But, when Iran's oil minister met with his counterparts from Venezuela, Iraq and Qatar on Wednesday, the meeting resulted in his stating that the "ceiling" proposed by Russia and Saudi Arabia on production would be a useful step towards stabilising the market. Iran is faced with a dilemma. On the one hand, it expects to increase output to at least recover the market share that it had before sanctions were imposed. On the other hand, more supply would reduce prices even further - and Iran desperately needs a higher return on its crude oil in order to invest in creaking, decades-old refining and extraction infrastructure. Thus it has welcomed the deal without promising to join it. But, certainly, the implication that all stakeholders at least were on board with the idea of a production ceiling deal sent oil prices up by five per cent on Wednesday. While geo-political tension in West Asia means that none of the participants likes each other very much at the moment and there are conflicting views on whether the development would result in higher oil prices, there is little doubt that the producers' incentives to agree on a deal are sharp. Also on Wednesday, the credit rating agency, Standard & Poor's, cut the rating of a number of oil-exporting countries - including Saudi Arabia's, which was slashed by two points from A+ to A-.
This movement in the oil market's structure has made the future path of oil even more difficult to pin down than usual. But this confusion comes at a difficult time. The Union Budget for 2016-17 is being written, and one of the crucial variables in it is the global oil price. The government's finances have gained considerably from the fall in global oil prices - the estimated price of a barrel of oil in the ongoing financial year's Budget was $70. The difference between that and the actual price will allow the government to do a lot better than it otherwise would. Many traders are expecting a barrel of Brent crude oil to be between $40 and $45 in the summer, but the oil major BP expects it to be closer to $60 by the end of the calendar year 2016. The finance ministry should play it safe and ensure that a higher rather than lower oil price is chosen in the Budget, so that there are no unpleasant surprises to the fiscal arithmetic somewhere in the middle of the coming year.
