Excess comovements between the euro/US dollar and pound sterling/US dollar exchange rates

ABSTRACT

The aim of this article is to discuss excess comovements of the euro/US dollar and pound sterling/US dollar exchange rates, i.e. we look for comovements of exchange rates which are stronger than implied by the fundamentals. The results of the empirical analysis provide evidence that excess comovements exist for the two exchange rates. A long-run analysis of correlations can verify that a link exists between the correlation dynamics of exchange rates, relative inflation rates, long-term interest rates, economic sentiments and money supply. We find that common movements of money supply, prices and economic sentiments each play a major role in comovements of the exchange rates. From the investigation of the two exchange rates, we conclude that macroeconomic fundamentals can account for the comovement but that common non-fundamental factors also have major significance for the exchange rates.     

RELATIONSHIPS AMONG STRATEGIC COMMODITIES AND WITH FINANCIAL VARIABLES: A NEW LOOK

We examine the comovements among the prices of four strategic commodities that have long, adequate daily series: oil, gold, silver, and copper as a group. We also explore their causal relationships with two commodity-relevant macrofinancial variables: interest and exchange rates as an expanded group to shed some light on the prediction behaviors of those individual commodity prices relative to the selected financial variables. In the expanded group, the selected interest rate can provide a transmission link between commodity prices and the dollar exchange rate. The results and their policy implications are discussed at length . ( JEL C51, E27, Q43)     

Return and volatility transmission between oil prices and oil-exporting and oil-importing countries

This paper provides further evidence of the comovements and dynamic volatility spillovers between stock markets and oil prices for a sample of five oil-importing countries (USA, Italy, Germany, Netherland and France) and four oil-exporting countries (United Arab Emirates, Kuwait, Saudi Arabia and Venezuela). We make use of a multivariate GJR-DCC-GARCH approach developed by Glosten et al. (1993). The results show that: i) dynamic correlations do not differ for oil-importing and oil-exporting economies; ii) cross-market comovements as measured by conditional correlation coefficients increase positively in response to significant aggregate demand (precautionary demand) and oil price shocks due to global business cycle fluctuations or world turmoil; iii) oil prices exhibit positive correlation with stock markets; and iv) oil assets are not a good ‘safe haven’ for protection against stock market losses during periods of turmoil.     

Common trends and common cycles among interest rates of the G7-countries

Both, from a macroeconomic modeling perspective, as well as for a policy point of view, there has recently been a renewed interest in the cyclical and long-run comovement of interest rates. In this paper we re-investigate the long- and short-run comovements in the G7-countries by conducting tests for cointegration, common serial correlation and codependence with nominal and real interest rates, using quarterly data from 1975 to 2010. Overall, we find only little evidence of comovements. Common trends are occasionally observed, but the majority of interest rates are not cointegrated. Although some evidence for codependence of higher order is found in the pre-Euro area sample, common cycles appear to exist only in rare cases. We argue that some earlier, more positive findings are difficult to reconcile due to differing assumptions about the underlying stochastic properties of interest rates. We conclude that they cannot be generalized for all interest rates, time periods, and reasonable alternative estimation procedures.     

Hot Money Flows,Cycles in Primary Commodity Prices,and Financial Control in Developing Countries

Because the U.S. Federal Reserve’s monetary policy is at the center of the world dollar standard, it has a first-order impact on global financial stability. However, except during international crises, the Fed focuses on domestic American economic indicators and generally ignores collateral damage from its monetary policies on the rest of the world. Currently, ultra-low interest rates on short-term dollar assets ignite waves of hot money into Emerging Markets (EM) with convertible currencies. When each EM central bank intervenes to prevent its individual currency from appreciating, collectively they lose monetary control, inflate, and cause an upsurge in primary commodity prices internationally. These bubbles burst when some accident at the center, such as a banking crisis, causes a return of the hot money to the United States (and to other industrial countries) as commercial banks stop lending to foreign exchange speculators. World prices of primary products then collapse. African countries with exchange controls and less convertible currencies are not so attractive to currency speculators. Thus, they are less vulnerable than EM to the ebb and flow of hot money. However, African countries are more vulnerable to cycles in primary commodity prices because food is a greater proportion of their consumption, and—being less industrialized—they are more vulnerable to fluctuations in prices of their commodity exports. Supply-side shocks, such as a crop failure anywhere in the world, can affect the price of an individual commodity. But joint fluctuations in the prices of all primary products—minerals, energy, cereals, and so on—reflect monetary conditions in the world economy as determined by the ebb and flow of hot money from the United States, and increasingly from other industrial countries with near-zero interest rates.     

