Portfolio capital flows and the US dollar exchange rate: Viewed from the lens of time and frequency dynamics of connectedness

This study uses proprietary data on daily net non-resident portfolio flows to emerging markets to analyse the interconnectedness of non-resident debt and equity portfolio flows under different market conditions. We find that there is less interconnectedness during normal times but increased interconnectedness during periods of uncertainty and stress, suggesting an asymmetry in the spillovers of these portfolio flows. Importantly, we find that shocks in the broad EM US dollar exchange rate are a net transmitter of shocks to debt and equity portfolio flows of EM economies. Our analysis, based on the net directional spillover index, shows that this effect is most pronounced during the COVID-19 pandemic. Furthermore, using a frequency domain approach to connectedness, we find that the broad EM US dollar exchange rate is a net transmitter of shocks to the EM economies’ debt and equity flows, with the impact hitting portfolio capital flows within at least a week to 100 days. Our results suggest that pre-emptive macroprudential policy measures and better risk monitoring can improve the resilience of borrowers and investors in EM economies during times of global shocks, particularly during US dollar appreciations when portfolio flows tend to reverse.     

Net Equity and Debt Flows to Emerging Market and Developing Economies in the Post-Crisis Era

We investigate the determinants of net equity and debt flows into 60 emerging and developing countries during 1986–2012, with a special focus on the period following the onset of the global financial crisis (GFC). Our results controlling for endogeneity show that net equity flows to emerging markets were mostly influenced by global risk factors, while net debt flows were affected by country-specific factors. We further distinguish the factors that were more pronounced in determining net portfolio flows to emerging markets since the GFC. The US real interest rate had significant spillover effects on net equity flows after the GFC. An increase in country’s domestic credit attracted net debt inflows before the GFC, while it was associated with net equity outflows after the GFC. We also find that capital controls moderated net debt flows since the GFC.     

The risk adjusted uncovered equity parity

This paper explores the risk adjusted uncovered equity parity model to investigate a degree of market integration for four Asian emerging markets relative to the U.S., Japan and the U.K. from January 1994 to July 2008. The uncovered equity parity is revised to take into account of market risk in a framework of a portfolio rebalancing model. Evidence was found to strongly support our hypotheses; Market risk is significant in international capital flows between the Asian emerging markets and the developed economies, and it can help explain the failure of a traditional uncovered equity (or interest) parity model. The relationship between returns and an appreciation of the exchange rate are divided between the Asian emerging markets and the developed economies, depending on the direction of capital flows.     

Exchange market pressure in OECD and emerging economies: Domestic vs. external factors and capital flows in the old and new normal

We study the ways domestic and external global factors (such as risk appetite, global liquidity, U.S. monetary policy, and commodity prices) affected the exchange market pressure before and after the global financial crisis, as well as the role of these factors during the Federal Reserve's tapering episode. Utilizing a comprehensive database on capital controls, we investigate whether control measures have a significant impact on mitigating exchange market pressure associated with capital flows [net and gross]. Using quarterly data over the 2000–2014 period and a dynamic panel model estimation, we find that external factors played a significant role in driving exchange market pressure for both OECD countries and emerging market countries, with a larger impact on the latter. While the effect of net capital flows on exchange market pressure is muted, short-term gross portfolio inflows and outflows comprise important factors that account for exchange market pressure. Short-term portfolio flows and long-term foreign direct investment flows have a significant impact on exchange market pressure for emerging market economies and no significant effect for OECD countries. Capital controls seem to significantly reduce the exchange market pressure, although the economic size of this impact is highly dependent on the institutional quality.     

Spillovers of U.S. unconventional monetary policy to emerging markets: The role of capital flows

We employ a structural global VAR model to analyze whether U.S. unconventional monetary policy shocks, identified through changes in the central bank’s balance sheet, have an impact on financial and economic conditions in emerging market economies (EMEs). Moreover, we study whether international capital flows are an important channel of shock transmission. We find that an expansionary policy shock significantly increases portfolio flows from the U.S. to EMEs for almost two quarters, accompanied by a persistent movement in real and financial variables in recipient countries. Moreover, EMEs on average respond to the shock with an easing of their own monetary policy stance. The findings appear to be independent of heterogeneous country characteristics like the underlying exchange rate arrangement, the quality of institutions, or the degree of financial openness.     

