Swiss banking still gets discussed as if the whole story can be reduced to one weekend in March 2023. That weekend does matter. On March 19, 2023, FINMA approved the takeover of Credit Suisse by UBS and noted that the Swiss National Bank was granting further liquidity assistance backed by a federal default guarantee.[1] But the SNB data answers the title’s question more directly: Switzerland is more concentrated at the top, while domestically focused banks still held 73% of domestic loans and 69% of domestic deposits at end-2024; UBS held 24% of domestic loans and 24% of domestic deposits, according to Table 1 of the SNB Financial Stability Report 2025.[3]
The Federal Department of Finance states that the Credit Suisse merger into UBS was completed on June 12, 2023, and that the federal guarantees connected to the rescue package were terminated with effect from August 11, 2023.[2] The analytical question in 2026 is therefore not whether Credit Suisse was rescued. It is what the official data says about the structure that followed. The answer is balanced: Switzerland has one globally active Swiss bank in UBS, but it does not have a one-bank domestic market.
Key Takeaways
- The break point was March 19, 2023, when FINMA approved the UBS takeover of Credit Suisse.[1]
- The emergency guarantee phase ended on August 11, 2023, when the federal guarantees tied to the rescue were terminated.[2]
- The Swiss system is more concentrated at the top, because Switzerland no longer has two globally active Swiss banking groups.
- The domestic market is still broader than UBS: at end-2024, domestically focused banks held 73% of domestic loans and 69% of domestic deposits, while UBS held 24% and 24%, respectively.[3]
- The main watchpoints now are UBS integration, parent-bank capital reform, liquidity reform, and mortgage risk, rather than the rescue transaction itself.
The Dates That Define The New Era
The post-Credit Suisse period is best understood through a short sequence of official dates.
| Date | Official development | Why it matters |
|---|---|---|
| March 19, 2023 | FINMA approved the takeover of Credit Suisse by UBS.[1] | This ended the old two-global-bank Swiss model. |
| June 12, 2023 | The merger of UBS and Credit Suisse was completed, according to the Federal Department of Finance.[2] | This started the full integration phase. |
| August 11, 2023 | The federal loss-protection guarantee and the federal guarantee for SNB liquidity assistance loans were terminated.[2] | This marked the end of the rescue-guarantee phase. |
| April 10, 2024 | The Federal Council adopted its report on banking stability and said the too-big-to-fail regime should be strengthened.[4] | This turned the Credit Suisse case into a reform agenda. |
| June 6, 2025 | The Federal Council set parameters for legislative and ordinance changes, including capital, recovery and resolution, senior-manager accountability, FINMA powers, and liquidity measures.[5] | This made the reform agenda more specific. |
| April 22, 2026 | The Federal Council adopted the dispatch on the Banking Act revision and amended the Capital Adequacy Ordinance, with ordinance changes coming into force on January 1, 2027.[6] | This moved key capital measures from policy design toward parliamentary debate and implementation. |
Takeaway: the crisis phase was short, but the regulatory consequences are still unfolding.
What Changed, And What Did Not
Switzerland lost one of its two global banking pillars
The biggest structural change is clear: Credit Suisse no longer exists as an independent Swiss banking group. Before March 2023, Switzerland had two globally active systemically important banks. After the merger, it had one. That changes how investors, regulators, and counterparties think about concentration risk.
It also changes how the Swiss banking system is judged internationally. There is now a larger gap between the global role of UBS and the domestic role of the rest of the system. That does not mean UBS controls every part of Swiss banking. It means UBS is the single institution through which Switzerland’s global-banking risk is now most visibly concentrated.
The domestic model underneath it remained broader
The Credit Suisse rescue did not change the fact that Swiss domestic banking is still heavily shaped by mortgage lending, deposit franchises, and interest-rate sensitivity. The SNB defines domestically focused banks as banks with domestic loans above 50% of total assets or with a prominent role in the domestic deposit market; it includes the domestically focused systemically important banks PostFinance, Raiffeisen Group, and Zürcher Kantonalbank in that discussion.[3]
That distinction matters. Credit Suisse changed the top of the system more than it changed the domestic banking model below it. The official structure table shows a market that is more concentrated than before, but still distributed across cantonal, cooperative, and other domestically focused institutions.
