Key Takeaways
- • Arini Capital Management's flagship fund has fallen 16 percent year-to-date through October 2026, with August losses of approximately 1 percent following an 8 percent decline in July, driven primarily by soured European distressed credit positions.
- • The $22 billion London-based hedge fund, founded in 2021 by former Credit Suisse trader Hamza Lemssouguer, has suffered significant losses in high-conviction bets on struggling corporate debt, including positions in Aston Martin and Altice International.
- • Altice International bonds became the fund's largest single-name loss driver in July after Franco-Israeli billionaire Patrick Drahi's actions shifted valuable assets out of collateral pools, triggering disputes between senior bondholders including Arini and the company over restructuring terms.
- • The fund's deterioration marks a sharp reversal from consecutive years of strong returns—27 percent in 2023, 21 percent in 2024, and 10 percent in 2025—as two of Arini's top traders have departed during the period of losses.
Summary
Arini Capital Management, a rapidly expanding European credit-focused hedge fund managing $22 billion, has experienced significant losses in 2026 after years of outsized returns. The fund's flagship strategy declined more than 8 percent year-to-date, with concentrated losses in July and August driven by deteriorating positions in distressed European corporate debt. Specific holdings that suffered include bonds issued by luxury automotive company Aston Martin and telecommunications assets controlled by Franco-Israeli billionaire Patrick Drahi through his Altice International entity.
Founded in 2021 by Hamza Lemssouguer, a 35-year-old former high-yield credit trader at Credit Suisse, Arini quickly established itself as one of Europe's fastest-growing hedge funds through a contrarian strategy employing leverage to take large concentrated bets on struggling company debt. The fund's master fund produced gains of 27 percent in 2023, 21 percent in 2024, and 10 percent in 2025, establishing a track record of profitable risk-taking. This performance reversal signals challenges with the fund's thesis and execution during a period when market conditions for distressed credit have shifted.
The Altice International position exemplified the fund's losses. After Drahi relocated the group's most valuable assets outside the collateral pool pledged to creditors in late 2025, Altice's bond values declined sharply. Arini, positioning itself among senior creditors, joined other holders in negotiations and disputes with the company over restructuring terms. By July 2026, Arini and other creditor groups, including Silver Point Capital, began pushing for preferential payouts in any restructuring as compensation for their litigation exposure. However, the deterioration of the position before any favorable resolution materially impacted monthly returns.
The fund's difficulties have occurred amid organizational stress, with two of Arini's top traders departing during the period of losses. These exits, combined with negative performance, underscore the operational pressures facing the fund as investor scrutiny intensifies over strategy execution and concentrated risk exposure.
