Poland's subsequent involvement with IMF lending facilities can be separated into two periods: emergence from communism and Stand-By Arrangements (SBA) from 1990 to 1996, followed by Flexible Credit Line (FCL) arrangements from 2009 to 2017. The first years mark Poland's transition from a planned to a market economy, aided by the IMF, followed by Poland's growth through the global financial crisis and Euro-zone crisis. In 2018, Poland purchased a large number of gold reserves, the largest purchase since 1983.
