We study interactions between monetary and macroprudential policies in a model with nominal and financial frictions. The latter derive from a financial sector that provides credit and liquidity services that lead to a financial accelerator-cum-fire-sales amplification mechanism. In response to fluctuations in world interest rates, inflation targeting dominates standard Taylor rules, but leads to increased volatility in credit and asset prices. The use of a countercyclical macroprudential instrument in addition to the policy rate improves welfare and has important implications for the conduct of monetary policy. “Leaning against the wind” or augmenting a standard Taylor rule with an argument on credit growth may not be an effective policy response.

We explore optimal monetary and macroprudential policy rules for a small open economy. Delegating 'lean against the wind' squarely to macroprudential policy provides a more robust policy mix to shock uncertainty—(i) if macroprudential measures exist, there are no significant welfare gains from monetary policy reacting to credit growth under a financial shock; and (ii) monetary responses to financial markets could generate bigger welfare losses than macroprudential responses under different shocks. The source of outstanding liabilities also plays a role in the choice of policy instrument— macroprudential policies are particularly effective for emerging markets where foreign borrowing is sizeable.

This paper develops an open-economy DSGE model with an optimizing banking sector to assess the role of capital flows, macro-financial linkages, and macroprudential policies in emerging Asia. The key result is that macro-prudential measures can usefully complement monetary policy. Countercyclical macroprudential polices can help reduce macroeconomic volatility and enhance welfare. The results also demonstrate the importance of capital flows and financial stability for business cycle fluctuations as well as the role of supply side financial accelerator effects in the amplification and propagation of shocks.

The recent crisis showed that price stability does not guarantee macroeconomic stability. In several countries, dangerous financial imbalances developed under low inflation and small output gaps. To ensure macroeconomic stability, policy has to include financial stability as an additional objective. But a new objective demands new tools: macroprudential tools that can target specific sources of financial imbalances (something monetary policy is not well suited to do). Effective macroprudential policies (which include a range of constraints on leverage and the composition of balance sheets) could then contain risks ex ante and help build buffers to absorb shocks ex post.

The book discusses contemporary issues such as global financial architecture and regulatory practices, trade, investment and the multilateral process, the future of work, the role of technology for adaptation and mitigation of climate change, and financing infrastructure for sustainable development. With increasing global connectivity, events in one part of the world immediately affect or spread to the other parts. In this context, G20 has proved to be an effective forum, particularly after the Asian financial crises. Furthermore, over recent decades, G20 has been instrumental in managing financial crises and international conflicts by deploying global cooperation as a functional tool. As a body responding to crises, the G20 has played a central role in providing the political momentum for the strong international cooperation that ensured greater policy coherence and helped ease situations that could otherwise have been decidedly worse. The G20’s agendas have encompassed short-term but critical issues of economic recovery, the sovereign crisis of Europe, high unemployment and financial sector regulation. But since moderate stabilization in the global economic environment, the focus of the group has also embraced long-term areas of governance and development. For emerging economies, such as India, the G20 has been an important platform framework to promote an inclusive global economic architecture that seeks to achieve equitable outcomes. This book reviews the past 20 years of the G20, since it was conceptualized as a replacement for the G-7. While issues such as global financial order have been a constant area of discussion, one of the failures has been not recognizing and acknowledging the importance of issues like trade, climate change and future of work. Featuring academic papers by experts in the area, this book provides a platform for the necessary discourse on these issues.

Recurrent crises in emerging markets and in advanced economies in the last decades cast doubt about the ability of financial liberalization to meet the aims of sustainable economic growth and development. The increasing importance of financial markets and financial efficiency criterion over economic decisions and policies since the 1980s laid down the conditions of the development process of emerging market economies. Numerous crises experienced thereafter gave rise to flourishing work on the links between financialization and economic development. Several decades of observations and lessons can now be integrated into economic and econometric models to give more sophisticated and multivariable approaches to financial development with respect to growth and development issues. In the markets-based and private-enterprise dominated world economy, two conditions for a successful growth-enhancing financial evolution can at least be brought fore: macroeconomic stability and consistent supervision. But even after the 2007-2008 global crisis, economists do not agree on the meaning of those conditions. For liberal and equilibrium-market economists, good finance and supervision mean market-friendly structures while for institutionalists, post-Keynesian and Marxist economists, good finance and supervision must lie in collectively designed and managed public structures. Drawing heavily on the tumultuous crises of the 1990s-2000s, this book argues that those experiences can shed light on such a crucial issue and lead economic theory and policy to go beyond the blindness of efficient free markets doctrine to economic catastrophes. It also points to new challenges to global stability in the wake of reconfiguration of international financial arena under the weight of major emerging market economies.

Central Bank Policy: Theory and Practice analyses various policies, theories and practices adopted by central banks, as well as the institutional arrangements underlying the principles of good governance in policy-making. It is the first book to comprehensively discuss the latest theories and practices of central bank policy.

Capital flows can deliver substantial benefits for countries, but also have the potential to contribute to a buildup of systemic financial risk. Benefits, such as enhanced investment and consumption smoothing, tend to be greater for countries whose financial and institutional development enables them to intermediate capital flows safely. Post-crisis reforms, including the development of macroprudential policies (MPPs), are helping to strengthen the resilience of financial systems including to shocks from capital flows. The Basel III process has improved the quality and level of capital, reduced leverage, and increased liquid asset holdings in financial systems. Drawing on and complementing such international reforms at the national level, robust macroprudential policy frameworks focused on mitigating systemic risk can improve the capacity of a financial system to safely intermediate cross-border flows. Macroprudential frameworks can play an important role over the capital flow cycle, and help members harness the benefits of capital flows. Introducing macroprudential measures (MPMs) preemptively can increase the resilience of the financial system to aggregate shocks, including those arising from capital inflows, and can contain the build-up of systemic vulnerabilities over time, even when such measures are not designed to limit capital flows. While the risks from capital outflows should be handled primarily by macroeconomic policies, a relaxation of MPMs may assist, as long as buffers are in place, in countering financial stresses from outflows. Capital flow liberalization should be supported by broad efforts to strengthen prudential regulation and supervision, including macroprudential policy frameworks. The Fund has two frameworks to help ensure that its advice on MPPs and policies related to capital flows is consistent and tailored to country circumstances. The frameworks (the Macroprudential framework and the Institutional View on capital flows) are consistent in terms of key principles, including avoiding using MPMs and capital flow management measures (CFMs) as a substitute for necessary macroeconomic adjustment. The appropriate classification of measures is important to ensure targeted advice consistent with the two frameworks. The conceptual framework for the assessment of measures laid out in this paper will assist staff in properly identifying MPMs and measures that are designed to limit capital flows and to reduce systemic financial risk stemming from such flows (CFM/MPMs), and thereby ensure the appropriate application of the Fund’s frameworks, so that staff policy advice is consistent and well targeted. The Fund will continue to develop and share expertise in using MPMs, and integrate these findings into its surveillance and technical assistance, which should contribute to building international understanding and experience on these issues.

This is an open access book. This book is an integration of keynote speeches, lectures, and related teaching materials during the five years of the "Central Bank Policy Mix: Issues, Challenges and Policy Responses" flagship program of the BI Institute, the learning and research centre of Bank Indonesia. The book examines the interactions among central bank policies including monetary policy, exchange rate policy, macroprudential policy, and capital flow management and also elaborates on modeling issues and quantitative analysis of the interaction between macroeconomic variables and policy instruments.
