Government is keeping a watch on the global risk factors to the economy including Brexit, turmoil in the Middle East and spike in oil prices in the international market, Minister of State for Finance Jayant Sinha said today. "There are a number of risk factors that we routinely consider. We discussed, for example, what will happen with oil prices and turmoil in the Middle East. We discussed Brexit as well, along with the risk factors that India has," he told reporters on the sidelines of the Rajasva Gyan Sangam. On June 23, UK will vote on whether to remain in the 28-nation European Union or to leave. Britain's exit from the EU, or Brexit, is being debated globally as it could have implications for the international financial market and exchange rates. India has significant trade with UK as well as EU. It also receives large investments from the Europe. On the possible outcome of the UK vote, Sinha said: "It (opinion polls) is showing that it will be a close call." Another concern, he said, is the turmoil in the Middle East and its implications on the crude oil prices. As a net importer, India has significantly benefited from the recent low oil prices, which have now started inching up. The crude oil price has hit 11-month high of USD 50 per barrel. Sinha had earlier said that government's fiscal maths and inflation calculations would not be impacted if the oil prices stay below the USD 60 mark. India, which depends on imports to meet 80 per cent of its oil needs, will have to spend Rs 9,126 crore (USD 1.36 billion) more every year for increase of each dollar per barrel in crude oil. Besides, the rising crude oil trajectory impacts inflation and growth. "If oil prices stay in the range that most forecasters are expecting them to be, which is in the USD 40-60 dollar range, then I think we will be fine. If it goes beyond that range, then it becomes a question," Sinha had said earlier. India spent USD 63.96 billion on crude oil import in 2015-16, about half of USD 112.7 billion outgo in the previous fiscal and USD 143 billion in 2013-14. For the current fiscal, the import bill has been pegged at USD 66 billion at an average import price of USD 48 per barrel.
