The story

The 1994 ECU definition includes sterling and Danish-krone components; basket inclusion is distinct from later national euro adoption. [1]

Turning points

Ecu ems policy resolution

The December 1978 resolution specifies identical initial ECU and EUA value/composition and plans EMS establishment for 1 January 1979. [2]

Ems agreement signed

Inference: BIS dates signature of the EMS/ECU agreement in Basel to 13 March 1979, separately from the earlier planned January start. [3]

Defined ecu references replaced

Defined ECU references in legal instruments become euro references at 1:1 from 1 January 1999; an undefined ECU reference carries a rebuttable presumption. [4]
