Interpreting deviations from covered interest parity during the financial market turmoil of 2007–08

This paper investigates the spillover effects of money market turbulence in 2007–08 on the short-term covered interest parity (CIP) condition between the US dollar and the euro through the foreign exchange (FX) swap market. Sharp and persistent deviations from the CIP condition observed during the turmoil are found to be significantly associated with differences in the counterparty risk between European and US financial institutions. Furthermore, evidence is found that US dollar term funding auctions by the ECB, supported by US dollar swap lines with the Federal Reserve, alleviated the level of dislocations, as well as the instability, of the FX swap market.     

When and how US dollar shortages evolved into the full crisis? Evidence from the cross-currency swap market

This paper investigates when and how the US dollar shortages evolved into the full crisis in the cross-currency swap market between major European currencies and the US dollar during the turmoil of 2007-2009, using the dynamic factor model with regime-switching β coefficients of each swap price with respect to the latent common factor. The 1-year market entered the high-β crisis regime soon after the onset of the subprime problem in August 2007. The 10-year market entered that regime following the collapse of Bear Sterns in mid-March 2008. Financial credit spreads have significant predictive power for switches between high and low-β regimes.     

High-frequency information content in end-user foreign exchange order flows

This article considers the impact of foreign exchange (FX) order flows on contemporaneous and future stock market returns using a new database of customer order flows in the euro-dollar exchange rate market as seen by a leading European bank. We do not find clear contemporaneous relationships between FX order flows and stock market changes at high frequencies, but FX flows do appear to have significant power to forecast stock index returns over 1–30 min horizons, after controlling for lagged exchange rate and stock market returns. The effects of order flows from financial customers on future stock market changes are negative, while the effects of corporate orders are positive. The latter results are consistent with the premise that corporate order flows contain dispersed, passively acquired information about fundamentals. Thus, purchases of the dollar by corporate customers represent good news about the state of the US economy. Importantly, though, there also appears to be extra information in corporate flows which is directly relevant to equity prices over and above the impact derived from stock prices reacting to (predicted) exchange rate changes. Our findings suggest that financial customer flows only affect stock prices through their impact on the value of the dollar.     

Global liquidity risk in the foreign exchange market

Using a broad data set of 20 US dollar exchange rates and order flow of institutional investors over 14 years, we construct a measure of global liquidity risk in the foreign exchange (FX) market. Our FX liquidity measure may be seen as the analog of the well-known Pastor–Stambaugh liquidity measure for the US stock market. We show that this measure has reasonable properties, and that there is a strong common component in liquidity across currencies. Finally, we provide evidence that liquidity risk is priced in the cross-section of currency returns, and estimate the liquidity risk premium in the FX market around 4.7 percent per annum.

Global Banks and Synthetic Funding: The Benefits of Foreign Relatives

This paper examines the effect of dislocations in foreign currency (FX) swap markets (“CIP deviations”) on bank lending. Using data from UK banks we show that when the cost of obtaining swap-based funds in a particular foreign currency increases, banks reduce the supply of cross-border credit in that currency. This effect is increasing in the degree of banks' reliance on swap-based FX funding. Access to foreign relatives matters as banks employ internal capital markets to shield their cross-border FX lending supply from the described channel. Partial substitution occurs from banks outside the UK not affected by changes in synthetic funding costs.     

Can channel pattern trading be profitably automated?

Financial markets, such as the global foreign exchange (FX) market, often exhibit trending behaviour. Within such trends, the market level oscillates with changes in market consensus. Continued oscillations of this type result in the formation of wave patterns within the underlying trend known as channels, which are used by technical analysts as trade entry signals. A sample space of such channels has been constructed from a set of US dollar/British pound Spot FX tick data from 1989–1997 using pattern recognition algorithms and the profitability of trading using such patterns has been estimated. A number of attributes of the resulting collection of channels has been subjected to statistical analysis with the aim of classifying patterns that can be traded profitably using a number of simple trading rules. Results of this analysis show that there exist statistically significant links between the channels' attributes and profitability.

FX Dynamics,Limited Participation,and the Forward Bias Anomaly

Standard foreign exchange (FX) models with goods price stickiness and instantaneous asset market adjustments imply FX overshooting ( Dornbusch, 1976 ), which can explain the forward bias anomaly. Lyons (2001) explained the anomaly via limited participation of FX speculators due to Sharpe ratios lower than equity market alternatives, which implies FX undershooting to interest differential shocks. I derive the time‐series implications of overshooting and undershooting for the joint forward/spot FX dynamics in a vector error correction model. I use generalized impulse response analysis ( Pesaran and Shin, 1998 ) to test those implications. All FX studied (pound, deutsch mark, French franc, yen, and Canadian dollar) have dynamics consistent with undershooting during the period from 1975 to 1998.     

