Unconventional monetary policy and the dollar–euro exchange rate: first results from time-series analysis

This article examines the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (Fed) and the European Central Bank (ECB). To that end, we make use of time-series analysis to obtain a reasonable long-run and short run representation of the data generation process and use dummy variables to study how announcements about monetary policy changes can affect the USD–EUR exchange rate. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused an appreciation of the dollar, while those by the Fed would have caused a depreciation of the dollar.     

News and correlations of CEEC-3 financial markets

We employ DCC-MGARCH models to investigate conditional correlations between six CEEC-3 financial markets. In general, the highest correlations exist between Hungary and Poland in foreign exchange and stock markets. Short-term money markets are somewhat isolated from each other. We find that the associations of CEEC-3 exchange rates versus euro are weaker than those versus the US dollar. The persistence of the effect of shocks on the time-varying correlations is strongest for foreign exchange and stock markets, indicating a tendency toward contagion. In searching for the origins of financial market volatility in the CEEC-3, we uncover some evidence of Granger-causality on the foreign exchange markets. Finally, using a pool model, we investigate the impact of euro area, US, and CEEC-3 news on the correlations. Apart from ECB monetary policy news, we observe no broad effects of international news on correlations; instead, local news exerts an influence, which suggests a dominance of country- or market-specific circumstances.     

Unconventional monetary policy and the dollar–euro exchange rate: further evidence from event studies

New evidence is presented on the impact on the US dollar–euro (USD–EUR) exchange rate of the unconventional monetary policy conducted by the US Federal Reserve (FED) and the European Central Bank (ECB). To that end, we employ an event study approach using daily the USD–EUR exchange rate for the period from 2 January 2007 to 31 January 2015. Our results indicate that the announcement and subsequent implementation of such measures by the ECB would have caused in general an appreciation of the dollar, while those by the FED would have caused a depreciation of the dollar.     

TALKING LESS AND MOVING THE MARKET MORE: EVIDENCE FROM THE ECB AND THE FED

This paper examines and compares the communication strategies of the Federal Reserve and the European Central Bank, and their effectiveness. First, we find that the surprise components of both monetary policy actions and statements have important but differing effects on asset prices, with unexpected communication having a much greater impact on longer‐term interest rates. Second, both the ECB and the Fed have proven to be equally successful in moving their domestic asset prices using either monetary policy or news shocks. However, the response of the American yield curve to the surprise component of Fed's statements is larger than the reaction of the European term structure to ECB's announcements. This result is intimately related to the amplitude of the policy rate cycle that is much larger in the US than in the euro area combined with the bounded support of the news shock. Third, we analyze the cross‐effects and show that the Fed has been more able to move the European interest rates of all maturities than the ECB to move American rates. This finding is tied to the predominance of dollar fixed income assets rather than to an attempt of the ECB to mimic the Fed.     

The impact of foreign macroeconomic news on financial markets in the Czech Republic, Hungary, and Poland

In this paper, we investigate the effects of euro area and US macroeconomic news on financial markets in the Czech Republic, Hungary, and Poland (CEEC-3) from 1999 to 2006. Using a GARCH model, we examine the impact of news on daily returns of 3-month interest rates, stock market indices, exchange rates versus the euro, and the US dollar. First, both US and European macroeconomic news has a significant impact on CEEC-3 financial markets. Second, the process of European integration is accompanied by an increasing importance of euro area news relative to US news. Third, there are country-specific differences: for example, the Czech stock market is relatively more affected by foreign news since the Copenhagen Summit in December 2002. In general, our results support the hypothesis of a deepening euro area influence on the CEEC-3 over time and a corresponding reduction in the relative importance of US shocks.     

How the ECB and the US Fed set interest rates

Monetary policies of the European Central Bank (ECB) and US Fed can be characterized by ‘Taylor rules’, that is both central banks seem to be setting rates by taking into account the ‘output gap’ and inflation. We also set up and tested Taylor rules which incorporate money growth and the euro–dollar exchange rate, thereby improving the ‘fit’ between actual and Taylor rule based rates. In general, Taylor rules appear to be a much better way of describing Fed policy than ECB policy. Simulations suggest that the ECB's short-term interest rates have been at a much lower level in the last 2 years compared with what a Taylor rule would suggest.     

The effectiveness of monetary policy in steering money market rates during the financial crisis

The financial crisis has deeply affected money markets and thus, potentially, the proper functioning of the interest rate channel of monetary policy transmission. Therefore, we analyze the effectiveness of monetary policy in steering euro area money market rates by looking at (i) the predictability of money market rates on the basis of monetary policy expectations and (ii) the impact of extraordinary central bank measures on money market rates. We find that during the crisis money market rates up to 12 months still respond to revisions in the expected path of future rates, even though to a lesser extent than before August 2007. We attribute part of the loss in monetary policy effectiveness to money market rates being driven by higher liquidity premia and increased uncertainty about future interest rates. Our results also indicate that the ECB’s non-standard monetary policy measures as of October 2008 were effective in addressing the disruptions in the euro area money market. In fact, our estimates suggest that non-standard monetary policy measures helped to lower Euribor rates by more than 80 basis points. These findings show that central banks have effective tools at hand to conduct monetary policy in times of crises.     

