Not really 'ignore' as in the country isn't complying with the agreed terms. El Salvador is just taking advantage of certain conditions in the loan agreement that were ambiguous or perhaps flexible. Somehow, the country is able to skirt the condition that prohibited its public sector to further purchase Bitcoin.

I've also read that the same IMF loan has a condition that El Salvador's Fidebitcoin Trust Fund will have to be liquidated by July 2025. We'll see whether the country complies or not. So far, El Salvador has already complied in declassifying Bitcoin as currency.
