Here he passed the diploma examination for business people with Erich Gutenberg in 1951. He then moved to the University of Cologne , where he worked with Gutenberg in 1953 with the dissertation "Delayed operational adjustment to changes in demand with homogeneous competition" to become a Dr. rer. pole. received his doctorate .

In 1959, Krümmel accepted Wolfgang Stützel's offer and moved to Saarbrücken University , where he wrote his habilitation thesis “Bank Interest - Investigations into the Price Policy of Universal Banks” in 1964 . The habilitation thesis, which was published as a book, quickly became known, particularly because of the discovery of the principle of "small price policy means", and advanced to become the standard work on price policy in banking .

Publications and other functions
Krümmel's habilitation thesis Bankzinsen - Investigations into the pricing policy of universal banks covers more subject areas than the title suggests. He first deals comprehensively with the term bank sales performance, by which he understands individual services and service conglomerates that the stronger side of the market describes as salable. He sees the commitment commission as a price reference basis for a fictional inventory. He realized that credit expansion, the insolvency risks may increase for banks, because from 1950 to 1963 were 11 bank failures on large exposures due. He divided the bank customers into three bargaining power groups , namely into customers with no, with moderate and with outstanding bargaining power. Krümmel showed that the simultaneous planning of costs and revenues in banking operations, which is necessary for profit maximization, is not possible. Finally, he also dealt with typical banking preferences .
In his book Financing Risks ( Financing Risk ) in 1966 he provided the explanatory approach for a bank's loan offer. According to this, the free liable equity capital determines the maximum individual loan offer, which is still just acceptable given a default probability of approximately zero. If a certain small maximum probability of default were exceeded, this would lead to the rejection of even smaller loans. Krümmel, who published numerous articles in specialist journals, published a theoretical model of the domino effect in the bank run in 1984 . In 1991 he was co-author of the book Allfinanz : Structural Change in the Markets for Financial Services .
Krümmel has been co-editor of the magazine “ Kredit und Kapital” since 1977 and since 1984 also of the research on savings, giro and credit systems . Between 1974 and 1979 he was a member of the banking structure commission of the Federal Ministry of Finance and since 1979 director of the Institute for Savings, Giro and Credit Systems at the University of Bonn . Between 1979 and 1981 he was rector of the Rheinische Friedrich-Wilhelms-Universität, where he retired in 1981 .
Krümmel was a member of the Teutonic Order and its German Lord Master of the Ballei Deutschland der Familiaren of the Teutonic Order and at the same time chairman of the German Lords Association.
