Safe-Haven Currencies: Why USD, JPY and CHF Rise in a Crisis
Safe haven currencies explained: why the US dollar, yen and Swiss franc rise in a crisis, when they fail, and how to use them in your risk management.
When markets panic, money does not disappear. It moves, and it tends to move into the same few places every time. If you trade currencies, knowing where it goes, and why, tells you which of your positions are quietly exposed to the next scare.
Quick answer: Safe haven currencies are currencies investors buy when markets panic, mainly the US dollar, Japanese yen and Swiss franc, with gold alongside them. The dollar rises because the world needs dollar cash; the yen and franc rise as carry trades unwind and creditor nations bring money home. They can fail when their own central bank is the problem.
What are safe haven currencies?
A safe haven is an asset that investors buy when they are frightened because they expect it to hold its value while other things fall. Among currencies, three have played that role for decades: the US dollar (USD), the Japanese yen (JPY) and the Swiss franc (CHF). Gold, which belongs to no government, often sits alongside them.
“Safe” is relative. A haven can still fall, sometimes sharply, and holding it is not the same as holding no risk. What makes it a haven is how it tends to behave compared with other assets when fear rises. On a day when share markets drop and higher-yielding currencies such as the Australian dollar slide, the havens usually rise, or at least fall less.
That behaviour has a name, the risk-on / risk-off cycle, and our guide to risk-on vs risk-off shows how to read the market’s mood from stocks, bond yields and other gauges. This article goes one level deeper. It looks at each haven separately, because each one rises for a different reason, and the reasons are what tell you when a haven will work and when it will let you down.
A strong economy is not on those cards. Japan has grown slowly for most of the past thirty years, and the dollar rises in panics that start in the United States. Havens come from plumbing: who owes what, in which currency, and where money flows when it is called home.
Why the US dollar is a safe haven: the world’s emergency cash
The dollar’s haven role rests on one fact. A large share of the world’s borrowing, trade and financial contracts is written in dollars, including by companies and banks outside the United States. The dollar is on one side of almost nine in ten currency trades, according to the Bank for International Settlements, and it makes up well over half of the reserves held by the world’s central banks.
In calm times that is just background. In a crisis it becomes the whole story, because debts in dollars still fall due when markets seize up.
Three features make the dollar the market’s emergency cash.
Liquidity. Liquidity is how easily you can buy or sell large amounts without moving the price. The dollar market is the deepest in the world, so a pension fund that needs to raise billions in an afternoon can do it in dollars.
Dollar debts abroad. A Korean shipbuilder, a Brazilian bank and a Turkish airline may all owe dollars. When their own currencies fall in a panic, those debts become more expensive, and they scramble to buy dollars before they get dearer still.
US Treasuries. The US government bond market is where large investors park money when safety and liquidity matter more than return. To buy Treasuries, foreign investors first have to buy dollars.
There is a paradox here. The United States is the world’s largest net debtor: foreigners own far more US assets than Americans own abroad. So the dollar’s haven status does not come from money flowing home, as it does for the yen and franc. It comes from everyone else needing dollars at the same moment.
That is why the dollar can rise even when the crisis is American. In 2008 the trouble began in US housing and US banks, yet the dollar strengthened against most currencies as the panic spread. In March 2020, the scramble for dollars was so intense that investors sold gold and even US government bonds to raise cash, until the Federal Reserve widened its dollar swap lines with other central banks. The exception is a scare centred on US policy or US assets themselves, when the yen, the franc and gold can do the work instead.
Why the yen is a safe haven: creditors and the carry trade
The yen’s haven role looks stranger than the dollar’s. Japan has had low growth, high public debt and, for most of three decades, interest rates at or near zero. Yet when fear spikes, the yen often rises against almost everything, including the dollar. Two flows explain it, and both run in the same direction.
Japan is a creditor nation. For more than thirty years Japan has been one of the world’s largest net creditors: Japanese households, pension funds, insurers and companies own far more assets abroad than foreigners own in Japan. In a crisis, some of that money comes home. Selling a foreign bond and bringing the proceeds back to Tokyo means selling foreign currency and buying yen. Even the expectation of that flow is enough for traders to buy yen ahead of it.
The yen is a funding currency. Because Japanese rates were so low, the yen became the world’s favourite currency to borrow. In a carry trade, an investor borrows a low-rate currency, sells it, and buys a higher-yielding one to earn the difference. In calm markets this slowly weakens the yen. In a panic, the trades are closed together: the higher-yielding assets are sold and the borrowed yen is bought back. Our guide to the carry trade covers how these positions build up and unwind.
The result is that the yen often outperforms even the dollar in a classic risk-off move, so USD/JPY tends to fall. Crosses that pair a risk-sensitive currency with the yen, such as AUD/JPY, tend to fall hardest of all. A recent example came in August 2024, when a Bank of Japan rate rise and weak US jobs data narrowed the rate gap from both sides. Yen-funded positions were closed in a rush and the yen jumped. Our USD/JPY trading guide covers that episode and the threat of official intervention in detail.
