This paper studies how IMF lending affects countries' bonds maturity. Debt maturity was claimed to be one of the causes of the crisis of recent years: Too much short-term debt would be the seed of self-fulfilling crises. In turn, one of the goals of the IMF is to prevent crises and to alleviate their effects once they occur. I find that IMF interventions shorten the length of countries' borrowing which is a non desirable, and not analyzed, consequence of IMF lending. Moreover, this finding is consistent with the implications of this Institution's senior status in its lending.