Do China and oil exporters influence major currency configurations?

This paper analyses the impact of the shift away from a US dollar focus of systemically important emerging market economies (EMEs) on configurations between the US dollar, the euro and the yen. Given the difficulty that fixed or managed US dollar exchange rate regimes remain pervasive and reserve compositions mostly kept secret, the identification strategy of the paper is to analyse the market impact on major currency pairs of official statements made by EME policy-makers about their exchange rate regime and reserve composition. Developing a novel database for 18 EMEs, we find that such statements not only have a statistically but also an economically significant impact on the euro, and to a lesser extent the yen against the US dollar. The findings suggest that communication hinting at a weakening of EMEs’ US dollar focus contributed substantially to the appreciation of the euro against the US dollar in recent years. Interestingly, EME policy-makers appear to have become more cautious in their communication more recently. Overall, the results underscore the growing systemic importance of EMEs for global exchange rate configurations.     

Exchange rates,central bank news and the zero lower bound*

The zero lower bound (ZLB) may restrict the responsiveness of exchange rates to news. A proxy for central bank communication is added as a determinant in a model of exchange rate movements. Two reserve currencies, the British pound and euro, and two currencies of small open economies, the Canadian dollar and Swedish krona, are examined. Reserve currencies are more vulnerable to the ZLB constraint, while the currencies of small open economies become more responsive to foreign central bank announcements. Certain unconventional monetary policy announcements were found to significantly impact exchange rates at the ZLB.     

ECB monetary policy and commodity prices

We assess the impact of ECB monetary policy on global aggregate and sectoral commodity prices over 2001–2019. We employ an SVAR model and separately assess periods before and after the global financial crisis. Our key results indicate that contractionary monetary policy shocks have positive effects on commodity prices during both conventional and unconventional monetary policy periods, indicating the effectiveness of unconventional monetary policy tools. The largest impact is documented on energy (fuel) and food commodities. Our results also suggest that the effect of ECB monetary policy on commodity prices transmits through the exchange rate channel, which influences European market demand.     

‘Talking down monetary policy’ – a note

There is a recent debate about whether ultra-expansionary monetary policy is no longer effective in stimulating demand, a concern often voiced in the euro area in light of persistently low and even negative inflation. As a response, the European Central Bank (ECB) warns against ‘talking down monetary policy’ (ECB Vice-President Vítor Constâncio, 2016). This note uses a textbook model of optimal monetary policy to study a situation in which the public misperceives the interest rate elasticity of aggregate demand, which reflects policy effectiveness. We show that as a result of underestimating policy effectiveness demand shocks can no longer be stabilized perfectly, thus resulting in inefficient inflation and output dynamics. In the presence of misperceptions, a negative demand shock leads to a prolonged period of negative inflation rates.     

Behavioural equilibrium exchange rate and total misalignment: evidence from the euro exchange rate

In the present paper we attempt to investigate whether the nominal exchange rate of the euro against the currencies of the four major trading partners of the eurozone, namely China, Japan, the UK and the USA, converges or not to its equilibrium level. Applying recent unit root and system cointegration techniques in the presence of structural shifts in the data, our results indicate that there exist an equilibrium relationship between each of the euro/yuan, euro/yen, euro/UK pound and euro/US dollar nominal exchange rates and the fundamentals defined by the monetary model. Following these results, our modified Behavioural Equilibrium Exchange Rate model suggests that at the end of the estimated period, the euro/Chinese yuan and the euro/UK pound nominal exchange rates follow an equilibrium process. Our empirical results also imply that the single European currency is considered as overvalued against the US dollar, while it is considered as undervalued against the Japanese currency.     

Explaining the early years of the euro exchange rate: An episode of learning about a new central bank

Many observers were surprised by the depreciation of the euro after its launch in 1999. Handicapped by a short sample, explanations tended to appeal to anecdotes and lessons learned from the experiences of other currencies. Now sample sizes are just becoming large enough to permit reasonable empirical analyses. The model of this paper provides empirical support for the euro exchange rate to be affected by learning. By focusing on euro-area inflation as the key fundamental, the model is structured toward the dynamics of learning about ECB policy with regard to inflation. While a stated target inflation rate of 2 percent existed, it may be that market participants had to be convinced that the ECB would, indeed, generate low and stable inflation. With a prior distribution drawn from the pre-euro EMS experience and updating based upon the realized experience each month following the introduction of the euro, the evidence suggests that it was not until December of 1999 that the market assessed a greater than 50 percent probability that the inflation process had changed to a new regime. From this point on, trend depreciation of the euro ends and further increases in the probability of the new inflation process are associated with euro appreciation versus the US dollar, the British pound and the Japanese yen.     

