The global spillovers of unconventional monetary policies on tail risks

This article analyzes the risk spillovers of UMPs of four major central banks on the expectations of a market crash in foreign equity markets. The empirical findings show that forward guidance measures exhibit a significant cross-border impact on tail risks. Other expansionary UMPs are innocuous on inducing risk spillovers to other economies. A classification of reversal UMPs into contractionary and tapering provides opposite conclusions: contractionary UMPs shocks exhibit a strong and negative cross-border impact on the tail risks of other economic areas, contrary to tapering announcements. Both the Fed and ECB unconventional policies induce significant risk spillovers with similar magnitudes.
