The Military authorities more or less legitimized the black market. Under Prussia Siege law (which was declared at the start of the war) the Military governors where more or less running everything, a complex modern ecnomy and suprisingly enough they really were not the qualified to do so. They did deals with various speical intrests, the industialists got large, very large profits (even by ww1 profiteering standards) unions in munitions industries got high wages, and special black market allowances, the general population get screwed. They defecit spending and stacking up and bills to pay at the end of the war, was basically handled by saying when we win the French and British will pay. Versailles would have been nothing to what the Germans would have imposed. German government debt was solved by hyper inflation. Worked well for the government , industrialists and those with wealth rather than money.Certainly. And so did the Germans as well eventually.
In the German case there were centrally planned measures that seem to denote a certain casual disregard for the realities of agriculture, i.e. avoidable mistakes that didn't help any, like the great German 1915 "Pig Murder":
