The world’s financiers and finance ministers have descended on the
annual forum in Davos, Switzerland, at another perilous moment, with the
sovereign debt woes in Europe sapping strength from emerging markets and
threatening global growth. Every nation’s rebound is at risk, including that of the United
States — a particular concern for President Obama, who wants to trumpet the
country’s renewed strength during his re-election campaign. Lael Brainard, America’s top financial diplomat, landed Thursday
in Switzerland to help coax the European negotiations along. As the Treasury
under secretary for international affairs, she has the urgent task of helping
to persuade the Europeans to head off a financial crisis by building a firewall
to quiet the markets once and for all — and doing so without any formal role in
their negotiations. It is at times an awkward role, but the stakes are enormous,
not just for the United States but for preservation of the euro zone and its
currency. Ms. Brainard, 49, operates mostly behind the scenes, in private
phone calls and discreet visits — 17 trips to Europe alone in the last two
years. “They trust her, they reach out to her, they talk to her for ideas
and to get us to engage,” said Timothy F. Geithner, the Treasury secretary, who
is also in Davos this week.
