Summary
A sharp sell-off in European government bonds in October has renewed scrutiny of hedge funds' growing role in a systemically important market, according to Reuters. French 10-year yields rose to 24-year highs, with daily yield increases of more than 10 basis points and a nearly 25 bp two-day jump in the premium investors demand to hold French debt over German bonds, the largest such move since the euro zone debt crisis. No obvious trigger preceded the moves, which some investors attributed partly to hedge funds rapidly unwinding trades.
The European Central Bank estimates hedge funds account for more than half of trading in the roughly $13 trillion European government bond market, up from 30% in 2020. The International Monetary Fund says hedge fund exposure to sovereign bonds has more than doubled since 2022, and that hedge funds, which oversee over $40 trillion including leverage and derivatives exposure, can amplify price dislocations and liquidity strains during stress. Pictet Wealth Management's Lauréline Renaud-Chatelain said the hedge fund community's growth has brought more volatility to the bond market. Fidelity International's Marion Le Morhedec said hedge funds can 'completely wipe out the market' when crowded, debt-funded positions are exited en masse, and attributed '100%' of early October's low liquidity to this dynamic.
Others urged caution. Bruno Schneller of Erlen Capital Management cautioned against attributing the volatility solely to hedge funds, citing fundamental drivers in France, including political uncertainty ahead of the 2027 presidential election that could hinder deficit reduction. The Alternative Investment Management Association's Jiri Krol described hedge funds as one of bond markets' most important sources of liquidity and warned against 'hasty, broadbrush pronouncements.' Hedge funds have taken a larger share of government bond markets as central banks shrink balance sheets, pension demand falls and bank regulation limits bond holdings. JPMorgan CFO Jeremy Barnum described hedge fund leverage as 'in the category of known unknowns.'
Liquidity and collateral channels are drawing attention. French debt makes up about €100 billion ($112 billion) of the €250 billion of euro zone government bonds pledged for repo borrowing, according to Bank of France data. The Bank of England estimates £85 billion ($113 billion) of the £200 billion net gilt repo borrowing comes from hedge funds. Pictet said French bond liquidity in early October was the worst since 2008. A separate IMF report said markets have managed recent stress well, and fund managers Reuters spoke to said volatility had not yet affected their strategies and at times created opportunities, with Standard Life's Michela Bariletti adding to French bonds during the sell-off.
