The impact of the introduction of the Euro on foreign exchange rate risk exposures

This paper tests whether significant changes in stock return volatility, market risk, and foreign exchange rate risk exposures took place around the launch of the Euro in 1999. The experiment analyzes weekly returns for 3220 nonfinancial firms from 18 European countries, the United States, and Japan. We find that though the Euro's launch was associated with an increase in total stock return volatility, significant reductions in market risk exposures arose for nonfinancial firms both in and outside of Europe. We show that the reductions in market risk were concentrated in firms domiciled in the Euro area and in non-Euro firms with a high fraction of foreign sales or assets in Europe. The Euro's introduction led to a net absolute decrease in the foreign exchange rate exposure of nonfinancial firms, but these changes are statistically and economically small. We interpret our findings in the context of existing theories of exchange rate risk management.     

Crossing the lines: The conditional relation between exchange rate exposure and stock returns in emerging and developed markets

This paper examines the importance of exchange rate exposure in the return generating process for a large sample of non-financial firms from 37 countries. We argue that the effect of exchange rate exposure on stock returns is conditional and show evidence of a significant return impact to firm-level currency exposures when conditioning on the exchange rate change. We further show that the realized return to exposure is directly related to the size and sign of the exchange rate change, suggesting fluctuations in exchange rates as a source of time-variation in currency return premia. For the entire sample the return impact ranges from 1.2 to 3.3% per unit of currency exposure, and it is larger for firms in emerging markets compared to developed markets. Overall, the results indicate that foreign exchange rate exposure estimates are economically meaningful, despite the fact that individual time-series results are noisy and many exposures are not statistically significant, and that exchange rate exposure plays an important role in generating cross-sectional return variation. Moreover, we show that the relation between exchange rate exposure and stock returns is more consistent with a cash flow effect than a discount rate effect.     

The effect of exchange rate variability on US shareholder wealth

We examine the relationship between financial crisis exchange rate variability and equity return volatility for US multinationals. Empirical analysis of the major financial crises of the last decades reveals that stock return variability increases significantly in the aftermath of a crisis, even relative to the increase in stock return volatility for other firms belonging to the same industry and market capitalization class. In conjunction with this increase in total volatility, there is also an increase in stock market risk (β) for multinational firms. Moreover, trade and service oriented industries appear to be particularly sensitive to these changing exchange rate conditions.     

Does institutional ownership increase stock return volatility? Evidence from Vietnam

The literature on institutional ownership and stock return volatility often ignores small emerging countries. However, this issue is more profound, due to the large size of institutional investors and small stock market size, in emerging equity markets. This paper examines the effects of the institutional ownership on the firm-level volatility of stock returns in Vietnam. Our data cover most of non-financial firms listed on the Ho Chi Minh City stock exchange for the period 2006–2012. Employing different analysis techniques for panel data and controlling for possible endogeneity problems, our empirical results suggest that institutional investors stabilize the stock return volatility. Moreover, we document that: i) the stabilizing effect of institutional investor ownership is higher in dividend paying firms, and ii) if firms are paying out more dividends, this stabilizing effect is greater. Our results outline the important role of institutional investors in maintaining the stability in emerging stock markets.     

Asset pricing and foreign exchange risk

According to the International Capital Asset Pricing Model (ICAPM), the covariance of assets with foreign exchange currency returns should be a risk factor that must be priced when the purchasing power parity is violated. The goal of this study is to re-examine the relationship between stock returns and foreign exchange risk. The novelties of this work are: (a) a data set that makes use of daily observations for the measurement of the foreign exchange exposure and volatility of the sample firms and (b) data from a Eurozone country.The methodology we make use in reference to the estimation of the sensitivity of each stock to exchange rate movements is that it allows regressing stock returns against factors controlling for market risk, size, value, momentum, foreign exchange exposure and foreign exchange volatility. Stocks are then classified according to their foreign exchange sensitivity portfolios and the return of a hedge (zero-investment) portfolio is calculated. Next, the abnormal returns of the hedge portfolio are regressed against the return of the factors. Finally, we construct a foreign exchange risk factor in such manner as to obtain a monotonic relation between foreign exchange risk and expected returns.The empirical findings show that the foreign exchange risk is priced in the cross section of the German stock returns over the period 2000-2008. Furthermore, they show that the relationship between returns and foreign exchange sensitivity is nonlinear, but it takes an inverse U-shape and that foreign exchange sensitivity is larger for small size firms and value stocks.     

