Australian dollar, the Japanese yen, the Hong Kong dollar, and the Singapore dollar. We find that (i) the risk premiums have indeed gone in tandem with the spreads of money market rates over their corresponding overnight index swaps across the economies, a popular measure of potential banking insolvency; and (ii) the risk premiums bear a negative relationship with the strength of the spot rates of the respective currencies, which is consistent with the increased pressure in the money and swap markets.
