Global Financial Market Linkages
International Economic Integration
International economic integration refers to the extent and strength of real- sector and financial-sector
linkages among national economies. Real-sector linkages occur through
the international transactions in goods and services while the
financial-sector linkages occur through international transactions in
financial assets.
Sources for Integration
— To seek new markets.
— To seek new supplies of raw materials.
— To gain new technologies.
— To gain production efficiencies.
— To avoid political and regulatory obstacles.
— To reduce risk by diversification.
Henry Lowenfeld, 1909
“It
is significant to see how entirely all the rest of the Geographically
Distributed stocks differ in their price movements from the British
stock. It is this individuality
of movement on the part of each security, included in a
well-distributed Investment List, which ensures the first great
essential of successful investment, namely, Capital Stability.”
From: Investment and Exact Science, 1909.
Diversification: 18th Century Mutual Funds
— In the portfolio construction the fund “will observe as much as possible an equal proportionality”
— “Because
nothing is completely certain, but subject to fluctuations, it is
dangerous to allocate all capital to a single security”
— “Nobody
will have reason to believe that all securities will stop paying off at
the same time thereby losing the entire invested capital”
Globalization and Financial Linkages
— Common wisdom is that globalization and integration of markets accentuates financial linkages (correlations)
◦ Business cycle synchronization
◦ Policy coordination
◦ Coordination of institutions
◦ Decrease in “home bias” of investors
◦ Globalization of firms
— Globalization and integration also allows country specialization
— Expansion of investment opportunities
— Lowering of transactions costs
◦ Trade where costs are lowest
◦ Competition among exchanges
◦ Cross-listing / depository receipts / global shares
— Cost of capital / Expected returns
— Change in covariance structure of returns affecting portfolio risk / benefits of diversification
What is the overall effect?
— Decrease in expected returns
— Higher correlation between asset markets
— More markets for investment
— Increase in the types of marketed securities
— Potential synchronization of business cycles
— Increased policy coordination
Net effect?
The Role of Emerging Markets
— Expand the investment opportunity set
— Are imperfectly correlated with existing markets
— What
is the relative contribution of changing correlations and evolution in
the investment opportunity set for diversification benefits?
Globalization: How do Correlations Change?
— Does location of a firm matter?
— Industry membership may become more important
— What happens to residual risk?
Emerging Equity Markets
— Increased industry importance
— Countries become less important
◦ Why does it still matter?
— Residual risk is increasing: cost of not being diversified is going up
Global Linkages of Other Markets
— Bond markets
◦ Interest rate correlations have increased in Europe before EMU
◦ Reduction of Bond market diversification
— Real estate markets
◦ Non-tradable goods
◦ But linked through
– business cycle correlations
– Interest rate correlations
– exchange rate correlations
Bottom Line: International Diversification Does Not Work as it Used to...
• Trade barriers disappear (NAFTA, EU, ASEAN, etc.)
• Globalization of Business Enterprises,
• Wave of intra-industry M&A (incl. cross-border M&A)
“…active
portfolio managers will have increasing difficulty adding value by
using a top-down strategy through European country allocation.”
(Freiman, 1998)
International Financial Linkages - Summary –
— There is reason to believe that international financial linkages are becoming stronger.
◦ World is not yet a global place
— Expansion of investment opportunity set should give some compensation for investors who seek diversification
◦ Number of markets
◦ Expansion of tradable assets: new markets / securities
