BRUSSELS/ATHENS (Reuters) - Greece's international creditors signaled on Wednesday they were ready to compromise to avert a default even as a defiant Athens warned it might skip an IMF loan repayment due this week.
Prime Minister Alexis Tsipras agreed in a telephone call with German Chancellor Angela Merkel and French President Francois Hollande on the need for an immediate solution to the long-running debt negotiations involving a lower primary budget surplus target for Greece, a Greek official said.
Their third call in a week took place before Tsipras met European Commission President Jean-Claude Juncker in Brussels to hear the terms of a plan drawn up by the European Commission, the European Central Bank and the International Monetary Fund after a meeting of leaders chaired by Merkel on Monday.
With time running out, and looking to draw a line under four months of acrimonious negotiations, the creditors have effectively come up with a take-it-or-leave-it offer.
However, Tsipras has produced a plan of his own and said he intended to discuss that document in Brussels, calling on euro zone partners to show some "realism" and urging a deal that would let Greece escape from "economic asphyxiation".
Neither man made any public comment as Juncker put his arm around the leftist Greek leader and led him into their meeting.
Hardline German Finance Minister Wolfgang Schaeuble said an initial look at Greece's reform suggestions indicated that talks aimed at securing an aid-for-reforms deal will take time.
"I have no information that anything decisive has changed in terms of substance," he said at an event in Berlin.
Looking for a compromise, the creditors suggest that Greece should post a budget surplus before interest payments of one percent of gross domestic product this year and two percent in 2016, instead of 3 percent and 4.5 percent under the terms of the current plan, sources familiar with the proposal said.
The sources said the Greek government, elected in January pledging to end years of bitter austerity, had offered a primary surplus of 0.8 percent this year and 1.5 percent next year.
However, the relatively small gap in headline numbers masks tougher unresolved issues on how to achieve the fiscal targets.
Athens has offered to curb early retirement to save on pension payouts but the lenders wanted cuts in supplementary pensions, a smaller civil service and an easing of private sector layoffs to make the economy more competitive.
It was not clear if the creditors - euro zone governments, the IMF and the ECB - will show any flexibility in those areas.
Sounding more upbeat and conciliatory than Schaeuble, Hollande suggested an agreement was within reach.
"We are a few days or hours away from a possible deal on Greece," he told a conference at the Paris-based OECD think tank. "Asking too much of Greece could stifle growth. But asking too little would have consequences for the euro zone as a whole."
Locked out of international bond markets, Greece has not received any cash from its trio of creditors since last August and its coffers are all but empty.
It is due to pay back the IMF 300 million euros ($335 million) of loans on June 5, but a spokesman for the ruling Syriza party raised the possibility that it would not.
"If there is no prospect of a deal by Friday or Monday, I don't know by when exactly, we will not pay," Nikos Filis told Mega TV on Wednesday.
Greece has three other repayments, totaling about 1.23 billion euros, due to the IMF in June after the one on Friday.
ECB President Mario Draghi made clear the central bank would not help to bridge Athens's acute funding gap by letting Greek banks buy more short-term government debt until the lenders agreed the bailout was back on track and began releasing some of the 7.2 billion euros in outstanding aid.
"There should be a credible perspective for a successful conclusion of the current review and that would imply, by the member countries, a disbursement," Draghi said in Frankfurt. "That would be the condition for the Governing Council to consider ... a lifting of the t-bills ... and we are not there."
Tsipras, who faces a backlash in his party if he is forced to retreat on his anti-austerity drive, said before leaving Athens he would push his government's proposal at the Brussels meeting.
"Today, more than ever before, it is necessary that the institutions, and mainly the political leadership of Europe adopt the realism that the Greek side has been showing for the past three months," he told Greek television.
Greece owes a total of about 320 billion euros, of which about 65 percent is to euro zone governments and the IMF, and about 8.7 percent to the ECB.
Many euro zone capitals appear unwilling to offer Athens too much slack, fearing it would undermine fiscal rigor across the bloc and boost radicals in their own countries clamoring for an end to years of austerity.
If Greece skips the IMF payment, the immediate consequences are hard to predict. However, officials have warned for months that a default could ultimately push Greece out of the single European currency and unleash possible turmoil on world markets.
White House economic adviser, Jason Furman, said a Greek default was a "potential accident" in waiting.
"It would be a mistake to think it would be just contained to Greece," he told the OECD conference, saying policymakers had been wrong-footed in recent years by contagion from the U.S. sub-prime debt crisis.
With cash running out and the economy seizing up as the government halts payments to suppliers and curtails investment, Tsipras faces intense pressure to capitulate soon to prevent an outright economic collapse.
His supporters have suggested that rather than go back on his campaign pledges, he might prefer to call a new election or a referendum to let the Greek people decide on the way forward.
Dutch Prime Minister Mark Rutte said an exit of Greece from the euro zone could still not be excluded and that bridging the gap between Athens and its creditors remained difficult.
"I do believe they are working very hard to get somewhere, but at the same time they (the Greeks) have made so many promises in the elections and afterwards in parliament ... that it's difficult to bridge the gap," he told Reuters in Paris.
