The ongoing debate about financial regulatory reform and the looming European debt crisis are two dominant themes in Treasury & Risk's 100 Most Influential People in Finance list this year. The 2012 list includes lots of movers and shakers in Washington, reflecting the efforts there surrounding derivatives and money-market fund regulations, the Volcker Rule, convergence with international accounting standards, corporate tax reform and the federal deficit. There are also a number of global leaders on this year's list as companies watch to see whether the eurozone's problems will derail the global economic recovery. The heart of the list, though, remains the corporate finance executives—CFOs, treasurers, risk officers and others—who continue to come up with better ways to get the job done and innovative approaches to help their companies flourish.
