The IMF and pretty much all western capitalist democracies, were overjoyed when the Macri administration assumed power. When Macri's pro-business agenda faltered, due to deteriorating domestic economic conditions and extreme weakness in the peso, the IMF extended help in the form of the $57B standby loan. We all know the IMF does the bidding of western capitalist democracies that fund its existence, so the standby loan was no surprise. The western capitalist democracies wanted to preserve the Macri administration, as they viewed CFK and her dishonest, socialist governance as disastrous.
The IMF loan has not been worthless to the average Argentine. To the extent it has supported Argentine asset prices and supported the peso, it has been beneficial. Yes, both of the above have collapsed, but that collapse could have been worse. The Merval could have falled 80% in dollar terms and the peso could be at 70. The IMF loan gave the Macri regime the resources to support both.
In addition, any honest analysis must include consideration of the alternatives. If the Argentine government had kept printing money, as CFK did, the peso would likely be at 70 today. Argentina was running an enormous fiscal deficit, and that has to be paid for somehow. CFK printed money to pay for it, which forced up inflation and weakened the peso. Macri borrowed to finance the fiscal deficit, while trying to reduce it, which has resulted in large debt to GDP balance.
When your spending is above your revenue, the difference has to be made up somehow.
In addition, Argentina still has about $20B in foreign exchange reserves. So it's not like the entire $57B is spent and/or "gone." A portion of it sits in the equivalent of Argentina's bank account.
Whether the standby loan has been "worth it," is a different argument and I will not enter it. But keep in mind that to the extent Argentina does not pay interest, it receives free money. To the extent Argentina restructures this loan, it gets economic benefit on the back of the IMF. To the extent, Argentina is able to renegotiate the IMF loan terms in its favor, the average Argentine will benefit. Again, whether that is "worth it," is a matter for each person to decide for themselves. But my guess is that the standby loan will not be paid in a fashion economical to the IMF - and that means Argentina will receive financial benefit - which will inure to the average Argentine.
Keep in mind the old saying, "If you owe the bank $100, it's your problem. If you owe the bank $100 million, it's the bank's problem."
