The Polish złoty has rose to its highest level in the first quarter of 2012, having strengthened by 10.5 percent against US dollar during the last three months. Poland’s złoty has also beaten Europe’s common currency by 7.3 percent. This made it the strongest of all currencies to invest in, and the second overall investment choice, following platinum and silver. Asian currencies have been the weakest in recent months, especially Sri Lanka’s rupee, the Iranian rial and the Japanese yen.