Nonparametric testing of the high-frequency efficiency of the 1997 Asian foreign exchange markets

Sherry’s nonparametric pattern tests for neural information processing are used to ascertain if the Asian foreign exchange (FX) rates followed random walks [Sherry, C.J., 1992. The Mathematics of Technical Analysis: Applying Statistics to Trading Stocks, Options and Futuresm Probus, Chicago]. The stationarity and serial independence of the price changes are tested on minute-by-minute data for nine Asian currencies from 1 January 1997 to 30 December 1997. The efficiency of these FX markets before and after the Asian currency ‘regime discontinuity’ are compared. The Thai baht (THB), Malaysian ringgit (MYR), Indonesian rupiah (IDR) and Singapore dollar (SGD) exhibited non-stationary behavior during the entire year, and gave evidence of a trading regime break, while the Phillipines’ peso (PHP), Taiwan dollar (TWD), Japanese yen (JYP) and German deutschmark (DEM) remained stationary, with the US dollar (USD) as numeraire. However, each half-year regime showed stationarity, indicating stable and nonchaotic trading regimes for all currencies, despite their high volatilities, except for the MYR, which exhibited non-stationarity in the second half of 1997. The Thai baht traded nonstationarily in the first half of 1997, but stationarily in the second half. while the TWD reversed that trading pattern. Based on Sherry’s four tests for serial independence, none of the currencies exhibited complete independence. Thus no Asian currency market—including the JYP—exhibited complete efficiency in 1997, in particular when compared with the highly efficient DEM. Remarkably, the PHP remained as efficient as the JYP throughout 1997.     

Using Interest Rate Derivative Prices to Estimate LIBOR-OIS Spread Dynamics and Systemic Funding Liquidity Shock Probabilities

Following the bankruptcy of Lehman Brothers in mid-September 2008, there were severe disruptions in international money markets and banks reportedly faced severe liquidity shocks in particular US dollar funding shortages, prompting central banks around the world to adopt unprecedented policy measures to supply funds to the banks. A better understanding of the forward-looking information content about funding liquidity risk in interest rate derivative prices is therefore necessary to gauge pressures building surrounding systemic liquidity. Using the market prices of the US dollar LIBOR-overnight index swap spread, we estimate the probability of the systemic funding liquidity shock during the crisis period, which deviated from zero on 17 September 2008 to a significant level. This provided an early warning signal of the systemic liquidity shock on 29 September 2008 when the interbank market was totally paralysed.

Network effects in currency internationalisation: Insights from BIS triennial surveys and implications for the renminbi

The dominance of the US dollar in foreign exchange (FX) markets appears to reflect very strong network effects in the use of international currencies. What we observe today is the result of a slow-moving process that has witnessed a switch from the dominance of the pound sterling to the US dollar, perhaps during the interwar period in the early part of the 20th century. This paper presents a discrete choice model of FX trading that explicitly allows for this type of critical transitions in order to understand the dynamics of currency turnover in FX markets. We estimate the model using the Bank for International Settlements' data from triennial surveys of FX markets and also examine the factors that could potentially shift the dynamic path and lead to an earlier critical transition. We then discuss the implications for the renminbi, a budding international currency. If the renminbi were to become a dominant international currency, it would require China to attain a much higher level of financial development and openness. It is important to note that our model does not address the possibility of a gradual weakening of the network effects in FX markets due to, for example, the advancement of trading technologies, which would allow the co-existence of a few equally dominant major currencies.     

美国金融风暴的警示——实现国际收支平衡至关重要

近几年,我国国际收支不平衡的情况日益恶化,国际收支顺差的规模也不断扩大,主要体现在外汇储备的快速增长上;而由于我国的外汇储备投资的资产主要集中在美国国债及其他美元债券上,美国金融危机的爆发使得我国的外汇储备资产价值受到了严峻的挑战,文章指出外汇储备大量投资美元资产不仅使得我们承担了来自美国政府、美元汇率的风险,还使得我们不得不为美国的金融危机买单,而且外需拉动型的经济增长模式也不具有可持续性。因此文章建议从扩大内需、降低贸易顺差、控制外商直接投资、治理热钱流入四个方面,多管齐下切实纠正我国国际收支失衡的现状。     

Credit default swaps and the market for sovereign debt

In this paper, we analyze the determinants and effects of credit default swap (CDS) trading initiation in the sovereign bond market. CDS trading initiation is associated with a 30–150 basis point reduction in sovereign bond yields, with greater yield reductions accruing to higher default risk economies. For countries with high default risk, rated B or lower by Standard and Poor’s, CDS initiation is also associated with significant price efficiency benefits in the underlying market. CDS trading initiation is more likely following increases in local equity index volatility, index spreads for regional and global CDS markets, or depreciation of the local currency relative to the US dollar, and decreases in a country’s ability to service foreign debt. Our results are robust to selection bias controls based on these factors.     

What explains global exchange rate movements during the financial crisis?

A striking and unexpected feature of the financial crisis has been the sharp appreciation of the US dollar against virtually all currencies globally. The paper finds that negative US-specific macroeconomic shocks during the crisis have triggered a significant strengthening of the US dollar, rather than a weakening. Macroeconomic fundamentals and financial exposure of individual countries are found to have played a key role in the transmission process of US shocks: in particular countries with low FX reserves, weak current account positions and high direct financial exposure vis-à-vis the United States have experienced substantially larger currency depreciations during the crisis overall, and to US shocks in particular.     

Contagion inside the credit default swaps market: The case of the GM and Ford crisis in 2005

We study the General Motors (GM) and Ford crisis in 2005 in order to determine if the credit default swap (CDS) market is subject to contagion effects. Has the crisis spread to the whole (CDS) market? To answer this question, we study the correlations between CDS premia, by using a sample of 226 CDSs on major US and European firms. We do evidence a significant rise in correlations during the crisis episode, but little “shift-contagion” as defined by Forbes and Rigobon (2002). When using dynamic measures of correlations (EWMA and DCC-GARCH), we also show that correlations significantly increased during the crisis, especially in the first week.
