Capital Structure Subordination

Capital structure subordination is the legal and structural mechanism that ranks claims on an entity's assets in a specific order of priority. In the derivative space, this refers to how different tranches of a structured product are ranked regarding their claim on the cash flows generated by the underlying assets.

Subordinated debt, or junior tranches, must wait until all senior claims are satisfied before they receive payment. This creates a clear risk-reward hierarchy where the riskier, subordinated tranches are compensated with higher interest rates.

This concept is fundamental to the stability of financial systems, as it ensures that losses are absorbed by those who have been compensated for that risk. Understanding the specific subordination rules of a protocol or product is essential for assessing the likelihood of capital recovery in a default scenario.
