"In this case study we found that the Rebel Alliance would need to prepare a bailout of at least 15%, and likely at least 20%, of GGP in order to mitigate the systemic risks and the sudden and catastrophic economic collapse. Without such funds at the ready, it likely the Galactic economy would enter an economic depression of astronomical proportions."
The destruction of the death star may reduce the burden since it would no longer incur operational costs. On the other hand, it did establish the operators as a tax authority.
I would expect lending banks to be covered by printed money followed by corresponding inflation. On the other hand, if the lenders are isolated among relatively few planets/systems, they could be overtaken by the government and those systems would bear the brunt of the losses.
The most likely outcome wouldn't be galactic recession, but return to chaos and war as the grievances between systems would now be unchecked.
But you're right that it can act as an enforcement agency, a tax collector of sorts. Or maybe an extortionist: "Pay up or we destroy your planet!".
