Abstract
The legal concept known as the clausula rebus sic stantibus doctrine is discussed. Based on the restrictive interpretation of this doctrine, it is unlikely that any Swiss court would permit the termination or amendment of an agreement because of the introduction of the euro. The introduction of the euro may cause some derivatives transactions to lose all or part of their commercial rationale. It is therefore of interest to determine whether the clausula rebus sic stantibus doctrine or any other rule of Swiss law would enable the affected party to terminate the agreement. The situation of Ecu-denominated contracts is also considered.
