The Czech koruna returned to the weak side of the EUER/CZK 30.00 yesterday. It opened at EUR/CZK 29.86, but the unit lost ground over the whole session to close at 30.03. The most likely reason behind the price action was that investors booked their profits on the better-than-expected January inflation. Nevertheless, investors took profits in the whole region, particularly in Poland. Thus the real cause might be the recent rebound of the US dollar, what sends usually high-yielding currencies lower. As we wrote yesterday, the fact that low inflation opened room for another rate cut might not affect the currency, because it is not very sensitive to the interest rates now. Today the market may rest at EUR/CZK 30.00 zone. Further development depends on the atmosphere in the region. Traders may watch Polish zloty, whether it digest the current political turmoil. However we put the risk for the koruna strengthen again.
