 The Indian rupee had a bad few days against the dollar, ending at its lifetime closing low last week. Now there's quite a lot at play here. There's a weak domestic market, plus there's that jump in crude oil prices. But traders and banks are also getting ready for a possible dollar shortage. Back in 2022, the Reserve Bank of India, the RBI, undertook a $5 billion rupee swap that matures this week. And that potentially means that billions of dollars could be taken out of the banking system. So you've got the larger banks busy raising dollars now to try and avoid a crunch if that happens. Of course it is possible the Reserve Bank of India could decide to roll over the swap instead of allowing it to mature. Media reports suggest that most bankers are not expecting that. They are expecting it to mature as planned. It's worth saying as well though, the rupee stayed weak but flat towards the end of last week. Traders have told the news agency Reuters that the RBI is likely to be selling US dollars to protect the rupee from falling to a record low.
