The Swiss Franc as a Safe Haven: How the SNB Shapes CHF

The Swiss franc is a safe haven because Switzerland combines low inflation, a long-running current account surplus, large foreign assets and political stability. Investors buy francs when markets panic, which pushes the currency up. The Swiss National Bank then leans against excessive strength using interest rates and, when needed, foreign exchange interventions.

A safe-haven currency is one that tends to hold its value, or rise, when global markets are under stress. Few currencies play that role as consistently as the franc. That reputation is a point of pride in Switzerland and, at the same time, a recurring headache for the country’s exporters and for the central bank that has to manage the consequences.

For anyone looking to trade CHF currency pairs, the franc’s behaviour makes more sense once you see both forces at work: money flowing in when the world is nervous, and a central bank that is openly willing to push back.

Why investors run to the franc

Safe-haven status isn’t declared; it’s earned through behaviour in crisis after crisis. For the franc, it rests on a handful of structural features that change only slowly:

1. A persistent current account surplus. Switzerland has run a current account surplus since the 1980s, as former SNB Chairman Thomas Jordan noted in a 2017 speech. The country earns more from the rest of the world than it spends there, which creates steady underlying demand for francs.
2. Large foreign assets. Decades of surpluses have left Swiss investors, pension funds and insurers with substantial holdings abroad. In times of stress, some of that money comes home, and bringing it home means buying francs.
3. Low and stable inflation. The SNB equates price stability with annual inflation of between 0% and 2%, and Swiss inflation has tended to stay low by international standards. A currency that loses little purchasing power is a natural place to park money.
4. Political stability and neutrality. Switzerland’s institutions, direct democracy and long tradition of neutrality reduce the risk that its assets become caught up in conflicts elsewhere.
5. A deep, trusted financial system. The franc is liquid and widely traded, so large sums can move into it quickly when fear spikes.

None of these features guarantees that the franc will rise in any particular crisis. Together, though, they explain why so much money tends to head in its direction when the headlines turn dark.

The SNB’s toolkit

A strong franc makes Swiss exports more expensive and imported goods cheaper, which can push inflation below the SNB’s target range. When safe-haven demand overshoots, the central bank has several tools to lean against it:

The SNB is unusually open about its willingness to use the currency market. Rather than relying on rates alone, it has repeatedly signalled that it will intervene when it judges the franc to be moving in a way that threatens price stability. That readiness is part of what traders price into CHF every day.

15 January 2015: the day the floor broke

The most famous episode in the franc’s modern history is a lesson in how quickly a central bank commitment can change. In September 2011, with the euro crisis driving money into Switzerland, the SNB announced it would no longer tolerate a EUR/CHF rate below 1.20 and would defend that level with unlimited interventions.

For more than three years, it did. According to the SNB’s own history of the minimum exchange rate, it bought almost CHF 250 billion in foreign currency between September 2011 and January 2015 to hold the line.

Then, at 10:30 on 15 January 2015, the SNB discontinued the floor and cut its deposit rate to −0.75% at the same time. EUR/CHF fell to 0.85 in the immediate aftermath, as the SNB itself records. In its announcement, the central bank said the floor was no longer justified as the international environment had changed.

The shock rippled far beyond Switzerland. Traders who had assumed the floor was permanent were caught with large positions, some brokers faced heavy losses as clients’ accounts went negative, and liquidity vanished for a time. Several lessons from that day still hold:

• A central bank promise is a policy, not a law of nature. It can end, and it may end without warning.
• Crowded positions make shocks worse. When everyone relies on the same assumption, there’s no one left to take the other side.
• Stops aren’t guarantees. In a market that gaps, orders can be filled far from their trigger levels.
• Leverage turns surprises into disasters. A move that would be painful unleveraged can wipe out an account with leverage.

Gaps of that size are rare, but they are the reason careful traders check how their orders behave in fast markets and how negative balances are handled, whether they trade through NumanCap currency and CFD trading or any other provider. It’s a question worth asking before a crisis, not during one.

Where the SNB stands now

At its most recent quarterly assessment on 24 September 2026, the SNB left its policy rate unchanged at 0%. In its introductory remarks at the news conference, the SNB said it remains willing to be active in the foreign exchange market as necessary, and that its conditional inflation forecast remains within the 0% to 2% range it equates with price stability.

The franc’s path in 2026 shows how quickly the backdrop can shift. Early in the year, the franc climbed to its strongest level against the US dollar in over a decade, according to CNBC, as global uncertainty drove safe-haven demand. By September, it had softened against the euro and the dollar, with the gap between Swiss and foreign interest rates widening as other central banks tightened. The same currency can play different roles within a few months.

The next scheduled assessment is due in December. Because rate expectations, intervention signals and the inflation forecast all come together on those four dates each year, they are among the most closely watched events for CHF.

Safe haven doesn’t mean one-way

A common mistake is to treat the franc as a currency that only goes up. In reality, its behaviour depends on the mood of global markets and on what the SNB is doing.

The carry trade deserves a special mention. With Swiss rates at or near zero, the franc is an attractive currency to borrow in. That works well in calm markets, but when fear returns, those trades are unwound quickly, and the rush to buy francs back can amplify the currency’s rise.

Gold and the franc: Switzerland’s two havens

Switzerland is linked to safety in two ways. Alongside its currency, it plays an outsized role in the physical gold market, and the two often attract the same nervous money at the same time.

That connection runs deeper than symbolism. Much of the world’s gold passes through Swiss refineries before reaching vaults, jewellers and central banks. We explain how that came about, and why it matters for global gold flows, in our guide to why Switzerland is the world’s gold refining hub.

Trading CHF: practical points

For traders, the franc’s safe-haven role creates both opportunities and particular risks. A few practical habits help:

• Mark the SNB calendar. Quarterly assessments in March, June, September and December often move CHF, even when the rate decision itself is expected.
• Watch global risk, not just Switzerland. Much of the franc’s movement comes from events elsewhere, from equity sell-offs to geopolitical shocks.
• Respect intervention risk. The SNB can act at any time, and its interventions are not announced in advance.
• Size for gaps. 2015 showed that CHF can move far more than normal volatility suggests.
• Know your pairs. EUR/CHF is heavily influenced by European conditions and SNB policy; USD/CHF also reflects the US dollar’s own safe-haven role, so the two can behave quite differently.

Account structure matters too. Margin requirements, how positions are handled in fast markets and whether negative balance protection applies all vary by provider and by account. Before trading a currency with the franc’s history, take a few minutes to see which account type fits you and read the terms that apply to it.

The view from our desk

The franc’s safe-haven status is real and well earned, but it is not a guarantee of gains or of stability. At NumanCap, our editorial team sees the franc as a currency with two personalities: a refuge that attracts money in a crisis, and a policy instrument that the SNB is willing to steer. Understanding which of the two is in charge on a given day is most of the work.
