Alan Greenspan, the former Federal Reserve chairman who led the central bank during the economic boom of the 1990s and early 2000s, has died at age 100. His tenure from 1987 to 2006 oversaw one of the longest periods of economic expansion in U.S. history, earning him the nickname 'The Maestro.' Greenspan's leadership shaped monetary policy during a transformative era for financial markets.

During his Federal Reserve chairmanship, Greenspan navigated the dot-com boom and presided over steady job growth and rising stock markets. His approach to monetary policy, emphasizing market-driven interest rates, influenced how central banks worldwide manage economic cycles. The tools and frameworks he helped develop continue to inform modern monetary policy decisions today.

Greenspan's legacy grew complex as the 2008 financial crisis emerged after his retirement, leading to debates about his role in housing market dynamics. While he championed deregulation and market confidence, critics argue his policies contributed to systemic risk buildup. His death marks the end of an era that defined both prosperity and vulnerability in modern finance.

The passing of Alan Greenspan concludes a remarkable career spanning seven decades of American economic policy. His influence on 2008 financial architecture remains debated, but his impact on central banking tools and market psychology is undeniable.
