‘‘Greece, which had the highest peak deficit of any eurozone country, has done the most to balance its books,’’ a Fitch statement said. ‘‘However, it still has a long way to go before debt starts to fall and it complies with’’ European Union deficit regulations.

Meanwhile, Athens on Tuesday saw its borrowing costs dip slightly in an auction of 26-week Treasury bills. The public debt management agency said it raised €812 million ($1.1 billion) at an interest rate of 4.27 percent — compared to 4.3 percent in last month’s auction.

Although unable to raise money by selling long-term debt, Greece maintains a market presence through regular short-term Treasury bill auctions.
