The 10 Billion Myth

Every few weeks I have the same conversation with a senior banker who is thinking about moving. The question comes in different forms, but it is always fundamentally the same. Is my bank going to survive? Is the 3 billion franc house I joined six years ago going to be swallowed by a tier-two competitor? Is the 8 billion boutique I am looking at a real opportunity or a slow-motion liquidation?

Underneath all these questions sits a single number that has taken on almost mythological status in the Swiss market. Ten billion francs of assets under management. The line below which, according to industry consensus, a private bank cannot reasonably expect to be independent a decade from now.

The consensus is wrong. Not completely wrong. But wrong in a way that matters, because it is causing good bankers to make bad career decisions and good boards to reach for the wrong solutions.

The Consolidation Numbers Are Real. The Interpretation Is Not.

The headline figures are accurate. Switzerland had roughly 160 private banking institutions in 2010. By the start of 2024, the KPMG and University of St. Gallen annual study counted 85. By the end of 2025 the number is expected to fall below 80. The recent deal flow backs this up: J. Safra Sarasin acquired Saxo Bank in the largest Swiss private banking transaction in more than a decade. Union Bancaire Privée absorbed Société Générale Private Banking Switzerland. Gonet and ONE swiss bank completed their merger.

So far, so expected. The industry is shrinking. The narrative writes itself. Small banks are disappearing, therefore small banks cannot survive, therefore any institution below ten billion is a future casualty.

This is where the analysis stops for most observers, and where it should actually begin. Because the same KPMG study reached a conclusion that received almost no attention in the subsequent press coverage. After analysing geographic and product diversification across Swiss private banks over the 2015 to 2024 period, the researchers identified two distinct business models that delivered higher and sustainable profitability. Not one. Two.

The first model was the large bank with a significant international presence and comprehensive service offering. The second model — which is the one almost nobody is discussing publicly — was the smaller bank based only in Switzerland with a very focused service offering. Not a big bank. Not a national champion. A focused, semi-local, specialised boutique. Under 10 billion in many cases. And delivering sustainable profitability while the middle of the market consolidates around them.

The HSG finding is not an opinion piece or a sell-side research note. It is a ten-year dataset. And it confirms what anyone spending time inside these institutions already knows. Size is not the binding constraint. Clarity is.

What Actually Kills a Private Bank Under 10 Billion

In my day-to-day work placing senior bankers, I see three failure patterns, and they appear together more often than separately.

The first is a cost-to-income ratio stuck above 80 percent. Only 31 percent of Swiss private banks achieved a return on equity above their cost of equity in 2024. Almost two-thirds of banks reported a worse cost-income ratio last year than the year before. A 3 billion franc boutique running at 65 percent cost-income is in a stronger position than a 15 billion franc institution running at 88 percent. The market has just not caught up with that observation yet.

The second pattern is positional ambiguity. When I read the public-facing materials of a private bank and cannot articulate in one sentence who their target client is, their next five years are going to be difficult. Half the mid-sized Swiss banks still describe themselves as providers of global wealth management to successful individuals and their families. This phrase means nothing. The boutiques that are thriving all pass the one-sentence test. Bergos is a German-speaking European family house. Reichmuth is a Swiss entrepreneur and family-office specialist with a partnership structure and no external shareholders. These institutions picked a lane and committed to it. Their size is not the point. Their identity is.

The third pattern is the inability to attract or retain genuinely senior bankers. A bank that cannot offer a clear platform proposition, cannot pay competitively because of a stretched cost base, and cannot articulate its next five years to a prospective Managing Director will lose its best people. Every bank I work with that has lost its senior bench over the past three years is, without exception, a bank with one or both of the first two problems.

The Implication for Senior Bankers

If you are a senior relationship manager inside an institution that does not demonstrate clarity of positioning, cost discipline, and a credible ability to attract and retain senior talent, the consolidation question is not academic. It is personal. The banks that score badly on all three attributes are the ones that will be sold, restructured, or quietly wound down over the next five years.

The useful question is not whether your employer will be independent in 2030. The useful question is whether your employer deserves to be. If the honest answer is no, the further question is whether you move now — on your own terms, with your book intact and your optionality at its peak — or whether you wait until the decision is made for you by a board you did not select.

Swiss private banks under 10 billion francs of AUM will not disappear as a category. The undifferentiated ones will. The specialised, well-run and well-capitalised ones will perform better than the current consensus expects. Size is a weak predictor of survival. Clarity of positioning, cost discipline, and the ability to attract and retain genuinely senior bankers are the variables that actually determine the next five years.

The 10 billion myth is comforting because it is simple. The truth is more useful, and more demanding.
