2010年1月国际金融市场运行综述

2010年1月,受投资者避险情绪升温影响,美元对主要货币总体走强,具体来看,美元对欧元、英镑走强,对日元走弱。因各主要经济体中央银行继续保持宽松的货币政策,美元、欧元、日元短期利率微降,而英镑短期利率因意外强劲的通胀数据而出现微升。主要国家中长期国债收益率总体下降;全球主要股指冲高后大幅回落。     

Risk appetite,carry trade and exchange rates

Using exchange rate data from four different countries (time zones), we examine the relationship between the Yen exchange rate against major currencies (i.e. USD/JPY, EUR/JPY, GBP/JPY, AUD/JPY and NZD/JPY) and measures of risk appetite (i.e. the S&P500 index, Dow Jones Industrial Average index and the VIX index). Our results show that the equity indexes, especially the Dow Jones Industrial Average, play a more important role in the determination of the Yen cross rates than VIX. The popular carry-trade currencies, i.e. NZD/JPY, AUD/JPY and GBP/JPY, are more affected by the US equity market than USD/JPY and EUR/JPY. While the long-term relationships are consistent across the four different time zones, the short-term dynamics are different. We find that the response of NZD/JPY, AUD/JPY and GBP/JPY to changes in the US stock market is much greater in the New Zealand and Australian zones than in the UK or US. Although the short-term relationship between exchange rates and the equity index is quite strong, the error correction speed is very sluggish. We also find evidence of asymmetric adjustment in the response of exchange rates to changes in global risk aversion. Carry trade currencies tend to appreciate gradually when conditions are favorable but fall sharply when market risk increases.

Riding the swaption curve

We conduct an empirical analysis of the term structure in the volatility risk premium in the fixed income market by constructing long-short combinations of two at-the-money straddles for the four major swaption markets (USD, JPY, EUR and GBP). Our findings are consistent with a concave, upward-sloping maturity structure for all markets, with the largest negative premium for the shortest term maturity. The fact that both delta–vega and delta–gamma neutral straddle combinations earn positive returns that seem uncorrelated suggests that the term structure is affected by both jump risk and volatility risk. The results seem robust for macroeconomic announcements and the specific model choice to estimate the risk exposures for hedging.

FX volatility forecasts and the informational content of market data for volatility

The paper examines the medium-term forecasting ability of several alternative models of currency volatility. The data period covers more than eight years of daily observations, January 1991 to March 1999, for the spot exchange rate, 1- and 3-month volatility of the DEM/JPY, GBP/DEM, GBP/USD, USD/CHF, USD/DEM and USD/JPY. Comparing with the results of ‘pure’ time series models, the reported work investigates whether market implied volatility data can add value in terms of medium-term forecasting accuracy. This is done using data directly available from the marketplace in order to avoid the potential biases arising from ‘backing out’ volatility from a specific option pricing model. On the basis of the over 34 000 out-of-sample forecasts produced, evidence tends to indicate that, although no single volatility model emerges as an overall winner in terms of forecasting accuracy, the ‘mixed’ models incorporating market data for currency volatility perform best most of the time.

Exchange rate determination and inter-market order flow effects

The dependence of foreign exchange rates on order flow is investigated for four major exchange rate pairs, EUR/USD, EUR/GBP, GBP/USD and USD/JPY, across sampling frequencies ranging from 5 min to 1 week. Strong explanatory power is discovered for all sampling frequencies. We also uncover cross-market order flow effects, e.g. GBP exchange rates are very strongly influenced by EUR/USD order flow. We proceed to investigate the predictive power of order flow for exchange rate changes, and it is shown that the order flow specifications reduce RMSEs relative to a random walk for all exchange rates at high-frequencies and for EUR/USD and USD/JPY at lower sampling frequencies.     

Robust estimation of intraweek periodicity in volatility and jump detection

Opening, lunch and closing of financial markets induce a periodic component in the volatility of high-frequency returns. We show that price jumps cause a large bias in the classical periodicity estimators and propose robust alternatives. We find that accounting for periodicity greatly improves the accuracy of intraday jump detection methods. It increases the power to detect the relatively small jumps occurring at times for which volatility is periodically low and reduces the number of spurious jump detections at times of periodically high volatility. We use the series of detected jumps to estimate robustly the long memory parameter of the squared EUR/USD, GBP/USD and YEN/USD returns.

Jump risk,stock returns,and slope of implied volatility smile

In the presence of jump risk, expected stock return is a function of the average jump size, which can be proxied by the slope of option implied volatility smile. This implies a negative predictive relation between the slope of implied volatility smile and stock return. For more than four thousand stocks ranked by slope during 1996–2005, the difference between the risk-adjusted average returns of the lowest and highest quintile portfolios is 1.9% per month. Although both the systematic and idiosyncratic components of slope are priced, the idiosyncratic component dominates the systematic component in explaining the return predictability of slope. The findings are robust after controlling for stock characteristics such as size, book-to-market, leverage, volatility, skewness, and volume. Furthermore, the results cannot be explained by alternative measures of steepness of implied volatility smile in previous studies.
