Key Takeaways:
South Korea's KOSPI Composite Index tumbled 6% intraday Tuesday, its steepest single-day decline since March 2020, as the death of former Federal Reserve Chairman Alan Greenspan at age 100 triggered a broad risk-off move across Asian equity markets.
Greenspan, who led the US central bank from 1987 to 2006, died Monday from complications of Parkinson's disease, his wife Andrea Mitchell said. His 18 1/2-year tenure included the 1997-1998 Asian financial crisis, during which the Fed helped stabilize South Korea by persuading US banks to roll over short-term loans to the country. That history made his passing a significant moment for regional markets that still bear the institutional scars of the contagion.
The KOSPI's 6% intraday slide outpaced declines across other Asian benchmarks, with traders pointing to South Korea's export sensitivity to global demand and its vulnerability to capital flow reversals during periods of heightened uncertainty. The selloff coincided with weakness in the South Korean won, adding pressure on an economy that relies heavily on energy imports and semiconductor exports.
Greenspan was widely celebrated as the "Oracle" and "Maestro" during his tenure, credited with presiding over the longest US economic expansion on record — a 10-year boom from March 1991 to March 2001 that saw unemployment briefly drop below 4% for the first time since 1970. Inflation, which had bedeviled the US economy during the 1970s, remained remarkably dormant throughout his chairmanship. But his reputation suffered after the 2008 financial crisis, when critics blamed his easy-money policies and faith in lightly supervised financial markets for fueling the housing bubble that nearly toppled the US banking system. Greenspan later acknowledged he "made a mistake" in assuming banks could regulate themselves.
His crisis management skills were tested early in his tenure. Just two months after taking office in August 1987, the Dow Jones Industrial Average plunged 22.6% on Black Monday, October 19. Greenspan won credit for restoring calm by assuring Wall Street the Fed would supply as much liquidity as needed. That playbook — decisive intervention during market stress — became a template for central bank crisis response worldwide.
For Asian markets, the Greenspan era carries a dual legacy. His Fed's response to the 1997 crisis — arranging emergency loans to Thailand and rolling over South Korean debt — deepened US engagement in regional financial stability. Yet the easy-money policies that followed also contributed to the capital flows that amplified the region's boom-bust cycles. His death at 100 has revived debate about central bank power and its limits, a discussion that resonates particularly in emerging markets that bore the brunt of the 1997 contagion.
The KOSPI's decline Tuesday reflects not just a reaction to Greenspan's passing but broader anxiety about the global economic outlook. South Korea's export-dependent economy is particularly exposed to slowing demand from China and the US, its two largest trading partners. The Bank of Korea faces the challenge of supporting growth while keeping inflation in check, a balancing act that Greenspan himself navigated during his long tenure. His famous warning about "irrational exuberance" in December 1996 — two words that sent markets reeling — serves as a reminder of how central bank communication itself can become a market-moving force.
