THE TRANSITION TO A SINGLE INSURANCE MARKET IN THE EUROPEAN UNION

Abstract: The European single insurance market incorporates the member stales of the European Union (EU). The legal framework for the market was enacted on June 30, 1994. The framework provides, above all, for a closely integrated supervisory (regulatory) system, a single license for the whole market and single home country control. Currently, some significant obstacles are slowing the realization of the European single insurance market, while several important economic policy and public interest questions remain to be answered.     

MEASURING THE COST OF CAPITAL IN AN INTERNATIONAL CAPM FRAMEWORK

This paper can be viewed as extending the traditional CAPM framework in two important ways. The first expands the concept of the market portfolio to include international securities. The second extends the definition of systematic risk to include currency risk.
What becomes clear in estimating the cost of capital for an international asset is that both extensions have become necessary if the traditional CAPM is to remain relevant. International markets have become increasingly integrated over the past two decades and so all assets might now be considered "international" and priced accordingly. The inclusion of the currency risk factor is not an ad hoc addition to the CAPM but rather results quite naturally from the fact that foreign returns need to be converted into a domestic currency.
Based on an examination of 18 companies, the article shows that the use of a broader market portfolio will tend to lower the estimated cost of capital for most firms, but in some cases could actually raise it. (In the case of Singapore Airlines, for example, the currency risk factor adds substantially to the cost of capital, while materially reducing it in the case of Nestlé.) Using a simple regression, the authors also attempt to show how the specifics of a particular company—for example, the currencies that are part of their cost/ revenue structure—determine the impact of currency risk on the cost of capital.

Valuation of American options on foreign currency

Pricing models for American call and put options on foreign currency are derived herein. These models are used to investigate the efficiency of the market for foreign currency options. The evidence presented here indicates that market prices for these options deviate substantially from their corresponding model prices. In addition, it is shown that a hedging strategy executed at transaction prices can be used to translate an observed deviation of market from model prices into positive excess profits. However, these profits are eliminated if the strategy is executed at bid and offer prices.     

Global Banks and Synthetic Funding: The Benefits of Foreign Relatives

This paper examines the effect of dislocations in foreign currency (FX) swap markets (“CIP deviations”) on bank lending. Using data from UK banks we show that when the cost of obtaining swap-based funds in a particular foreign currency increases, banks reduce the supply of cross-border credit in that currency. This effect is increasing in the degree of banks' reliance on swap-based FX funding. Access to foreign relatives matters as banks employ internal capital markets to shield their cross-border FX lending supply from the described channel. Partial substitution occurs from banks outside the UK not affected by changes in synthetic funding costs.     

Foreign exchange and lost opportunity in the US Department of Defense

This paper examines US Department of Defense (DoD) foreign exchange rate exposure in light of the government’s prohibition against foreign currency hedging. Using data from the United States Air Force and Monte Carlo simulation, we evaluate whether the use of forward foreign exchange contracts or currency options might reduce the financial impact of currency fluctuation. The results strongly indicate that these alternatives outperform the current method for dealing with foreign currency exposure in the DoD. Using forward contracts, expected cost reductions are on the order of 3.5% of current outlays. For options, expected cost reductions increase to 6.4% thereby defining an upper bound of 2.9% on acceptable option premium levels.     

Empirical evidence on payment media costs and switch points

This paper recovers micro cost schedules of consumers’ payment instruments from aggregate transaction costs. We assume that only two moments of the size distribution of payments matter: the number and volume of transactions. These variables explain the transaction costs of currency and debit card payments with much precision for a representative 1998 sample of Dutch retailers. The results imply that low fixed transaction costs favor currency for small transactions, while low variable transaction costs favor debit card payments for large transactions. The switch point is 30 Euros, but including the hidden costs of currency would lower it to 13 Euros.     

Efficiency Tests of the Foreign Currency Options Market

Based on a new options transactions data base from the Philadelphia Stock Exchange Foreign Currency Options Market, this paper examines the importance of the effect of nonsynchronous prices and transaction costs on the usual option market efficiency tests. The tests conducted are based on the transaction cost adjusted early exercise and put-call parity pricing boundaries applicable to the American foreign currency options market. The test results show that the put-call parity boundary tests are sensitive to both nonsynchronous prices and transaction costs. The early exercise boundary tests are sensitive to transaction costs but are not very sensitive to simultaneity of the option price and the underlying spot price. Under the no-transaction costs scenario, a large number of early exercise boundary violations is found even when simultaneous spot and option prices are used. These violations disappear when actual transaction costs are taken into account.     

