The Czech central bank has boosted its foreign exchange reserves 14% by printing new korunas to buy foreign currency, as the institution does its part to help the weak domestic economy boost exports and fuel currently-weak domestic inflation. The central bank Monday said it used roughly CZK 200 billion in newly-issued currency in its foreign exchange intervention earlier this month. The bank reiterated both its new CZK 27 per euro exchange-rate target and its ability to sustain that rate in future.
