The US dollar rallied sharply in the week ending May 15, on pace for its strongest weekly gain since March, after inflation data came in hotter than expected and rekindled market expectations for a Fed rate hike within the next twelve months. Fed funds futures shifted to price a meaningful probability of at least one additional hike, a significant reversal from the cut-dominant pricing that had prevailed through early 2026.
For Armada's traditional repo desk, higher-for-longer or hike-scenario rate paths create mark-to-market pressure on longer-duration Treasury and agency collateral, potentially triggering margin calls or collateral substitution requests from hedge fund and asset manager counterparties. SOFR fixings may also drift higher, affecting floating-rate repo pricing. Primary dealer inventory costs rise in this environment, which can reduce their appetite as repo counterparties.
