Swiss Franc's ‘Safe Haven’ Role Affects its Foreign Currency Exchange Rate and Import-Export Trade

By Frances Coppola

The Swiss franc has an unusual role in the global economy, which affects the behavior of its exchange rate and thus influences import-export trade. Because of Switzerland's long history of financial stability, economic strength and political neutrality, the Swiss franc is a favored "safe haven" for investors in times of economic stress. When the global economy is experiencing a downturn, capital flows into Switzerland, driving up its foreign currency exchange rate. Conversely, when the global economy is booming, capital flows out of Switzerland, causing the foreign currency exchange rate to fall.

The Swiss economy, meanwhile, is dependent on external trade, and is particularly sensitive to exchange rate changes in relation to the euro and U.S. dollar. This is important because the Eurozone (particularly Germany) is by far Switzerland's largest trade partner but the U.S. is its second-largest. In 2016, U.S. exports to Switzerland totaled $22.7 billion, while imports totaled $37 billion. The U.S. is one of the top destinations for Swiss investment and is one of the largest foreign investors in Switzerland. Thus, the fortunes of the Swiss economy can be significant for U.S. import-export businesses.


Those fortunes tend to depend upon the Swiss franc's foreign currency exchange rate. A rising foreign currency exchange rate makes Swiss exports less competitive and drives up producer costs, while a falling exchange rate makes its exports more competitive and reduces producer costs. Thus, the franc's "safe haven" role directly affects the performance of the Swiss economy and its import-export trade with the U.S. and Eurozone.


How the Eurozone Crisis Affected the Franc's Foreign Currency Exchange Rate


The last decade has seen a sustained global downturn caused by successive crises – the financial crisis of 2007-8, the sovereign debt crisis of 2009-14 and the commodities price collapse of 2014-15. Global GDP growth has been significantly below its pre-crisis average. Switzerland's two largest trade partners, the U.S. and the Eurozone, were badly affected by, respectively, the financial crisis and the sovereign debt crisis, and their economies have taken a long time to recover. The prolonged Eurozone slump, in particular, has significantly affected the Swiss franc's foreign currency exchange rate and hence the Swiss economy.


Switzerland's real effective exchange rate (REER) started to rise in the fall of 2007,1 now widely recognized as the early days of the financial crisis.2 By the end of August 2011, as the sovereign debt crisis that had started in Greece spread out across the Eurozone,3 the Swiss franc's foreign currency exchange rate had appreciated by 30 percent.4 The Swiss franc's appreciation was a boon for importers, but it caused the prices of Swiss exports to fall and producer costs to rise.5


As Switzerland's terms of trade (the ratio of export prices to import prices) worsened, threatening to trigger a recession in its export-led economy, the central bank (the Swiss National Bank, SNB) imposed a floor on the franc's exchange rate at 1.2 francs to the euro.6 This stopped the franc appreciating, but it was costly for the SNB. Over the next three years, to maintain the foreign currency exchange rate floor, the SNB bought $90 billion of financial assets, exchanging them for newly issued Swiss francs. As a percentage of Switzerland's economy, it was the largest quantitative easing (QE) program in the world.7


In July 2014, the European Central Bank (ECB) slashed its lending rate to 0.15 percent and its deposit rate to minus 0.1 percent. Further rate cuts followed in September 2014.8 And in January 2015, the ECB effectively announced the imminent start of QE.9 Faced with the prospect of very large capital inflows when the ECB's QE commenced, which would make the foreign currency exchange rate floor extremely difficult to maintain, the Swiss central bank abruptly changed its policy. On January 15, 2015, the SNB ended the exchange rate floor and slashed interest rates on deposits to minus 75 percent.10


Economic theory says that investors will sell the currencies of countries with lower interest rates and buy the currencies of countries with higher interest rates. So, a deep rate cut should have prevented the Swiss franc appreciating versus the euro when the foreign currency exchange rate floor was lifted. But because of the franc's "safe haven" status, risk-averse investors, worried about the Eurozone's poor economic performance and the imminent start of the ECB's QE, sold the euro and bought the franc. Instead of falling, the franc's exchange rate soared.11


The SNB's decision did not significantly affect Switzerland's import-export trade. But it did benefit export businesses in the Eurozone. According to John Authers of the Financial Times, the franc's exchange rate floor had been keeping the euro strong against the currencies of all the Eurozone's trading partners. Removing the foreign currency exchange rate floor allowed the euro's trade-weighted exchange rate to fall to a more competitive level, thus helping to generate an export-led recovery.12


What the Franc's Falling Exchange Rate Could Mean for Swiss Interest Rates


Despite the SNB maintaining deeply negative interest rates, and warning that the franc was overvalued,13 the franc's foreign currency exchange rate remained strong until February 2017. Then the Eurozone's recovery encouraged investors to sell the franc and buy the euro. The franc's exchange rate versus the euro started to fall in March 2017,14 followed by the REER in mid-2017.15 Once the ECB started dropping hints that QE could end in 2018, the franc's fall accelerated. In April 2018, the foreign currency exchange rate passed 1.20 to the euro, the floor set by the SNB back in 2011. Some analysts think it will weaken further.16


This raises questions about the SNB's interest rate policy. The purpose of the negative rate was to discourage investors from buying assets denominated in Swiss francs, and thus put downwards pressure on the franc's exchange rate. But now that the foreign currency exchange rate has fallen below its 2011-2014 floor, some analysts are predicting that the SNB may soon start to consider raising interest rates.17


However, the strong franc has taken a considerable toll on the Swiss economy. GDP growth fell from 2.8 percent in the fourth quarter of 2014 to 0.59 percent in the first quarter of 2017,18 while inflation was stubbornly below zero from the end of 2014 through 2017.19 Now that the franc is weakening, GDP growth has improved to nearly 2 percent,20 and inflation has risen to just above zero.21 But raising rates earlier than the ECB might strengthen the franc's foreign currency exchange rate again, which could reverse these gains. The SNB has signaled that it is likely to wait for the ECB to start unwinding QE and raising interest rates before it tightens monetary policy.22



In recent years, the Swiss franc's "safe haven" role has caused its foreign currency exchange rate to rise too high for the Swiss economy, depressing economic growth and inflation. However, as economic growth returns in Switzerland's main trading partners and the franc weakens, the Swiss economy is beginning to recover, raising the prospect of new trading opportunities for import-export businesses.