What SNB Data Says About The Swiss System
The structure is more concentrated at the top
The SNB’s end-2024 structure data is the clearest snapshot of the post-merger system. The table below uses the SNB’s categories from Financial Stability Report 2025, Table 1, p. 19.[3] Leverage ratio exposure is included because it shows balance-sheet scale under the leverage framework; it is not the same thing as domestic market share.
| SNB category | Share of domestic loans | Share of domestic deposits | Leverage ratio exposure |
|---|---|---|---|
| Domestically focused banks | 73% | 69% | CHF 1,545 billion |
| Of which domestically focused systemically important banks | 26% | 30% | CHF 642 billion |
| UBS | 24% | 24% | CHF 1,380 billion |
| Other banks | 3% | 7% | CHF 549 billion |
Takeaway: UBS is central, especially by overall scale, but domestically focused banks still carry most domestic Swiss lending and deposits.
Profitability improved, but unevenly
The SNB says banking-sector profitability improved in 2024, with return on assets rising to 0.47% from 0.33% in 2023, excluding UBS’s 2023 negative-goodwill effect from the Credit Suisse acquisition. The same section says the improvement was driven by UBS, while return on assets for domestically focused banks fell by 8%, or 4 basis points, to 0.46%, mainly because net interest income declined.[3]
That matters because it shows the system did not become uniformly stronger after Credit Suisse disappeared. UBS’s reported profitability improved. The broader domestic bank group faced renewed pressure from lower net interest margins.
Liquidity buffers are high, but confidence risk remains central
The SNB reports that banks’ liquidity coverage ratios averaged around 185% over the previous 12 months, while domestically focused systemically important banks averaged around 160%. The same liquidity section says those levels were well above regulatory minimum requirements, but also stresses that outflows can be rapid once confidence breaks and may exceed standard LCR assumptions.[3]
This is one of the most important post-Credit Suisse lessons. The question is no longer only whether banks meet regulatory liquidity ratios. It is whether their liquidity position, collateral preparation, and contingency planning would hold up under a faster confidence shock.
Credit quality is still stable overall
The official credit-quality picture remains calm. The SNB says system-wide credit-loss expenses decreased slightly in 2024 to 0.1% of outstanding loans. It also says UBS’s overall loan-portfolio credit quality remained robust, with 1.0% of the total loan portfolio impaired at end-2024, while domestically focused banks’ impaired-loan share remained at 0.7%.[3]
The nuance is useful. The former Credit Suisse corporate loan book in UBS’s Swiss division still affected UBS credit-loss expenses relative to pre-acquisition levels, but the SNB data does not point to broad system-wide credit deterioration.[3]
Mortgage risk remains the main domestic macro watchpoint
The SNB continues to flag elevated risk appetite in mortgage lending. For new mortgages in 2024, it says the share for which debt-service and maintenance costs would exceed rents at a mortgage rate of 3% was 30% for households and 14% for commercial borrowers in residential investment property segments. The SNB says both were above the average for 2012 to 2024.[3]
This is where analysts should still spend time. The Credit Suisse episode changed the structure of global Swiss banking. It did not remove the domestic mortgage cycle from the risk map.
What Analysts Should Track Now
- UBS integration through 2026. The SNB says UBS expected to complete its integration and restructuring programme by the end of 2026, while integration costs were still weighing on profitability in 2024.[3]
- Parent-bank capital reform. The Federal Council’s April 2026 proposal would require systemically important banks to fully back participations in foreign subsidiaries with CET1 capital at the Swiss parent bank; it also states that Parliament can debate the Banking Act proposal from summer 2026.[6]
- Implementation timing. The April 2026 Federal Council release says the Capital Adequacy Ordinance amendments come into force on January 1, 2027, while the foreign-participation proposal includes a seven-year transition period if there are no parliamentary delays.[6]
- Liquidity reform. The Federal Council’s June 2025 package included measures to increase the potential for obtaining liquidity via the SNB and to require better collateral preparation; the April 2026 release says liquidity-shortage information requirements are being limited to systemically important banks.[5][6]
- Domestic mortgage affordability. This remains one of the clearest official warning areas in Swiss financial-stability analysis.[3]
The reform agenda in plain English
The old four-gap summary can be made simpler. The policy debate now has three practical strands.
