USD/CHF and the Swiss Franc

USD/CHF, informally the Swissy, is one of the seven major currency pairs and one of the two classical “safe haven” pairs in FX (the other being USD/JPY). It accounts for roughly 3-4 percent of daily FX turnover in the latest BIS Triennial Survey. The Swiss franc’s specific character, issued by a country with a stable central bank, deep capital markets, low inflation, and a long history of political neutrality, makes it a specific kind of currency: one that markets buy during times of stress and sell during times of confidence.

This article walks the pair: the quote convention, the Swiss economy’s specific structure, the Swiss National Bank’s inflation-targeting regime, why CHF trades as a safe haven, the 2015 EUR/CHF peg-break event, and the practical pattern for reading USD/CHF.

The quote

USD/CHF is the US dollar against the Swiss franc. USD is base; CHF is quote. USD/CHF = 0.8500 reads: one US dollar is worth 0.85 Swiss francs. The base-currency arrangement matches USD/JPY and USD/CAD but is the reverse of EUR/USD, GBP/USD, and AUD/USD. When USD/CHF rises, the dollar is strengthening against the franc; the franc is weakening.

Pip conventions match European majors: quoted to four decimal places, with the pip at the fourth decimal. A move from 0.8500 to 0.8501 is one pip. Pip value is CHF 10 per standard lot, converted at the exchange rate to approximately $11.76 per pip per standard lot at a 0.85 rate. Pip value in USD changes slightly as the exchange rate moves; the platform calculates it.

The pair’s trading nickname is “Swissy”. The related EUR/CHF is called “Euro-Swiss” or just “the Swiss cross.”

The Swiss economy in one paragraph

Switzerland is a small (approximately 9 million population), wealthy, export-oriented economy with two distinctive features: (1) it is home to some of the world’s largest banks and the largest concentration of private wealth per capita anywhere globally, and (2) it has maintained political neutrality across two world wars and the Cold War, giving the franc a long-standing reputation as a store of value during crises. The Swiss National Bank is one of the more sophisticated modern central banks, with a legal mandate to maintain price stability while giving due consideration to economic developments, a specific formulation that permits activist policy including massive FX interventions and negative-rate experiments.

Why the franc is a safe haven

Three specific factors give CHF its safe-haven character:

1. Political neutrality. Switzerland does not participate in military alliances, does not take sides in major geopolitical conflicts, and has maintained this posture consistently for centuries. During wars, coups, or major geopolitical shocks, capital seeking a politically-neutral destination flows to Switzerland.

2. Deep and sophisticated capital markets. Zurich and Geneva host approximately $3-4 trillion in private wealth management. The infrastructure exists to absorb large capital flows quickly. Contrast with small safe-haven candidates (Singapore, various Nordic economies) that don’t have the same depth.

3. Low and stable inflation. Switzerland has structurally lower inflation than the eurozone or US, driven by strong central-bank credibility, wage discipline, and the currency’s own strength dampening imported inflation. Low inflation means the franc preserves purchasing power better than most currencies in the long run.

These three factors together mean that during risk-off episodes, capital flows into CHF. USD/CHF drops (dollar weakens against franc), often meaningfully. The typical safe-haven response for USD/CHF during a global risk-off event is a 1-3 percent drop over 1-3 sessions.

The Swiss National Bank (SNB)

The SNB sets Swiss monetary policy. The SNB policy rate (the interest rate on sight deposits) is the equivalent of the US fed-funds rate. SNB meetings are held quarterly (four times per year), which is fewer than most major central banks. Each meeting produces a rate decision at 09:30 CET (03:30 ET), followed by a press conference at 10:00 CET.

The SNB has been more willing than most modern central banks to use unconventional tools:

• Negative interest rates. SNB was the first major central bank to introduce negative policy rates (December 2014), cutting to -0.75 percent to counter franc strength during the eurozone crisis. It maintained negative rates through 2022.
• Massive FX intervention. SNB’s balance sheet is approximately 100 percent of Swiss GDP, one of the largest of any major central bank, driven by decades of FX interventions to prevent excessive franc strength.
• Explicit currency ceiling (2011-2015). SNB pegged EUR/CHF at 1.20 as a maximum, requiring continuous CHF-selling to defend the peg. The peg was abandoned in January 2015 in the most consequential single-day FX event of the modern era (see below).

