William White

William White served as Chief Economist at the Bank for International Settlements (BIS) from 1995 to 2008. He became one of the few voices at official international financial institutions to warn consistently about the dangerous buildup of financial imbalances — excessive debt, housing market speculation, and lax financial standards — in the years leading up to the 2008 crisis. His annual BIS economic reports and speeches at Jackson Hole were notable for their warnings, but received little attention from policymakers who were confident in their ability to manage financial stability. After the crisis validated his concerns, he became a prominent critic of zero interest rate policies and their long-term consequences. His analysis of how prolonged monetary accommodation generates debt hysteresis — where cumulative debt burdens slow the economy's capacity to respond to rate normalization — has influenced academic and central bank discussions about the limits of unconventional monetary policy.
