The Swiss franc, one of the more closely observed currencies in Poland, has risen in price compared to the zloty by about 2 percent over the past two weeks. The franc rate rose above PLN 3.81, reaching the level we recently observed at the beginning of April this year. Unfortunately, the franc may soon be even more expensive. Not only the Polish zloty but also the US dollar or the euro are losing to the franc. In two weeks, the franc strengthened against the euro by about 1.5 percent, and against the dollar by about 1.6 percent.