Exchange rate variability and the riskiness of US multinational firms: evidence from the Asian financial turmoil

This paper studies the relationship between exchange rate variability and the volatility of the returns of US multinationals. Based on a sample of US multinationals with sales in the Asia-Pacific region, we examine how exchange rate fluctuations around the 1997 Asian financial crisis affected the sensitivity of those firms to stock market risk. The empirical evidence shows that increases in exchange rate variability during the crisis were associated with statistically significant increases in stock return volatility for the multinationals. Some of the increases in volatility were systematic in nature, because the beta coefficients of the firms rose during the period of increased exchange rate variability.     

Exchange Rate Exposure at the Firm and Industry Level

Previous work on the exposure of firms to exchange rate risk has primarily focused on U.S. firms and, surprisingly, found stock returns were not significantly affected by exchange‐rate fluctuations. The equity market premium for exposure to currency risk was also found to be insignificant. In this paper we examine the relation between Japanese stock returns and unanticipated exchange‐rate changes for 1,079 firms traded on the Tokyo stock exchange over the 1975–1995 period. Second, we investigate whether exchange‐rate risk is priced in the Japanese equity market using both unconditional and conditional multifactor asset pricing testing procedures. We find a significant relation between contemporaneous stock returns and unanticipated yen fluctuations. The exposure effect on multinationals and high‐exporting firms, however, is found to be greater in comparison to low‐exporting and domestic firms. Lagged‐exchange rate changes on firm value are found to be statistically insignificant implying that investors are able to assess the impact of exchange‐rate changes on firm value with no significant delay. The industry level analysis corroborates the cross‐sectional findings for Japanese firms in that they are sensitive to contemporaneous unexpected exchange‐rate fluctuations. The co‐movement between stock returns and changes in the foreign value of the yen is found to be positively associated with the degree of the firm's foreign economic involvement and inversely related to its size and debt to asset ratio. Asset pricing tests show that currency risk is priced. We find corroborating evidence in support of the view that currency exposure is time varying. Our results indicate that the foreign exchange‐rate risk premium is a significant component of Japanese stock returns. The combined evidence from the currency exposure and asset pricing analyses, suggests that currency risk is priced and, therefoe, has implications for corporate and portfolio managers.     

Exchange rate exposure and the use of foreign currency derivatives in the Australian resources sector

In this paper, we provide a re-examination of the exchange rate exposure and foreign currency derivative use by Australian resources firms in the 2006–2009 period which is characterized by increased volatility caused by the global financial crisis. In particular, we consider the interaction of a resources firm's exchange rate risk exposures, foreign currency derivative use and the global financial crisis simultaneously. Conforming to expectations, our results indicate that more companies are significantly exposed to exchange rate risk since the onset of the financial crisis. However, there is a lack of evidence that the use of foreign currency derivative is more effective in alleviating exchange rate exposures during the crisis as opposed to the pre-crisis period.

Does foreign institutional ownership increase return volatility? Evidence from China

This paper investigates the impact of foreign institutional ownership on firm-level stock return volatility in China, based on our study of a sample of 1458 firms between 1998 and 2008. The empirical results show that share ownership by foreign institutions (both financial and non-financial) increases firm-level stock return volatility, even after controlling for a complete ownership structure, firm size, turnover, and leverage, and correcting for potential endogeneity problems. However, the results also show that foreign individual shareholdings reduce volatility. Furthermore, we document a positive relationship between domestic shareholdings (individual, institutional, and governmental) and firm-level stock return volatility. Empirical results with interaction terms show that foreign institutional ownership increases firm-level return volatility by strengthening the positive impact of liquidity on volatility. The volatility reduction effect of foreign individual ownership is attenuated by government ownership suggests a poor governance environment as a result of the involvement of the Chinese government.     

