Alan Greenspan, Former Fed Chair, Dies at 100

Alan Greenspan, the former chair of the Federal Reserve who served from 1987 to 2006 under four presidents, has died at the age of 100.

Greenspan was a towering figure in global finance, credited with the 'Great Moderation' but also blamed for policies that contributed to the 2008 financial crisis.

His death prompted debate over the 'Greenspan put' and whether markets can still count on central bank intervention.

Tributes have poured in from economists and policymakers.
