The Fund’s debt limits policy has been in place since the 1960s. From the policy’s inception, concessional flows have been excluded from debt limits under the presumption that such financing was critical for LICs and posed only limited risks to debt sustainability. Over time, the exclusion of concessional flows has led to a bifurcation in the policy, with one branch focusing on members to whom concessional financing is normally available, and the other on those to whom it is not—a distinction which in practical terms has involved differentiating between LICs and non-LICs.
