Unless Greece suddenly finds 1.6 billion euros ($1.7 billion) down the back of the sofa, it will miss its deadline to repay the International Monetary Fund (IMF) by 6 p.m. ET on Tuesday.
Given that the country's fiscal situation has become so dire that its banks are shut and citizens can only withdraw 60 euros a day from ATMs, this is unlikely. Also, when countries repay the IMF, they usually give the lender 24 hours notice, which has not been forthcoming.
Greek Prime Minister Alexis Tsipras seemed in defiant mode Monday night as he tweeted: "Having asphyxiated banks & denied extension request, is it reasonable to expect that IMF installment will be paid tomorrow?"
Here we look at why this isn't just another deadline for Greece.
