Keynesian theory, manifested among the others in financing of deficit spending provided an excuse to politicians to increase spending without raising taxes and thus to resign from the self-imposed discipline in the form of balanced budgets that existed be-fore this theory, a big advocate of which was also James Buchanan. The answer to the debt crisis in Europe are fiscal reforms. The adoption of the re-formed Stability and Growth Pact, together with fiscal treaty is aimed at long-lasting breaking with the practice of conducting an irresponsible fiscal policy and constitute an attempt to return to an unwritten balanced budget rule. The major aim of this article it to prove that the sovereign debt crisis is the final proof of the need to return to the concept of a balanced budget rule proposed, inter alia, by James Buchanan back in the 70’s of last century.
