Essays in the US dollar dominated international financial market
Abstract/Contents
- Abstract
- This dissertation studies a special feature about the international financial market. Classical theories often assume that countries are symmetric, but realistically the international financial market is heavily US dollar dominated, which stimulates my interest to study whether this role of the US dollar can resolve numerous puzzles that classical theories are unable to reconcile with empirical facts, as well as to study policy implications. The role of the US in the international market is mainly unique in two aspects. First, the US dollar is the dominant currency used in international trade. Second, the US treasuries are considered as the most widely accepted safe assets. In this dissertation, the first two chapters study the safe asset role, and the third chapter explores the invoicing currency role. The first chapters analyzes the phenomenon called the US 'Exorbitant Privilege', which describes the fact that the US is the only large net borrower country in the world earning a positive net investment income. To rationalize this phenomenon, I propose a different theory about the role of US in the international financial system being a service provider, in contrast to the conventional view of an insurance provider, which predicts the US exorbitant privilege would vanish during the financial crisis, not supported by data. I build a two-country model with financial friction to explain the dynamics of the US external balance sheet and the dollar exchange rate. In the model, world financial intermediaries demand US safe assets for their convenience value, but US intermediaries do not demand foreign safe assets. Under an aggregate symmetric financial shock, the rest of the world buys more safe assets from the US despite a rise in convenience yield, the dollar appreciates, and the US takes advantage by buying more equities from the rest of the world at a low price. I show my mechanism can quantitatively explain the data, while a real shock triggering risk-sharing dynamic cannot. The second chapter is a paper completed with coauthors Shanaka J. Peiris and Sanaa Nadeem from the IMF. We take a perspective from Asian small open economies against external shocks driven by the US dollar. We focus on the banking sectors in those economics because in emerging Asia banks constitute the dominant source of financing consumption and investment, and bank balance sheets comprise large gross FX assets and liabilities. This paper extends the DSGE model of Gertler and Karadi (2011) to incorporate these key features and estimates a panel vector autoregression on ten Asian economies to understand the role of the banking sector in transmitting spillovers from the global financial cycle to small open economies. It also evaluates the effectiveness of foreign exchange intervention (FXI) and other macroeconomic policies in responding to external financing shocks. External financial shocks affect net external liabilities of banks and the exchange rate, leading to changes in credit supply by banks and investment. For example, a capital outflow shock leads to a deprecation that reduces the net worth and intermediation capacity of banks exposed to foreign currency liabilities. In such cases, the exchange rate acts as shock amplifier and sterilized FXI, often deployed by Asian economies, can help cushion the economy. By contrast, with real shocks, the exchange rate serves as a shock absorber, and any FXI that weakens that function can be costly. We also explore the effectiveness of the monetary policy interest rate, macroprudential policies (MPMs) and capital flow management measures (CFMs). The third chapter written with coauthors Zhengyang Jiang and Timothy Mok, exhibits a channel of how US monetary policy can have an asymmetric spillover effects and hence how the US can take advantage. We develop a model of two countries, U.S. and Japan. Households in both countries need to hold cash in advance to purchase consumption goods: The U.S. dollar can be used to purchase both countries' goods, while the Japanese yen can only be used to purchase Japan's goods. Under these constraints, an expansionary U.S. monetary policy leads to (1) a larger U.S. trade deficit, (2) larger foreign holdings of the U.S. dollar, and (3) an appreciation of the U.S. real exchange rate. In contrast, the Japanese monetary policy has none of these real effects. Beyond asymmetric monetary effects, our novel mechanism also explains the correlation between consumption and real exchange rate, and the connection between foreign economic growth and the demand for the U.S. dollar.