The January 2015 peg break

On January 15, 2015, the SNB unexpectedly announced the removal of the 1.20 EUR/CHF floor with immediate effect. The response was one of the largest single-currency moves in modern FX history:

• EUR/CHF fell from 1.20 to 0.85 within minutes (a 30 percent move), then partially recovered to close around 1.00.
• USD/CHF fell from about 1.02 to 0.74 in the same window.
• Multiple retail FX brokers went insolvent because the move was so fast that stop-loss orders could not be filled at expected prices; brokers took losses on client accounts that exceeded their capital.

The event demonstrated three important lessons still relevant today:

• Central bank commitments are not permanent. The SNB had defended the peg for over three years and consistently characterized it as unshakeable. It broke the peg with a 30-minute pre-announcement warning.
• Currency pegs create asymmetric tail risk. A peg that has held for years accumulates positioning that assumes it will continue. When the peg breaks, that positioning unwinds all at once.
• Retail leverage is dangerous during rare events. Traders who held highly-leveraged CHF positions saw account equity wiped out in minutes.

The 2015 peg break remains the reference event for CHF tail risk. Traders who trade Swiss franc pairs need to understand it.

What drives USD/CHF today

With the peg gone and negative rates ended, USD/CHF today trades on more conventional drivers:

US-Swiss yield differential. SNB policy rate versus Fed policy rate. When the differential widens in favor of dollars, USD/CHF tends to rise. The differential has been unusually wide in 2024-2026 (Fed 3-4 percent vs SNB 0-1 percent), keeping USD/CHF elevated.

Global risk regime. Safe-haven episodes push CHF stronger, USD/CHF lower. Risk-on episodes push CHF weaker, USD/CHF higher. The correlation between USD/CHF and equity risk sentiment (S&P 500) is typically positive around +0.3 to +0.5.

DXY overlay. The Swiss franc is 3.6 percent of the DXY basket, a smaller weight than the euro (57 percent), yen (13.6 percent), or GBP (12 percent). Broad dollar moves register in USD/CHF but less than in the more-weighted pairs.

SNB intervention/commentary. The SNB has continued periodic FX operations to prevent excessive franc strength, particularly during eurozone-related stress. Its commentary characterizing the franc as “highly valued” or “significantly overvalued” is a specific verbal signal to markets.

Sessions and time of day

USD/CHF is primarily a European-session pair. Zurich is the home market. The specific liquidity windows:

• London session (08:00-16:00 GMT). Deepest liquidity. SNB rate decisions publish 07:30 GMT (during the pre-London warmup). See Forex Trading Sessions.
• London-New York overlap (13:00-16:00 GMT). Peak activity.
• Asian session. Relatively quiet for CHF; spreads wider.

Correlations

USD/CHF’s correlation web:

• Strongly negative with EUR/USD. Because EUR/CHF has been relatively stable through most of the post-peg era, USD/CHF often mirrors EUR/USD closely (as USD/EUR × EUR/CHF ≈ USD/CHF, and EUR/CHF holds). Correlation is typically -0.7 to -0.9.
• Negative with equity risk sentiment during crises. Safe-haven bid strengthens CHF.
• Positive with USD/JPY on yield-differential days. Both are USD-base pairs with rate-differential logic.
• Variable with gold. Gold and CHF are both safe-haven assets but respond to different specific drivers. The correlation between them is typically positive but weak (0.2-0.4).

The honest tradability note

USD/CHF is a liquid pair with tight spreads (typically 1.5-3 pips on a good broker). Realistic expectations:

• Tight daily ranges are the norm. The pair typically moves 40-70 pips per day, materially less than GBP/USD (100-150 pips) or USD/JPY (80-150 pips).
• Safe-haven episodes produce sharp moves. During specific stress events, the pair can move 100-200 pips in hours. Positioning size should account for this asymmetry.
• Tail risk is real and historically documented. The 2015 peg break is not repeatable in the same form (no peg exists today), but the SNB has shown willingness to take unconventional action that can produce sharp moves.
• Correlations to EUR/USD reduce the diversification benefit of holding both. Long USD/CHF and short EUR/USD is essentially the same trade; see Currency Correlation and Hidden Risk.

The takeaway

USD/CHF is the US dollar against the Swiss franc, one of the two classical safe-haven pairs. It is driven by US-Swiss yield differentials, global risk regime, and periodic SNB action. The Swiss franc’s safe-haven status comes from Swiss political neutrality, deep capital markets, and low structural inflation. The January 2015 EUR/CHF peg break remains the reference event for CHF tail risk. Retail traders should size positions with awareness of both the pair’s tight normal ranges and the potential for sharp moves during stress episodes.