International macroeconomic dynamics: A factor vector autoregressive approach

In this paper international comovements among a set of key real and nominal macroeconomic variables in the US, UK, Canada, Japan and the Euro area have been investigated for the 1980–2005 period, using a factor vector autoregressive approach. We present evidence that comovements in macroeconomic variables do not concern only real activity, but are an important feature also of stock market returns, inflation rates, interest rates and, to a smaller extent, monetary aggregates. Both common sources of shocks and similar transmission mechanisms explain international comovements, with the only exception of Japan, where the idiosyncratic features seem to dominate. Finally, concerning the origin of global shocks, evidence of both global supply-side and demand-side disturbances is found.     

Have food and financial markets integrated?

This article analyses comovements and discusses possibly greater market integration between aggregate food commodity and stock prices in the period 1990 to 2012. Return correlations, price return distributions, cointegration and Granger-causalities are tested in subsamples on monthly FAO Food Price Index and MSCI World Stock Market Index. Empirical results suggest that while there is only weak indication of greater comovements concurrent with structural changes such as changed agricultural policies, new demand due to growth in emerging markets and energy mandates and the financialization of food markets since the early 2000s, they did start to increase substantially in particular during the financial stress of the Lehman crisis and the Great Recession. While structural changes may have amplified price linkages across markets, results do not suggest that they are the key factors for greater price comovements. Instead, the effects of the late-2000s recession as a time of great economic weakness and uncertainty may have changed concurrently the behaviour of both food and financial market participants, such that different market prices exhibit large comovements.     

A Model of the Australian Housing Market

We build an empirical model of the Australian housing market that quantifies interrelationships between construction, vacancies, rents and prices. We find that low interest rates (partly reflecting lower world long-term rates) explain much of the rapid growth in housing prices and construction over the past few years. Another demand factor, high immigration, also helps explain the tight housing market and rapid growth in rents in the late 2000s. A large part of the effect of interest rates on dwelling investment, and hence GDP, works through housing prices.     

Threshold Dynamics of Short-term Interest Rates: Empirical Evidence and Implications for the Term Structure

This paper studies a nonlinear one-factor term structure model in discrete time. The short-term interest rate follows a self-exciting threshold autoregressive (SETAR) process that allows for shifts in the intercept and the variance. In comparison with a linear model, we find empirical evidence in favour of the threshold model for Germany and the US. Based on the estimated short-rate dynamics we derive the implied arbitrage-free term structure of interest rates. Since analytical solutions are not feasible, bond prices are computed by means of Monte Carlo integration. The resulting term structure captures stylized facts of the data. In particular, it implies a nonlinear relation between long rates and the short rate.     

Common dynamics of nonenergy commodity prices and their relation to uncertainty

The purpose of this article is to improve the empirical evidence on commodity prices in various dimensions. First, we attempt to identify the extent of comovements in 44 monthly nonenergy commodity price series in order to ascertain whether the increase in comovement is a recent term phenomenon. Second, we attempt to determine the role of uncertainty in determining comovements among nonenergy prices in the short run. We diagnose the overall comovement using a dynamic factor model estimated by principal components. A factor-augmented vector autoregressive approach is used to assess the relationship of fundamentals, financial and uncertainty variables with the comovement in commodity prices. We find a greater synchronization among raw materials since December 2003. Since that date, uncertainty has played an important role in determining short-run fluctuations in nonenergy raw material prices.     

Money Demand and Purchasing Power Parity (PPP), in the Republic of South Africa

We have examined empirically two important economic relationships, the Purchasing Power Parity (PPP) and the money demand relationship, among the consumer prices, money, output, interest rates, and the nominal rand/dollar exchange rate of the Republic of South Africa (RSA) for the sample period from 1993 second quarter to 2003 second quarter within the frameworks of co-integration and Error Correction Model (ECM). It is established that the strong version of the PPP including the proportionality and the symmetry hypothesis, is supported. The changes in the rand/dollar exchange rates are influenced by the long term trends in the consumer prices of the RSA and the USA. There also exists a well defined money demand function for this period. The broad money demand is influenced by the consumer prices, the GDP and the interest rates. The short-term interest rates are found to be the own rate of return for broad money and the long-term bond yield is the opportunity cost of holding money. The monetary policy works through the short term interest rates.

     

State prices,liquidity, and default

We show, in a monetary exchange economy, that asset prices in a complete markets general equilibrium are a function of the supply of liquidity by the Central Bank, through its effect on default and interest rates. Two agents trade goods and nominal assets to smooth consumption across periods and future states, in the presence of cash-in-advance financing costs that have effects on real allocations. We show that higher spot interest rates reduce trade and as a result increase state prices. Hence, states of nature with higher interest rates are also states of nature with higher risk-neutral probabilities. This result, which cannot be found in a Lucas-type representative agent model, implies that the yield curve is upward sloping in equilibrium, even when short-term interest rates are fairly stable and the variance of the (macroeconomic) stochastic discount factor is 0. The risk-premium in the term structure is, therefore, a monetary-cost risk premium.