Exchange Rates, Equity Prices, and Capital Flows

We develop an equilibrium model in which exchange rates, stockprices, and capital flows are jointly determined under incompleteforeign exchange (forex) risk trading. Incomplete hedging offorex risk, documented for U.S. global mutual funds, inducesthe following price and capital flow dynamics: Higher returnsin the home equity market relative to the foreign equity marketare associated with a home currency depreciation. Net equityflows into the foreign market are positively correlated witha foreign currency appreciation. The model predictions are stronglysupported at daily, monthly, and quarterly frequencies for 17OECD countries vis-à-vis the United States. Correlationsare strongest after 1990 and for countries with higher equitymarket capitalization relative to GDP, suggesting that the observedexchange rate dynamics is indeed related to equity market development.     

International Cross‐Listings and Subsequent Security‐Market Choices: Evidence from ADRs

We study the link between the attributes of American depositary receipt (ADR)‐listed firms and their post‐listing security‐market choices. We find that developed market firms are more likely to issue equity and debt than their emerging market counterparts. Furthermore, we find that large firms are more likely to issue debt and less likely to issue equity. When we examine locations where ADR firms raise their capital, we find that firms originating from countries where the protection of minority shareholders is weak are more likely to issue debt on their home markets and less likely to issue debt on international markets (excluding U.S. markets). Furthermore, ADR firms originating from developed (emerging market) countries are more (less) likely to issue their equity on their domestic markets and less (more) likely to issue equity on international markets (excluding U.S. markets).     

Does the market discipline banks? New evidence from regulatory capital mix

While bank capital requirements permit a bank to freely substitute between equity and subordinated debt, lenders and investors view debt and equity as imperfect substitutes. It follows that, after controlling for the level of regulatory capital, the mix of debt in capital isolates the role that the market plays in disciplining banks. I document that the mix of debt in capital affects bank behavior, but only when investors can impose real constraints. In particular, the mix of debt reduces the probability of failure and future distress for BHC-affiliated institutions (where the investor has control rights through an equity position) and for stand-alone banks before the Basel Accord (when debt issues included restrictive covenants). However, substituting equity for subordinated debt at the bank holding company level or in stand-alone banks since the Basel Accord (where the investor has few protections) only increases the probability of distress and failure.     

全球金融周期与跨境资本流动

本文从全球42个主要的股票市场指数提取全球股票市场因子,作为全球金融周期的代理变量,考察全球金融周期对跨境资本总流入的影响。结果发现:(1)当全球股票市场因子(全球风险规避和不确定性)上升时,跨境资本流入显著下降;(2)一国处于经济繁荣时期,经济增速和利率处于相对较高水平,全球金融周期对资本流入的影响会减弱;(3)一国资本账户开放程度或金融发展水平越高,全球金融周期对资本流入的影响会越强;(4)更具弹性的汇率制度尽管不能完全隔绝全球金融周期的影响,但相比固定汇率制度,可提高一国抵御全球金融周期冲击的能力;(5)美国货币政策冲击是全球金融周期的重要驱动因素,并通过全球金融周期影响跨境资本流动。本文的政策含义在于,一国应夯实经济基本面、采取富有弹性的汇率制度和适当的资本管制措施,以缓解全球金融周期给资本流动带来的冲击。     

The Global CAPM and a Firm's Cost of Capital in Different Currencies

In an integrated global market, a firm's cost of capital expressed in one currency should be consistent with its cost of capital expressed in another currency. This article presents and illustrates a process for estimating consistent costs of capital in different currencies for a U.K. based multinational. In so doing, it uses a simple, easy-to-use version of the global CAPM that attempts to incorporate the effect of uncertain exchange rates by calculating exchange rate "betas." As argued in the previous article, at least part of a company's currency exposure is systematically related to the global market and thus should be treated as a component of the firm's systematic equity risk.
For example, the U.K. firm featured in this article is shown to have an exchange rate beta of 0.20 from the perspective of a U.S. investor. This implies that a 10% return on the global market in U.S. dollars tends to be associated with a 2% change in the U.S. dollar value of the British pound. One interesting consequence of incorporating exchange risk in this fashion is that two firms with identical U.S. global betas and costs of equity will have different expected returns expressed in another currency if they have different exposures to that currency.     

