Securing Monetary and Financial Stability: Why Canada Needs a Macroprudential Policy Framework

A newly created Macroprudential Policy Framework with clear objectives, tools and lines of responsibility could offer greater assurance of financial stability, while leaving the to focus primarily on inflation and output stabilization.

Canada’s inflation-target agreement between the government and the Bank of Canada is up for renewal by 31 December 2016. In the aftermath of the 2008-2009 global financial crisis, one of the critical issues for consideration is the integration of price and financial stability in the conduct of policy. ThisCommentary addresses the importance for the conduct of monetary policy of having a separate coherent framework for macroprudential policy – designed to prevent the build-up of systemic, or system-wide, financial risks. A key lesson of the financial crisis was the insufficient attention being paid to these risks and their consequences for the economy. The importance of this issue can be seen in two ways. The first relates to the interactions between monetary and macroprudential policy tools in light of concerns about rising levels of household debt. At various times, there will be situations when only one policy tool is needed, when both policies need to be used in the same direction, or when the two policies need to work in opposite directions. The second relates to the Bank’s current “risk management approach” to monetary policy. In the absence of a government framework for the active use of macroprudential tools, this approach implies that monetary policy becomes a more important line of defence against systemic risks than it needs to be, with the risk of sub-optimal monetary policy outcomes. Our conclusions are threefold: • Canada’s 2 percent inflation target and policy framework has served the economy well, most importantly in anchoring inflation expectations; • over the past two years, Canadian monetary policy would have been better placed to combat low inflation and excess capacity had macroprudential policies been openly geared to reducing the systemic risks associated with rising household indebtedness and housing prices; and • drawing on best practices, the government needs to elevate macroprudential policies by establishing clear objectives, tools and lines of responsibility and accountability. The payoff for cannot be overstated: greater assurance of both financial stability, as a result of assigned responsibility for macroprudential policy, and monetary stability, as a result of the Bank of Canada’s continued primary focus on inflation and output stabilization.

The integration of financial stability considerations into the conduct of monetary policy has become an important issue in all countries. In Canada, how best to integrate price stability and financial stability is one of the central issues the Bank of Canada has identified in the lead-up to the 2016 renewal of the inflation-target agreement with the federal government (Côté 2014).

Inflation targeting was introduced in Canada in borrowers and financial institutions; (ii) regulatory 1991.

We address two aspects overall price stability. Since then, Canada has had of this issue that have immediate and practical an explicit inflation target that has been extended implications for Canadian monetary policy.

At the time of the 2011 renewal, the Bank of Depending on economic and financial Canada, as it did in 2006, recognized the need for conditions, there will be situations when only one flexibility in the conduct of monetary policy to policy tool is needed, when both policies need to play a role in support of financial stability. This be used in the same direction or when the two flexibility has been expressed in terms of the polices work in opposite directions. This means period over which the inflation target is achieved, policymakers need to understand not just the use of potentially involving a longer period to support each policy, but also what guides its use. Moreover, financial stability objectives. Nonetheless, monetary much of the impact of policies works through policy is seen as “the fourth line of defence” (Poloz expectations, which are heavily influenced by the 2014, 7) behind (i) the behaviour of individual guiding frameworks.

Any remaining errors remain the authors’ responsibility. 1 One of the distinguishing features of the renewal process has been the consistency in agreement to keep the target at an annual rate of increase in the CPI of 2 percent. Over the period from December 1995 to December 2014, annual CPI inflation averaged 1.9 percent. 3 Commentary 429

However, it typically should be supported by expansionary fiscal policy. Moreover, there is an argument to set macroprudential instruments looser than normal, especially if the need to operate at the effective lower bound is because of financial crisis. 6 This is often known as Tinbergen’s Law. 7 Commentary 429

The debate has centred on two approaches. One In contrast, there is almost nothing available on argues that monetary policy must play a more active a framework for macroprudential policy in Canada, and deliberate role in “leaning” against financial with the sole exception of the countercyclical capital booms such as excessive credit growth and ease buffer. As a result, it is difficult for the Bank of less aggressively during busts (Borio 2014).

No single body has the mandate for macroprudential oversight nor do any of the oversight committees have the membership that would allow for a comprehensive view of systemic risk across all financial institutions and markets in Canada” (IMF 2014, 25). 12 In practice, this means that the FPC can direct the use of these tools by the Prudential Regulatory Authority and Financial Conduct Authority. 11 Commentary 429
