Robert Rubin was sworn in as the seventieth U.S. Secretary of the Treasury in January 1995 in a brisk ceremony attended only by his wife and a few colleagues. As soon as the ceremony was over, he began an emergency meeting with President Bill Clinton on the financial crisis in Mexico. This was not only a harbinger of things to come during what would prove to be a rocky period in the global economy; it also captured the essence of Rubin himself -- short on formality, quick to get into the nitty-gritty.

From his early years in the storied arbitrage department at Goldman Sachs to his current position as chairman of the executive committee of Citigroup, Robert Rubin has been a major figure at the center of the American financial system. He was a key player in the longest economic expansion in U.S. history. With In an Uncertain World, Rubin offers a shrewd, keen analysis of some of the most important events in recent American history and presents a clear, consistent approach to thinking about markets and dealing with the new risks of the global economy.

Rubin's fundamental philosophy is that nothing is probably certain. Probabilistic thinking has guided his career in both business and government. We see that discipline at work in meetings with President Clinton and Hillary Clinton, Chinese premier Zhu Rongji, Alan Greenspan, Lawrence Summers, Newt Gingrich, Sanford Weill, and the late Daniel Patrick Moynihan. We see Rubin apply it time and again while facing financial crises in Asia, Russia, and Brazil; the federal government shutdown; the rise and fall of the stock market; the challenges of the post-September 11 world; the ongoing struggle over fiscal policy; and many other momentous economic and political events.