Bi‐currency versus Single‐currency Targeting: Lessons from the Russian Experience

This paper examines how the 2005 shift in Russian exchange rate policy from US dollar (USD) single‐currency to USD–EUR (euro) bi‐currency targeting has impacted domestic interest rates. The finding show that this policy shift has disconnected Russian interest rates from US dollar‐denominated interest rates, while instead linking them to a synthetic interest rate composed of USD and EUR rates at the same proportion as that of these two currencies in the currency basket against which the ruble's exchange rate is set. The Russian experience shows that while the adoption of bi‐currency targeting may help ensure that domestic interest rates are less dependent on the monetary cycle of a single country, these rates are instead likely to reflect financial developments in all countries whose currencies are included in the currency basket. This insight is likely to be relevant for other countries that pursue basket‐targeting policies.     

Reverse Causality in Global and Intra‐European Imbalances

The paper discusses global current account imbalances in the context of an asymmetric world monetary system. It identifies the USA and Germany as center countries with rising/high current account deficits (USA) and surpluses (Germany). These are matched by current account surpluses of countries stabilizing their exchange rates against the dollar (dollar periphery) and current account deficits of countries stabilizing their exchange rates against the euro or members of the euro area (euro periphery). The paper finds that changes of world current account positions are closely linked to the monetary policy decision patterns both in the centers and peripheries. Whereas in the centers current account positions are affected by monetary policies, in the peripheries exchange rate stabilization cum sterilization matters. In specific, monetary expansion in the USA as well as exchange rate stabilization and sterilization policies in the dollar periphery are found to have contributed to global imbalances.     

Non‐linearities,Business Cycles and Exchange Rates

This paper conjoins the disparate empirical literatures on exchange rate models and monetary policy models, with special reference to the importance of output, inflation gaps and exchange rate targets. It focuses in on the dollar/euro exchange rate, and the differential results arising from using alternative measures of the output gap for the US and for the Euro area. A comparison of ‘in‐sample’ prediction against alternative models of exchange rates is also conducted. In addition to predictive power, I also assess the various models' plausibility as economic explanations for exchange rate movements, based on the conformity of coefficient estimates with priors. Taylor rule fundamentals appear to do as well, or better, than other models at the 1‐year horizon.     

Controllability and Persistence of Money Market Rates along the Yield Curve: Evidence from the Euro Area

Abstract. Controllability of longer‐term interest rates requires that the persistence of their deviations from the central bank's policy rate (i.e. the policy spreads) remains sufficiently low. This paper applies fractional integration techniques to assess the persistence of policy spreads of euro area money market rates along the yield curve. Independently from anticipated policy rate changes, there is strong evidence for all maturities that policy spreads exhibit long memory. We show that recent changes in the operational framework and the communication strategy of the European Central Bank (ECB) have significantly decreased the persistence of euro area policy spreads and, thus, have enhanced the ECB's influence on longer‐term money market rates.     

Macroeconomic News and the Euro/Dollar Exchange Rate

This paper investigates to what extent daily movements in the euro/dollar rate were driven by news about the macroeconomic situation in the USA and the euro area during the first two years of EMU. We examine whether market participants reacted to news in different ways depending on whether the news came from the USA or from the euro area, and whether the news was good or bad. Furthermore, we investigate whether traders' reaction to news has changed over time. We find that macroeconomic news has a statistically significant correlation with daily movements of the euro against the dollar. However, this relationship exhibits considerable time variation. There are indications of asymmetric response, but to different extents at different times. Our results also provide evidence that the market seemed to ignore good news and remain fixated on bad news from the euro area, as often claimed in market commentaries, but only for some time. Finally, we find evidence that the impact of macroeconomic news on the euro/dollar rate was stronger when news switches from good to bad or vice versa.

IS THE VIEW FROM THE EUROTOWER PURELY EUROPEAN? – NATIONAL DIVERGENCE AND ECB INTEREST RATE POLICY

The official view on ECB monetary policy claims that decisions are based on euro zone data and that diverging regional developments are disregarded. To test empirically whether regional developments have an impact on ECB decisions we develop a generalised monetary policy reaction function which allows for an influence of regional divergence. Reaction function estimations and a probit model of interest rate decisions for the first years of the euro area offer some first support for an impact of regional divergence. The results clarify that ignoring a potential national perspective may lead to biased estimates for the ECB reaction function.
