Johns Hopkins Carey Business School Associate Professor Alessandro Rebucci, an expert in international finance, applied macroeconomics, and financial crises, offers his perspective on the recent volatility of the stock market. Rebucci, who earned his PhD in economics from the University of London, held research and policy positions at the International Monetary Fund and the Inter-American Development Bank before coming to Johns Hopkins.
QUESTION: What do you see as the main underlying cause, or causes, of the recent cooling of the stock market?
ALESSANDRO REBUCCI: The U.S. market was unanimously assessed as being generously valued and was ripe for a correction. Last week’s wage data release was the catalyst. Delivering firmer evidence of much-awaited (or feared) wage growth, it prompted an upward revision in inflation and interest rate expectations, increasing uncertainty about the duration of the ongoing economic expansion. A protracted period of low equity price volatility, persistent doubts about fundamental valuations in cryptocurrency markets, as well as technical factors linked to pervasive use on automatic trading technology, all combined to generate a steep adjustment.
Is there reason for alarm in this recent trend, or is this mostly a reasonable and natural correction after unprecedented gains?
At this stage, the correction is healthy and part of a normal transition toward a period of higher interest rates, following a decade of ultra-low rates after the global financial crisis.
Reportedly, some investors are feeling nervous because the global economy is doing too well, which might strike some observers as paradoxical. Why the nervousness?
I would say that the global economy’s doing well is the reason why it can withstand the temporary blow from a global asset price correction. The fear is that the U.S. economy, already doing pretty well before the approval of the tax reform, might now end up overheating, forcing the Federal Reserve to hit the brakes too hard with higher interest rates than previously anticipated. Historically, this is how most post-war recensions came about.
What’s your estimate of how the market might behave in the months ahead?
We know that interest rates are going to continue to rise. The recent tax cut means much higher government borrowing, household consumption, and business investment, so also higher wages and inflation. The stock market will continue to adjust downward toward more realistic valuations or turn bear if the Fed fails to deliver on its balancing act. Volatility is back with a vengeance and here to stay.