The Swiss franc safe haven and the SNB
The franc shares two of the yen’s features. Switzerland holds large net foreign assets relative to the size of its economy, and Swiss interest rates have often been the lowest in Europe, which made the franc a funding currency too. Add low inflation, low public debt, a long tradition of political neutrality and a large, trusted banking system, and you have a currency that investors, especially European ones, reach for when worried.
The franc’s haven role is most visible against the euro. Because Switzerland sits in the middle of the euro area and trades heavily with it, stress inside Europe tends to show up as a falling EUR/CHF. That makes EUR/CHF a useful gauge of euro-area nerves in the way AUD/JPY is a gauge of global risk appetite. USD/CHF is muddier, because both sides are havens.
The tap-through map below shows the five broad forces on the franc. Compare Risk sentiment, which pushes the franc up in a panic, with Interest rates, where the Swiss National Bank has often leaned the other way.
▲ Higher rates
▼ Lower rates
Higher interest rates attract foreign money seeking better returns, which must be converted into the currency first. Rate expectations are the single biggest driver of major currencies.
The five main drivers of the Swiss franc. In a crisis, risk sentiment pushes the franc up; the Swiss National Bank's low or negative rates and its interventions have often been used to lean against that strength.
What the Swiss National Bank has done about it
A haven currency is wonderful for savers and painful for exporters. When the franc rises too far, Swiss watches, machinery and medicines become more expensive abroad, and imported goods push Swiss inflation towards zero or below. So the Swiss National Bank (SNB) has repeatedly tried to limit haven strength. Its history shows that a central bank can lean against a haven flow, and when it stops leaning, the move can be violent.
2011: the floor. During the euro-area debt crisis, money poured into francs and EUR/CHF fell from above 1.60 before the financial crisis to close to parity by August 2011. On 6 September 2011 the SNB set a minimum exchange rate of 1.20 francs per euro and said it was “prepared to buy foreign currency in unlimited quantities”. For more than three years, EUR/CHF sat just above 1.20.
2015: the floor goes. On 15 January 2015 the SNB scrapped the floor without warning and cut its deposit rate to −0.75%. EUR/CHF collapsed in minutes, briefly trading well below 1.00 before settling near parity. Many stop orders could not be filled anywhere near their level, because there were no buyers on the way down. Some retail traders ended the day owing their brokers money, which is exactly the situation negative balance protection, now required for retail clients in the UK and EU, is designed to prevent. Our guide to slippage explains why stops behave this way in a gap.
2015 to 2022: negative rates and intervention. With the floor gone, the SNB used two other tools: a negative policy rate, which made holding francs less attractive, and frequent purchases of foreign currency. It ended negative rates in 2022 as inflation rose, and has since moved rates up and back down as inflation changed.
The lesson for a trader is simple. On a franc pair, the central bank is a participant with a very large wallet and a clear dislike of a strong currency. The Academy lesson on central banks explains how to read their intentions, and our USD/CHF trading guide applies them to the franc’s main dollar pair.
Gold and the pecking order between havens
Gold is not a currency, but forex platforms quote it as XAU/USD and many traders treat it as a fourth haven. Its appeal is that it has no issuer. A government bond depends on the government; a bank deposit depends on the bank; gold depends on nobody. Central banks hold it in their reserves for the same reason, and they have been heavy buyers in recent years.
Gold tends to shine when the worry is about money itself: high inflation, very low real interest rates, or doubts about a particular government. It can disappoint in a pure dash for cash, when investors sell whatever they can to raise dollars. Our XAU/USD trading guide covers how it behaves day to day.
Which haven wins depends on the kind of crisis. The table below is a deliberately simplified summary of four well-known episodes, scored against risk-sensitive currencies such as the Australian dollar.
Three rules of thumb come out of it.
- A funding panic favours the dollar. When the problem is that everyone needs cash now, the dollar tends to beat even the other havens.
- A slower-burning fear favours the yen, franc and gold. When the worry is about growth, a region or a government, carry trades unwind and creditor money comes home without the same scramble for dollars.
- A haven against a haven is a coin toss. USD/JPY and USD/CHF can go either way in a panic. The cleanest expression of fear is a risk-sensitive currency against a haven, which is why AUD/JPY and EUR/CHF are watched so closely.
When safe haven currencies fail
Every haven rests on a mechanism, and every mechanism can switch off. The clearest recent case is the yen in 2022.
That year inflation surged across the world and the Federal Reserve raised rates faster than at any time in four decades, from near zero in March to a range of 4.25–4.50% by December. The Bank of Japan did the opposite of everyone else. It kept its short-term rate at −0.1% and held ten-year Japanese government bond yields close to zero. The gap between US and Japanese rates widened every month.
The result was a haven running backwards. Stocks and bonds fell together for much of 2022, a textbook risk-off backdrop, yet the yen weakened sharply. USD/JPY climbed from about 115 at the start of the year to above 150 in October. Japan’s Ministry of Finance bought yen in September 2022 for the first time since 1998, and again in October. The carry trade, which normally makes the yen rise in a panic, was doing the opposite: with the rate gap so wide, borrowing yen to buy dollars was too attractive to give up.
