India's sugar production could rise 1.5 percent in 2018/19 to a record 33 million tonnes, increasing inventories in the world's second-biggest producer and putting pressure on local prices, a producers' body said on Friday.

The record production could force New Delhi to continue incentives for overseas sales of sugar into the next season, weighing on global prices, which are now trading near their lowest in four months.

In the first seven months of the 2018/19 marketing year that started on Oct. 1, mills have churned out 32.1 million tonnes of sugar, 3 percent more than in the same period a year earlier, the Indian Sugar Mills Association (ISMA) said in a statement.

India produced 32.5 million tonnes of sugar for the whole of the 2017/18 marketing year.

"The sugar recovery in northern India has been substantially better than the sugar recovery achieved in the last season," the association said.Years of bumper cane harvests and record sugar production have hammered domestic sugar prices, making it hard for mills to pay monies owed to farmers, who form an influential voting bloc.

India's money-losing sugar mills have run up a record $4.38 billion in arrears to 50 million cane farmers, who have gone unpaid for their produce for more than a year.

To bring down cane arrears and reduce rising inventories, New Delhi has been providing incentives to mills for overseas sale of sugar and set an export target of 5 million tonnes.

But mills are likely to export only 3 million tonnes of sugar in the current marketing year due to a drop in global prices, according to ISMA estimates. That means India's sugar inventory levels will rise to 14.7 million tonnes at the beginning of the new season on Oct. 1, 2019, up 37.4 percent from a year ago, the trade body said.

The industry has been hoping the 2019/20 season's output could drop due to higher ethanol production and a drought in the western state of Maharashtra, the country's second-biggest sugar-producing region.
