[merrily]

15. What part of "overly literal" is mystifying?

Geithner worked for Kissinger Associates in Washington for three years and then joined the International Affairs division of the U.S. Treasury Department in 1988. He went on to serve as an attaché at the Embassy of the United States in Tokyo. He was deputy assistant secretary for international monetary and financial policy (1995–1996), senior deputy assistant secretary for international affairs (1996–1997), and assistant secretary for international affairs (1997–1998).[10]

He was Under Secretary of the Treasury for International Affairs (1998–2001) under Treasury Secretaries Robert Rubin and Lawrence Summers.[10] Summers was his mentor,[18][19] but other sources call him a Rubin protégé.[20][21][22]

In 2001 he left the Treasury to join the Council on Foreign Relations as a Senior Fellow in the International Economics department.[23] He was director of the Policy Development and Review Department (2001–2003) at the International Monetary Fund.[10]

In October 2003, at age 42,[24] he was named president of the Federal Reserve Bank of New York.[25] His salary in 2007 was $398,200.[26] As President of the New York Fed, he served as Vice Chairman of the Federal Open Market Committee. In 2006, he also became a member of the Washington-based financial advisory body, the Group of Thirty.[27] In May 2007, he worked to reduce the capital required to run a bank.[24] In November he rejected Sanford Weill's offer to take over as Citigroup's chief executive.[24]

In March 2008, he arranged the rescue and sale of Bear Stearns.[18][28] As a Treasury official, he helped manage multiple international crises of the 1990s[21] in Brazil, Mexico, Indonesia, South Korea, and Thailand.[22]

Geithner believed, along with Henry Paulson (of Goldman Sachs), that the U.S. Department of the Treasury needed new authority to experiment with responses to the late-2000s (decade) financial crisis.[18] Paulson described Geithner as a "very unusually talented young man...[who] understands government and understands markets".[28]
