We Audit the Code, but Who Audits the Conscience?
There is a particular moment in every financial crisis when the language shifts. Suddenly, the numbers people used to reassure themselves—capital ratios, stress test results, exposure limits—begin to sound like incantations rather than measurements. They repeat them louder, as if volume alone could restore the credibility that silence has already surrendered.
Swiss Finance Minister Karin Keller-Sutter, in her recent public rebuke of parliamentary plans to ease UBS capital requirements, has chosen a different incantation. She speaks of taxpayer risk. Not competitiveness. Not market share. Not the delicate art of keeping a global banking giant satisfied while the world watches. She speaks of the people who would ultimately foot the bill if the architecture fails.
The fact that she must speak at all tells us something uncomfortable about how quickly institutional memory fades.
The Weight of a Balance Sheet
Let me establish some context that the parliamentary debate seems determined to ignore. UBS holds approximately $1.6 trillion in assets on its balance sheet. Switzerland's GDP is roughly $880 billion. These two numbers, placed side by side, create an algebraic truth that no amount of regulatory sophistication can fully escape: UBS is simply too large for Switzerland to let fail, and too large for Switzerland to save without catastrophic fiscal consequences.
This is the classic too-big-to-fail condition, and it carries a moral hazard that extends far beyond the usual academic hand-wringing. When a bank knows—truly knows, deep in its risk models and its capital planning—that the sovereign stands behind it, that knowledge alters behavior. It seeps into lending decisions, into trading desks, into the quiet calculus of how much risk one can afford to take when the downside is socialized.
Based on my audit experience examining governance models in decentralized systems, I've learned that the most dangerous vulnerabilities are never the ones written in code. They are the ones embedded in incentives. The smart contract executes exactly as designed; the problem is that the design itself contains hidden assumptions about human behavior. Switzerland's capital regime is no different. The question is not merely what the rules require, but what they signal to the bankers who must internalize them.
Keller-Sutter's opposition to easing capital rules is, in this sense, a defense of a certain kind of institutional clarity. She understands that capital requirements are not just buffers against loss; they are messages about the acceptable boundaries of risk-taking. Loosen them, and you are telling the market—and more importantly, telling UBS itself—that the lessons of Credit Suisse's collapse are negotiable.
The Political Economy of Prudence
The parliamentary pressure to relax capital rules is not difficult to understand. UBS is Switzerland's flagship financial institution, and its international competitiveness is genuinely constrained by higher capital requirements than those faced by American and European peers. There is a real tension here between financial safety and financial competitiveness, and it would be dishonest to pretend otherwise.
But I find myself troubled by the asymmetry in how this debate is being framed. The parliamentarians pushing for relaxation can cite competitive pressures, shareholder returns, and the danger of falling behind in global markets. These are concrete, measurable concerns. Meanwhile, the risks they are asking the public to absorb are abstract—until they are not. The Credit Suisse collapse in March 2023 was not abstract. It was a 167-year-old institution that went to zero in a matter of days, and it was only prevented from causing a global banking panic by a shotgun wedding that no one had wanted or planned.
The deeper issue, though, is what this political pressure reveals about the durability of regulatory resolve. Regulatory frameworks are not like smart contracts. They do not execute automatically. They require constant reinforcement from the political class, and that reinforcement is itself subject to the same short-term incentives that create financial crises in the first place.
We audit the code, but who audits the conscience?
The Counterintuitive Case for Staying Put
Here is where I would like to offer a contrarian observation, one that cuts against both the parliamentary push for relaxation and the reflexive defense of the status quo.
The conventional argument for maintaining strict capital requirements rests on the protection of the financial system—and by extension, the Swiss economy and its taxpayers. This is a sound argument, and Keller-Sutter is right to make it. But there is a less discussed benefit to maintaining strict requirements that has nothing to do with crisis prevention and everything to do with competitive positioning.
Switzerland's comparative advantage in global finance has never been about speed, aggressiveness, or scale. It has been about stability, discretion, and reliability. These are not the qualities that emerge from a race to the bottom in regulatory standards. They are the qualities that emerge from being the institution that can be trusted with wealth that needs to remain safe, whatever the global environment throws at it.
In a world of increasing regulatory fragmentation and geopolitical uncertainty, the value of a genuinely conservative, genuinely stable financial center is likely to increase, not decrease. The parliamentarians who want to loosen capital rules in the name of competitiveness are, I suspect, competing on terrain where Switzerland cannot win against much larger players. But they may be undermining the terrain where Switzerland has historically dominated.
There is also a less discussed dynamic at play here, one that should concern anyone who cares about the integrity of financial systems. When regulators relax capital requirements in response to political pressure, they are not just changing the rules of the game. They are changing the culture of the game. They are signaling to the entire ecosystem that rules are negotiable when the right people complain loudly enough. That lesson gets learned, internalized, and eventually priced into behavior in ways that no amount of supervision can fully reverse.
The Blind Spots of Both Sides
I should also note what both sides of this debate seem to be missing. For the parliamentarians pushing for relaxation, the blind spot is the assumption that UBS's international competitors are necessarily operating with appropriate capital levels. The race-to-the-bottom logic that drives regulatory arbitrage is not a sign of healthy competition; it is a sign of collective myopia. Just because American or European banks can operate with thinner buffers does not mean they should, or that matching them would be prudent.
For the Finance Minister's side, the blind spot is perhaps more subtle. Strict capital requirements, maintained indefinitely, can create their own form of moral hazard. They can give policymakers a false sense of security, a belief that because the buffers are high, the system is safe. But capital ratios are a lagging indicator of risk. They tell you about what happened before, not what is happening now. The Credit Suisse collapse was not caused by insufficient capital on paper; it was caused by a catastrophic loss of confidence that no capital buffer could have withstood.
The deeper question, which neither side seems willing to confront, is whether Switzerland should continue to host a global systemically important bank at all—at least at its current scale. This is the question no political actor wants to ask, because the answer might require making choices that are genuinely difficult.

Building for the Plain
I come back to a principle that has guided my thinking through the booms and busts of the last decade: build not for the peak, but for the plain. The peak is where you test the limits of what is possible. The plain is where you have to live with the consequences.
The parliamentary push to ease UBS capital requirements is a peak-building argument. It assumes the conditions that make risk attractive will persist indefinitely. The Minister's resistance is a plain-building position, grounded in the understanding that financial systems must be designed to survive the seasons they cannot predict.
There is something deeply ironic, I think, in watching Switzerland—a country that has made a virtue of its independence, its stability, and its careful management of risk—debating whether to compromise those qualities for the sake of competitive advantage. If Switzerland cannot resist the siren song of regulatory relaxation, what chance does anyone else have?
We audit the code, but who audits the conscience? The answer, for now, appears to be a single finance minister with the courage to remind her colleagues that the real asset they manage is not UBS's market share, but the trust that allows a small country to host one of the world's largest financial institutions. That trust is a form of capital too, and it is far harder to replenish than a capital buffer.
The question for the parliament is not whether UBS can afford to hold more capital. It is whether Switzerland can afford to be seen as the kind of country that would ask.
