Central bank intervention and exchange rate volatility: Evidence from Japan using realized volatility

This paper presents new empirical evidence on the effectiveness of Bank of Japan's foreign exchange interventions on the daily realized volatility of USD/JPY exchange rates using high frequency data. Following Huang and Tauchen (2005) and Barndorff-Nielsen and Shephard, 2004, Barndorff-Nielsen and Shephard, 2006, we use bi-power variation to decompose daily realized volatility into two components: the smooth persistent and the discontinuous jump components. We model exchange rate returns, the different components of realized volatility and the central bank intervention using a system of simultaneous equations. We find strong support that interventions by Bank of Japan had increased both the continuous and the jump components of daily realized volatility. This suggests that the interventions by Bank of Japan had increased market volatility which not only caused short-lived positive jumps, but were also persistent over time. We did not find any evidence that interventions were effective in influencing the exchange rate returns for the entire sample period.     

A reinvestigation of the new RMB exchange rate regime

To examine the new renminbi exchange rate regime rigorously, we employ the STARTZ model to investigate renminbi nominal effective exchange rate behavior from mid-2006 to mid-2008. A managed float with a target central parity and without an explicit band best describes the daily exchange rate movement between renminbi and other currencies. We also find some peculiar attributes of the renminbi nominal effective exchange rate, including small conditional variance and stronger effects from government interventions in foreign exchange markets.     

Effect of exchange rate return on volatility spill-over across trading regions

This paper examines the effect of realized exchange rate returns on the volatility spill-over between the euro–US dollar and US dollar–yen currency pairs across the five trading regions: Asia, Asia–Europe overlap, Europe, Europe–America overlap and America. Modelling the interaction between returns and volatility in an autoregressive five-equation system, we find evidence that depreciation of the US dollar against the yen has a greater impact on the US dollar–yen volatility spill-over than appreciation in the subprime crisis period. Appreciation and depreciation of the US dollar against the euro does not appear to have an asymmetric effect on the euro–US dollar volatility spill-over. Our results support the notion that the yen may have been preferred to the euro as a ‘safe-haven’ currency relative to the US dollar during the subprime crisis period.     

A regime-switching analysis of pass-through

We empirically investigate how various economic factors affect the changes in the pricing policies of exporters, in particular changes in the exchange rate pass-through. Assuming exporters set prices following either a high or a low pass-through pricing policy, and assuming that the transition probabilities between these pricing policies depend on market concentration, exporting country??s market share and monetary stability, we estimate a Markov regime-switching model, using data we have collected on imported cars to the United States. Our findings show that the ??low pass-through?? regime is characterized by: lower exchange rate pass-through, low response to misalignments in the firm??s relative price, low volatility of exogenous shocks, and higher duration. When we decompose the changes in the pass-through in our sample, we find that monetary stability has been the most important factor behind the decline in the pass-through. Monetary stability explains more than 50% of the decline in the exchange rate pass-through, while country market share and market concentration explain about 25 and 10%, respectively.     

Does exchange rate volatility deter Japan-China trade? Evidence from pre- and post-exchange rate reform in China

This paper is an empirical investigation of the effect of RMB-JPY volatility on Japan-China trade with a special emphasis on the impacts of the reform of the RMB exchange rate regime implemented on July 21, 2005. We estimated two types of volatility measures (one based on the ARCH model and the other the usual standard deviation) utilizing daily data from Jan. 2002 through Dec. 2011 and examined both short-run and long-run effects of this volatility on exports of each country to the other with an ARDL approach. The results indicate that Japan's exports to China are not affected by the exchange rate volatility, but China's exports to Japan are negatively influenced during the reform period. Furthermore, the level of the exchange rate has no influence on Japanese exports, but it has a significant impact on Chinese exports. This asymmetric result may be due to differences in the depth of financial markets and in the maturity of exporters of the two countries.     

Anomaly in China＇s Dollar-RMB

Newly-established data on onshore deliverable US dollar-RMB forwards and the Shanghai lnterbank Offered Rate from Oetober 2006 to April 2009 reveal significant violations of covered interest rate parity. This paper explains the cause of this anomaly. Deviations in the forward market are caused by an increase in US dollar-to-RMB conversion restrictions. Given that Chinese monetary authorities want to prevent market participants from taking advantage of the predictable appreciation of the RMB, China＇s State Administration of Foreign Exchange has to tighten up the control on US dollar-to-RMB conversions. Under the tightened conversion restrictions, similar deviations will resurface in the forward market whenever hot money inflow increases. One way to avoid covered interest rate parity violations in the forward market is to decrease hot money inflow into China by maintaining a stable and credible exchange rate policy.     