First, capital at the Swiss parent bank. The Federal Council argues that foreign subsidiaries of systemically important banks must be fully backed with CET1 capital at the parent-bank level so that valuation losses abroad do not immediately weaken the Swiss parent’s capital ratios. In April 2026, the Federal Council estimated that the new regulations would strengthen UBS parent-bank CET1 capital by approximately USD 20 billion based on the status quo, while also saying the actual CET1 shortfall would have been around USD 9 billion if the rules had been introduced on January 1, 2026.[6]
Second, liquidity and collateral preparation. The lesson from 2023 is that reported liquidity buffers are not the whole story. The SNB’s 2025 report says outflows can move faster than LCR assumptions, while the Federal Council’s 2025 package points to stronger preparation for liquidity support from the SNB and other central banks.[3][5]
Third, resolution and supervision. The June 2025 Federal Council package included higher requirements for recovery and resolution plans, earlier FINMA intervention powers, possible pecuniary administrative sanctions, and a senior managers regime for banks.[5] That is a broader supervisory agenda, not just a UBS capital discussion.
Additional Tier 1 capital should be treated separately. FINMA said in March 2023 that the extraordinary government support triggered a complete writedown of around CHF 16 billion of Credit Suisse AT1 debt.[1] But in April 2026, the Federal Council said it would not proceed with proposed AT1 adjustments for the time being, because it considered it more appropriate to wait for international developments.[6]
Methodology And Limits
- This article uses Swiss official sources for time-sensitive dates and regulatory claims: FINMA, the Swiss National Bank, the Federal Department of Finance, and Federal Council releases.
- The structural, profitability, liquidity, credit-quality, and mortgage figures come primarily from the SNB Financial Stability Report 2025. The report says it is based on data as at May 31, 2025, while the core system-structure table used here is a snapshot as at end-2024.[3]
- This article does not attempt a bank-by-bank Swiss ranking because Swiss public disclosure is more aggregate and category-based than the U.S. Call Report framework.
- Where this article discusses the post-merger structure, it is referring to the Swiss system after March 19, 2023 and especially the structure visible in SNB data as at end-2024.
The clearest reading is that Switzerland now has more concentration at the top, more regulatory urgency, and more dependence on getting the UBS framework right. But the domestic market has not been reduced to UBS alone. SNB data still shows domestically focused banks holding most domestic loans and deposits.
That means analysts need to track two stories at once. One is UBS as the single globally active Swiss bank. The other is the Swiss domestic system as a mortgage-, deposit-, and liquidity-sensitive market still led by domestically focused institutions. Watching only one of those stories will give an incomplete view.
FAQ
Is UBS now the only major Swiss bank?
UBS is the only globally active Swiss systemically important bank after the Credit Suisse merger. But it is not the only important Swiss bank domestically. The SNB’s end-2024 table still shows domestically focused banks holding most domestic loans and deposits.[3]
Why does leverage ratio exposure matter in the SNB table?
It helps show scale. UBS’s domestic loan and deposit shares were both 24% at end-2024, but its leverage ratio exposure was CHF 1,380 billion, close to the CHF 1,545 billion shown for all domestically focused banks together. That is why UBS can be systemically central without holding most domestic Swiss loans or deposits.[3]
What is the biggest regulatory issue to watch after Credit Suisse?
The most visible issue is parent-bank capital backing for foreign participations. The Federal Council’s April 2026 proposal would require full CET1 backing at the Swiss parent bank, with parliamentary debate expected from summer 2026 and a seven-year transition period if there are no delays.[6]
Is the mortgage-risk issue mainly a Credit Suisse legacy problem?
No. Mortgage affordability is a broader Swiss domestic-banking issue. The SNB’s 2025 report continues to flag elevated risk appetite in mortgage lending, especially in residential investment property segments.[3]
Can Swiss banks be compared directly with U.S. or EU bank datasets?
Only with care. The SNB provides strong aggregate and category-level analysis, but Swiss public data is less like U.S. Call Reports or EU bank-level transparency exercises. For Switzerland, the safer approach is to read official aggregate signals first and avoid forcing the data into a bank-by-bank template it does not support.
