Global leverage chain hits $400 billion as Goldman warns of systemic risk

Financing costs for US equity derivatives surged to their highest levels since late 2024, with the S&P 500 total return swap rate reaching the federal funds rate plus 127.5 basis points, Goldman Sachs data shows.

"The leverage has become one of the core themes facing investors, with margin debt elevated and borrowing continuing to expand across every link of the shadow banking system," said Andy Kent, a broker at Kyte.

Retail leveraged and inverse ETFs have swelled to nearly $200 billion in assets under management, corresponding to roughly $400 billion in net notional exposure. The surge in demand for leveraged exposure to semiconductor names — including SK Hynix, Samsung Electronics and Taiwan Semiconductor Manufacturing Co. — has pushed dealer capacity to its limit, with banks increasingly relying on total return swaps to meet client demand. The gap between implied financing rates for S&P 500 futures and Russell 2000 futures widened to a multi-year high, reflecting a stark divergence in leverage demand between large-cap technology and small-cap stocks.

The risk, according to Goldman, is that if any single counterparty along the leverage chain faces a margin call or funding squeeze, the entire structure could reverse violently, triggering a cascade of forced selling across global equities. With the S&P 500 having rallied roughly 15% in the second quarter and the tech-heavy Nasdaq surging 21%, much of those gains rest on borrowed money.

Asia's Leverage Feedback Loop

Goldman's analysis identified South Korea's KOSPI index as a particularly acute example, describing it as having "evolved into a massive self-reinforcing feedback loop" driven by the continuous stacking of leverage. Korean regulators have attempted to tighten controls on total return swaps, but the measures have had limited effect in curbing the expansion of market leverage. Retail demand through leveraged ETFs has combined with institutional TRS positions to push dealer financing capacity to its boundary in the region.

Hedging Picks Up as Financing Costs Bite

As financing costs climb and technology valuations stretch, some investors have begun hedging. Banks are observing significant client flows on both sides of major macro themes. Raphael Cyna, head of global equity derivatives structuring at Bank of America, noted that clients initially positioned for stagflation — equities down, rates up — and have since rotated into recession hedges betting on equities falling alongside lower rates. JPMorgan strategist Bram Kaplan has advised clients to buy S&P 500 call options linked to rising rates, seeking to exploit the divergence between equity and bond correlations that have fallen to multi-year lows.

Goldman's futures desk warned that financing costs could rise further as the quarter-end approaches, echoing a similar pattern observed in May. The deeper concern: when dealer funding spreads are already at historic highs, the system has little room to absorb additional stress.
