London Macro Funds Exit Nearly 100 European Rates Positions as French OAT Repo Carry Trade Unwinds

The carry trade consisted of purchasing OATs, financing them via repo using the same bonds as collateral, and capturing the spread between bond yield and financing cost. Leverage amplified modest basis-point gains into seven-figure payouts until French political instability and October budget developments reversed the flows. Data from Eurex and dealer reports showed heavy positioning that turned into simultaneous exits once stop-losses triggered. Fidelity International estimated hedge-fund flows accounted for roughly half the recent OAT-Bund spread widening.

The same cohort had executed an identical structure in prior cycles, exiting only when collateral value itself became the constraint. Primary records from liquidity providers and asset managers confirm repeated exposure to French and Italian EGBs without material duration or credit hedging. This pattern reveals incentive misalignment between short-term carry compensation and longer-term sovereign risk that materializes during fiscal stress.

Attention now shifts to Italy as the next potential pressure point once deleveraging exhausts French positions. Central-bank data and swap spreads indicate limited official absorption capacity if Italian BTPs follow the same widening path. Funds have already reduced risk across EGB books, with no documented re-entry signals.

The episode demonstrates how crowded repo-financed sovereign trades transmit fiscal shocks directly into personnel and capital allocation decisions at multi-manager platforms.
