Group of 20 leaders focused their response to Europe's financial crisis on stabilising the region's banks, raising pressure on German Chancellor Angela Merkel to expand rescue measures as contagion engulfed Spain.
As United States President Barack Obama called after-dinner talks with euro-area leaders at the G20 summit in Mexico, the Treasury Department's top international negotiator, Lael Brainard, said Europe was making an effort to "break the feedback loop" between banks and government debt, the link that is worsening Spain's woes.
"We're seeing a notable shift in European discussion" towards spurring economic growth and "laying out a path to financial union", Brainard said as the two-day summit began yesterday at the resort of Los Cabos.
G20 chiefs met as Spain's borrowing costs soared to a euro-era record and elections in Greece failed to damp the threat of contagion.
Merkel, who heads Europe's largest economy and rejects pooling euro-area debt or boosting deficit spending, said she would defend her policies with "good arguments" as world leaders press Europe to stamp out the debt crisis now in its third year.
