Greek bonds rated ‘junk’ by Standard & Poor’s

Doubts intensify
S&P lowered its rating on Greece’s debt to BB+ considering as a riskier place to invest. Some financial institutions have rules prohibiting from investing in "junk" bonds.
Greece's 2-year and 5-year yields surged highly expensive for the country to borrow from the debt market and it is higher than many emerging market economies.
Greece denounces it does not correspond with the real data of the Greek economy.
The downgrade causes the major indexes in Europe and the US slid from 2% to 3.8%. Shares in Greek banks slumped with the largest one-day fall in bank shares for 18 months.

‘Prohibitive' rates
Greece cannot go to the markets to raise funding, because of "prohibitive" interest rates.
Greece wants 40bn euros (£34bn) from eurozone governments and the International Monetary Fund (IMF) to shore up its finances. The cost of borrowing on the money markets has reached record levels amid investor concern over whether the bail-out package will be agreed.

S&P warned holders of Greek debt that they only had an "average chance" of getting their money back in the event of a debt restructuring or default. Also, Greece's weak long-term growth prospects made it less credit-worthy.
