Abstract
We examine the leading role of the United States in the global equity markets by building
daily snapshots of lead-lag price discovery networks using high-frequency country
ETF returns. We find that the centrality of the U.S. equity market has been waning over
time. Consistent with an explanation of gradual information diffusion, we empirically
show that the shift to a multipolar system in the global equity markets can be explained
by changes in information supply and demand. Using the COVID-19 pandemic as an
exogenous shock, we document a causal relationship between news and country-specific
price discovery network centralities.
