The pricing of currency risk in Japan

Previous work on the pricing of exchange-rate risk has primarily focused on US firms and, surprisingly, found stock returns were not significantly affected by exchange-rate fluctuations. In this paper we conduct an in-depth investigation that examines whether exchange-rate risk is priced in the equity market of Japan using an intertemporal asset pricing testing procedure that allows risk premia to change through time in response to changes in macroeconomic conditions. Our multiperiod asset pricing tests show that the foreign exchange-rate risk premium is a significant component of Japanese stock returns. Specifically, the results suggest that currency-risk exposure commands a significant risk premium for multinationals and high-exporting Japanese firms. The currency-risk factor is found to be less influential in explaining the behavior of average returns for low-exporting and domestic firms. However, it is shown to exhibit large return volatility that is likely to be perceived by investors, who wish to control portfolio risk, as an important underlying source of risk. Furthermore, Japanese stock returns are found to be related to the relative distress and size factors above and beyond the covariation explained by the currency-risk factor.     

Local risk factors in emerging markets: Are they separately priced?

We provide new evidence on the pricing of local risk factors in emerging stock markets. We investigate whether there is a significant local currency premium together with a domestic market risk premium in equity returns within a partial integration asset pricing model. Given previous evidence on currency risk, we conduct empirical tests in a conditional setting with time-varying prices of risk. Our main results support the hypothesis of a significant exchange risk premium related to the local currency risk. Exchange rate and domestic market risks are priced separately for our sample of seven emerging markets. The empirical evidence also suggests that although statistically significant, local currency risk is on average smaller than domestic market risk but it increases substantially during crises periods, when it can be almost as large as market risk. Disentangling these two factors is thus important in tests of international asset pricing for emerging markets.     

Exchange rate and inflation risk premia in the EMU

This paper tests the effects of exchange rate and inflation risk factors on asset pricing in the European Union (EU) stock markets. This investigation was motivated by the results of Vassalou [J. Int. Money Finance, 2000, 19, 433–470] showing that both exchange rate and foreign inflation are generally priced in equity returns, and it studies the opportunity of evaluating the causality between these sources of risk after the elimination of the EU currency risks because of the adoption of the single currency. Our results show that both exchange rate and inflation risks are significantly priced in the pre- and post-euro periods. Moreover, the sizes of exchange rate and inflation risk premiums are economically significant in the pre- and post-euro periods. Futhermore, the UK and excluding-UK inflation risk premiums explain, in part, our evidence concerning a large EUR/GBP exchange rate risk premium and the existence of an economically significant domestic non-diversifiable risk after euro adoption. Hence overlooking inflation risk factors can produce an under/overestimation of the currency premiums and a miscalculation of the degree of integration of stock markets.     

Foreign exchange risk pricing and equity market segmentation in Africa

This work is the first to investigate simultaneously the occurrence of unconditional currency risk pricing and equity market segmentation in Africa’s major stock markets. The multi-factor asset pricing theory provides the theoretical framework for our model. We find strong evidence suggesting that Africa’s equity markets are partially segmented. However, we find insufficient evidence to reject the hypothesis that foreign exchange risk is not unconditionally priced in Africa’s stock markets. This result is robust to alternative foreign exchange rate-adjusted return measures. These findings suggest that international investors can diversify into Africa’s equity markets without worrying about unconditional risks associated with foreign exchange rate fluctuations.     

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.     

Pricing currency risk in the stock market: Evidence from Finland and Sweden 1970-2009

We investigate the role of currency risk on stock markets in two interlinked Nordic countries exhibiting a gradual move from fixed to floating exchange rates. We apply the Ding and Engle (2001) covariance stationary specification in a multivariate GARCH-M setup to test a conditional international asset pricing model. Using a sample period from 1970 to 2009, we find that the currency risk is priced in both stock markets, and that the price and the risk premium are lower after the floatation of the currencies, especially for Finland. We also find the cross-country exchange rate shock from Finland to affect the price of currency risk in Sweden, but not vice versa. Finally, we discuss some of the potential issues in applying multivariate GARCH-M specifications in tests of asset pricing models.     

Foreign Exchange Volatility Is Priced in Equities

This paper finds that standard asset pricing models fail to explain the significantly negative delta hedging errors that occur as a result of the purchase of options on foreign exchange futures. Foreign exchange volatility does influence stock returns, however. The volatility of the JPY/USD exchange rate predicts the time series of stock returns and is priced in the cross‐section of stock returns.     

