You seem to think IMF deals with FGS only, actually the conditions also apply to FMS, that's why they also have to report their revenues monthly to the FGS, you should read
this report by the IMF which is Somalia review on June 17, they mentioned "FMS" 52 times, and do you know what the FGS said in that review report "Finance Ministers across all the Federal Member States (FMS) are fully committed to supporting the economic reforms needed to underpin the HIPC process, and technical cooperation has gathered pace". also in the report "A significant portion of budget support (an increase of 0.4 percentage points of GDP compared to 2021) is expected to be shared with FMS".
The problem is IMF were negotiating with Bayle but the new man said: nah I'll just risk complicating the matter, probably don't know how strict the IMF is and how they expect you to follow their guidelines.
