"The essence of the agreement is that it will be beneficial for everyone, especially for Greece itself. The country’s second bailout program expires on Tuesday, so we've got 48 hours. I'm sure that we will settle the issue," de Guindos told Spain’s Expansion newspaper.
The minister added that Greece’s Sunday decision to limit cash withdrawals and introduce restrictions on various financial transactions was critical to the situation, but should not be upheld for a long time since the banking system is the backbone of the economy.
Athens has so far rejected every proposal by its international lenders and announced a national referendum on July 5 for voters to decide whether to accept the new bailout deal offered by the creditors.
A failure to sign a new agreement on the debt may lead Greece to a default and potential exit from the Eurozone.
