The central bank of Indonesia is optimistic that the country's economy will accelerate at a faster pace this year, top official of the lender said here Wednesday.

Governor of the Central Bank Agus Martowardojo said he is confident that the Southeast Asia's biggest economy will expand between 5 to 5.4 percent this year.

That compares with 5.02 percent gross domestic product growth last year, according to the national statistics bureau.

Martowardojo said the lender forecasts the country's economy will grow more than 5.2 percent at the third and fourth quarter of this year after expanding steadily 5.01 percent in the first and second quarters.

He said there were some activities in the second quarter which make the contribution to consumption, which account for 57 percent of the GDP growth, shift to July-September period.

"We see that Indonesian economy is in a good condition," he said at the central bank headquarters.

The policy maker has put loosening policy on the table as the inflation has been in check amid relatively stable rupiah against U.S. dollar, supported by a rapid inflow of capital and sound macro-economic fundamentals, according to Martowardojo.
