Amounting to approximately 67% of total debt on average in the OECD, “financial debt” (loans, debt securities and currency and deposits), as defined by the debt regulations set forth in the EU’s Maastricht Protocol, represents the largest share of subnational government debt ( 5.24). In the OECD, debt securities represent the largest share of subnational debt (44% of total debt and 66% of financial debt) while loans amounted to 23% of total subnational debt and 44% of financial debt. This is explained by the weight of state government debt in federal countries, which comprises a high proportion of bonds (the United States, Canada and Germany). Debt securities is also widespread at the local level in some unitary countries (New Zealand, Japan, Norway, Korea, Iceland and Sweden), but, in the majority of unitary countries, issuing local bonds remains limited, or non-existent. As a result, loans are the most widespread form of external funding in unitary countries (58% of total local debt and 69% of financial debt).
