If “more extensive” means piecemeal limited commitments that will eventually be exhausted, the scheme runs the risk of creating losses (just as the Bundesbank would have suffered losses had it engaged in limited defense of weak ERM currencies).
Si «más amplias» significa compromisos limitados poco sistemáticos que eventualmente se agotarán, el esquema corre el riesgo de crear pérdidas (como las que hubiera sufrido el Bundesbank si hubiese participado en defensas limitadas de las monedas débiles del MEC).
