Financial services in an increasingly integrated global financial market

This paper discusses aspects of global financial services. As part of financial globalisation, financial institutions have evolved both nationally and internationally. FDI is becoming an important vehicle for multinational banks to enter developing countries. This in turn is changing the composition of trade in financial services. The experience of regional integration in Europe and the emergence of large multinational European banks signal a new era of global competition and consolidation of financial institutions. Home bias in international financial services is much less where financial integration is taking place. With financial globalisation, one should expect more diversification of ownership of multinational banks around the world, particularly when China and India are now able to have strategic investment in some of the key investment banks around the world. Financial globalisation requires stronger and more effective international institutions as a way of monitoring the activities of multinational financial institutions at both the national and international levels.     

The future and dynamics of global systemically important banks

The purpose of this paper is to analyse some of the issues associated with supervision and regulation of global systemically important banks, G-SIB. The paper highlights the importance of managing liquidity risk and creating a global financial system that can minimise regulatory arbitrage by large financial institutions. The paper argues that, unlike some industries such as the airline industry in which risk has been contained and yet the size and capacity of aircrafts have increased, in the banking system, less progress has been made to contain financial risk and allow large banks to expand their global activities. The paper argues that G-SIB are able to continue remaining large provided that a globally integrated financial system ensures effective global supervision of these large banks. The paper compares the US banking crises in the 19th century and the subsequent emergence of the US Federal Reserve System to the possibility of establishing a world central bank and a global supervisory board. Such new global institutions will have the capacity to reduce regulatory arbitrage, increase effective supervision, reduce systemic and liquidity risk and create a more stable global financial system.     

Systemic risk,macroprudential policy frameworks,monitoring financial systems and the evolution of capital adequacy

This paper analyses various issues that need to be tackled when promoting financial stability, reviewing the progress made in certain key areas and the remaining challenges. It explores the measurement of systemic risk and of individual institutions’ contribution to it. It discusses aspects of macroprudential frameworks, including how the countercyclical capital buffer envisaged in Basel III takes into account the properties of the financial cycle and the strengths and weaknesses of macro-stress tests. It analyses some of the challenges of how best to monitor financial systems and the broader economy in order to detect signs of vulnerability that might lead to future bouts of financial instability and of how to set prudential policy accordingly. And it discusses the evolution of capital adequacy standards and the new emphasis on liquidity standards in international regulation.     

General equilibrium pricing of currency and currency options

This paper presents a consumption-based general equilibrium model for valuing foreign exchange contingent claims. The model identifies a novel economic mechanism by exploiting highly but imperfectly shared consumption disaster with variable intensities which are the concerns to the representative investor under recursive utility. When applied to the data, the model simultaneously replicates (i) the moderate option-implied volatilities; (ii) substantial variations in the risk-neutral skewness of currency returns; (iii) the uncovered interest rate parity puzzle; and (iv) the first two moments of carry trade returns. Furthermore, the model rationalizes salient features of the aggregate stock, government bonds, and equity index options.     

Foreign currency borrowing surrounding the global financial crisis: Evidence from Korea

We present a complete profile of firms’ foreign currency borrowing surrounding the 2007 global financial crisis. Employing extensive data from Korean firms during 2002–2012, we find that foreign currency borrowing is significantly related to firm attributes of export revenues, firm size, tangible assets and asset growth, as well as to macro-level factors. These results offer two important implications. First, macroeconomic factors alone cannot fully explain firms’ foreign currency borrowing. Second and more importantly, these firm attributes are indicative of a lower default probability and larger collateral value, which would not only facilitate borrowers’ access to foreign currency debt markets but also offer lenders a better protective cushion from possible loan defaults in the face of exchange rate changes and information asymmetry on borrowers’ credits. Period wise, asset-related firm attributes have more pronounced effects in the post- than pre-crisis period. We further show that banking regulations following the crisis effectively limit the access to foreign currency borrowing by Korean firms, most significantly by those belonging to large business groups.     

Daily pricing of emerging market sovereign CDS before and during the global financial crisis

In this paper, we study the determinants of daily spreads for emerging market sovereign credit default swaps (CDSs) over the period April 2002–December 2011. Using GARCH models, we find, first, that daily CDS spreads for emerging market sovereigns are more related to global and regional risk premia than to country-specific risk factors. This result is particularly evident during the second subsample (August 2007–December 2011), where neither macroeconomic variables nor country ratings significantly explain CDS spread changes. Second, measures of US bond, equity, and CDX High Yield returns, as well as emerging market credit returns, are the most dominant drivers of CDS spread changes. Finally, our analysis suggests that CDS spreads are more strongly influenced by international spillover effects during periods of market stress than during normal times.     

