AYLESBURY, England (Reuters) - Group of Seven finance officials agreed on Saturday to redouble efforts to deal with failing banks and gave a green light to Japan's drive to galvanize its economy.
British finance minister George Osborne said the finance ministers and central bankers meeting 40 miles outside London focused on unfinished bank reforms, with signs that plans for a euro zone banking union are fraying.
"It is important to complete swiftly our work to ensure that no banks are too big to fail," Osborne told reporters after hosting a two-day meeting in a stately home set in rolling countryside.
"We must put regimes in place ... to deal with failing banks and to protect taxpayers and to do so in a globally consistent manner," he said.
The emergency rescue of Cyprus after a near meltdown in March served as a reminder of the need to finish an overhaul of the banking sector, five years after the world financial crisis began.
Germany has come under pressure to give more support to a banking union in the euro zone. The plan could help strengthen the single currency area, but Berlin worries it may pay too much for future bank bailouts if it signs up to a scheme to wind up stricken lenders.
While the first step - to create a single bank supervisor under the European Central Bank - looks set to be in place by mid-2014, a second pillar, a 'resolution' fund to close failed banks, is in doubt. And there is little prospect that a single deposit guarantee scheme will ever see the light of day.
A senior U.S. Treasury official said the talks at the 17th-century Hartwell House zeroed in on the need not just for better bank supervision but also to clean up balance sheets so lending can pick up.
"There was a sense of urgency among the euro area participants," the official said.
German Finance Minister Wolfgang Schaeuble countered that the euro zone was no longer the main risk to the world economy.
As at previous international meetings, Japan escaped any censure for printing money on a scale that has pushed the yen sharply lower.
Osborne said the G7 - the United States, Germany, Japan, Britain, Italy, France and Canada - reaffirmed that fiscal and monetary policy should be aimed at domestic concerns, not currency manipulation.
"We will not target exchange rates," Osborne said. "I would say that the statement by the G7 of earlier this year was a successful statement and one that has been held to."
The yen hit a four-year low against the dollar on Friday, driven in part by Japanese investors shifting into foreign bonds, a move that had been expected since the Bank of Japan unveiled a massive stimulus plan.
But having urged Tokyo for years to do something to revive its economy, other world powers are not in a strong position to complain now that it is doing so. Then there is the fact that central banks such as the Federal Reserve and Bank of England have printed money in the way the Bank of Japan is.
Japanese Finance Minister Taro Aso said the G7 had leveled no criticism at Japan's monetary policy but Schaeuble said there had been "intense discussions" and that the situation would be monitored carefully.
Debate has also heated up about the need for governments to ease up on austerity, something Germany, Britain and Canada view with caution but Washington, Paris and Rome favor.
Osborne said there was less disagreement about whether governments should focus on debt-cutting or growth-boosting measures than is commonly assumed.
"Everyone is clear that there needs to be credible medium-term fiscal consolidation ... We also agreed that there needs to be flexibility," he said. "Growth prospects remain uneven and we can't take the global recovery for granted."
But his suggestion before the meeting that it should consider what more monetary policy could do to support economic recovery appeared to fall on deaf ears.
"There wasn't any call to do more," European Central Bank chief Mario Draghi told reporters after the meeting.
"It is quite clear that all central banks have done a lot, each one within its own mandate. So (the meeting) was just taking note of this ... All of us have really been active."
Several officials from visiting delegations questioned why Britain had called the gathering just three weeks after they and others met at International Monetary Fund meetings in Washington, but Bank of England Governor Mervyn King said the informal nature of the discussions had paid dividends.
"Freed from burden to agree a communiqué, the principals engaged more with each than I can recall before and as a result genuinely made real progress in taking forward some of the questions and issues that are facing the G7," he said.
