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.
The issue of using monetary policy for financial stability purposes is hotly contested. The crisis was a reminder that price stability is not sufficient for financial stability, financial crises are costly, and policy should aim to decrease the likelihood of crises, not only rely on dealing with their repercussions once they occur. It is clear that well-targeted prudential policies (including micro and macroprudential regulation and supervision) should be pursued actively to attenuate the buildup of financial risks. The question is whether monetary policy should be altered to contain financial stability risks. Should it lend a hand by temporarily raising interest rates more than warranted by price and output stability objectives? Keeping rates persistently higher is also possible, but more costly.
22.3.1 Basic Characteristics
In the Mundell-Fleming framework, standard monetary policy and exchange rate flexibility fully insulate economies from shocks. However, that framework abstracts from many real world imperfections, and countries often resort to unconventional policies to cope with shocks, such as COVID-19. This paper develops a model of optimal monetary policy, capital controls, foreign exchange intervention, and macroprudential policy. It incorporates many shocks and allows countries to differ across the currency of trade invoicing, degree of currency mismatches, tightness of external and domestic borrowing constraints, and depth of foreign exchange markets. The analysis maps these shocks and country characteristics to optimal policies, and yields several principles. If an additional instrument becomes available, it should not necessarily be deployed because it may not be the right tool to address the imperfection at hand. The use of a new instrument can lead to more or less use of others as instruments interact in non-trivial ways.
Since at least the Great Financial Crisis, authorities around the world have increasingly relied on macroprudential policy to help secure financial stability and complement monetary policy as an integral element of a broader macro-financial stability framework. In today's interconnected global financial system, policy actions taken by the major advanced economies can have spillovers on the rest of the world through their impact on capital flows and exchange rates, potentially generating vulnerabilities across borders. Conversely, in emerging market economies, macroprudential policy as well as foreign exchange intervention and/or capital flow management policy can help mitigate the correspond...
We show that macroprudential regulation can considerably dampen the impact of global financial shocks on emerging markets. More specifically, a tighter level of regulation reduces the sensitivity of GDP growth to VIX movements and capital flow shocks. A broad set of macroprudential tools contribute to this result, including measures targeting bank capital and liquidity, foreign currency mismatches, and risky forms of credit. We also find that tighter macroprudential regulation allows monetary policy to respond more countercyclically to global financial shocks. This could be an important channel through which macroprudential regulation enhances macroeconomic stability. These findings on the benefits of macroprudential regulation are particularly notable since we do not find evidence that stricter capital controls provide similar gains.
The April 2019 Global Financial Stability Report (GFSR) finds that despite significant variability over the past two quarters, financial conditions remain accommodative. As a result, financial vulnerabilities have continued to build in the sovereign, corporate, and nonbank financial sectors in several systemically important countries, leading to elevated medium-term risks. The report attempts to provide a comprehensive assessment of these vulnerabilities while focusing specifically on corporate sector debt in advanced economies, the sovereign–financial sector nexus in the euro area, China’s financial imbalances, volatile portfolio flows to emerging markets, and downside risks to the hous...
The April 2018 Global Financial Stability Report (GFSR) finds that short-term risks to financial stability have increased somewhat since the previous GFSR. Medium-term risks are still elevated as financial vulnerabilities, which have built up during the years of accommodative policies, could mean a bumpy road ahead and put growth at risk. This GFSR also examines the short- and medium-term implications for downside risks to growth and financial stability of the riskiness of corporate credit allocation. It documents the cyclical nature of the riskiness of corporate credit allocation at the global and country levels and its sensitivity to financial conditions, lending standards, and policy and institutional settings. Another chapter analyzes whether and how house prices move in tandem across countries and major cities around the world—that is, global house price synchronicity.
In the wake of the 2008–09 global financial crisis, central banking and monetary policy in many corners of the world came under intense pressure and entered unchartered waters. The breadth and scale of central bank operations have been modified or expanded in unprecedented and even unimaginable ways given the circumstances. Additionally, a fundamental rethinking of central banking and its policy frameworks has been taking place. This volume reflects a multilateral effort to help close the gap in our knowledge in meeting the critical challenges presented by these significant changes, in particular, those confronting central banks in Latin America. The volume’s first section provides a panoramic overview of the policy progress made to date and the challenges that lie ahead. The related issue of spillovers and monetary independence is taken up more fully in the next section. The final section presents chapters that reexamine macroprudential and monetary policies and policy frameworks from the perspective of central bank staff members from the region.
