Financial institutions have drastically changed over the last decade and further evolutions are yet to come.  Regulatory constraints have driven most of these transformations, but the financial revolution is much more complex and cannot be  limited to the latter. Business models must be adapted within each business line and operating models must take into account industrial partnership, outsourcing or strategic alliances.

  • Strategic deployment
  • Financial performance
  • Business process optimization
  • Digital banking

Comply with regulations

In recent years, the financial sector was forced to implement regulations (Basel III, MiFID II, EMIR, AIFM, FATCA), some of which are not yet implemented (TTF, UCITS V).This complex environment is constantly monitored and analyzed by Sia Partners’ experts.

Reinvent the business models