Exchange Rate Regimes: Middling Through

Abstract

The appropriate exchange rate regime, in the context of integration of currency markets with financial markets and of large international capital flows, continues to be a policy dilemma. It is found that the majority of countries are moving towards somewhat higher exchange and lower interest rate volatility. Features of foreign exchange (forex) markets could be partly motivating these choices. A model with noise trading, non-traded goods and price rigidities shows that bounds on the volatility of the exchange rate can lower noise trading in forex markets; decrease fundamental variance and improve real fundamentals in an emerging market economy (EME); and give more monetary policy autonomy. Central banks prefer secret interventions where they have an information advantage or fear destabilizing speculation. But in the model discussed in this article, short-term pre-announced interventions can control exchange rate volatility, pre-empt deviations in prices and real exchange rates, and allow markets to help central banks achieve their targets. The long-term crawl need not be announced. In conclusion, the regime's applicability to an EME is explored.     

Deviations from long-run equilibria and probabilities of devaluations: An empirical analysis of Danish realignments

Deviations from Long-Run Equilibria and Probabilities of Devaluations — An Empirical Analysis of Danish Realignments. — The probabilities of realignments between the Danish krone and the D-mark are investigated for the 1979–1995 period. Two multivariate systems are estimated. In the I (1) systems, the deviations from the cointegration relations are used as explanatory variables when determining the probabilities of exchange rate changes. It is found that real imbalances in the economy have to a large extent determined the probabilities of central parity changes. Furthermore, the probabilities of central parity changes have been significantly lower after 1983.     

The Chinese economies in global context: The integration process and its determinants

The linkages between the People's Republic of China and the other Chinese economies of Hong Kong and Taiwan are assessed, and compared against those with Japan and the US. We first characterize the time series behavior of three criteria of integration, namely real interest parity, uncovered interest parity, and relative purchasing power parity. There is evidence that these parity conditions tend to hold over longer periods between the People's Republic of China and all other economies, although they do not hold instantaneously. Overall, the magnitude of deviations from the parity conditions is shrinking over time. Amongst all, however, Hong Kong exhibits indications of a more advanced level of integration with the mainland. We also find that evidence is surprisingly positive for integration with the US. We then turn to examining the determinants of the degree of integration. Regression results suggest that the degree of financial and real integration depend upon the extent of capital controls, foreign direct investment linkages as well as exchange rate volatility. J.

Addressing International Empirical Puzzles: the Liquidity of Bonds

Models that assume bonds denominated in different currencies are perfect substitutes can not explain certain empirical puzzles: the exchange rate volatility puzzle is that these models can not explain the observed volatility in real and nominal exchange rates; the Backus-Smith puzzle is that these models can not explain the observed low correlation between real exchange rates and the ratio of home to foreign consumption; the Backus-Kehoe-Kydland puzzle is that these models can not explain the observed low correlation between home and foreign consumption; and finally, the uncovered interest parity puzzle is that these models can not explain the observed deviations from that parity. These long standing puzzles make the models harder to defend. In this paper, we present a symmetric two country portfolio balance model in which home and foreign bonds are imperfect substitutes for money in each country’s transactions technology; this of course makes home and foreign bonds imperfect substitutes for each other. Our calibrated model is capable of addressing the Backus-Smith puzzle and the Backus-Kehoe-Kydland puzzle. It does not fully resolve the exchange rate volatility puzzle, but it makes some headway. And finally it generates deviations from uncovered interest parity, though by some estimates these deviations are not large enough to be consistent with the data.     

Renminbi Derivatives： Recent Development and Issues

This study reviews the developments in the onshore and offshore renminbi derivatives markets. The onshore market has seen a rapid build‐up in the market infrastructure and price discovery mechanism in the past year, with empirical evidence suggesting that its pricing is increasingly determined by financial fundamentals, such as the covered interest rate parity. However, the growth of the market has been restrained by restrictions on the participant base, limited variations in the RMB/US$ exchange rate, market participants’lack of technical capacity and experience, and inadequate supporting financial market infrastructure. The non‐deliverable forward (NDF) market, concentrated in Hong Kong and Singapore, is more developed, but has the drawback that its pricing is not tied to financial fundamentals. The comparison between onshore and offshore markets suggests that two issues are of particular importance for future derivatives market development in China: the balance between regulation and development, and the relationship between onshore and offshore markets.     

Exchange rate exposure of sectoral returns and volatilities: Evidence from Japanese industrial sectors

Most studies of exchange rate exposure of stock returns do not address three relevant aspects simultaneously. They are, namely: sensitivity of stock returns to exchange rate changes; sensitivity of volatility of stock returns to volatility of changes in foreign exchange market; and the correlation between volatilities of stock returns and exchange rate changes. In this paper, we employ a bivariate GJR-GARCH model to examine all such aspects of exchange rate exposure of sectoral indexes in Japanese industries. Based on a sample data of fourteen sectors, we find significant evidence of exposed returns and its asymmetric conditional volatility of exchange rate exposure. In addition, returns in many sectors are correlated with those of exchange rate changes. We also find support for the “averaged-out exposure and asymmetries” argument. Our findings have direct implications for practitioners in formulating investment decisions and currency hedging strategies.     

