The Contagion of Fear

Fears of a possible coronavirus pandemic are sweeping the world. Markets are jittery with little hard data to go on.
With the first case now reported in Canada, many are recalling the 2003 SARS where Canada was one of the epicenters. Arguably the biggest (economic) lesson from that experience is that fear is the biggest risk to the outlook.
The impact of the SARS pandemic on the Canadian economy is difficult to estimate, confounded as it was by the slowing US economy, the invasion of Iraq and other events, but the Bank of Canada estimated -0.6ppt hit to annualized growth in Q2-2003, or just over 0.1% on the level of GDP.
While it is premature to predict the path of today’s coronavirus outbreak, we estimate that a SARS-equivalent pandemic today could have a similar impact on the Canadian economy with an estimated hit of just over 0.1% on the level of GDP by mid-2020, at which point a pandemic should be contained. This estimate is subject to a significant degree of uncertainty with risks skewed to a potentially larger impact.
The effect should not be significant enough to trigger a broader economic malaise, but could this finally push Governor Poloz over the line to proactively stimulate the economy in his next rate call?
