Greece was hit with another financial headache Friday after Fitch Ratings slashed its credit rating on the country’s debt because of mounting concerns about the government’s ability to get a handle on its debt.

Fitch, one of the world’s big three ratings agency, lowered its rating by two notches, to BBB-, and said that the outlook on the country remains negative.

The downgrade means Greek debt remains investment grade — but only just. Another downgrade would put Greece’s debt at junk status — an ignominious position for a country using the euro.
