The US Dollar / Zloty is the most popular pair to trade the Polish currency. Zloty is the Polish word for golden. The Polish economy was the only EU country to avoid a recession in the 2008-2009 financial crisis. Exports provided about 23% of GDP in 2012, and large amounts of trading with the Euro-zone and the UK makes Poland susceptible to influences from those economies.
