JAKARTA  (Reuters) - Indonesia's finance ministry said on Thursday it planned to raise 2 trillion rupiah (S$283.5 million) from debt sales, to help finance a budget deficit that is forecast at 2.5 percent of gross domestic product.

The ministry plans to sell treasury bills maturing in 2010, as well as fixed-rate bonds maturing in 2016, 2024 and 2038, respectively.

Southeast Asia's biggest economy is well ahead in its 2009 funding requirements. It had raised around 80 trillion rupiah (S$11.36 billion), or 80 percent of its full-year target for bond sales.

The head of treasury department, Rahmat Waluyanto, said earlier this week that the ministry was not yet certain whether it would raise its bond sales target for 2009.

The government announced a 73.3 trillion rupiah fiscal stimulus package earlier this year to help contain the impact of global economic downturn and spur economic growth.

The central bank has forecast economic growth of 3-4 percent this year. It cut its benchmark policy by 25 basis points to 7.25 percent on May 5, bringing total rate cuts to 2.25 percentage points since December, to drive growth and boost bank lending.
