the possible idea is since Gael Finance is a corporate umbrella company owned by both ministry of finance and ministry of commerce in Aruia. Gael Finance would do the hostile take over and pull the strings to finalize the take over.
This leading to complete control over one of the prime banks in Ainslie.
Ostehaar, since during your war period Gael Finance established and started owning banks across Gael. It was this mediator body the Aruian government used to hand a loan to Ostehaar to fund their either war or recovery from war. Which the crash could lead to a complete derail.
The end game here is that its discoered that the minister of finance who is also the minister of commerce, a labor party member had his hands involved in this mishap. Because liquidizing Gael Finance and Bank Gaels assests would lead to a copmlete economical chaos it became an international body with the pressure of the affected nations, reparations would be given to several countries, Aruia would be shut down its offices and with the eye of Gael Finance open the Aruian Commerce and Trade center instead which is a body used by the government but owned by Gael Finance. Aruias bank is solely used to print and maintain its currency soveireiginity and that is it.
Through this whole process Aruia starts from the end of the 80s to the end of the 90s liberalization process led by Valerio Del'falco.
The Aruian public feels humilated by the action of its government lose faith in its current government who was mainly left wing, become very hostile to socialist idealogy which strengh the liberal and center parties. Leading Aruia to being a very center liberal country.