Exchange Rates and the Conversion of Currency‐Specific Risk Premia

How do the risk factors that drive asset prices influence exchange rates? Are the parameters of asset price processes relevant for specifying exchange rate processes? Most international asset pricing models focus on the analysis of asset returns given exchange rate processes. Little work has been done on the analysis of exchange rates dependent on asset returns. This paper uses an international stochastic discount factor (SDF) framework to analyse the interplay between asset prices and exchange rates. So far, this approach has only been implemented in international term structure models. We find that exchange rates serve to convert currency‐specific discount factors and currency‐specific prices of risk – a result linked to the international arbitrage pricing theory (IAPT). Our empirical investigation of exchange rates and stock markets of four countries presents evidence for the conversion of currency‐specific risk premia by exchange rates.     

Industry‐Specific Human Capital,Idiosyncratic Risk,and the Cross‐Section of Expected Stock Returns

Human capital is one of the largest assets in the economy and in theory may play an important role for asset pricing. Human capital is heterogeneous across investors. One source of heterogeneity is industry affiliation. I show that the cross‐section of expected stock returns is primarily affected by industry‐level rather than aggregate labor income risk. Furthermore, when human capital is excluded from the asset pricing model, the resulting idiosyncratic risk may appear to be priced. I find that the premium for idiosyncratic risk documented by several empirical studies depends on the covariance between stock and human capital returns.     

Stock return exposure to exchange rate risk: A perspective from delayed reactions and hedging effects

This paper investigates the absence of prevailing evidence on the significant exposure of US stocks to exchange rate risk by considering a firm's pre-hedging currency exposure, its expected hedging activity and the delayed reaction of its stocks to currency movements. Although we demonstrate the importance of lagged exposure relative to contemporaneous exposure, the inclusion of the lagged effect in the exposure measurement still fails to raise the significance of the exchange rate risk with regard to the pricing for the overall sample of stocks. We further demonstrate that the weak evidence on priced currency risk is at least partly attributable to hedging activity, particularly for large firms. Finally, our results provide partial support for the asymmetric hedging hypothesis, in that asymmetric hedging is found to be responsible for reshaping the relationship between a firm's characteristics and its currency exposure.     

Firm-level effects of asymmetric intervention in foreign exchange markets: Evidence from the Swiss currency floor

In January 2015, the Swiss National Bank (SNB) abandoned the Swiss franc's exchange rate floor against the Euro. This paper is the first to study the firm-level effects of this asymmetric type of central bank intervention in foreign exchange markets. Using weekly stock returns for a sample of Swiss non-financial firms, I find significant reductions in total stock return volatility as well as market risk following the introduction of the currency floor. Accounting for the asymmetric nature of the intervention, I show that the enforcement of this policy solely manifests in a significant reduction of incremental EUR/CHF exchange rate risk exposures of exporting firms, while importing firms experience reductions in proportion to the market portfolio only. Thus, the asymmetric policy design is reflected in asymmetric responses of firm-level currency exposures. All effects, however, do not depend on the extent of business activity in the Eurozone. The overall results suggest that the currency floor was successful in supporting the performance of the Swiss economy by effectively reducing stock return sensitivities to market fluctuations and EUR/CHF exchange rate volatility.     

The exchange rate exposure of U.S. and Japanese banking institutions

In this paper, we examine the foreign exchange exposure of a sample of U.S. and Japanese banking firms. Using daily data, we construct estimates of the exchange rate sensitivity of the equity returns of the U.S. bank holding companies and compare them to those of the Japanese banks. We find that the stock returns of a significant fraction of the U.S. companies move with the exchange rate, while few of the Japanese returns that we observe do so. We next examine more closely the sensitivity of the U.S. firms by linking the U.S. estimates cross-sectionally to accounting-based measures of currency risk. We suggest that the sensitivity estimates can provide a benchmark for assessing the adequacy of existing accounting measures of currency risk. Benchmarked in this way, the reported measures that we examine appear to provide a significant, though only partial, picture of the exchange rate exposure of U.S. banking institutions. The cross-sectional evidence is also consistent with the use of foreign exchange contracts for the purpose of hedging.     

Firm characteristics and the impact of emerging market liberalizations

We provide a firm level analysis of the impact of capital market liberalization in 18 emerging markets. Consistent with models of international asset pricing, we find that firms’ stock returns increase during liberalization and that a majority of firms have lower mean returns and lower dividend yields after liberalization. We also find that emerging market firms have increased exposure to the world market and decreased exposure to the home market following liberalization. These changes in returns and exposures support the predictions of theoretical international asset pricing models. We also test and find support for the importance of size, local risk, foreign exchange risk, and cross-listing status in explaining the cross-section of changes in returns.     

Asymmetric foreign exchange risk exposure: Evidence from U.S. multinational firms

This paper examines how U.S. multinational firms are affected by foreign currency movements. In light of detailed exchange rate data, we find that 29% of our sample of 935 U.S. firms with real operations in foreign countries is significantly affected by currency movements between 1990 and 2001. Results show moreover that U.S. stock returns react asymmetrically to currency movements. By introducing nonlinearity in foreign currency risk exposure, we noticeably increase the precision and the significance of exposure estimates. We demonstrate moreover that asymmetries are more pronounced towards large versus small currency fluctuations than over depreciation and appreciation cycles.     

