On 30 September 2026, the Swiss National Bank published balance sheet items as of end-August 2026 via its data portal. The release is part of the SNB’s regular monthly statistical reporting. Specific figures were not contained in the accessible summary of the publication.
The Swiss National Bank (SNB) published balance sheet items as of end-August 2026 on its data portal on 30 September 2026, adding a new monthly data point to one of the most closely watched central bank balance sheets in Europe. The release follows the SNB’s regular statistical publication schedule, which makes balance sheet positions available roughly four weeks after the end of the reporting month, consistent with its broader monthly banking statistics reporting. The dataset allows analysts to track month-by-month changes in the SNB’s assets and liabilities, including its foreign currency holdings and sight deposits.
The publication, listed on the SNB website under statistical publications for September 2026, covers the SNB’s balance sheet positions as of 31 August 2026. It forms part of the bank’s recurring monthly disclosure cycle, in which end-of-month balance sheet items are released through the SNB’s data portal alongside its broader statistical output, including feeds such as the IMF SDDS Plus data portal release. The data portal is the SNB’s central distribution channel for time-series data, offering downloadable series that analysts, economists and journalists use to monitor developments in the Swiss financial system.
The balance sheet of the Swiss National Bank is dominated by its foreign currency positions, which swelled during the years of large-scale currency intervention and remain the single largest driver of the bank’s balance sheet size. Key items that observers track in each monthly release include foreign currency investments, claims from Swiss franc repo transactions, sight deposit account balances of domestic banks, banknotes in circulation, and provisions. Month-to-month movements in these lines provide an indication of how the SNB is managing monetary policy conditions, including whether it is absorbing or providing liquidity to the money market, and can be read alongside series such as the exchange rate indices.
The accessible portion of the 30 September publication consists primarily of the release notice and portal metadata; the underlying data tables are served through the portal interface. As a result, the specific figures contained in the end-August 2026 dataset could not be verified from the summary material available at the time of writing, and no month-on-month or year-on-year comparisons can responsibly be stated here.
Why the SNB’s Balance Sheet Draws Attention
The SNB’s balance sheet is a direct record of past monetary policy action. Its large foreign currency portfolio is the legacy of years in which the central bank bought foreign currencies to cap the franc’s appreciation, and changes in these holdings show whether the bank has been adding to or winding down those positions. A shrinking foreign currency book would suggest continued sales of currency holdings — a policy the SNB has used in recent years to reduce the portfolio — while an expanding one would point in the opposite direction.
For markets, the monthly figures matter because they feed into expectations about Swiss franc liquidity, the trajectory of sight deposits held by domestic banks at the SNB, and ultimately the stance of monetary policy. A larger balance sheet generally signals expansionary liquidity provision, while contraction can accompany policy normalisation. Economists also watch the bank’s provisions and equity positions, since losses on the foreign currency portfolio have in the past translated into negative SNB results — a topic of recurring public and parliamentary debate in Switzerland.
The release also has practical value beyond markets: it is a primary source for journalists, researchers and parliamentary committees assessing the financial consequences of the SNB’s policy history.
The Monthly Publication Cycle Behind the Data
The SNB publishes monetary policy statistics and balance sheet data on a fixed calendar through its data portal, which replaced older distribution formats and provides machine-readable time series. Monthly balance sheet items typically appear around four weeks after the end of the reporting month, with the end-August 2026 dataset released on 30 September 2026 fitting that pattern.
The bank’s balance sheet grew dramatically from the early 2010s onward as the SNB intervened heavily in foreign exchange markets, at times during the 2011–2015 minimum exchange rate period and again during subsequent episodes of franc strength. From mid-2022, the SNB moved to selling foreign currency holdings as it tightened policy, and the balance sheet has been on a broadly declining path since then, though the exact trajectory in any given month can only be read from the published figures. The end-August 2026 release is the latest instalment in that ongoing series, arriving roughly two weeks after the SNB’s quarterly monetary policy assessment in September 2026.
What the Release Notice Does Not Show
The specific figures for end-August 2026 — the total balance sheet size, foreign currency holdings, sight deposits and other line items — are contained in the data tables behind the portal release and were not available in the accessible summary material at the time of writing. It is therefore not yet clear from this source whether the balance sheet expanded or contracted in August 2026, and by how much.
Any month-on-month or year-on-year comparison would need to be drawn directly from the published series. The data itself is not contested — it is an official statistical release — but its contents remain unverified here, and figures cited by third parties should be checked against the SNB portal before being relied upon.
Upcoming SNB Data and Policy Milestones
The next monthly instalment — balance sheet items for end-September 2026 — is expected on the data portal in late October 2026, following the usual four-week lag. Analysts will compare the August and September datasets to gauge the direction of liquidity management following the September 2026 monetary policy assessment.
Readers seeking the actual figures can access the series directly on the SNB’s data portal, which also offers longer historical time series for the balance sheet lines. The SNB’s annual results presentation, typically in early January, will later provide a fuller accounting of the 2026 financial year, including profit and loss effects tied to the foreign currency portfolio.
Key Questions
What exactly did the SNB publish on 30 September 2026?
The SNB published its balance sheet items as of 31 August 2026 through its data portal, as part of its regular monthly statistical reporting cycle.
Why does the SNB balance sheet matter to ordinary readers?
Its size and composition reflect past currency interventions and current liquidity management, influence money-market conditions in Switzerland, and determine the bank’s annual profit or loss — which affects the dividend paid to Swiss cantons and the Confederation.
Are the actual August 2026 figures included here?
No. The data tables reside behind the SNB portal interface, and the accessible release summary did not contain the figures. Any specific numbers should be taken directly from the SNB data portal.
When is the next balance sheet release due?
Figures for end-September 2026 are expected in late October 2026, based on the SNB’s usual publication lag of roughly four weeks.