How does news sentiment affect the states of Japanese stock return volatility?

This paper examines the impact of public news sentiment on the volatility states of firm-level returns on the Japanese Stock market. We firstly adopt a novel Markov Regime Switching Long Memory GARCH (MRS-LMGARCH), which is employed to estimate the latent volatility states of intraday stock return. By using the RavenPack Dow Jones News Analytics database, we fit discrete choice models to investigate the impact of news sentiment on changes of volatility states of the constituent stocks in the TOPIX Core 30 Index. Our findings suggest that news occurrence and sentiment, especially those of macro-economic news, are a key factor that significantly drives the volatility state of Japanese stock returns. This provides essential information for traders of the Japanese stock market to optimize their trading strategies and risk management plans to combat volatility.     

Impact of exchange rate movements on exports: An analysis of Indian non-financial sector firms

We explore the real effective exchange rate (REER) effects on the share of exports of Indian non-financial sector firms for the period 2000–2010. Our empirical analysis reveals that, on average, there has been a strong and significant negative impact from currency appreciation and currency volatility on Indian firms' export shares. Labor costs are found to intensify the exchange rate effects on trade. Further, there is evidence that the Indian firms considered here respond asymmetrically to exchange rates. For instance, the REER change effect is more likely to be driven by a negative appreciation effect than a depreciation effect. Also, Indian firms that have smaller export shares tend to have a stronger response to both REER change and volatility. Compared with those exporting goods, firms that export services are more affected by exchange rate fluctuations. The findings, especially those on asymmetric responses, have important policy implications.     

The time-varying diversifiability of corporate foreign exchange exposure

Estimating comovement measures for a large set of bilateral foreign exchange (FX) rates, I explore the relation between firm-level FX exposure and its time-varying diversifiability. For a sample of U.S. firms, the magnitude of FX exposure appears to increase during periods of low currency risk diversifiability. Additional results suggest that the introduction of the euro exacerbated the effect of diversifiability on developed market currency exposure. Moreover, the low diversifiability of emerging market currencies seems to have a stronger effect on FX exposure than the low diversifiability of developed market currencies.     

Dynamic spillovers between commodity and currency markets

In this study, we examine the dynamic link between returns and volatility of commodities and currency markets. Based on weekly data over the period from January 6, 1987 to July 22, 2014, we find the following empirical regularities. First, our results suggest that the information contents of gold, silver, platinum, and the CHF/USD and GBP/USD exchange rates can help improve forecast accuracy of returns and volatilities of palladium, crude oil and the EUR/CHF and GBP/USD exchange rates. Second, gold (CHF/USD) is the dominant commodity (currency) transmitter of return and volatility spillovers to the remaining assets in our model. Third, the analysis of dynamic spillovers shows time- and event-specific patterns. For instance, the dynamic spillover effects originating in gold and silver (platinum) returns and volatility intensified (degraded) in the period marked by the global financial crisis. After the global financial crisis, the net transmitting role of gold and silver (platinum) returns shocks weakened (strengthened), while the net transmitting role of gold, silver and platinum volatility shocks remained relatively high. Overall, our findings reveal that, while the static analysis clearly classifies the aforementioned variables into net transmitters and net receivers, the dynamic analysis denotes episodes wherein the role of transmitters and receivers of return (volatility) spillovers can be interrupted or even reversed. Hence, even if certain commonalities prevail in each identified category of commodities, such commonalities are time- and event-dependent.

Does Risk Management Add Value? A Survey of the Evidence

The fact that 92% of the world's 500 largest companies recently reported using derivatives suggests that corporate managers believe financial risk management can increase shareholder value. Surveys of finance academics indicate that they too believe that corporate risk management is, on the whole, a valueadding activity. This article provides an overview of almost 30 years of broadbased, stock‐market‐oriented academic studies that address one or more of the following questions:

• ? Are interest rate, exchange rate, and commodity price risks reflected in stock price movements?
• ? Is volatility in corporate earnings and cash flows related in a systematic way to corporate market values?
• ? Is the corporate use of derivatives associated with reduced risk and higher market values?

