Monetary control with an exchange rate objective: The bank of Japan, 1973–86

This paper analyzes the switch in monetary control procedures by the Bank of Japan toward a so-called ‘money-focused’ monetary policy in the mid-1970s. The extent to which monetary control under the new regime has been limited by an exchange rate objective is examined. Through estimation of an explicit Bank of Japan (BoJ) reaction function, we find evidence that the BoJ operating instrument has been systematically manipulated with a view to maintain short-term money control but that this objective has often been dominated by an attempt to moderate yen– dollar exchange rate fluctuations.     

The accuracy of reports of foreign exchange intervention by the Bank of Japan: Does Tokyo know more?

This paper examines the accuracy of press reports of foreign exchange intervention by the Bank of Japan. We investigate whether the local news wire (JiJi News) reacted differently from the foreign press (Wall Street Journal) between January 2000 and December 2003. Our results show that the likelihood of intervention being reported given that it actually occurred is higher for the JiJi News than for the Wall Street Journal, but the JiJi News has many more instances of false speculative intervention reports. As such, the underreporting by the Wall Street Journal mitigates its overall errors as compared to the JiJi News. We find that the change of Japan's intervention strategy from the beginning of 2003 has a major impact on the accuracy of press reports. Logit analysis also demonstrates that the likelihood of intervention being firmly reported increased with the size of the intervention and the magnitude of appreciation of the Japanese yen.     

The Rise and Fall of Foreign Exchange Market Intervention as a Policy Tool

The premise of the paper is that the fervor for foreign exchange market intervention by U.S, and European monetary authorities has ebbed in recent years. A pattern of initial belief in the effectiveness of foreign exchange market intervention has recently been eroded, as is revealed by the absence of intervention in circumstances that in earlier times would have invoked it. Only the Bank of Japan among central banks of the developed world has not thusfar abandoned its faith that intervention can change the relative value of the yen as determined by market forces to conform with its notion of what that value should be. To explain why U.S. and European monetary authorities no longer believe that intervention is a tool that works, I review the equivocal record of past episodes, the inconclusive results of empirical research, and the problems of implementation that intervention advocates ignore.     

Portfolio capital flows and the US dollar exchange rate: Viewed from the lens of time and frequency dynamics of connectedness

This study uses proprietary data on daily net non-resident portfolio flows to emerging markets to analyse the interconnectedness of non-resident debt and equity portfolio flows under different market conditions. We find that there is less interconnectedness during normal times but increased interconnectedness during periods of uncertainty and stress, suggesting an asymmetry in the spillovers of these portfolio flows. Importantly, we find that shocks in the broad EM US dollar exchange rate are a net transmitter of shocks to debt and equity portfolio flows of EM economies. Our analysis, based on the net directional spillover index, shows that this effect is most pronounced during the COVID-19 pandemic. Furthermore, using a frequency domain approach to connectedness, we find that the broad EM US dollar exchange rate is a net transmitter of shocks to the EM economies’ debt and equity flows, with the impact hitting portfolio capital flows within at least a week to 100 days. Our results suggest that pre-emptive macroprudential policy measures and better risk monitoring can improve the resilience of borrowers and investors in EM economies during times of global shocks, particularly during US dollar appreciations when portfolio flows tend to reverse.     

A New Method for Identifying the Effects of Foreign Exchange Interventions

Central banks react even to intraday changes in the exchange rate; however, in most cases, intervention data are available only at a daily frequency. This temporal aggregation makes it difficult to identify the effects of interventions on the exchange rate. We apply the Bayesian Markov‐chain Monte Carlo (MCMC) approach to this endogeneity problem. We use “data augmentation” to obtain intraday intervention amounts and estimate the efficacy of interventions using the augmented data. Applying this new method to Japanese data, we find that an intervention of 1 trillion yen moves the yen/dollar rate by 1.8%, which is more than twice as much as the magnitude reported in previous studies applying ordinary least squares to daily observations. This shows the quantitative importance of the endogeneity problem due to temporal aggregation.     

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.     

