Foreign Exchange Order Flows and the Thai Exchange Rate Dynamics

abstract

Applying the microstructure approach to exchange rates, this paper aims to shed light on the price formation process in the Thai foreign exchange market using a unique supervisory dataset of daily foreign exchange transactions from all licensed dealers in Thailand. We examine the main drivers of different types of order flows and the effect of resident and non-resident customer order flows on the Thai exchange rate. The results suggest that non-resident order flows have an important influence on movements in the Thai baht, while resident order flows do not. Regarding investors’ trading behavior, we find that non-resident order flows are driven by both fundamentals and movements of the Thai baht. Specifically, non-resident players appear to be ‘trend-followers’ with regard to exchange rate returns, exerting buying pressure when the baht recently appreciated. In contrast, domestic players tend to behave as ‘contrarians’, by buying the Thai baht after it depreciates.

Extrapolative Beliefs and Exchange Rate Markets

abstract

Following Engel (2016) and Valchev (2015), this paper documents the relationship between interest rate differentials and differential returns on domestic and foreign bonds over time horizon using a broader data sample. I find that countries with higher contemporaneous interest rates earn excess positive bond returns initially in accordance with previous UIP literature. However, the sign of excess returns reverses in the medium run. Higher contemporaneous interest rates predict negative excess returns. Eventually, interest differentials have no excess return predictability. I argue that behavioral bubbles are natural and successful candidates in generating exchange rate dynamics observed in the data. In particular, I propose that investors rely not only on fundamentals (interest differentials) but also extrapolate past exchange rates when forming expectations. The proposed extrapolative model is consistent with both excess return patterns and survey evidence in the data.

A Microscopic View of Thailand’s Foreign Exchange Market: Players, Activities, and Networks

abstract

This paper explores Thailand’s foreign exchange (FX) market landscape by utilizing the Bank of Thailand’s supervisory Financial Market Statistics (FMST) data which covers the universe of onshore foreign exchange transactions in Thailand. Historical developments regarding different groups of market players and the use of foreign exchange instruments, as well as the overall market structure are documented. Through the lens of network analysis, we also provide topological descriptions of Thailand’s FX market landscape, with applications on interbank network stability. We observe low degree of concentration among the dealer banks in terms of market turnover share. In contrast, from a customer’s perspective, market share is highly concentrated within a handful of large FX customers. The network connectivity among different groups of players suggests that the Thai FX market is one that is rather segmented and clustered among similar players. A substantial degree of specialization is evident across banks in terms of FX instruments and market segments, both in the interbank network and in the retail market. Probing into the interbank network stability, we find a small subset of banks to be truly central to the FX market network, though the system appears to hold up well in stress times supported by fluidity among interbank players.

Dynamic Connectedness in Emerging Asian Equity Markets

Pym Manopimoke, Suthawan Prukumpai and Yuthana Sethapramote

abstract

This paper examines dynamic connectedness among emerging Asian equity markets as well as explores their linkages vis-à-vis other major global markets. We find that international equity markets are tightly integrated. Measuring connectedness based on a generalized Vector Autoregressive model, more than half of all total forecast error variance in equity return and volatility shocks come from other markets as opposed to country own shocks. When examining the degree of connectedness over time, we find that international stock markets have become increasingly connected, with a gentle upward trend since the Asian financial crisis but with a rapid burst during the global financial crisis. Despite the growing importance of Asian emerging markets in the world economy, we find that their influence on advanced economies is still relatively small, with no significant increase over time. During the past decade, advanced markets have been consistently net transmitters of shocks while emerging Asian markets act as net receivers. Based on the nature of equity shock spillovers, we also find that advanced countries are still tightly connected amongst themselves while intraregional connectedness within Asia remains strong. By investigating whether uncertainty plays an important role in explaining the degree of stock market connectedness, we find that economic policy uncertainty from the US is an important source of financial shock spillover for the majority of international equity markets. In contrast, US financial market uncertainty as proxied by the VIX index drives equity market spillovers only among advanced economies.

