India imports nearly 80% of its oil but the weakening rupee, together with a 16% oil price rise, has boosted the bill for IndianOil, Hindustan Petroleum and Bharat Petroleum in the past three months from an estimated $220 million a day to $300 million.
The oil companies have to go to the open forex market to sell rupees to buy dollars to pay for the imports but the Reserve Bank of India (RBI) has pledged a forex swap window sufficient to meet the firms entire daily dollar requirements.
Oil and gold are the two main contributors to Indias $88 billion current account deficit. The government, which has cracked down on gold imports and raised duty, is now considering selling some of its 558 tonnes reserves to curb import demand.
The announcement on Thursday by the RBI triggered the biggest one-day bounce in the rupee in more than 25 years from a record low of 68.83 to the dollar to 66.60.
However, the rebound still leaves the rupee 16.5% below its level on May 23, the day before the US Fed first hinted it might scale back its unprecedented quantitative-easing programme.
Fears that the cheap funds bonanza might be coming to an end triggered a sell-off by foreign investors across emerging markets, which has seen currencies from the Turkish lira to Brazilian real depreciate precipitously.
The run on the rupee, exacerbated by fears the slowing economy will scare away investors, has made it the worst-performing emerging market currency this year. That prophecy has become self-fulfilling capital outflows topped $2.2 billion in August as global funds unloaded equities and local currency bonds.
The RBIs intervention to provide dollars to the oil companies has stemmed the fall for the time being, but its being looked at as a quick-fix, says Amir Khan, corporate dealer at Currencies Direct.
The danger is that they have to take an estimated $9 billion a month from foreign reserves of $280 billion so they cant go on for very long and thats when its going to spiral out again.
With the dramatic fall weve seen, 70 to the dollar cant be ruled out and given the currency is performing this badly on tapering rumours, it could slide even further once tapering starts.
He adds: Theres not much India can do the only option is to open up the economy and bring in structural reforms but it looks like theyre unwilling to do it.
As the crisis of confidence deepens, global banks have turned bearish. Bank of America has warned that the rupee could slump to 75 to the dollar by end-2014. UBS and Standard Chartered recently cut their 2013-2014 growth forecasts to 4.7% from 5.5%.
StanChart said it was concerned wholesale price inflation and the fiscal deficit could rise. The bank also cited a slowdown in production with a knock-on effect to the services sector that it expects to broaden as the year progresses, with little respite in sight in the face of rupee losses, higher rates and poor sentiment.
After a decade of strong growth of around 9% a year, the economy grew just 5% in the year to March. The RBI has cut its 6.5% projection for this year twice in the past six months but as recently as July 30 was still forecasting growth of 5.7%.
Markets are increasingly concerned about a negative feedback loop between the rupee and Indias fundamentals, StanChart analysts write in a recent report, but they stress that worries about a repeat of the 1991 balance-of-payments crisis when India was forced to airlift its gold reserves to secure an emergency IMF loan are overblown.
The rupees move upwards from 65 to the dollar to almost 69 was very rapid and did look like it was largely speculative in nature rather than actual dollar demand going through, says Priyanka Kishore, FX strategist at StanChart.
We will go back below 65 but Im less certain whether it can move below 65 into a firm position with sentiment stalling and people taking off their long positions trying to cap profits.
US non-farm payroll (NFP) data is very important from a Fed perspective and a lot of this move is to with the US dollar move. If we see NFP confirm that September tapering is happening, we could see USD/INR go back up from there, so near-term there is a down move and some consolidation.
Kishore says this does not change the overall fundamental story for India, which is slightly negative for the rupee, but stresses the currency is undervalued by 18% on a rear basis. She forecasts the rupee strengthening to 64 to the dollar for the fourth quarter, after a weaker third quarter at 68.
Kishore concludes: Valuations are very attractive and the current account is improving, and that will become more evident as we go into the fourth quarter.
So there are these economic stabilizers that are kicking in and once the market knows the extent of Fed tapering, were probably going to get a relief rally in Asian currencies.