Reducing reporting risk: Designating foreign currency forward contracts as cash flow hedges

We present an example that compares the effects on earnings of designating a foreign currency forward contract as either a cash-flow or fair-value hedge of a foreign currency denominated receivable. Entities engaging in exchange transactions not denominated in their functional currency frequently enter into foreign currency forward contracts in order to mitigate their foreign exchange rate risk exposure. The aggregate effect on earnings of the transaction gain or loss on the foreign currency receivable and the gain or loss on the forward contract is known on the date the forward contract is initiated. The effect on each period’s earnings during the term of a forward contract designated as a cash-flow hedge is also known on the date the contract is initiated; whereas the effect on each periods’ earnings from a fair-value hedge cannot be determined until the respective balance sheet dates. Therefore, designating forward contracts as cash-flow hedges may suppress volatility in reported earnings compared to designating forward contracts as fair-value hedges. In addition, the reporting risk (the amount of uncertainty surrounding the pending measure of an item to be reported in the financial statements) is lower when a forward contract is designated as a cash-flow hedge relative to designating it as a fair-value hedge. This suggests foreign currency forward contracts designated as cash-flow hedges are more consistent with the purpose of hedge accounting: to mitigate the effects on earnings of applying different measurement criteria for the hedge and the hedged item.     

Persistence of dollarization after price stabilization

Credit contracts in developing countries are often denominated in foreign currencies, even after many of these economies succeeded in controlling inflation. This paper proposes a new interpretation of this apparent puzzle based on the demand for insurance against real shocks: the fact that devaluations occur more frequently in adverse states of the world provides a motive for holding dollar assets. This approach implies a complementarity between the optimal monetary policy and the currency denomination of contracts. When a large proportion of liabilities is denominated in a foreign currency, the optimal exchange rate volatility is low, which reinforces the demand for dollar assets.     

A METHOD FOR ESTIMATING GLOBAL CORPORATE CAPITAL COSTS: THE CASE OF BESTFOODS

The financial management practices of many multinational corporations are at odds with both financial theory and the strategic case for global expansion. Despite the weight of academic literature, many financial executives still cling to ad hoc rules of thumb that discourage value-enhancing global growth. In particular, they tend to require large risk premiums for making foreign investments while ignoring the diversification benefits of such investments for their shareholders.
This article presents a practical method for estimating the cost of capital for use by multinationals both in evaluating foreign investment opportunities and in measuring the ongoing performance of overseas business units. The method represents a kind of "hybrid" version of the global CAPM—one that attempts to reconcile some of corporate executives' concerns about the distinctive risks of foreign investment with the finance theorist's portfolio perspective and reliance on capital market information. More specifically, the framework uses information from capital markets to determine the appropriate risk premiums for currency and sovereign risks associated with each country in an MNC's portfolio. But, at the same time, these risk premiums are partly offset by taking account of any diversification benefits that foreign investment provides for the firm's shareholders.
The method is illustrated using the case of Bestfoods, a Fortune 200 company with extensive overseas operations that recently adopted the method. For the purpose of evaluating new projects, Bestfoods produces quarterly updates of its cost-of-capital estimates for each country in which it has (or expects to have) major operations. For evaluating the ongoing performance of each country business unit, the relevant cost of capital is calculated annually (at the beginning of each fiscal year).     

Secondary currency: An empirical analysis

Many cases exist of multiple currency usage throughout history. As two leading examples, secondary currencies were widespread during both the Great Depression in the United States and the 2002 recession in Argentina. What are the determinants of multiple currency usage and what is the effect on economic activity? Both issues are empirically addressed using individual-level surveys collected by the authors in Argentina during 2002 and 2003. The evidence supports the theoretically predicted determinants of secondary currency acceptability put forth in monetary theory. In particular, findings show that the acceptability of the secondary currency increases when the supply of national currency is low, the relative transaction cost of the secondary currency is low, and the individual trading technologies are less effective. Moreover the acceptability of the secondary currency has real effects on economic activity. Among those who use the secondary currency the monthly income gain is more than 15% of the average Argentine's monthly income. Excluding trades of used goods, this amounts to a 0.6% increase in GDP.     

EMPIRICAL TESTS OF THE EFFICIENCY OF THE CURRENCY OPTION MARKET

Tests of a hedge and a rational boundary of the efficiency of the currency option market are conducted in this study. These tests use transactions data and account for the effects of currency and option bid/ask spreads, synchronization of option prices and underlying exchange rates, market depth, execution lags, and transaction costs. Currency options, unlike domestic stock options, exhibit continuous dividends. The nature of the option and of the data set employed makes the immediate exercise lower bound test one of the purest tests of market efficiency to date. Results reported here indicate no ability to earn abnormal economic or riskless arbitrage profit for the period when these tests are conducted.     

