Dollar Safety and the Global Financial Cycle

Abstract We develop a model of the global financial cycle with one key ingredient: the international demand for safe dollar assets. The model matches patterns of dollar borrowing and currency mismatch, the U.S. external balance sheet, exorbitant privilege, spillovers of the U.S. monetary policy to the rest of the world, and the dollar as a global risk factor. In doing so, we lay out a novel transmission mechanism through which the U.S. monetary policy affects the currency market and the global economy. The global financial cycle is a dollar cycle.

External wealth of nations and systemic risk

External imbalances played a pivotal role leading to the global financial crisis and were an important cause of turmoil. While current account (flow) imbalances narrowed in the aftermath of the crisis, the net international investment position (NIIP) (stock) imbalances persisted. This study explores the implications of countries’ net foreign positions on systemic risk. Using a sample of 470 banks located in 49 advanced economies, emerging countries, and developing economies over 2000–2020, we find robust empirical evidence that banks can reduce their systemic risk exposure when the countries in which they are incorporated improve their NIIPs and maintain creditor status vis-à-vis the rest of the world. However, only the equity component of the NIIP is responsible for this outcome, whereas debt flows are not significant. Similarly, we find that the mitigating effect of an external balance sheet on systemic risk is derived from valuation gains rather than from the incremental net acquisition of assets or liabilities represented by the current account. Our findings are particularly relevant for policymakers seeking to improve banks’ resilience to adverse shocks and maintain financial stability.

The Shock Absorbing Role of Cross-border Investments: Net Positions Versus Currency Composition

We present a comprehensive analysis of the shock absorption role of external positions using the currency exposures dataset by Bénétrix et al. (2020). While the literature has frequently studied how the net international investment position and its currency composition determine the direction and scale of valuation effects, we focus on their amplitude. This is of central importance for global financial stability given the large and increasing scale of external balance sheets. To that end, we propose an indicator showing the extent to which external positions absorb or amplify exchange rate shocks. Analysing a set of 50 countries over the period 1990-2017, we find the external shock absorption role to be present for advanced economies, while this was initially not the case for emerging markets economies (EMEs). In recent years, however, EMEs’ external positions increasingly showed a shock absorption capacity. Our regression-based analysis reveals that the level of economic and financial development is associated with a greater capacity to absorb exchange rate shocks.

International Macroeconomics: From the Great Financial Crisis to COVID-19, and Beyond

This Mundell–Fleming lecture reviews some of the main developments in international macroeconomics since the early 2000s. It highlights four important areas of progress: (a) on international pricing and invoicing; (b) on sectoral trade and production networks; (c) on the cross-border allocation of capital and the role of global financial intermediaries; (d) on cross-border externalities and prudential policies. It then explores three specific questions, relevant for future research and policy: (a) the implementation of optimal prudential policy via ‘basis control;’ (b) recent developments about the US external balance sheet and its ‘exorbitant privilege;’ and (c) the reform of the International Financial and Monetary System.

External Balance Sheets and the COVID-19 Crisis

At the onset of the COVID-19 economic crisis, as in other crisis episodes, we observed a rapid appreciation of “safe haven” currencies. We quantify currency-induced balance sheet valuation effects for aggregate external positions as well as for broadly defined asset classes for the first quarter and the full year 2020. To do so, we use new data on the currency composition of cross-border assets and liabilities for 46 countries. In contrast with past financial crises, many emerging markets did not experience losses on their aggregate external balance sheets despite facing a domestic currency depreciation. This was partly due to currency-induced valuation gains on equity positions offsetting losses on debt positions, and partly due to reduced currency mismatch on their external debt positions. We conduct the stock-flow reconciliation of net international investment positions to measure overall valuation effects and compute the proportion that is due to changes in currency values. For about half of the countries in our sample, currency-induced valuation effects were substantial, representing over 50 percent of total valuation effects in 2020Q1 and the full year 2020.

External balance sheets of emerging economies: low-yielding assets, high-yielding liabilities

The new millennium has witnessed a rapid expansion of external balance sheets and significant changes in the capital, currency and sectoral compositions of foreign assets and liabilities of emerging economies. These have created new channels of transmission of global financial shocks and amplified the susceptibility of the value of their outstanding stocks of gross foreign assets and liabilities to global financial conditions, leading to sizeable wealth transfers between emerging and advanced economies. They have also resulted in significant income transfers in view of negative yield differentials between their gross external assets and liabilities. Altogether, such transfers to advanced economies are estimated to have reached 2.3 per cent of the combined GDP of the G20 emerging economies per annum during 2000–2016.

Foreign-currency exposures and the financial channel of exchange rates: Eroding monetary policy autonomy in small open economies?

