The action by the Swiss National Bank yesterday rippled through FX markets fuelling sharp moves across major currencies. In case you missed it the SNB introduced a currency floor in EUR/CHF at 1.20 and committed itself to buy FX in unlimited amounts. The last time the SNB did something similar was in 1978 when a ceiling was set against the Deutsche Mark. The sharp initial reaction to the news saw EUR/CHF jump by around 8.5% largely as a result of the shock from the announcement.
The SNB will not need to worry about the inflationary implications of pumping CHF into the market while it is clear that the currency is highly overvalued, supporting their cause. However, the real test will be evident over coming days and weeks in the commitment to hold the 1.20 level at a time when the situation in the eurozone periphery continues to deteriorate and demand for CHF remains strong. The risk is that the SNB may have simply set up a target for markets to attack. One other implication of the SNB’s move is that it could be a trigger for an intensification of ‘currency wars’.
The onus is now on the Japanese authorities to act more aggressively especially if safe haven flows focus increasingly on the JPY and less on the CHF given the new EUR/CHF floor. So far FX interventions have clearly not worked as was the case in Switzerland and Japan’s new Prime Minister is likely to want to prove his credentials. Japan has had a tendency to underwhelm with regard to JPY measures in the past and unless there is a major announcement today USD/JPY is likely to move lower again below 77.00.
Scandinavian currencies are also set to be beneficiaries of the SNB’s decision. EUR/SEK has come under increasing downside pressure over recent weeks even as risk aversion has intensified and it appears that safe haven flows out of Europe are now targeting Scandinavian currencies. As the CHF is now less attractive in this respect, the SEK as well as NOK will find themselves under further upside pressure over coming days and weeks. Both NOK and SEK versus EUR and USD have had insignificant correlations with risk over recent months, highlighting their appeal as anti-EUR currencies.