The answer to the first question, at least in the case of financial institutions and interest rate risk, is a definite yes; all studies with this focus find that the stock returns of financial firms are clearly sensitive to interest rate changes. The stock returns of industrial companies exhibit no pronounced interest rate exposure (at least as a group), but industrial firms with significant cross‐border revenues and costs show considerable sensitivity to exchange rates (although such sensitivity actually appears to be reduced by the size and geographical diversity of the largest multinationals). What's more, the corporate use of derivatives to hedge interest rate and currency exposures appears to be associated with lower sensitivity of stock returns to interest rate and FX changes. But does the resulting reduction in price sensitivity affect value—and, if so, how? Consistent with a widely cited theory that risk management increases value by limiting the corporate “underinvestment problem,” a number of studies show a correlation between lower cash flow volatility and higher corporate investment and market values. The article also cites a small but growing group of studies that show a strong positive association between derivatives use and stock price performance (typically measured using price‐to‐book ratios). But perhaps the nearest the research comes to establishing causality are two studies—one of companies that hedge FX exposures and another of airlines' hedging of fuel costs—that show that, in industries where hedging with derivatives is common, companies that hedge outperform companies that don't.     

Firm size and volatility analysis in the Spanish stock market

Using Spanish stock market data, this paper examines volatility spillovers between large and small firms and their impact on expected returns. By using a conditional capital asset pricing model (CAPM) with an asymmetric multivariate GARCH-M covariance structure, it is shown that there exist bidirectional volatility spillovers between both types of companies, especially after bad news. After estimating the model, a positive and significant price of risk is obtained. This result is consistent with the volatility feedback effect, one of the most popular explanations of the asymmetric volatility phenomenon, and explains why risk premiums are much more sensitive to negative return shocks coming from the whole market or other related markets.     

On the Credibility of the Euro/Swiss Franc Floor: A Financial Market Perspective

We estimate the risk‐neutral break probabilities of a realignment of the EUR/CHF 1.20 floor, maintained by the SNB from September 6, 2011, to January 15, 2015, using put options and an option pricing model, which assumes a lower barrier for the exchange rate. We estimate probabilities considerably different from zero, even when the exchange rate traded far above the floor. We observe a drastic increase in the break probabilities up to approximately 50% shortly before the floor was abandoned. From an option market perspective, the credibility of the SNB in maintaining the floor was, thus, substantially lower than publicly claimed.     

The pricing of foreign exchange risk around the Asian financial crisis: evidence from Taiwan's stock market

The volatile exchange rate movement during the Asian financial crisis has led global investors to re-evaluate the importance of currency exposures in Asian stock markets. In this paper, we examine industry-level currency risk of Taiwan's stock market around the Asian financial crisis. The results show that most export-oriented industries, except for the electronics industry, are positively affected by the depreciation of the New Taiwan Dollars (NTD) against the US Dollars (USD). We also find that the magnitude of currency risk is less for banking and electronics industries in the Taiwan Stock Exchange (TSE) than for those in the over-the-counter (OTC) security exchange. Our results are consistent with the findings of Chow et al. (J. Financial Res. 2 (1997b) 191) and have important implications for international investors with exposures in Taiwan's stock market.     

Exchange rate exposure in the Asian emerging markets

This paper investigates the impact of foreign exchange rate change on stock returns in the Asian emerging markets. The asymmetric exchange exposure framework and real exchange rates are used in this paper to capture the different exposures between currency appreciation and depreciation and the high inflation effect in the emerging markets. My empirical results show that there did exist extensive exchange rate exposure in the Asian emerging markets from 1997 to 2010. Moreover, foreign exchange exposure became more significant or greater during the 1997 Asian crisis and the 2008 global crisis periods, despite the frequent central banks’ interventions during these periods. The greater exchange exposure during the crisis periods can be attributable to net exporters or firms with dollar assets, implying that firms can reduce exchange exposures by decreasing their export ratio or dollar assets holding during times of crisis.