Foreign-currency exposures on an economy’s external balance sheet may jeopardise financial stability when the exchange rate depreciates. In fact, theory suggests that in such an environment it may be optimal for monetary policy in a floating regime to reduce exchange rate variation by mimicking foreign monetary policy in order to dampen financial cycles rather than focusing exclusively on stabilising the business cycle. We explore whether there is evidence in the data for monetary policy in small open economies facing such a trade-off between financial stability and macroeconomic stabilisation that gives rise to “fear-of-floating”. In a panel data set for 26 advanced and emerging small open economies with floating regimes for the time period from 2000 to 2017 we document evidence that is consistent with fear-of-floating, i.e. that small open economy monetary policy responds to base-country monetary policy even after controlling for macroeconomic fundamentals. We find that this fear-of-floating is particularly pronounced in the presence of foreign-currency exposures. Specifically, fear-of-floating is stronger when the foreign-currency exposures arise through debt rather than non-debt instruments, which is consistent with existing evidence documenting that these instruments are more fickle and sensitive to swings in investor sentiment. Moreover, the evidence for fear-of-floating is stronger when base-country monetary policy is tightened, suggesting that fear-of-floating typically arises in the face of immediate threats to financial stability due to depreciation pressures in the presence of foreign-currency exposures, rather than as preemptive action to mitigate the build-up of such vulnerabilities when the currency is appreciating.

The International Monetary and Financial System

International currencies fulfill different roles in the world economy, with important synergies across those roles. We explore the implications of currency hegemony for the external balance sheet of the United States, the process of international adjustment, and the predictability of the US dollar exchange rate. We emphasize the importance of international monetary spillovers and of the exorbitant privilege, and we analyze the emergence of a new Triffin dilemma.

Monetary Policy Spillovers, Capital Controls and Exchange Rate Flexibility, and the Financial Channel of Exchange Rates

We assess the empirical validity of the trilemma (or impossible trinity) in the 2000s for a large sample of advanced and emerging market economies. To do so, we estimate Taylor-rule type monetary policy reaction functions, relating the local policy rate to real-time forecasts of domestic fundamentals, global variables, as well as the base-country policy rate. In the regressions, we explore variations in the sensitivity of local to base-country policy rates across different degrees of exchange rate flexibility and capital controls. We find that the data are in general consistent with the predictions from the trilemma: Both exchange rate flexibility and capital controls reduce the sensitivity of local to base-country pol- icy rates. However, we also find evidence that is consistent with the notion that the financial channel of exchange rates highlighted in recent work reduces the extent to which local policymakers decide to exploit the monetary autonomy in principle granted by flexible exchange rates in specific circumstances: The sensi- tivity of local to base-country policy rates for an economy with a flexible exchange rate is stronger when it exhibits negative foreign-currency exposures which stem from portfolio debt and bank liabilities on its external balance sheet and when base-country monetary policy is tightened. The intuition underlying this finding is that it may be optimal for local monetary policy to mimic the tightening of base-country monetary policy and thereby mute exchange rate variation because a depreciation of the local currency would raise the cost of servicing and rolling over foreign-currency debt and bank loans, possibly up to a point at which finan- cial stability is put at risk.

Reducing large net foreign liabilities

AbstractIn light of persistently large net foreign liability (NFL) positions in several euro area countries, we analyze 138 episodes of sizeable NFL reductions for a broad sample of advanced and emerging economies. We provide stylized facts on the channels through which NFLs were reduced and estimate factors that make episodes “stable”, that is, sustained over the medium term. Our findings show that while GDP growth and valuation effects contribute most to NFL reductions overall, stable reduction episodes also require positive transaction effects (i.e., current account surpluses), in particular in advanced economies. Considering the different components of a country's external balance sheet, we observe that reduction episodes were almost exclusively driven by a decline in gross external liabilities in emerging economies, while in advanced economies also gross external asset accumulation contributed significantly, in particular in stable episodes. Our econometric analysis shows that NFL reductions are more likely to be sustained if a country records strong average real GDP growth during an episode and exits the episode with a larger current account surplus that consists of a combination of relatively high exports, low imports and low net factor income payments. Moreover, we find evidence that nominal effective exchange rate depreciation during an episode is helpful for achieving episode stability in the short run, while IMF programs and sovereign debt restructurings also contribute to longer term stability.

Finance, power, and the British balance of payments

ABSTRACTThe Brexit referendum marks a critical juncture in Britain’s political economy. Benjamin Cohen argues that a nation’s monetary sovereignty lies in its balance of payments (BoP) flexibility (2008, 2015). I argue that a country’s position in the global financial régime must also be accounted for when explaining its BoP dynamics. This allows us to understand why, while sterling has long lost its ‘world currency’ status, Britain’s BoP exhibits some of the same features associated with American ‘exorbitant privilege’. To appreciate the UK’s own BoP flexibilities as well as to flesh out the Anglo-American axis in the international financial order, I compare the UK’s external balance sheets with those of the US. Given the complexities and uncertainties inherent in BoP analyses, I advise against micro-analyses of the BoP in favour of a broader approach that takes into account macro-dynamics as well as the International Political Economy (IPE) concerns outlined above. Elaborating such an analysis for the UK BoP, I explore the potential implications of Brexit for Britain’s external balance sheets and its political-economic future. While Britain’s financial power has helped insulate its balance sheets from external shocks, Britain’s impending departure from the European Union heralds a period of considerable uncertainty.