What moves international stock and bond markets?

We study the relation between international mutual fund flows and the different return components of aggregate equity and bond markets. First, we decompose international equity and bond market returns into changes in expectations of future real cash payments, interest rates, exchange rates, and discount rates. News about future cash flows, rather than discount rates, is the main driver of international stock returns. This evidence is in contrast with the typical results reported only for the US. Inflation news instead is the main driver of international bond returns. Next, we turn to the interaction between these return components and international portfolio flows. We find evidence consistent with price pressure, short-term trend chasing, and short-run overreaction in the equity market. We also find that international bond flows to emerging markets are more sensitive to interest rate shocks than equity flows.     

The Capital Structure of PE‐Funded Companies (and How New Debt Instruments and Investors Are Expanding Their Debt Capacity)

The capital structures and financial policies of companies controlled by private equity firms are notably different from those of public companies. The concentration of ownership and intense monitoring of leveraged buyouts by their largest investors (that is, the partners of the PE firms who sit on their boards), along with the contractual requirement of PE funds to return their capital within seven to ten years, have resulted in capital structures that are far more leveraged than those of their publicly traded counterparts, but also considerably more provisional and “opportunistic.” Whereas the average U.S. public company has long operated with roughly 30% debt and 70% equity, today's typical private‐equity sponsored company is initially capitalized with an “upside‐down” structure of 70% debt and just 30% equity, and then often charged with working down its debt as quickly as possible. Although banks supplied most of the debt for the first wave of LBOs in the 1980s, the remarkable growth of the private equity industry in the past 25 years has been supported by the parallel development of a new leveraged acquisition finance market. This financing innovation has led to a general movement away from a bankcentered funding base to one comprising a relatively new set of institutional investors, including business development corporations and hedge funds. Such investors have shown a strong appetite for new debt instruments and risks that banks have been unwilling or, thanks to increased capital requirements and other regulatory burdens, prohibited from taking on. Notable among these new instruments are second‐lien loans and uni‐tranche debt—instruments that, by shifting the allocation of claims on the debtor's cash flow and assets in ways consistent with the preferences of these new investors, have had the effect of increasing the debt capacity of their portfolio companies. And such increases in debt capacity have in turn enabled private equity funds—now sitting on near‐record amounts of capital from their limited partners—to bid higher prices and compete more effectively in today's intensely competitive M&A market, in which high target acquisition purchase prices are being fueled by a strong stock market and increased competition from corporate acquirers.     

International Portfolio Investment Flows

This article develops a model of international equity portfolio investment flows based on differences in informational endowments between foreign and domestic investors. It is shown that when domestic investors possess a cumulative information advantage over foreign investors about their domestic market, investors tend to purchase foreign assets in periods when the return on foreign assets is high and to sell when the return is low. The implications of the model are tested using data on United States (U.S.) equity portfolio flows.     

Do different streams of capital flows affect asset prices differently?

This paper explores the impact of six types of gross capital flows (debt, equity, and banking gross inflows and outflows) on two dimensions: (1) extreme episodes of surges, stops, flights, and retrenchments, and (2) the probability of boom-busts in ASEAN-4 asset markets for the period 1993–2018. To this end, we first decompose gross capital inflows and outflows from Balance of Payments 5 and 6 and show that ASEAN-4 is largely dominated by portfolio flows and a relatively small magnitude of banking flows. However, when we link this decomposition to the extreme episodes, our findings show banking flows are volatile enough to cause greater occurrences of flight and retrenchment episodes while volatile debt flows tend to lead to surge and stop episodes. In the second part, we construct asset price index for ASEAN-4 that can detect boom-busts periods with a minimal noise-to-signal ratio eight quarters ahead. We use heteroscedasticity panel probit and ordinal generalized linear models to show that fundamental variables and banking inflows are statistically significant at increasing likelihood of boom-busts in asset markets. These two findings highlight that although largest percentage of capital flows come through debt and equity markets, the banking channel is of paramount importance in causing extreme episodes of flight and retrenchment as well as boom-busts of asset markets.     

Capital flows to emerging market economies: A brave new world?