The Impact of Imperfect Financial Integration and Trade on Macroeconomic Volatility and Welfare in Emerging Markets

abstract

This study examines how international integration impacts macroeconomic volatility and welfare in emerging market economies (EMEs), employing a two-country real business cycle model with constrained cross-border borrowing and imperfect access to international financial market. Parameter calibration employs 2000-2013 trade and external debt data from EMEs. The simulation shows that higher foreign debt raises output volatility, slightly reduces consumption volatility of entrepreneurs who can borrow abroad, and brings about welfare loss due to higher debt interest payments and less consumption. Households who can only save in domestic markets are largely unaffected. Restricted financial integration does not have much adverse impact when people face no other frictions domestically, suggesting the importance of domestic financial development. Higher international trade tends to be favorable for output variability, consumption smoothing, and welfare, but does not play a significant role on how cross-border borrowing affects macroeconomic volatility. The results suggest that the impacts of financial and trade integration are generally independent. It might be difficult for EMEs to achieve evident gains from greater financial integration even with high trade intensity when market imperfection exists. Increasing only trade or both types of integration together can be Pareto improving that lowers aggregate fluctuation, whereas increasing only private external debt is not.

Drivers of Financial Integration: Implications for Asia

Nasha Ananchotikul, Shi Piao and Edda Zoli

abstract

Deeper intraregional financial integration is prominent on Asian policymakers’ agenda. This paper takes stock of Asia’s progress toward that objective, analyzing recent trends in cross-border portfolio investment and bank claims. Then, it investigates the drivers of financial integration by estimating a gravity model of bilateral financial asset holdings on a large sample of source and destination countries worldwide, focusing in particular on the role of regulation and institutions. The paper concludes that financial integration in Asia could be enhanced through policies that lower informational frictions, continue to buttress trade integration and capital market development, remove restrictions to foreign flows and bank penetration, and promote a common regulatory framework.

Portfolio Flows, Global Risk Aversion and Asset Prices in Emerging Markets

Nasha Ananchotikul and Longmei Zhang

abstract

In recent years, portfolio flows to emerging markets (EMs) have become increasingly large and volatile. Using weekly portfolio fund flows data, the paper finds that their short-run dynamics are driven mostly by global “push” factors. To what extent do these cross-border flows and global risk aversion drive asset volatility in EMs? We use a Dynamic Conditional Correlation (DCC) Multivariate GARCH framework to estimate the impact of portfolio flows and the VIX index on three asset prices, namely equity returns, bond yields and exchange rates, in 17 emerging economies. The analysis shows that global risk aversion has a significant impact on the volatility of asset prices, while the magnitude of that impact correlates with country characteristics, including financial openness, the exchange rate regime, as well as macroeconomic fundamentals such as inflation and the current account balance. In line with earlier literature, portfolio flows to EMs are also found to affect the level of asset prices, as was the case in particular during the global financial crisis.

International Correlation Asymmetries: Frequent-but-Small and Infrequent-but-Large Equity Returns

Bruno Solnik and Thaisiri Watewai

abstract

We propose a novel regime-switching model to study correlation asymmetries in international equity markets. We decompose returns into frequent-but-small diffusion and infrequent-but-large jumps, and derive an estimation method for many countries. We find that correlations due to jumps, not diffusion, increase markedly in bad markets leading to correlation breaks during crises. Our model provides a better description of correlation asymmetries than GARCH, copula and stochastic volatilit ymodels. Good and bad regimes are persistent. Regime changes are detected rapidly and risk diversification allocations are improved. Asset allocation results in and out-of-sample are superior to other models including the 1/strategy.

Daily Movements in the Thai Yield Curve: Fundamental and Non-Fundamental Drivers

abstract

This paper attempts to identify the key determinants of daily yield movements in the Thai government bond market. It finds that Thai short-term yield movements are solely driven by domestic factors, namely policy rate expectations and bond supply. By contrast, longer-tenor yields are also found to be affected by global factors, namely global monetary conditions and global risk appetite. Apart from these “fundamental” factors, the net-buying pressures of foreign players, and not those of domestic investors, are also found to exert significant influence over the Thai medium and long rates. Taken alone, this finding may appear somewhat alarming as it implies that foreign activity can be a significant source of market volatility. Further investigations suggest, however, that the detected foreign influence may be due to informational reasons; foreign investors lead yield movements because they provide price-relevant “private” information to the market. Viewed in this light, the detected foreign influence may not altogether be so detrimental, at least insofar as normal periods are concerned.

Capital flows and the current account: Taking financing (more) seriously

Claudio Borio and Piti Disyatat

abstract

This paper questions the appropriateness of popular analytical frameworks that focus on current accounts or net capital flows as a basis for assessing the pattern of cross-border capital flows, the degree of financial integration and the vulnerability of countries to financial crises. In the process, it revisits the Lucas paradox, the Feldstein-Horioka puzzle and the notion of sudden stops. It argues that, in a world of huge and free capital flows, the centrality of current accounts in international finance, and hence in academic and policy debates, should be reconsidered.