External Sector Report, July 2018

The External Sector Report presents a methodologically consistent assessment of the exchange rates, current accounts, reserves, capital flows, and external balance sheets of the world’s largest economies. The 2018 edition includes an analytical assessment of how trade costs and related policy barriers drive excess global imbalances.

External Balance Sheets as Countercyclical Crisis Buffers

The external balance sheets of many emerging market countries are distinguished by their holdings of assets primarily in the form of foreign debt and foreign exchange reserves, while their liabilities are predominantly equity, either foreign direct investment or portfolio equity. We investigate the claim that this composition served as a buffer for the emerging markets during the global financial crisis of 2008-09. We use data from a sample of 67 emerging market and advanced economies, and several indicators of the crisis are utilized: GDP growth rates in 2008-09, the occurrence of bank crises and the use of IMF credit. Our results show that those countries that issued FDI liabilities had higher growth rates, fewer bank crises and were less likely to borrow from the IMF. Countries with debt liabilities, on the other hand, had more bank crises and were more likely to use IMF credit. We conclude that the “long debt, short equity” (hold debt assets, issue equity liabilities) strategy of emerging markets did mitigate the effects of the global financial crisis.

Leading Indicators and Financial Crisis: A Multi-Sectoral Approach Using Signal Extraction

Using signal extraction, this study identifies leading indicators of financial crisis over the period 1980-2015 in developing and advanced economies. The study evaluates vulnerability in the external, public and financial sector in developing countries. The results postulate that the level of imports is the principal leading indicator for detecting a forthcoming crisis in developing nation’s external sector. In the public sector, the best indicators for predicting a crisis in South Africa are in the order: maturity of debt; external debt; debt-GDP ratio; interest rate payments; short-term debt and government expenditure. In Namibia, the best indicator for predicting crisis is total expenditure and interest rate payments. Comparatively, Russia’s crises are better predicted by the following variables: debt ratio; interest rate payments; short-term debt; expenditure and external debt. The two best indicators were debt ratio and interest rate payments. In the financial sector, the common risk indicator among developing economies is the lending rate. The external balance sheet assessment shows that in developed countries, predictors of a financial emanate from portfolio investments and direct investments. For the UK, the best indicators of a looming financial crisis are: direct investment liabilities; portfolio debt liabilities and direct investment debt instruments.

Partners, not debtors: The external liabilities of emerging market economies

This paper investigates the change in the composition of the liabilities of emerging market countries from primarily debt (bonds, bank loans) to equity (foreign direct investment, portfolio) in the decades preceding the global financial crisis. We examine the determinants of equity and debt liabilities on external balance sheets in a sample of 21 emerging market economies and 20 advanced economies over the period of 1981–2013. We include a new measure of domestic financial development that allows us to distinguish between financial institutions and financial markets. Our results show that countries with higher economic growth rates have larger amounts of equity liabilities. The development of domestic financial markets is also linked to an increase in equity liabilities, and in particular, portfolio equity. In addition, larger foreign exchange reserves are associated with larger amounts of portfolio equity. FDI liabilities are more common when domestic financial institutions are not well developed

Financial globalisation and monetary policy effectiveness

In theory financial globalisation has an ambiguous effect on monetary policy effectiveness. On the one hand, exposure to global financial cycles dampens the output effect of a tightening in monetary policy in financially integrated economies and thereby reduces monetary policy effectiveness. On the other hand, another salient feature of financial globalisation is that economies have become increasingly net long in foreign currency, which amplifies monetary policy effectiveness: economies experience larger valuation losses and wealth effects on their external balance sheets in response to an exchange rate appreciation when monetary policy is tightened, hence triggering stronger output effects. We quantify empirically the net impact of financial globalisation on monetary policy effectiveness through these two opposing channels. We find that since the 1990s the second channel has dominated so that financial globalisation has amplified monetary policy effectiveness in the typical advanced and emerging market economy. By our estimates, the output effect of a tightening in monetary policy has increased by 25% due to financial globalisation. Our results imply that financial globalisation has modified the transmission of monetary policy by strengthening the importance of the exchange rate channel.

Atlas constrained: the US external balance sheet and international monetary power

ABSTRACTWe address the impact on international monetary power of the size and nature of the US's international financial assets and liabilities. Financial globalization makes critical a focus on a nation's international financial assets and liabilities, its ‘external balance sheet’. We suggest an expansion of Cohen's existing framework of international monetary power to include the implications of valuation changes in these external balance sheets, focusing on sources of valuation, sensitivity and vulnerability of the US economy to these changes and implications for US ability to use monetary statecraft. By focusing on developments since 2007 and on events over the financial crisis period, we show that the increased size and nature of the US's external balance sheet has reduced US autonomy and monetary power. Underpinning the changes in the US's external balance sheet are activities of private financial market actors whose influence in international monetary affairs has grown markedly.
