Longer-dated bonds suffered the most, with the 2045 issue  down by 0.8 cents in the dollar, the biggest drop since Wednesday last week.

The Turkish lira hit its weakest level against the dollar in nearly a month on Tuesday, with the central bank's move the previous day, aimed at boosting credit, and concerns about developments in Syria weighing on the market.

"The negative market response to the credit incentives can be attributed to concerns that the administration intends to rely on the same tools as on previous occasions to generate stronger economic momentum," Piotr Matys, emerging markets forex strategist at Rabobank, wrote in a research note.

"Such measures will not lead to well-balanced and sustainable growth over the long-term horizon, but perhaps the goal is to boost growth over the 12 month horizon and call early elections next year?"
