Portfolio Inflows and Real Effective Exchange Rates: Does the Sectorization Matter?
Description: It has been well-established in the literature that portfolio inflows appreciate the real effective exchange rate. However, the literature lacks a systematic empirical analysis of the impact of portfolio inflows by institutional sector or borrower type. This paper fills this gap by exploring the impact of the inflows of portfolio capital into three institutional sectors (government, banks and corporates) on the real effective exchange rate. Using a large sample of 73 countries, it shows that the effect of portfolio inflows on the real effective exchange rate depends on the sector the investment flows in. The findings are robust to different econometric methods, additional variables in the model, and various indicators of real effective exchange rates.

Riding the Energy Transition: Oil Beyond 2040
Description: Recent technological developments and past technology transitions suggest that the world could be on the verge of a profound shift in transportation technology. The return of the electric car and its adoption, like that of the motor vehicle in place of horses in early 20th century, could cut oil consumption substantially in the coming decades. Our analysis suggests that oil as the main fuel for transportation could have a much shorter life span left than commonly assumed. In the fast adoption scenario, oil prices could converge to the level of coal prices, about $15 per barrel in 2015 prices by the early 2040s. In this possible future, oil could become the new coal.

Bank Solvency and Funding Cost: New Data and New Results
Description: This paper presents new evidence on the empirical relationship between bank solvency and funding costs. Building on a newly constructed dataset drawing on supervisory data for 54 large banks from six advanced countries over 2004–2013, we use a simultaneous equation approach to estimate the contemporaneous interaction between solvency and liquidity. Our results show that liquidity and solvency interactions can be more material than suggested by the existing empirical literature. A 100 bps increase in regulatory capital ratios is associated with a decrease of bank funding costs of about 105 bps. A 100 bps increase in funding costs reduces regulatory capital buffers by 32 bps. We also find evidence of non-linear effects between solvency and funding costs. Understanding the impact of solvency on funding costs is particularly relevant for stress testing. Our analysis suggests that neglecting the dynamic features of the solvency-liquidity nexus in the 2014 EU-wide stress test could have led to a significant underestimation of the impact of stress on bank capital ratios.

International Financial Integration in the Aftermath of the Global Financial Crisis
Description: This paper documents the evolution of international financial integration since the global financial crisis using an updated dataset on external assets and liabilities, covering over 210 economies for the period 1970-2015. It finds that the growth in cross-border positions in relation to world GDP has come to a halt. This reflects much weaker capital flows to and from advanced economies, with diminished cross-border banking activity, and an increase in the weight of emerging economies in global GDP, as these economies have lower external assets and liabilities than advanced economies. Cross-border FDI positions have continued to expand, unlike positions in portfolio instruments and other investment. This expansion reflects primarily positions vis-à-vis financial centers, suggesting that the complexity of the corporate structure of large multinational corporations is playing an important role. The paper also explores the cross-country drivers of foreign ownership of domestic debt securities, highlighting in particular the role of the euro debt crisis in explaining its evolution.

Debt Sustainability in Low-Income Countries: Policies, Institutions, or Shocks?
Description: This paper estimates the determinants of external debt distress in low-income countries (LICs), disentangling the roles of institutions, shocks, and policies. The most prominent factors in raising the risk of debt distress are the weak protection of private property rights, adverse shocks to real non-oil commodity prices, and a high debt burden. Results also suggest that weak economic institutions tend to raise the probability of debt distress through persistently weak economic policies and high vulnerability to external shocks. The model enables a more granular analysis of debt sustainability in LICs and has a higher predictive power compared to the earlier scant literature.

Collateral Reuse and Balance Sheet Space
Description: Transactions on wholesale capital markets are often secured by marketable collateral. However, collateral needs balance sheet space to move within the financial system. Certain new regulations that constrain private sector bank balance sheets may have the effect of impeding collateral flows. This may have important consequences for monetary policy transmission, for short term money market functioning, and for market liquidity. In this context (and in contrast to the literature, which has focused mainly on the repo market), this paper analyzes securities-lending, derivatives, and prime-brokerage markets as suppliers of collateral. It highlights the incentives created by new regulations for different suppliers of collateral. Moreover, it argues that the central banks should be mindful of the effect of their actions on the ability of markets to intermediate collateral.

Bank Balance Sheets and the Value of Lending
Description: We study 1,400 UK syndicated loans, together with the financial history of the lead bank and the borrowing firm. We interpret abnormal equity returns around loan announcements as the value of the lending relationship to the firm. We find that: (i) Consistent with previous evidence, the value of lending is higher when the firm is riskier or more opaque, suggesting that it primarily reflects the lead bank’s screening and monitoring activities. (ii) As a bank becomes larger, more profitable or more capitalized, the value of its loans first increases and then decreases. The largest, most capitalised or most profitable banks do not give the most valuable loans. (iii) Firms which receive low-value loans are more likely to experience low profitability and financial distress during the lending relationship. By relating the state of bank balance sheets to borrower performance, we offer a new angle to evaluate the impact of financial conditions on the real economy.

Can They Do It All? Fiscal Space in Low-Income Countries
Description: According to U.N. estimates, low-income countries will have to increase their annual public spending by up to 30 percent of GDP to achieve the Sustainable Development Goals (SDGs), raising the question of whether they can do it all. This paper develops a new metric of fiscal space in low-income countries that accounts for macroeconomic uncertainty, allowing us to assess whether those spending needs can be accommodated. Illustrative simulations based on this methodology imply that, even under benign conditions, the fiscal space available in lowincome countries is likely insufficient to undertake the spending needed to achieve the SDGs. Improving public investment efficiency and domestic revenue mobilization can somewhat narrow the gap but it will require major efforts relative to recent trends.

Evaluating the Impact of Non-Financial IMF Programs Using the Synthetic Control Method
Description: We use the Synthetic Control Method to study the effect of IMF advice on economic growth, inflation, and investment. The analysis exploits the existence of IMF programs that do not involve any financing (Policy Support Instruments, “PSIs”). This enables us to focus on the effects of IMF monitoring, advice, and approval (as opposed to direct financial assistance). In addition, countries with non-financial programs are typically not crisis-struck – thereby mitigating the reverse causality problem and facilitating the construction of counterfactuals. Results suggest that treated countries add about 1 percentage point in annual real GDP per capita growth, with inflation being lower by some 3 percentage points per year. While we do not find evidence for an impact on total investment and the resulting capital stock, PSI-treatment does seem to stimulate foreign direct investment.

Lasso Regressions and Forecasting Models in Applied Stress Testing
Description: Model selection and forecasting in stress tests can be facilitated using machine learning techniques. These techniques have proved robust in other fields for dealing with the curse of dimensionality, a situation often encountered in applied stress testing. Lasso regressions, in particular, are well suited for building forecasting models when the number of potential covariates is large, and the number of observations is small or roughly equal to the number of covariates. This paper presents a conceptual overview of lasso regressions, explains how they fit in applied stress tests, describes its advantages over other model selection methods, and illustrates their application by constructing forecasting models of sectoral probabilities of default in an advanced emerging market economy.
