In September, El Salvador became the first country to allow consumers to use the cryptocurrency in all transactions, alongside the US dollar.
The decision led to large-scale protests over fears it would bring instability and inflation to the impoverished Latin American country.
Bitcoin has lost about half its value since November.
The IMF has warned President Nayib Bukele of the risks the cryptocurrency poses to the country, stressing that it would be difficult to get a loan from the institution.
The board’s directors have now “urged the authorities to narrow the scope of the Bitcoin law by removing Bitcoin’s legal tender status”, according to a statement.
When El Salvador introduced the virtual currency as a legal tender, the government released a new digital wallet app, giving away $30 (£22) in Bitcoin to every citizen. More than 200 new cash machines were also installed across the country.
It means that businesses, wherever possible, are now obliged to accept the digital coins as payment.
Bitcoin is a controversial currency in part because its value can fluctuate significantly – it has risen and fallen dramatically over the past year.
Bitcoin was trading at about $37,000 on Tuesday, having lost about half its value compared to the record of $67,734 hit in November.
