Treasury yields spiked sharply on September 24, driven by a confluence of factors including fiscal concerns, hawkish Fed signals, and weak auction demand. The move was broad across the curve, with longer-dated yields seeing the most pressure, raising debt servicing costs for the federal government and triggering mark-to-market losses across fixed income portfolios held by leveraged investors.
For Armada's traditional repo desk, elevated and volatile yields directly affect the collateral quality and mark-to-market stability of Treasuries pledged in MRA/GMRA agreements. Hedge fund and asset manager counterparties facing duration losses may face margin calls or reduce repo borrowing capacity, increasing rollover and counterparty risk mid-quarter.
