what still stands out to me about the CS AT1 situation is not just the loss itself but the sequence. bondholders wiped out before equity holders. that completely breaks the mental model most people operate with when they think about debt being safer than equity.
AT1s were always marketed as higher risk debt, but in a stress scenario they behaved like equity on the downside without offering any of the equity upside. that asymmetry is what makes them genuinely dangerous for retail investors who didn’t read the fine print.
The HDFC angle in that piece is interesting too. Not directly exposed but pulled into the narrative through questions about governance and leadership judgment. That’s the second-order effect that most people miss when a major credit event happens. It’s not just about who held the instrument. It reshapes how institutions are perceived and what questions get asked.
The regulatory dimension is what I keep coming back to. The Swiss regulator made a discretionary call that overrode what most market participants assumed was a fixed contractual hierarchy. One decision, made overnight, reshaping outcomes for thousands of investors. That’s not a market risk. That’s a regulatory risk, and it’s much harder to model or price.
It also set a precedent globally. Other regulators now know this is available to them as a tool.
The takeaway for anyone building a fixed income portfolio is clear. Yield cannot be evaluated in isolation. Where you sit in the capital structure matters enormously, and in edge cases the distance between being a senior secured creditor and being an AT1 holder is the difference between recovery and zero. The extra yield on instruments like AT1s exists for a reason. Most retail investors who chased that yield did not fully understand what they were being compensated for. Disc: No AT1 exposure personally.
