For the past 15 years, trust preferred securities (TruPS) have constituted a significant percentage of the capital of many financial institutions, mostly bank holding companies.Their ubiquity, both as a source of capital and as a common investment for banks, made them a quiet constant for many financial institutions. Even in the chaos of the Great Recession, standard TruPS terms allowed for the deferral of interest payments for up to five years, easing institutions’ cash-flow burdens during those volatile times.