Corporate social responsibility as a common risk factor

This article challenges factor models widely used to explain stock returns. For European firms involved in corporate social responsibility (CSR) actions, we find a risk premium associated with extra-financial ratings priced by the market (that is, environmental, social, and governance [ESG] ratings). This premium is calculated as the excess return of low-rated firms compared to high-rated firms. To describe rated firms' returns, we propose a parsimonious two-factor model that includes both the market factor and this premium. Unlike the CAPM, three-, or five-factor models, our model is validated by the Gibbons, Ross and Shanken (1989) test. Our results lead to many managerial implications related to portfolio management, asset pricing, and corporate financial and investing decisions.     

Pass-through and Exposure

Firms differ in the extent to which they "pass through" changes in exchange rates into foreign currency prices and in their "exposure" to exchange rates—the responsiveness of their profits to changes in exchange rates. Because pricing affects profitability, a firm's pass-through and exposure should be related. This paper develops models of exporting firms under imperfect competition to study these related phenomena. From these models we derive the optimal pass-through decisions and the resulting exchange rate exposure. The models are estimated on eight Japanese export industries using both the price data pass-through and financial data for exposure.     

The valuation-relevance of the foreign translation adjustment: The effect of barriers to entry

We examine the economic effects of barriers to entry on the association between foreign currency translation adjustments and the stock returns of multinational firms operating in the manufacturing and service industries. Firms that are innovation leaders, that is, firms that are research and development (R&D) intensive and firms with high foreign asset intensity (i.e., asset-intensive firms), are our proxies for firms operating in environments with barriers to entry (i.e., environments in which competition is less intense). We hypothesize and find that foreign currency translation adjustments are positively associated with abnormal stock returns for firms operating in environments with barriers to entry in both manufacturing and service industries. This finding highlights the importance of assessing the valuation-relevance of foreign currency translation adjustments by considering the economic contexts of foreign currency movements. Overall, the evidence shows that the accounting rules governing foreign currency translations generally produce results consistent with the economic effects of foreign exchange rate changes.     

DO FOREIGN INVESTORS PRICE FOREIGN EXCHANGE RISK DIFFERENTLY?

We test whether foreign investors price foreign exchange risk differently from local investors. Drawing from the closed‐end country fund literature, we argue that both differential access to information by foreign versus local investors and different sources of exchange risk that investors face (economic or translation exposure) will lead to different pricing of the exchange risk associated with American Depositary Receipt (ADR) investments. We apply a two‐step method to country portfolios of ADRs of Australia, France, Japan, and the United Kingdom traded on the New York Stock Exchange. Our results show that foreign investors generally price exchange risk differently from local investors, and that the source and magnitude of differences in exchange risk pricing vary significantly across countries. Although significant differences in pricing exchange risk between foreign and local investors are observed for Australia, France, and Japan, no such pricing difference is noticed for the United Kingdom. Furthermore, the pricing differences observed for Australian and French ADRs are mainly attributed to the exchange risk of underlying share returns (economic exposure), whereas the pricing differences for Japanese ADRs are mainly attributed to the exchange risk associated with currency translation (translation exposure). We offer some explanations for our findings.     

Exchange risk and universal returns: A test of international arbitrage pricing theory

According to the international arbitrage pricing theory (IAPT) posited by Solnik (1983), currency movements affect assets' factor loadings and associated risk premiums. Based on a novel universal return decomposition, we propose an empirical model to test this proposition and perform tests using U.S. stock returns in the period 1975–2008. Our results confirm that currency movements significantly affect the market betas of a large proportion of stocks. Further cross-sectional tests indicate that currency movements affecting the market factor are significantly priced in stock returns. Based on these and other findings, we conclude that Solnik's IAPT is supported. An important implication of our findings is that exchange rate risk can broadly affect stock returns through both factor loading and residual factor channels.     

Can hedging tell the full story? Reconciling differences in United States aggregate- and industry-level exchange rate risk premium

While the importance of currency movements to industry competitiveness is theoretically well established, there is little evidence that currency risk impacts US industries. Applying a conditional asset pricing model to 36 US industries, we find that all industries have a significant currency premium that adds about 2.47 percentage points to the cost of equity and accounts for approximately 11.7% of total risk premium in absolute value. Cross-industry variation in the currency premium is explained by foreign income, industry competitiveness, leverage, liquidity, and other industry characteristics, while its time variation is explained by US aggregate foreign trade, monetary policy, growth opportunities, and other macro variables. The results indicate that methodological weakness, not hedging, explains the insignificant industry currency risk premium found in previous work, thus resolving the puzzle that currency risk premium is important at the aggregate stock market level, but not at the industry level.
