Indian export rice prices fell to their lowest in more than two months this week due to a weaker rupee and muted demand, while mounting supplies from an ongoing harvest weighed on Vietnamese rates.
Top exporter India saw rates for its five per cent broken parboiled variety fall to $366-$372 per tonne, the lowest since 26 March, from $368-$373 last week.
The rupee has fallen more than six per cent this year, prompting exporters to cut rates.
"Even after lowering prices, there is no improvement in demand," said an exporter based at Kakinada in the southern state of Andhra Pradesh.
India's rice production could surge to a record as farmers are expanding the area under paddy because of good monsoon rains.
Demand weakened for Vietnam rice as well, with rates for the country's five per cent broken rice slipping to $450 per tonne, the lowest in nearly two months. Prices had hit an eight-year high of $475 on 4 June as rains hampered harvest.
"Demand from foreign buyers has weakened this week," a trader based in Ho Chi Minh City said.
Domestic supplies are building up amid the summer-autumn harvest, other traders said, adding that Vietnam could export 2.3-2.5 million tonnes from the harvest after securing enough for local consumption.
Prices of Thailand's benchmark five per cent broken rice eased to $505-$525 a tonne on Thursday, from $505-$533 last week, with traders attributing the slip to a stronger Baht.
"Demand remains flat because our prices are higher than India and Vietnam," said a Bangkok-based rice trader.
Concerns over supply lingered after a drought hampered production earlier this year.
"More rains this monsoon season will vastly improve supply, but the market is still slightly concerned, hence the high prices," another rice trader said.
Stocks in Bangladesh, the world's fourth-biggest rice producer, will likely fall by 8.33 per cent in 2021 because of the coronavirus pandemic, threatening food security, the Food and Agriculture Organisation said earlier this month.