Countercyclical currency risk premia

We describe a novel currency investment strategy, the ‘dollar carry trade,’ which delivers large excess returns, uncorrelated with the returns on well-known carry trade strategies. Using a no-arbitrage model of exchange rates we show that these excess returns compensate U.S. investors for taking on aggregate risk by shorting the dollar in bad times, when the U.S. price of risk is high. The countercyclical variation in risk premia leads to strong return predictability: the average forward discount and U.S. industrial production growth rates forecast up to 25% of the dollar return variation at the one-year horizon. The estimated model implies that the variation in the exposure of U.S. investors to worldwide risk is the key driver of predictability.     

Crash-neutral currency carry trades

Currency carry trades exploiting violations of uncovered interest rate parity in G10 currencies deliver significant excess returns with annualized Sharpe ratios equal to or greater than those of equity market factors (1990–2012). Using data on out-of-the-money foreign exchange options, I compute returns to crash-hedged portfolios and demonstrate that the high returns to carry trades are not due to peso problems. A comparison of the returns to hedged and unhedged trades indicates crash risk premia account for at most one-third of the excess return to currency carry trades.     

Economies of scope in financial services: A DEA efficiency analysis of the US insurance industry

This paper investigates economies of scope in the US insurance industry over the period 1993–2006. We test the conglomeration hypothesis, which holds that firms can optimize by diversifying across businesses, versus the strategic focus hypothesis, which holds that firms optimize by focusing on core businesses. We analyze whether it is advantageous for insurers to offer both life-health and property-liability insurance or to specialize in one major industry segment. We estimate cost, revenue, and profit efficiency utilizing data envelopment analysis (DEA) and test for scope economies by regressing efficiency scores on control variables and an indicator for strategic focus. Property-liability insurers realize cost scope economies, but they are more than offset by revenue scope diseconomies. Life-health insurers realize both cost and revenue scope diseconomies. Hence, strategic focus is superior to conglomeration in the insurance industry.     

Households’ foreign currency borrowing in Central and Eastern Europe

Foreign currency loans represent an important feature of recent financial developments in CEECs. This might pose a serious challenge for macroeconomic stability. Against this background, we study the determinants of foreign currency loans of households, using data on the behavior of households in nine CEECs. Our results reveal that foreign currency loans are driven by households’ lack of trust in the stability of the local currency and in domestic financial institutions. Moreover, special factors including remittances and expectations of euro adoption play an important role in selected regions. The financial crisis reduced foreign currency borrowing, but there is some indication this effect might be only temporary.     

Globalisation and the role of effective international institutions

Since empirical research has demonstrated that a sound financial system drives economic growth and the reverse causality alone is not causing this relationship, one can well extend this causal relationship to a global financial system and also argue that those factors that are limiting stronger economic growth and financial globalisation are partly related to deficiencies of the current global financial system. In the same way that some studies have argued for the significance of high quality national institutions as a way of addressing some of the national social and economic bottlenecks and also as a way of creating the right environment for sustained economic growth and integration into the global markets, high quality international institutions with adequate mandates and effective executive power can also influence the process of regional and global financial integration. These international institutions can accelerate the process of national institutional reforms. The paper argues that a number of financial barriers limiting financial globalisation have in essence international, regional and national components and hence without a globally coordinated strategy and framework to have parallel reforms at three levels, the limits to financial globalisation may remain for the foreseeable future.     

Globalisation,growth and institutions

We are currently in the second wave of globalisation. Despite the fact that over the past two decades a number of national financial and other barriers have been removed, there are still a number of national, regional and global factors that are slowing down the process of financial globalisation from trickling down to all parts of the world. This paper briefly discusses the process of globalisation and considers the human development index including education as a way of measuring economic growth and financial wealth in different parts of the world. The paper analyses the process of financial globalisation and the way some nations have become the recipients of more foreign capital than others. As a way of seeing the importance of both national and international economic and financial integration as important ingredients for sustained economic growth, the process of financial integration in Europe is analysed as a model for acceleration of the process of globalisation and sustained economic growth in this century. The 21st century is referred to as the Pacific century and hence financial integration in the Asia Pacific region (APEC) could create a new impetus for the EU to increase its internal integration including its fiscal policies as a way of remaining competitive in the global economy.     

International asset pricing models and currency risk: Evidence from Finland 1970–2004

In this paper we investigate whether global, local and currency risks are priced in the Finnish stock market using conditional international asset pricing models. We take the view of a US investor. The estimation is conducted using a modified version of the multivariate GARCH framework of [De Santis, G., Gérard, B., 1998. How big is the premium for currency risk? Journal of Financial Economics 49, 375–412]. For a sample period from 1970 to 2004, we find the world risk to be time-varying. While local risk is not priced for the USA, the local component is significant and time-varying for Finland. Currency risk is priced in the Finnish market, but is not time-varying using the De Santis and Gérard specification. This suggests that the linear specification for the currency risk may not be adequate for non-free floating currencies.     

