Non-Technical SummaryThis paper offers an overview of the implications of the global financial cycle for conventional and unconventional monetary policies and macroprudential policy in small, open economies (SOEs) such as Canada. We start by reviewing the recent evidence on financial cycles. An important new finding is that national financial cycles may have been partly subsumed into a global financial cycle. The global financial cycle is driven, in part, by monetary policy decisions in the United States. Low-for-long U.S. policy rates cause global financial intermediaries to search for yield, which in turn leads to a decline in the cross-section of international risk premia. Risk premia form an important part of conventional and unconventional monetary policy transmission mechanisms in both large and small economies.Next, we review the available policy actions that could be undertaken by SOE central banks and regulatory authorities to limit the effects of the global financial cycle. We show that conventional monetary policy actions in both large and small economies are affected by movements in global risk premia. The paper also examines the effectiveness of unconventional monetary policies originating in SOEs that are not coordinated with those in large countries.If unconventional policies undertaken during financial crises are not completely effective in restoring output or inflation to their target levels, the question then arises as to whether central banks can use more aggressive conventional monetary actions to lean against the buildup of debt associated with the boom phase of the global financial cycle. We highlight new work that evaluates the potential for central banks to lean against the winds of the global financial cycle. This new work shows that the cost of leaning is quite high relative to the benefits of lowering the likelihood of either entering a house price correction episode or of triggering a new financial crisis.We then assess to what extent macroprudential policy tools could be an alternative to curb increased risk-taking behaviour during the boom phase of the cycle. In large economies, a number of macroprudential policies are designed to break the chain that links asset allocation decisions by financial intermediaries with the resultant declines in risk premia. Such policies are likely to be less effective in SOEs, as global premia will likely not change in the face of portfolio switches by s...