Central bank interventions and implied exchange rate correlations

This paper examines the effects of the foreign exchange market interventions by the Bank of Japan on the ex ante correlations between the JPY/USD, EUR/USD, and GBP/USD exchange rates. The correlation estimates used in the analysis are derived from the market prices of OTC currency options. The results show that central bank interventions significantly affect the market expectations about future exchange rate co-movements. In particular, we find that interventions tend to temporarily increase the ex ante correlations among the major exchange rates. However, our results also suggest that intervention episodes are associated with lower-than-average levels of exchange rate correlations.     

Central bank intervention and the volatility of foreign exchange rates: evidence from the options market

This paper tests the effects of central bank intervention on the ex ante volatility of $/DM and $/yen exchange rates between 1985 and 1991. In contrast to previous research which employed GARCH estimates of conditional volatility, we estimate ex ante volatility using the implied volatilities of currency option prices. We also control for the effects of other macroeconomic announcements. We find little support for the hypothesis that central bank intervention decreases expected exchange rate volatility. Instead, central bank intervention is generally associated with a positive change in ex ante exchange rate volatility, or with no change.

On the determinants of “small” and “large” foreign exchange market interventions: The case of the Japanese interventions in the 1990s

During the past 30 years, central banks have often intervened in foreign exchange markets, and the magnitude of their foreign exchange market interventions has varied widely. We develop a quantitative reaction function model that renders it possible to examine the determinants of “small” and “large” interventions. We apply the model to analyzing the intervention policy of the Japanese monetary authorities (JMA) in the yen/U.S. dollar market during the period from 1991 through 2001. To this end, we use recently released official data on the foreign exchange market interventions of the JMA. We find that the JMA tended to conduct large interventions when the yen/U.S. dollar exchange rate drifted away from an “implicit target exchange rate.”     

What Drives ETF Flows?

The value of exchange traded fund (ETF) assets has increased from $66 billion in 2000 to almost a trillion dollars in 2010. We use this massive expansion in ETF assets to study what drives ETF flows. Using a data set of over 500 ETFs from 2001 to 2010, we show that ETF investors chase returns in the same way as mutual fund investors. While there is an active debate about whether return chasing by mutual fund investors represents the pursuit of superior talent, the existence of return chasing in this passively managed environment should not represent a search for skilled managers. We also show that ETF flows increase following high volume, small spreads, and high price/net asset value ratios. Finally, we find little evidence of superior market timing in ETF flows. Our results suggest that return chasing in both mutual funds and ETFs is more likely the result of naïve extrapolation bias on the part of investors that has contributed to the growth of the ETF industry.     

Central Bank Intervention in USD/INR Market: Estimating Its Reaction Function and Impact on Volatility

Econometric evidence on why central banks intervene in the foreign exchange market and the impact of such intervention has remained inconclusive. We contribute to the literature with evidence from India, a managed float regime that sees consistent monitoring and intervention by Reserve Bank of India, India’s central bank. Estimation of the central bank reaction function shows that increased volatility in the foreign exchange market and misalignment from targeted rates are important objectives behind intervention. The paper further uses the GARCH framework to study how intervention influences exchange rate volatility. We find that intervention in the spot market increases volatility while that in the forward market reduces volatility.     

Intervention policy of the BoJ: A unified approach

Intervening in the FX market implies a complex decision process for central banks. Monetary authorities have to decide whether to intervene or not, and if so, when and how. Since the successive steps of this procedure are likely to be highly interdependent, we adopt a nested logit approach to capture their relationships and to characterize the prominent features of the various steps of the intervention decision process. Our estimations based on Japanese data from 1991 to 2004 indicate that the Bank of Japan: (i) mainly reacted to deviations of the exchange rate with respect to fundamentals and (ii) tended to favour secrecy when its credibility was low. We also provide new insights on the so-called secrecy puzzle by modeling explicitly the risk for a secret intervention to be detected. Our results have important implications in terms of exchange rate policy, such as the emergence of a trade-off between intervention size, communication policy and secrecy. Our results tend to provide some explanation for the observed persistence of ineffective intervention policy during some sub-periods.     

