US 30-year Treasury yields have remained elevated at levels not seen since 2006, driven by persistent budget deficits, heavy corporate issuance supply, and uncertainty ahead of the next FOMC decision. The sustained duration of this yield elevation, not merely a spike, is what distinguishes the current episode and keeps institutional investors cautious about adding long-dated exposure. September typically brings additional Treasury supply pressure, which may extend the selloff.
For Armada's traditional repo desk, prolonged elevated long-end yields mean Treasury collateral posted in repo agreements is carrying lower mark-to-market values for longer. This increases the probability of variation margin calls and requires vigilance on haircut adequacy. Primary dealer counterparties managing inventory in this environment may also tighten terms on term repo backed by long-duration Treasuries.
