[4] Tietmeyer was nominated by the government of Chancellor Helmut Kohl to become a member of the board of directors of the Deutsche Bundesbank in 1990, with responsibility for international monetary issues, organisations and agreements.

[7] At the time Tietmeyer forecast that the common currency would lead to painful internal economic adjustments for member states with trade deficits cumulating into debt.

Commentator David Marsh in late 2012 drew attention to that forecast as he highlighted "the significant internal devaluations of their currencies though a sharp fall in unit labor costs" which Ireland, Spain, Portugal, Italy and Greece, for example, have suffered in the European sovereign-debt crisis of 2008 onward.

[8] Tietmeyer published more than 100 articles on the subject of economics and was the recipient of many prestigious awards and prizes and was a member of the Pontifical Academy of Social Sciences.

From January until March 2000, with former president Roman Herzog and former federal judge Paul Kirchhof, Tietmeyer led an independent commission to investigate the CDU donations scandal.