Surfing the waves of globalization: Asia and financial globalization in the context of the trilemma

Using the “trilemma indexes” developed by Aizenman et al. (2010) that measure the extent of achievement in each of the three policy goals in the trilemma—monetary independence, exchange rate stability, and financial openness—we examine how policy configurations affect macroeconomic performances, with focus on the Asian economies. We find that the three policy choices matter for output volatility and the medium-term level of inflation. Greater monetary independence is associated with lower output volatility while greater exchange rate stability implies greater output volatility, which can be mitigated if a country holds international reserves (IR) at a level higher than a threshold (about 20% of GDP). Greater monetary autonomy is associated with a higher level of inflation while greater exchange rate stability and greater financial openness could lower the inflation rate. We find that trilemma policy configurations affect output volatility through the investment or trade channel depending on the openness of the economies. Our results indicate that policy makers in a more open economy would prefer pursuing greater exchange rate stability while holding a massive amount of IR. Asian emerging market economies are found to be equipped with macroeconomic policy configurations that help the economies to dampen the volatility of the real exchange rate. These economies’ sizeable amount of IR holding appears to enhance the stabilizing effect of the trilemma policy choices, and this may help explain the recent phenomenal buildup of IR in the region.     

The Effect of the Exchange Rates on Investment in Mexican Manufacturing Industry

This paper, considering revenue and cost exposure channels, investigates the effects of exchange rate on fixed capital investment in Mexican manufacturing sector over 1994–2003. We find that i) currency depreciation has a positive (negative) effect on fixed investment through the export (import) channel; ii) exchange rate volatility impacts mostly export oriented sectors; iii) the sensitivity of investment to exchange rate movements is stronger in non-durable goods sectors and industries with low mark-up ratios.

Asymmetric effects of the exchange rate on domestic corporate goods prices

This paper empirically examines whether there are asymmetric effects of the exchange rate on domestic corporate goods prices when the exchange rate is more volatile. To identify different volatilities in the exchange rate, we employ a threshold regression model. In other words, we define exchange rate volatility as a threshold variable. By using monthly data from Japan, we estimate a threshold parameter and calculate its confidence interval by following Hansen (2000). The results substantiate that the degree of exchange rate pass-through to the aggregated corporate goods price index is higher and more gradually adjusted in a higher exchange rate volatility regime. Furthermore, such asymmetric relationships are clearly found in three disaggregated corporate goods prices: petroleum and coal products, nonferrous metals, and chemicals and related products.     

Volatility spillover between the RBI’s intervention and exchange rate

This study examines the effectiveness of the Reserve Bank of India’s (RBI) intervention policy in the foreign exchange market. An attempt is made to capture volatility spillovers between the RBI’s intervention and exchange rate. The results indicate that the past volatility of intervention has a positive impact on the present volatility of the exchange rate. Similarly the past volatility of the exchange rate, increases the present volatility of intervention. The volatility of the exchange rate is more sensitive to its past shock than the past shock of an intervention. Similarly, the volatility of intervention is more sensitive to the past volatility of exchange rate compared to the past volatility of intervention.     

THE IMPACT OF EXCHANGE RATE MOVEMENTS ON FOREIGN DIRECT INVESTMENT: MARKET‐ORIENTED VERSUS COST‐ORIENTED

This paper examines the impact of exchange rate movements on foreign direct investment (FDI). We first employ a real options model to show that while the depreciation of a host country's currency tends to stimulate FDI activity of cost‐oriented firms, the depreciation tends to deter FDI activity for market‐oriented firms. With industry panel data on Taiwan's outward FDI into China over the period 1991–2002, our empirical findings indicate that the exchange rate level and its volatility in addition to the relative wage rate have had a significant impact on Taiwanese firms’ outward FDI into China. In general, the empirical results are consistent with the prediction of the theory. Our results reveal that the relationship between exchange rates and FDI is crucially dependent on the motives of the investing firms. Without considering this fact in an empirical model, the testing results might suffer from aggregations bias.     

Real financial market exchange rate volatility and portfolio flows

This paper studies the relationship between real financial market exchange rate volatility and US cross-border equity flows. We found strong evidence that causality goes from real financial market exchange rate volatility to equity flows. According to our results, real financial market exchange rate volatility negatively influences purchases of foreign equity. This finding is in line with the portfolio optimization theory. The impact of real financial market exchange rate volatility on sales of foreign equity is also negative. This result can be explained by the theory of behavioral finance which states that investors are reluctant to realize losses of their portfolios. This is why investors decrease sales of assets when riskiness of the assets increases. The impact of real financial market exchange rate on net purchases of foreign equity is positive. It follows from these results that sales of foreign equity decrease more strongly than purchases of foreign equity when riskiness of foreign assets increases.     

Exchange Rate Expectations,the Forward Exchange Rate Bias and Risk Premia in Target Zones

Expected rates of depreciation within the target zone for the exchange rates of four Nordic countries during 1979–1989 are estimated. Combining these with expected rates of devaluation estimated by Edin and Vredin (1993) we obtain time-series of the overall expected exchange rate change. We can thus construct time-series of foreign exchange risk premia and expectational errors, following which we decompose the forward exchange rate bias into portions attributable to expectational errors and/or risk premia. The conclusion is that time-varying risk premia appear to be the dominant cause of deviations from uncovered interest parity while the role of expectational errors is less clear.