中国外汇储备的安全性研究

外汇储备的安全性关系到我国的金融安全,已成为我国经济发展中亟待研究解决的一个重要问题。我国的外汇储备保持了高于常规水平的规模,外汇储备广义上的安全性处于良好状态,高额外汇储备为金融安全增加了保险系数;而我国外汇储备狭义上的安全性,即外汇储备资产本身的安全却令人担忧,已经为高额的外汇储备付出巨大成本和承担了很高的风险,特别是在美元弱势明显的情况下将要进一步承受巨大的损失风险。同时高额外汇储备也对我国经济发展产生了一系列负面影响和风险,如果从这个意义上来看,我国外汇储备的现状已成为威胁金融安全的一个重要隐患。我国在外汇储备规模方面存在的种种理论误区,导致了政策偏差,使得我国外汇储备处于高风险状况之中。因此,我国外汇储备政策的调整已经刻不容缓。     

Optimal reserve composition in the presence of sudden stops

We analytically derive optimal central bank portfolios in a minimum variance framework with two assets and transaction demands caused by sudden stops in capital inflows. In this model, transaction demands become less important relative to traditional portfolio objectives as debt to reserve ratios decrease. We empirically estimate optimal dollar and euro shares for 23 emerging market countries and find that optimal reserve portfolios are dominated by anchor currencies and, at current debt-to-reserve ratios, introducing transaction demand has a relatively modest effect for most countries. We find that, in general, the dollar acts as a safe haven currency during sudden stops for country specific and global sudden stops, increasing the optimal share of dollar bonds in central bank portfolios. Correspondingly, our model predicts that dollar shares should decline as debt-to-reserve ratios fall, as observed in recent data. We also find that the denomination of foreign currency debt has little importance for optimal reserve portfolios.

Dynamic Volatility Trading Strategies in the Currency Option Market

The conditional volatility of foreign exchange rates can be predicted using GARCH models or implied volatility extracted from currency options. This paper investigates whether these predictions are economically meaningful in trading strategies that are designed only to trade volatility risk. First, this article provides new evidence on the issue of information content of implied volatility and GARCH volatility in forecasting future variance. In an artificial world without transaction costs both delta-neutral and straddle trading stratgies lead to significant positive profits, regardless of which volatility prediction method is used. Specifically, the agent using the Implied Stochastic Volatility Regression method (ISVR) earns larger profits than the agent using the GARCH method. Second, it suggests that the currency options market is informationally efficient. After accounting for transaction costs, which are assumed to equal one percent of option prices, observed profits are not significantly differentfrom zero in most trading strategies. Finally, these strategies offered returns have higher Sharpe ratio and lower correlation with several major asset classes. Consequently, hedge funds and institutional investors who are seeking alternative “marketneutral” investment methods can use volatility trading to improvethe risk-return profile of their portfolio through diversification.

A model of reserves, bank runs, and deposit insurance

A model is presented in which demand deposits backed by fractional currency reserves and public insurance can be beneficial. The model uses Samuelson's pure consumption-loans model. The case for demand deposits, reserves, and deposit insurance rests on costs of illiquidity and incomplete information. The effect of deposit insurance depends upon how, and at what cost, the government meets its insurer's obligation — something which is not specified in practice. It remains possible that demand deposits and deposit insurance are a distortion, and reserve requirements serve only to limit the size of this distortion.     

Fundamentals of corporate currency exposure

I model the relation between corporate currency exposure and fundamental variables like demand elasticities and operating cost structure. The currency location of a firm's operating costs may be in the home currency, the foreign currency, or partially in each. I start with a single-firm setting and extend the results to a competitive setting. The model should help managers better understand the determinants of currency exposure and thus better perform the important tasks of strategic planning and managing enterprise risk.     

THE HEDGING EFFECTIVENESS OF FOREIGN CURRENCY FUTURES

This study provides an initial analysis of the hedging potential of the foreign currency futures markets. Numerous studies exist on the pricing efficiency and hedging effectiveness of the foreign currency forward markets, but little research exists on the foreign currency futures market. An adequate price history has only recently become available to carry out such an investigation. Minimum risk hedges and hedging effectiveness measures are presented for five currencies: the British pound, German mark, Canadian dollar, Japanese yen and Swiss franc. Analysis indicates the relative desirability of positions in futures contracts to minimize the risk of spot currency exposure. Results also show hedging effectiveness increases with the investment horizon.