Will euro area house prices sharply decrease?

The long-term euro area house price equilibrium and its short-term dynamics are estimated by means of a panel error correction model. The estimates show that the short-term dynamics are essentially driven by the autoregressive term (persistence), disposable income and mortgage loans, whereas interest rates have little effect. The long-term house price equilibrium is mainly driven on the demand side by disposable income, interest rates, and mortgage loans, whereas costs (mostly land) drive the equilibrium on the supply side. The unprecedented long-lasting boom in house prices from 1997 to 2007 is thus essentially explained by a favourable macroeconomic development caused by the EMU effect and a glut of global savings. The bust phase of euro area house prices began in 2007, and the current house price might return to its equilibrium level in 2014. According to the most realistic scenario, euro area house prices will experience a smooth and soft landing in 2016 and then begin an increasing phase that will be pulled upwards by a higher equilibrium price. However, a deflationary scenario cannot be excluded if the current credit squeeze is not solved, particularly in the peripheral euro area member states.     

Macroeconomic stability and the optimal degree of capital mobility

This paper examines the relationship between capital mobility and the short-term stability of employment and of prices. It looks at the optimal degree of capital mobility to stabilize income. The sources of instability considered are fluctuations of domestic expenditure or absorption, net exports and international interest rate. In this latter case, loans at fixed nominal interest rates and floating rates are analyzed. Fixed and flexible exchange rate regimes are studied.     

Housing prices,stock prices and the US economy

This paper studies the relationship between housing prices, stock prices, interest rates and aggregate output in the US using monthly data from 1993 to 2014. Evidence from causality tests and a variance decomposition procedure suggest that stock prices have a much larger effect on aggregate output in the US economy than do either housing prices or interest rates. Instead, the wealth effect created by changes in stock prices has a relatively large impact on US aggregate output. Separate estimations and variance decompositions for the sample periods 1993–2001, 2002–2008 and 2009–2014 show that the impact of housing prices relative to stock prices has been waning over time.     

Energy price transmissions during extreme movements

This paper investigates price transmissions across European energy forward markets at distinct maturities during both normal times and extreme fluctuation periods. To this end, we rely on the traditional Granger causality test (in mean) and its multivariate extension in tail distribution developed by Candelon, Joëts, and Tokpavi (2013). Considering forward energy prices at 1, 10, 20, and 30 months, it turns out that no significant causality exists between markets at regular times whereas comovements are at play during extreme periods especially in bear markets. More precisely, energy prices comovements appear to be stronger at short horizons than at long horizons, testifying an eventual Samuelson mechanism in the maturity prices curve. Diversification strategies tend to be more efficient as maturity increases.     

The interest elasticity of household savings: a structural approach with German micro data

This paper empirically investigates the effects of changes in the interest rate as well as in the current and expected future consumer price levels on households’ consumption–savings decision. In a structural demand model applied to German consumption data, we use cross-sectional and longitudinal variation in prices and tax rates to construct individual after-tax interest rates and cluster-specific consumer prices. We find that the compensated own-price elasticities for savings as well as consumption are significantly negative, while the theoretical model implications of homogeneity and symmetry must be rejected. Importantly, we estimate the uncompensated interest rate elasticity of savings, in line with the literature, at around zero. Some heterogeneity in this elasticity is found along the savings and wealth distribution. We conclude that short-term policy-induced variation of net returns to savings is expected to have no significant effects on the level of compound savings.     

Model uncertainty and aggregated default probabilities: new evidence from Austria

Understanding the determinants of aggregated corporate default probabilities (PDs) has attracted substantial research interest over the past decades. This study addresses two major difficulties in understanding the determinants of aggregate PDs: model uncertainty and multicollinearity among the regressors. We present Bayesian model averaging (BMA) as a powerful tool that overcomes model uncertainty. Furthermore, we supplement BMA with ridge regression to mitigate multicollinearity. We apply our approach to an Austrian data set. Our findings suggest that factor prices like short-term interest rates (STIs) and energy prices constitute major drivers of default rates, while firms’ profits reduce the expected number of failures. Finally, we show that the results of our model are fairly robust with respect to the choice of the BMA parameters.     

Copper and the Chilean Economy, 1960-98

This paper studies the links between world copper prices and the Chilean economy. The main conclusion is that world copper prices play an important role in short-term economic fluctuations. While many mechanisms may be at work, investment seems to play a major role. During a copper price boom, the higher copper revenues and associated capital inflows create upward pressure on the real exchange rate. In turn the, appreciation of the Chilean peso during the first part of the copper cycle contributes to lower inflation, which could explain why real wages grow more rapidly in this part of the cycle.
