Global stocks, the euro and peripheral euro zone bonds all rose on Monday, lifted by a wave of optimism that Greece and its international creditors will strike a last-minute deal that will see Athens avert default.
Greek Prime Minister Alexis Tsipras will meet the heads of the European Commission, European Central Bank and International Monetary Fund on Monday ahead of a summit of euro zone leaders later in the day aimed at reaching a deal over debt talks.
The chief-of-staff to European Commission President Jean-Claude Juncker called the latest proposals from Greece a "good basis for progress", while EU Economic Commissioner Pierre Moscovici said he was "convinced" agreement will be reached.
Financial markets appeared willing to give the protagonists in the saga the benefit of the doubt. German stocks jumped 2.5% and the 10-year yield on Spanish and Italian bonds fell as much as 12 basis points.
"The most likely outcome, with a 75% probability, is a deal," Credit Suisse analysts said in a note on Monday.
"An unfortunate but predictable feature of European crisis decision-making is that such deals are only ever made at the last minute, 'at the edge of the abyss'," they said.
