Do you know...
that purity is a number expressing the weight content of a precious metal in an object (bar, coin, jewel, etc.) and is usually indicated in thousandths (for example, 750/1,000 indicates an alloy with 75% precious metal content and 999.9/1,000 an alloy with 99.99% precious metal content)? However, purity can also be expressed in other, older or regional units. The most important of these is the carat, which is still used in jewellery (not to be confused with the carat, e.g. the metric carat, as a unit of mass used for gemstones and pearls). An object of theoretically pure content is designated as having 24 carats. Gold of 750/1,000 purity is therefore 18-carat gold, for example. The carat is not a practical unit for gold bars and coins, as it is not sufficiently precise (although a non-whole number, or the gran, which is one-twelfth of a carat, can be used) and the alloy purities used in jewellery do not always match those used for coins.
At its extraordinary monetary policy meeting on 6 April 2017, the Bank Board of the Czech National Bank decided to discontinue the use of the exchange rate as an additional instrument for easing the monetary conditions. By taking this step, the CNB returned to the conventional monetary policy regime, in which interest rates are the main instrument. The koruna exchange rate may thus fluctuate in either direction depending on demand and supply. However, the CNB stands ready to use its instruments to mitigate potential excessive exchange rate fluctuations.