We examine the determinants of net private capital inflows to emerging market economies (EMEs) since 2002. Our main findings are: First, growth and interest rate differentials between EMEs and advanced economies and global risk appetite are statistically and economically important determinants of net private capital inflows. Second, there have been significant changes in the behavior of net inflows from the period before the recent global financial crisis to the post-crisis period, especially for portfolio inflows, partly explained by the greater sensitivity of such flows to interest rate differentials since the crisis. Third, capital controls introduced in recent years do appear to have discouraged both total and portfolio net inflows. Finally, we find positive effects of unconventional U.S. monetary policy on EME inflows, especially portfolio inflows. Even so, U.S. unconventional policy is one among several important factors influencing flows.     

The cost of capital: U.S.-based multinational corporations versus U.S. domestic corporations

Using firm-level panel data, this paper examines whether the cost of capital (COC) differs significantly between U.S.-based multinational corporations (MNCs) and U.S. domestic corporations (DCs). The results suggest that U.S.-based MNCs have higher COC than U.S. DCs and that industry importantly influences COC. The study also finds that there is a significant time effect on COC, and the time effect follows the trend of the U.S. economic growth rate. Using a Bayesian Markov chain Monte Carlo approach, we estimate jointly cost of equity, cost of debt, and capital structure, and find that the higher cost of capital for MNCs is due mainly to their higher cost of equity and greater use of equity financing; the cost of debt financing does not differ significantly for MNCs versus DCs.     

Exploring the causal relationships and allocation puzzle between portfolio investments and real sector growth in Sub-Saharan Africa

This study explores the causal dynamics and allocation puzzles between real sector growth and portfolio investments (equity and private debt) in Sub Saharan (SSA). We use growth in manufacturing, industry, agriculture, and services to capture the real sector and employ the two-step dynamic systems GMM model to establish our empirical relationships over the period 1980–2017. We found no evidence in support of the puzzle at the overall level of the real sector and portfolio investments. However, at a decomposed level, we established a bi-directional relationship of a positive association between debt flows and growth in agriculture and services, with no evidence of an allocation puzzle. Though we found a bi-directional association between debt and industrial growth, the association was detrimental in both directions. Finally, the study established a two-way inverse causality between equity flows and manufacturing growth. The paper provides a strong foundation for an additional source of financing, especially for the growth of the service and agriculture sectors. The findings also indicate complementary reactions between real sector growth and portfolio investments in SSA.     

U.S. Equity Investment in Emerging Stock Markets

This article examines U.S. equity flows to emerging stock marketsfrom 1978 to 1991 and draws three main conclusions. First, despitethe recent increase in U.S. equity investment in emerging stockmarkets, the U.S. portfolio remains strongly biased toward domesticequities. Second, of the fraction of the U.S. portfolio thatis allocated to foreign equity investment, the share investedin emerging stock markets is roughly proportional to the shareof the emerging stock markets in the global market capitalizationvalue. Third, the volatility of U.S. transactions in emerging-marketequities is higher than in other foreign equities. The normalizedvolatility of U.S. transactions appears to be falling over time,however, and we find no relation between the volume of U.S.transactions in foreign equity and local turnover rates or volatilityof stock returns.     

International portfolio flows and exchange rate volatility in emerging Asian markets

This paper investigates the effects of equity and bond portfolio inflows on exchange rate volatility using monthly bilateral data for the US vis-a-vis seven Asian developing and emerging countries (India, Indonesia, Pakistan, the Philippines, South Korea, Taiwan and Thailand) over the period 1993:01–2015:11. GARCH models and Markov switching specifications with time-varying transition probabilities are estimated in addition to a benchmark linear model. The evidence suggests that high (low) exchange rate volatility is associated with equity (bond) inflows from the Asian countries toward the US in all cases, with the exception of the Philippines. Therefore, capital controls could be an effective tool to stabilise the foreign exchange market in countries where flows affect exchange rate volatility.     

Portfolio Capital Flows in Thailand: A Bayesian Model Averaging Approach

We study the gross and net terms of portfolio capital flows by examining their determinants. Through the application of the Bayesian model averaging method, the determinants are evaluated by a set of models instead of a single specification. Our findings show that the magnitude of both gross equity and gross debt flows are large, relative to their net terms. Equity inflows and outflows are quite symmetric with similar determinants; debt inflows and outflows are less symmetric. The paper provides partial evidence to support the importance of both internal and external factors as determinants of capital flows.
