Swiss Franc Sinks as Carry Trade and Gold Turn Toxic

Since the Iran shock at the end of February 2026, Swiss Franc weakness has pushed CHF into the ranks of the worst-performing global currencies, alongside SEK, even though the franc briefly caught a risk-off bid in early March.

That is the uncomfortable signal in TD Securities’ view: CHF’s safe-haven label hasn’t disappeared, but it isn’t enough when investors can earn more elsewhere and Gold is moving against the franc. TD strategists argue that the franc’s slide reflects both low-yield carry pressure and sensitivity to bullion prices, according to FXStreet.

XOOMAR analysis: investors shouldn’t treat CHF as an automatic crisis winner in this cycle. The franc still has defensive traits, but TD’s framework says the trade now depends on three moving parts: Swiss National Bank policy, global rate paths, and whether Gold keeps falling.

“Since the Iran shock at the end of February 2026, CHF has become one of the worst-performing global currencies along with SEK. Risk-off sentiment only supported CHF briefly in the first half of March, before a downtrend ensued.”

Since February 2026, Swiss Franc weakness has outlasted the haven bid

The headline move is not just that CHF weakened. It is that Swiss Franc weakness persisted after a geopolitical shock that might normally support the currency.

TD Securities says the risk-off bid lasted only briefly in the first half of March. After that, a downtrend took over. That matters because it separates the initial haven reflex from the sustained FX trade.

The franc’s old playbook is simple: stress rises, investors buy CHF. TD’s point is that this playbook is incomplete in 2026. If the franc pays too little and Gold is falling, CHF can lose even while the geopolitical backdrop remains unsettled.

The market signal is blunt. CHF bears are awake again, but TD does not attribute the move to carry alone. The strategists explicitly add Gold to the explanation.

“CHF has been one of the worst-performing global currencies since the Iran shock in 2026. While CHF bears have been awakened with FX market participants largely attributing CHF weakness to carry, we find falling gold price also matters.”

The carry penalty matters because SNB policy is expected to sit still

CHF has long been a low-yielding currency. That makes it a natural funding candidate when investors focus on rate differentials. But TD is careful here: low yield does not always mean automatic CHF weakness.

The useful comparison is 2022. TD notes that during the last global rate hiking cycle, rate differentials widened against CHF, yet the franc broadly rallied. The driver then was falling SNB sight deposits.

That detail matters because sight deposits have shown only muted change in 2026, according to TD. With that policy channel quieter, macro variables have had more room to drive EUR/CHF.

TD’s base policy assumption is also important. The firm expects the SNB to keep the policy rate on hold for the foreseeable future. If Switzerland sits still while global central bank paths shift, CHF crosses become more exposed to decisions made outside Zurich.

In TD’s words:

“With the SNB likely to keep the policy rate on hold in the foreseeable future, rate paths for global central banks will matter more for CHF-crosses.”

XOOMAR analysis: that is the core of the carry problem. CHF is not being punished only because it yields little. It is being punished because the domestic policy impulse looks muted, leaving the currency to trade off external rates and Gold.

The hard numbers TD gives: $3,900/oz Gold and EUR/CHF near 0.93

The source does not provide a full spot-performance table for EUR/CHF, USD/CHF, or trade-weighted CHF since the Iran shock. It also does not publish rolling 30-day or 60-day correlations between CHF pairs and Gold. Those would be useful, but they are not in the available material.

The numbers TD does give are still enough to frame the trade.

TD’s most actionable condition concerns the European Central Bank. The strategists say the EUR/CHF rally could end if the ECB pauses rate hikes after September. In that scenario, the EU-Switzerland rate differential would likely peak.

That would leave Gold doing more of the work. TD’s view is explicit: if ECB policy stops adding pressure through the rate channel, further Gold weakness would be needed for CHF to stay weak.

Gold now sits inside the CHF trade, not beside it

TD does not claim Gold has fully replaced CHF as a crisis hedge. The narrower claim is more useful: falling Gold prices matter for the franc’s weakness.

XOOMAR analysis: that means traders should treat Gold as part of the CHF setup, not as a separate macro chart. If Gold sells off while CHF offers poor carry, the franc has fewer supports. If Gold stabilizes or rebounds, one leg of the bearish CHF case weakens.

The mechanism is not identical. CHF is an FX position tied to rate paths, central bank expectations, and cross-currency funding logic. Gold has its own opportunity cost and price dynamics. TD’s point is that the two are connected enough for bullion to influence CHF crosses in this phase.

This is also where the forecast becomes self-limiting. TD sees Gold falling to $3,900/oz near term, but then recovering into a new uptrend. That is why the firm does not project an open-ended CHF slide.

A 2022 reminder: rate gaps alone did not always sink CHF

The strongest part of TD’s argument is its refusal to reduce everything to carry. The strategists point back to 2022, when global rate differentials moved against CHF but the franc still rallied as SNB sight deposits fell.

That history matters because it stops investors from making a lazy conclusion: low-yield currency equals short. CHF can rally against rate logic when domestic policy flows or balance-sheet signals dominate.

In 2026, TD says sight deposits have shown muted change. That shifts the market’s attention back to macro variables, especially global rate paths and commodities.

XOOMAR analysis: the franc’s safe-haven identity has always been conditional. Policy signals can amplify it, suppress it, or redirect it. In the current setup, the SNB is expected to sit still, so the currency is being pushed around by forces outside Switzerland.

For CHF-focused readers, XOOMAR’s separate snapshot Swiss Franc Bleeds Eight Days as US Dollar Takes Charge tracks another angle of the same broader question: how durable CHF weakness can be when external drivers dominate.

Into year-end 2026, CHF shorts need Gold to keep falling

TD’s forecast lands in the middle rather than at an extreme. The firm sees limited scope for a prolonged global rate hiking cycle and only modest Gold downside. That leads to a forecast of EUR/CHF staying around 0.93 into year-end 2026.

That is not a screaming bearish call on CHF. It is a conditional one.

For macro FX traders: CHF shorts can still work if carry remains dominant and Gold keeps slipping. But the trade becomes more fragile if ECB rate expectations peak and bullion stabilizes.

For Swiss-linked hedgers: the practical lesson is to stop assuming CHF will behave as a clean haven during every geopolitical shock. TD’s framework suggests hedging decisions need to account for Gold and global rate paths, not only risk sentiment.

For central bank watchers: the SNB staying on hold leaves CHF more exposed to other central banks. If the ECB pauses after one more hike in September, TD thinks the rate-differential tailwind for EUR/CHF could peak.

The next evidence to watch is precise. A continued Gold selloff toward TD’s $3,900/oz near-term view would support the weak-CHF thesis. A Gold recovery, an ECB pause after September, or any renewed change in SNB sight deposits would weaken it.

That is the real message beneath the headline: Swiss Franc weakness is not random, but it is also not guaranteed to extend. It needs carry pressure and Gold weakness to keep moving in the same direction.

The Bottom Line

• CHF is no longer behaving like an automatic safe-haven winner after geopolitical shocks.
• Low-yield carry pressure is making the franc less attractive versus higher-yielding currencies.
• Gold trends and central bank rate paths are now key variables for CHF direction.
