Several media reports said prices of onions — a common ingredient in Indian cooking — have doubled since July.India is one of the top exporters of onions globally. During the 2018 calendar year, the country sold 2.2 billion kilograms — worth around $514.3 million — of fresh and chilled onions overseas, according to official trade data. But onion exports accounted for just 0.16% of the country’s overall exports last year, the data showed.Still, the export ban is not the only move that Indian authorities have taken to tame soaring prices given the importance of the vegetable to domestic consumers.The government has tried to bring down domestic prices by releasing supplies from its national buffer stocks. It also set a minimum export price on onion shipments earlier in September at a level it had hoped would discourage foreign buyers. The government also withdrew an export incentive in June.India’s slowing economyReduced farm output during the monsoon months also affects other industries in India, such as manufacturing and retail— which potentially could derail the momentum of an economy that’s already slowing down. In the April-to-June quarter, India’s economy grew 5% year-on-year — its weakest pace in six years as consumer demand and government spending slowed.That weakness in economic growth is part of the reason why many analysts are expecting the Indian central bank to cut interest rates two more times this year, even though the government has already cut corporate tax rates in an attempt to revive the economy.”We don’t think the RBI (Reserve Bank of India) is done with easing either, especially with Governor Shaktikanta Das recently hinting at more easing, which leaves little doubt about the RBI slashing rates again next week. The key question is whether it will be yet another bigger-than-usual cut?” ING economists wrote in a note last week.The Indian central bank has lowered its benchmark rate by a total of 1.1 percentage points since January — more than many of its regional peers.
