In 2003, Fink helped New York Stock Exchange CEO Richard Grasso resign, who faced widespread criticism for his $0.19 billion compensation package. In 2006, Fink led the merger with Merrill Lynch Investment Management, doubling Blackrock's asset management investment portfolio. That same year, Blackrock acquired Stuyvesant Town-Peter Cooper Village in Manhattan for $5.4 billion, marking the largest residential real estate transaction in U.S. history. When the project ended in default, Blackrock clients, including the California pension and retirement systems, lost approximately $0.5 billion.
The U.S. government signed contracts with Blackrock to aid in its recovery after the 2008 financial crisis. Fink's long-standing relationships with senior government officials raised questions about potential conflicts of interest in government contracts awarded without competitive bidding. Blackrock's contracts facilitated relationships with Obama's first Treasury Secretary, Tim Geithner, and other members of the Obama economic recovery team. In 2016, Fink aspired to become Hillary Clinton's Treasury Secretary. Blackrock also hired many former government appointees to strengthen its ties with the federal government.
In December 2009, BlackRock acquired Barclays Global Investors, making it the world's largest asset management company. Despite Fink's significant influence, he is not widely known apart from frequent appearances on CNBC. BlackRock paid Fink $23.6 million in 2010, and $36 million in 2021. By 2016, BlackRock managed $5 trillion in assets and had 12,000 employees in 27 countries.
In 2016, Fink received the ABANA Achievement Award in New York. The award recognizes individuals in banking and finance who demonstrate outstanding leadership and actively promote professional collaboration between the U.S. and the Middle East and North Africa.
In 2018, Fink was ranked 28th on the Forbes Global Power People list.
During the 2020 coronavirus pandemic, the Federal Reserve sought BlackRock's help to purchase distressed securities, echoing the actions taken in 2008.
