Dynamic news effects in high frequency Euro exchange rates

This paper investigates the dynamic, short-run response of Euro exchange rate returns to the information surprise of global macroeconomic announcements. In addition, it advocates a new approach to modelling intraday exchange rate volatility to allow accurate characterisation of reactions. US macroeconomic news generates far more dramatic responses in EUR–USD returns and returns volatility than news on the macroeconomic performance of other countries. However, some Eurozone and German indicators are also important and UK announcements are important for the EUR–GBP rate. The reaction of exchange rate returns to news is very quick and occurs within the first 5 min of the release with very little reaction in the 15 min before and after. These findings show that exchange rates are strongly linked to fundamentals in the 5-min intervals immediately following the data release. Reactions to news are found to vary in magnitude over the sample, with the largest responses to news occurring in response to turning points in the cumulative flow of news.     

Frequency of observation and the estimation of integrated volatility in deep and liquid financial markets

Using two newly available ultrahigh-frequency datasets, we investigate empirically how frequently one can sample certain foreign exchange and U.S. Treasury security returns without contaminating estimates of their integrated volatility with market microstructure noise. Using the standard realized volatility estimator, we find that one can sample dollar/euro returns as frequently as once every 15 to 20 s without contaminating estimates of integrated volatility; 10-year Treasury note returns may be sampled as frequently as once every 2 to 3 min on days without U.S. macroeconomic announcements, and as frequently as once every 40 s on announcement days. Using a simple realized kernel estimator, this sampling frequency can be increased to once every 2 to 5 s for dollar/euro returns and to about once every 30 to 40 s for T-note returns. These sampling frequencies, especially in the case of dollar/euro returns, are much higher than those that are generally recommended in the empirical literature on realized volatility in equity markets. The higher sampling frequencies for dollar/euro and T-note returns likely reflect the superior depth and liquidity of these markets.     

Foreign investment with inflation-linked securities: A natural hedge under Fisher theory?

All foreign holders of U.S. dollars currencies face significant risk of unfavorable currency exchange movements, proportional to the amounts they hold. Some of these risks can be hedged to an extent, but the costs of doing so can be significant, and errors in execution or maintenance of the hedges can cause serious capital losses. Today the vast holdings of China and others creates currency risk on an unprecedented scale. China alone now has a total in excess of a trillion (1 × 10¹²) U.S. dollars, which makes traditional approaches to hedging problematic at best.¹ This paper analyzes the potential hedging effectiveness of investing foreign dollar holdings in U.S. inflation-indexed securities under Fisher's Identity. To the extent that Fisher's Identity and its derivative theories hold, foreign investors can effectively protect the purchasing power of their dollar balances, and earn an assured rate of return. Investment in inflation-indexed securities does not incur the additional expenses that swaps and currency hedges do.     

The impact of economic news on bond prices: Evidence from the MTS platform

Although there is an extensive literature on the impact of macroeconomic announcements on asset prices, the bond market has received less attention than the foreign exchange and equity markets, even less if we consider the European market. This paper uses high-frequency intra-day data over a three-year period to investigate the impact of regularly scheduled macroeconomic news and monetary policy announcements on the returns of the Italian government bond market, the largest one in the Euro-zone. With respect to the previous papers, we use a much broader set of announcements, 68, and a relatively novel dataset (MTS). We find that 25 news have a significant impact on bond returns and that almost all announcements are incorporated into prices within 20 min from the release.     

Foreign news and the structure of co-movement in European equity markets: An intraday analysis

We investigate European equity market volatility responses to foreign macroeconomic surprises. We measure the length of the response and decompose the news effect into direct and indirect components. The latter is induced by volatility transmission between equity markets. We show that 50 percent of the total accumulated impact of US macroeconomic news on the DAX 30 and CAC 40 volatilities is attained after 90 min. We find that the news announcements have significant direct impacts on both European indices but the indirect effect on the French index is stronger than that on the German.     

Emerging market exchange rates during quantitative tapering: The effect of US and domestic news

We analyze the impact of domestic and US-based news announcements of a large set of economic and policy-related fundamentals on the US dollar versus the Turkish lira exchange rate from 2013 to 2016. Since exchange rate behavior is closely related to political trust, we also incorporate the effect of domestic and global political uncertainty, using country indices based on Google search results. Contrary to previous findings, our results reveal that surprises related to the domestic economy have a greater effect on the exchange rate compared to surprises related to the US economy. Most important are the surprises related to domestic inflation and monetary policy, as well as foreign employment, while political uncertainty plays a minor role. There is also an asymmetry in the market response. Bad news about the US economy has more impact than good news, and good news about the domestic economy has more impact than bad news.     

Under-or-overreaction: Market responses to announcements of earnings surprises

We test whether the well-documented market reaction to the announcements of earnings surprises is a manifestation of an investor underreaction or overreaction to extremely good or bad earnings news. Using the market reaction in the three-day period surrounding the announcements of extreme earnings surprises (i.e., SUE) in quarter Q_t as a reference point, we show that firms reporting a high (low) SUE in subsequent quarter Q_t + 1 that confirms their initial quarter Q_t SUE ranking in the same highest or lowest SUE quintiles generate an incremental price run that moves in the same direction as that of the initial SUE. However, the price impact of the confirming SUE signal is weaker than that of its initial SUE. Our findings are robust to the Fama-French three-factor daily regression extended by the momentum factor and a number of other robustness tests. Our result is not consistent with the prevalent view that investors underreact to earnings news. To the contrary, the evidence suggests an initial investor overreaction to extreme SUE signals.     