The interest rate gap overpowered the haven role, which is why our guide to how interest rates affect currency is the natural companion to this one. The pattern did not end in 2022: USD/JPY went on to trade above 160 in 2024, before the Bank of Japan’s first rate rises in years set off the August unwind described earlier.
Havens can fail in other ways too. A pure dollar scramble, as in March 2020, can drag the yen and gold lower against the dollar for a few weeks. A scare centred on the United States can leave the dollar lagging. And a central bank can refuse to let its currency rise, as the SNB did for years. The questions worth asking about any haven, before you rely on it, are:
- Is the funding mechanism still on? If the haven’s central bank is raising rates while others cut, or the reverse, the carry flows may run the other way.
- Is the country itself part of the problem? A haven cannot shelter you from a crisis about its own economy or politics.
- Is someone leaning against it? Intervention, a floor or negative rates change the odds, and they can be withdrawn without notice.
How to use safe haven currencies in your risk management
You do not need to forecast the next crisis to use any of this. The practical value is in knowing what your open positions are already betting on. The Academy lesson on risk-on and risk-off sorts the currencies into groups; here is how to turn that into risk decisions.
Label every trade by its haven exposure. Long a haven, short a haven, or neither. Long AUD/USD is short a haven. Long USD/JPY is short the yen. Short EUR/CHF is long one. If most of your book is short havens, you are effectively selling insurance.
Recognise the insurance trade. Being short a haven often pays a little every day. Long USD/JPY has tended to earn positive swap while US rates sit well above Japanese ones, and higher-yielding currencies against the franc work the same way (our guide to forex swap shows how it is calculated). Like selling insurance, it collects small premiums in calm markets and pays out in one large lump when the storm arrives. Size such trades for the storm.
Size for the gap, not just the stop. A stop loss limits your loss only if the market trades through it in an orderly way. Haven moves are often the opposite: weekend gaps, interventions, floor removals and carry unwinds where price jumps past your level. USD/JPY has moved more than 300 pips in a single day several times in recent years, during interventions and the August 2024 unwind. The chart below steps through what that means for a single trade.
Illustrative USD/JPY chart, not real prices. A long trade with a 50-pip stop meets a risk-off gap. The stop becomes a market order and fills 300 pips from entry, which is why haven-sensitive trades need a stress test as well as a stop.
Treat related trades as one bet. Several positions that all lose when havens rise are one idea, however different the tickers look. Our guide to currency correlation and the Academy lesson on correlation risk show how to cap the total.

Now try the idea on a realistic Friday afternoon.
What would you do?
It is Friday afternoon. You hold long USD/JPY, earning a positive swap, and long AUD/USD. A large bank reports serious trouble, share markets drop 3% and the yen starts to climb. What do you do before the weekend?
Common mistakes with safe haven currencies
Assuming a haven always rises
The yen fell for most of 2022, and the dollar has lagged in scares centred on the US. Havens rest on mechanisms. Check that the mechanism is still working before you lean on it.
Forgetting that you are short a haven
Long AUD/USD, long USD/JPY and long GBP/CHF all lose when havens are bought. If you only count currencies and not exposure to fear, you can be far more concentrated than you think.
Trusting a stop to cap a haven move
Floors, interventions and weekend shocks produce gaps that jump past stops. Size haven-sensitive trades so that a gap well beyond your stop is survivable.
Fighting a central bank
Selling the franc because “the SNB will step in”, or buying it because “they cannot hold the line”, are guesses about a participant with unlimited currency of its own. Let your plan, not a bet on policy, decide your trades.
Frequently asked questions
What are the main safe haven currencies?
The three traditional safe haven currencies are the US dollar, the Japanese yen and the Swiss franc, with gold often treated as a fourth haven. They tend to rise, or fall less than other currencies, when investors are frightened. Each has a different reason: dollar funding needs for USD, carry trade unwinds and repatriation for JPY and CHF.
Why is the Swiss franc a safe haven?
Switzerland has large net foreign assets, low inflation, low public debt and a long record of political stability. Swiss rates have often been low, so the franc has also been used as a funding currency. In a crisis, money comes home and carry trades are closed, both of which mean buying francs. The Swiss National Bank has often leaned against that strength.
Is the US dollar still a safe haven?
In most global panics, yes. Much of the world's debt and trade is in dollars, so a crisis creates urgent demand for them, and US Treasuries are where large investors park cash. The dollar's haven role is weaker when the scare is about the United States itself; then the yen, franc and gold may do better.
Why did the yen fall in 2022 if it is a safe haven?
Because its main mechanism switched off. The Federal Reserve raised rates rapidly while the Bank of Japan kept them below zero, so the rate gap made the yen attractive to borrow and sell. USD/JPY rose from about 115 to above 150, and Japan intervened to buy yen. The interest rate gap outweighed the haven role.
Is gold a better safe haven than currencies?
Not better, different. Gold has no issuer that can default, so it tends to do well when the worry is inflation, a government or the currency system itself. In a sudden dash for cash it can be sold to raise dollars, as happened briefly in March 2020. Many traders watch gold alongside the three havens rather than instead of them.