Conditional risk premia in currency markets and other asset classes

The downside risk capital asset pricing model (DR-CAPM) can price the cross section of currency returns. The market-beta differential between high and low interest rate currencies is higher conditional on bad market returns, when the market price of risk is also high, than it is conditional on good market returns. Correctly accounting for this variation is crucial for the empirical performance of the model. The DR-CAPM can jointly rationalize the cross section of equity, equity index options, commodity, sovereign bond and currency returns, thus offering a unified risk view of these asset classes. In contrast, popular models that have been developed for a specific asset class fail to jointly price other asset classes.     

Speculative capital and currency carry trades

In this paper, we study a two-country general equilibrium model with partially segmented financial markets, where hedge funds emerge endogenously. Empirically, we show that the hedge fund investment strategy predicted by our model, which we call the “risk-adjusted carry trade” strategy, explains more than 16% of the overall hedge fund index returns and more than 33% of the fixed income arbitrage sub-index returns. The flow of new money to hedge funds affects market interest rates, exchange rates, and both the hedge funds’ contemporaneous and expected future returns as predicted by the model.     

International diversification with securitized real estate and the veiling glare from currency risk

This paper analyzes diversification benefits from international securitized real estate in a mixed-asset context. We apply regression-based mean-variance efficiency tests, conditional on currency-unhedged and fully hedged portfolios to account for systematic foreign exchange movements. From the perspective of a US investor, it is shown that, first, international diversification is superior to a US mixed-asset portfolio, second, adding international real estate to an already internationally diversified stock and bond portfolio results in a further significant improvement of the risk-return trade-off and, third, considering unhedged international assets could lead to biased asset allocation decisions not realizing the true diversification benefits from international assets.     

Conflicts of interest,information provision,and competition in the financial services industry

In some markets sellers have better information than buyers over which products best serve a buyer's needs. Depending on the market structure, this may lead to conflicts of interest in the provision of information by sellers. This paper studies this issue in the market for financial services. The analysis presents a new model of competition between banks, where price competition influences the ensuing incentives for truthful information revelation. We also compare conflicts of interest in two different firm structures, specialized banking and one-stop banking.     

Are options redundant? Further evidence from currency futures markets

This paper investigates the impact of the introduction of options on the underlying asset's price formation process, using Geweke feedback measures. We derive the feedback measures from the Deutsche Mark, British Pound, Swiss Franc, Japanese Yen and Canadian Dollar futures and spot prices, before and after the introduction of options for these currency futures. While each currency market maintains some distinct characteristics in the post-option period, a common theme is found: after the option introduction, the instantaneous feedback between spot and futures markets improves drastically. The feedback from the spot to the futures market tends to decrease and remains small. The feedback from the futures market to the spot market tends to decrease as well. These results confirm the dominance of options markets, probably due to their smaller transaction costs. When made available, options assume a leading role for information transmission in currency markets.     

Foreign participation in local currency bond markets

Countries that cannot attract foreigners to invest in their local currency bonds run the risk of currency mismatches that can result in painful crises. We analyze foreign participation in the bond markets of over 40 countries. Bond markets in less developed countries have returns characterized by high variance and negative skewness, factors that we show are eschewed by U.S. investors. While results based on a three-moment CAPM indicate that it is diversifiable idiosyncratic risk that U.S. investors shun, our analysis suggests that countries can improve foreign participation by reducing macroeconomic instability.     

The time difference effect of a measurement unit in the lead-lag relationship analysis of Korean financial market

This paper investigates Korean financial markets for the study of market microstructure of price discovery in the KOSPI 200 stock index and its related derivatives markets using different time-interval price data. The Granger causality test and vector error correction model are used to analyze the empirical relationship between markets. The lead-lag relationship between the KOSPI 200 stock index and its derivatives markets can be supported by the trading cost hypothesis and leverage effect hypothesis. This paper also shows the congruent lead-lag results in various time-intervals, but as the time-interval becomes large, more information loss and spurious results are induced. The correlations among 1-minute data, 5-minute data, and 10-minute data are significant under a 1% significance level, however, in the case of 60-minute data, the correlations with any other time-interval data are not significant. The 60-minute data even have negative correlations with others. These results are consistent regardless of the raw data or the innovation data. Therefore, we can conclude that the previous research using the 60-minute data due to an insufficiency of trading volume can be biased considerably.