Currency jumps,cojumps and the role of macro news

This study investigates the impact of macro news on currency jumps and cojumps. The analysis uses intra-day data, sampled at 5-min frequency, for four currencies for the period 2005–2010. Results indicate that currency jumps are a good proxy for news arrival. We find 9–15% of currency jumps can be directly linked to U.S. announcements. Notably, news can explain 22–56% of the 5-min jump returns, and there is evidence that better-than-expected news about the U.S. economy has a negative impact on currency jumps. Cojump statistics suggest close dependencies among European currencies, especially between the euro and the Swiss franc. We also provide evidence on the uncertainty resolution to news.     

The efficiency of the information processing in the Australian dollar market: Price discovery following scheduled and unscheduled news

We jointly investigate the responses of the Australian dollar (AUD) order flow, realized volatility and trading volume to unscheduled Reuters news headline alerts and scheduled macroeconomic news from Australia, Japan, the Eurozone, the U.K., and the U.S. over the period 2 January 2007 to 31 December 2009. We find that Reuters foreign exchange and fixed income market news headlines are important, and those headlines that arrive during the Australian offshore trading hours matter more. Furthermore, the AUD market responded mostly to Australian and U.S. macroeconomic news which have direct relevance for the exchange rate. We also find that better than expected Japanese and Eurozone macroeconomic news elicited a response in the AUD and also that better than expected news from Australia, U.S. and U.K. matter more. Finally, we find that the volume response to news decreases at a slower rate than the volatility response and that order flows for the AUD respond only to scheduled news.     

Central bank announcements of asset purchases and the impact on global financial and commodity markets

We present evidence on the effects of large-scale asset purchases by the Federal Reserve and the Bank of England since 2008. We show that announcements about these purchases led to lower long-term interest rates and depreciations of the U.S. dollar and the British pound on announcement days, while commodity prices generally declined despite this more stimulative financial environment. We suggest that LSAP announcements likely involved signaling effects about future growth that led investors to downgrade their U.S. growth forecasts lowering long-term US yields, depreciating the value of the U.S. dollar, and triggering a decline in commodity prices. Moreover, our analysis illustrates the importance of controlling for market expectations when assessing these effects. We find that positive U.S. monetary surprises led to declines in commodity prices, even as long-term interest rates fell and the U.S. dollar depreciated. In contrast, on days of negative U.S. monetary surprises, i.e. when markets evidently believed that monetary policy was less stimulatory than expected, long-term yields, the value of the dollar, and commodity prices all tended to increase.     

Can dual-currency sovereign CDS predict exchange rate returns?

This paper examines both the time-series and cross-sectional variation in the difference between US dollar and Euro denominated sovereign CDS spreads for a group of Eurozone countries. We find that the spread difference between dual-currency sovereign CDS significantly affects the bilateral exchange rate returns. In addition, the difference could predict the cumulative exchange rate returns up to 10 days. The results strongly suggest that the difference contains important information for the exchange rate dynamics at various phases of the crisis.     

Oil Currency and the Dollar Standard: A Simple Analytical Model of an International Trade Currency

The U.S. dollar is the central reference currency for international trade pricing and the main invoicing currency for primary commodities. This paper links these two observations within a stylized theoretical framework, and shows how to obtain a quantitative estimate of the gain to the U.S. economy when the dollar is a reference currency. With dollar invoicing of primary commodities, U.S. firms bear less exchange rate risk than foreign firms. This asymmetry leads to a dollar standard in international goods pricing. We then derive a simple analytical formula to calculate the gains and find that they are extremely small.     

The high-frequency response of exchange rates and interest rates to macroeconomic announcements

The joint movements of exchange rates and U.S. and foreign term structures over short-time windows around macro announcements are studied using a 14-year span of high-frequency data. In order to evaluate whether the joint effects can be reconciled with conventional theory, the implications of these joint movements for changes in expected future exchange rates and changes in foreign exchange risk premia are deduced. For several real macro announcements, a stronger than expected release appreciates the dollar today, and must either (i) lower the risk premium for holding foreign currency rather than dollars, or (ii) imply net expected dollar depreciation over the ensuing decade.     

FOREIGN EXCHANGE MARKET REACTION TO THE U.S.-CANADA FREE TRADE AGREEMENT

In this paper we investigate the effect of news about the advent of the U.S.-Canada Free Trade Agreement (FTA) on the exchange rate between the Canadian dollar and the U.S. dollar. We find evidence that information flows related to the likelihood of the FTA influenced the volatility of the daily spot rate. In particular, information that increased the likelihood of the FTA subsequently diminished exchange rate volatility. In contrast, information that decreased the likelihood of the FTA subsequently increased exchange rate volatility.     

