According to the State Bank of Pakistan (SBP), following the loan from the IMF, the country’s foreign exchange reserves now stand at above $15.0431 billion.The IMF, among other things, requires the government to leave the rates to market forces of demand and supply. This means the central bank would not fix the rate to keep the rupee artificially inflated, something it did in the tenure of former finance minister Ishaq Dar. Both traders and end users have been closely monitoring dollar rates since the present government’s started its term in August 2018. The dollar was trading at Rs124 when the PTI government was sworn in, but rose by more than 29% to its current value since then.As Pakistan formally enters the IMF programme, the policy of market-driven exchange rates will remain in place. The State Bank of Pakistan will neither fix the exchange rate nor completely leave it to market forces, Dr Reza Baqir, the SBP governor, said at a recent press conference. “We will keep a close eye on its movement and intervene to avoid any speculative movement and volatility,” he said. Dr Baqir termed the regime to be a ‘market-based exchange rate system’.
