The Case for Industry Led Governance

In the global debate over how to manage corporate conduct, the default response is often a call for state intervention. However, the Swiss banking sector is providing a high-profile counter-argument. Erol Bilecen, Head of Sustainable Finance at the Swiss Bankers Association (SBA), argues that while the State is essential for defining a broad framework, the stakeholders actually operating in the market are best positioned to define the technical specifics. A recent study conducted by HSLU on behalf of the SBA demonstrates that this "bottom-up" approach to regulation can be swifter, more factual, and more robust than traditional government mandates.

Rising to the Challenge of Greenwashing

The push for self-regulation was largely triggered by the "greenwashing" controversy that peaked in late 2022. As experts struggled to define what truly constituted a "sustainable" investment, the Swiss Federal Council issued a position paper setting clear expectations for the financial sector. Rather than waiting for a slow-moving legislative process to create a "regulatory monster" similar to those seen in the European Union, the SBA, alongside the Asset Management Association Switzerland and the Swiss Insurance Association, revised their existing codes of conduct to align with the government's goals.

A Rapid and Measurable Implementation

The findings from the September 2025 HSLU survey indicate that the industry has followed its commitments with concrete action. By the time of the study, 86 percent of Swiss banks had fully implemented the initial version of the self-regulation for portfolio management. Furthermore, 42 percent had already integrated the revised, more stringent guidelines, with an additional 42 percent in the final stages of adoption. This rapid transition suggests that the industry was highly motivated to establish credibility in the sustainable finance space before the state felt compelled to intervene.
