April 26 (Reuters) - Top exporter India's rice export prices fell to their lowest level in more than three months this week on subdued demand and ample supplies, while Thailand's prices remained largely flat.
India's 5% broken parboiled variety
"Demand is very weak from Asian and African countries. Some exporters are paying lower duties on exports and offering rice at a lower price to overseas buyers," said an exporter based in the southern state of Andhra Pradesh.
New Delhi imposed a 20% export duty on parboiled rice exports in August 2023 to control domestic rice prices.
Meanwhile, Vietnam's 5% broken rice
"The slowdown in purchases by domestic rice processors has put downward pressure on domestic paddy rice prices," the trader added.
Vietnam's markets will be closed from Monday through Wednesday for national holidays.
Thailand's 5% broken rice prices
In Bangladesh, rice output from the summer crop is likely to hit 20.50 million metric tons, up from 20 million metric tons, as farmers raised acreage to cash in on higher prices, an agriculture ministry official said.
The summer-sown crop, also known as "Boro", usually contributes more than half of Bangladesh's typical rice production of around 37 million tonnes.
