There are many reasons cited for this week’s market turndown and risk pullback, including concerns about global growth, Ebola, turmoil in the Middle East, and excessive investor comfort from easy money. What has been less commented on is the role played by last weekend’s IMF and World Bank Annual Meetings. Sometimes these meetings pass uneventfully, but sometimes bringing so many people together—policymakers and market people—creates a conversation that moves the consensus and as a result moves markets. It seems this year’s was one of those occasions. As the meetings progressed, optimism about a G-20 growth agenda and infrastructure boom receded and concerns about growth outside of the United States began to dominate the discussion. The perception that policymakers—particularly European policymakers—were either unable or unwilling to act contributed to the gloom. Time will tell whether macro risk factors that markets have shrugged off over the past few years will now be a source of volatility going forward. But if that is the case, perhaps these meetings had something to do with it.
