The National Bank of Poland reports non-performing loans in two ways, as zloty volume (Mil. PLN) and as percent of loans outstanding (%). The two series run from December 1996 to February 2010.  Because they are new to Data Buffet (to provide historical context) but already terminated by the source, we have marked them as "discontinued."  There is an active dataset starting at 2005 (see related article).

The series reside in the historical catalog (Poland » Banking » [DISCONTINUED] Non-performing loans) and are:

• MBLANPNFCP_10UM.IPOL = [DISCONTINUED] (Mil. PLN)
• MB%ANPNFCPUM.IPOL = [DISCONTINUED] (%)

Because catalog locations are subject to change, the upper-right search box on DataBuffet.com provides a "find in catalog" mode that accepts a mnemonic.