Determinants of periodic volatility of intraday exchange rates in the Taipei FX Market

Using the periodic GARCH (P-GARCH) model, this paper investigates the cause of the volatility seasonality of intraday Taiwan dollar/U.S. dollar (NTD/USD) exchange rate. We study the intraday volatility of NTD/USD exchange rate by considering impacts from public news arrivals, inventory risk and central bank interventions. The estimation results indicate that news arrivals at the market open may induce traders to adjust their inventory position and result in higher NTD/USD volatility on days with reported central bank interventions.     

Cross-border spillover effects of unconventional monetary policies on Swiss asset prices

Unconventional monetary policies (UMPs) announced by the Federal Reserve, the European Central Bank, the Bank of England and the Bank of Japan exert important spillover effects on asset prices in Switzerland. Using a broad UMP event set and a long-term bond-futures based measure of market anticipation, we show that surprisingly expansionary UMPs lower Swiss government and corporate bond yields, induce the Swiss franc to appreciate, and dampen Swiss equity prices. Four extensions provide further insights. First, the estimated effects are strongest for announcements by the ECB. Second, the impact on government bonds is largest for bonds with residual maturities of 7–10 years. Third, the impact of foreign UMP shocks on exchange rates and Swiss bond yields is less pronounced after the introduction of the minimum rate of 1.20 Swiss franc per Euro by the Swiss National Bank on September 6, 2011, indicating that domestic monetary policy action partially affects the impact of external monetary shocks on domestic financial markets. Fourth, the sign of spillover effects differs for positive and negative UMP surprises, but their strength does not.     

International Transmission of U.S. Monetary Policy Shocks: Evidence from Stock Prices

This paper analyzes intraday changes in firm‐level equity prices around interest rate announcements to assess the transmission of U.S. monetary policy to the global economy. We document that foreign firms on average are roughly as sensitive to U.S. monetary policy as U.S. firms, although we also find considerable cross‐sectional variation across firms. In particular, foreign stocks in cyclically sensitive industries show stronger responses to interest rate surprises, consistent with a demand channel of policy transmission. In addition, transmission of U.S. policy appears to be stronger to economies with fixed exchange rates. Evidence for a credit channel is weaker.     

The reaction of asset prices to macroeconomic announcements in new EU markets: Evidence from intraday data

We estimate the impact of macroeconomic news on composite stock returns in three emerging European Union financial markets (the Budapest BUX, Prague PX-50, and Warsaw WIG-20), using intraday data and macroeconomic announcements. Our contribution is twofold. We employ a larger set of macroeconomic data releases than used in previous studies and also use intraday data, an excess impact approach, and foreign news to provide more reliable inferences. Composite stock returns are computed based on 5-min intervals (ticks) and macroeconomic news are measured based on the deviations of the actual announcement values from their expectations. Overall, we find that all three new EU stock markets are subject to significant spillovers directly via the composite index returns from the EU, the U.S. and neighboring markets; Budapest exhibits the strongest spillover effect, followed by Warsaw and Prague. The Czech and Hungarian markets are also subject to spillovers indirectly through the transmission of macroeconomic news. The impact of EU-wide announcements is evidenced more in the case of Hungary, while the Czech market is more impacted by U.S. news. The Polish market is marginally affected by EU news. In addition, after decomposing pooled announcements, we show that the impact of multiple announcements is stronger than that of single news. Our results suggest that the impact of foreign macroeconomic announcements goes beyond the impact of the foreign stock markets on Central and Eastern European indices. We also discuss the implications of the findings for financial stability in the three emerging European markets.     

Long memory and fractional integration in high frequency data on the US dollar/British pound spot exchange rate

This paper analyses the long-memory properties of a high-frequency financial time series dataset. It focuses on temporal aggregation and other features of the data, and how they might affect the degree of dependence of the series. Fractional integration or I(d) models are estimated with a variety of specifications for the error term. In brief, we find evidence that a lower degree of integration is associated with lower data frequencies. In particular, when the data are collected every 10 min there are several cases with values of d strictly smaller than 1, implying a mean-reverting behaviour; however, for higher data frequencies the unit root null cannot be rejected. This holds for all four series examined, namely Open, High, Low and Last observations for the US dollar/British pound spot exchange rate and for different sample periods.     

Macroeconomic news announcements and price discovery: Evidence from Canadian–U.S. cross-listed firms

This study employs macroeconomic news announcements as a proxy for new information arrivals and examines their impact on price discovery. We compare the price discovery of 38 Canadian companies listed on the Toronto Stock Exchange (TSX) and the New York Stock Exchange (NYSE) for the period 2004–2011. First, we observe that price discovery shifts significantly during macroeconomic news announcement days. Second, the NYSE becomes more important in terms of price discovery, regardless of the origin of the news. Third, we examine the relation between price discovery and market microstructure variables. After controlling for liquidity shocks, we find that the impact of news announcements persists. Intraday analyses of price discovery on periods surrounding news releases further support these findings. Overall, our findings suggest that there is a difference in information-processing capability of the two markets, with the U.S. market being better at processing information than the Canadian market during macroeconomic news announcements.