US money announcements and covered interest parity: The case of Japan

This paper examines the effects of US money announcements on dollar-and yen-denominated securities in their respective onshore markets. The effects are consdered over several periods corresponding to possible US and Japanese policy regimes. The consistency of the responses is further examined by testing whether the responses of dollar-denominated securities, yen-denominated securities, the spot yen/dollar exchange rate, and the forward yen/dollar exchange rate violate covered interest parity. Given the results of previous studies, the evidence suggests that restrictions on capital mobility in Japan have not allowed complete international integration of Japanese financial markets.     

Distributive inefficiency in horizontal mergers: Evidence from wealth transfers between merging firms and their customers

The ultimate goal of antitrust enforcement is to maximize the surplus consumers enjoy by enhancing production efficiency and eliminating market power. Previous literature focuses on the average net wealth effects on merging firms and their stakeholder firms and reports evidence of efficiency gains while no evidence of market power in horizontal mergers. In this paper, we examine how efficiency gains distribute between the merging firms and their customer firms. We find a significant negative relation between the combined abnormal returns on the merging firms and those on their customer firms, demonstrating a wealth transfer effect. Such a negative relation is more pronounced when market power is likely to be more intensive. On average, the merging firms gain, and their customers do not lose. Our results suggest that market power allows merging firms to withhold merger gains that would have been passed to the downstream under perfect competition and prevents customers from enjoying the whole consumer surplus. Distributive inefficiency exists in horizontal mergers.     

An Empirical Evaluation of the Usefulness of Non-GAAP Accounting Measures in the Real Estate Investment Trust Industry

We conduct three sets of analyses to compare the usefulness of net income, based on generally accepted accounting principals (GAAP), and the industry-advanced funds from operations (FFO) in the context of the real estate investment trust (REIT) industry. In our first set of tests, we find that FFO is more strongly associated with one-year ahead FFO and one-year ahead operating cash flows than is net income. Conversely, we find that net income explains more variation in one-year ahead net income and current stock price than does FFO. Second, in support of the claim that some REITs manipulate FFO, we document that young REITs and REITs that are likely to access capital markets are more likely to manage FFO. Third, we find that, for a sample of firms that disclose current value information, both net income and FFO fail to reflect holding gains or losses on unsold properties in a timely manner. Overall, our analyses suggest that the REIT industry's claim that FFO is more useful than net income is premature because the superiority of one measure over the other is highly contextual.

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.     

Political Stability and the Effectiveness of Currency Based Macro Prudential Measures

The use of multiple currency based macroprudential tools by Reserve Bank of India, India’s central bank, has helped create resilience in the economy, especially during financial turmoil. However, in a democratic set-up like India, the analysis of capital based macroprudential reforms needs to incorporate the political stability, as there is increasing evidence that macroprudential policy effectiveness is closely linked to political conditions. This study incorporates the role of political stability is understanding the effectiveness of currency based macroprudential policies, by using the years of election as a proxy for political uncertainty. I develop an index of capital based macroprudential policies (CMPP) using the notifications on capital flows and risk management guidelines on foreign exchange exposures from Reserve Bank of India. Using a GARCH model, the impact of CMPP on the net capital inflows is analyzed for the period from January, 1997 to March, 2018. I find that while the presence of CMPP leads to a fall in capital flow volatility, such policies in the years of election are ineffective in curbing capital flow volatility. The paper adds to the increasing evidence coming in recent years of the link between political cycles, interest groups and macroprudential policies.

     

An investigation of customer order flow in the foreign exchange market

This paper examines the effect that heterogeneous customer orders flows have on exchange rates by using a new, and the largest, proprietary dataset of weekly net order flow segmented by customer type across nine of the most liquid currency pairs. We make several contributions. Firstly, we investigate the extent to which customer order flow can help to explain exchange rate movements over and above the influence of macro-economic variables. Secondly, we address the issue of whether order flows contain (private) information which explain exchange rates changes. Thirdly, we look at the usefulness of order flow in forecasting exchange rate movements at longer horizons than those generally considered in the micro-structure literature. Finally we address the question of whether the out-of-sample exchange rate forecasts generated by order flows can be employed profitably in the foreign exchange markets.
