Wall Street Balance Sheets Maxed Out: Banks Urge Hedge Funds to Add Short Positions to Mask Rising Gross Leverage
nashnova research
Multiple Wall Street banks have hit lending capacity limits. Barclays auctioned capital internally from other desks to keep lending; Goldman and others urged hedge funds to add shorts to shrink balance-sheet usage on paper — yet gross leverage has risen to ~214%, and the risk of a systemic deleveraging remains unresolved.
How did Barclays get around its own risk limits?
During the Asian AI-equity trading boom, Barclays hit its internal financing cap for hedge-fund clients — and instead of pulling back, it moved the goalposts.
The fix: the macro rates desk auctioned part of its capital quota to the prime brokerage unit — the division that lends to, custodies for, and executes trades on behalf of hedge funds — run under Adeel Khan's global markets group.
This means → the risk ceiling was never formally breached, but capital earmarked for other businesses was redirected to keep the lending machine running. The goalpost moved; the game continued.
UK banking regulators began reviewing this space in July and by September zeroed in on London prime brokers' financing of Asian equities.
What does the Situational Awareness blowup reveal?
The irony: Barclays had refused to onboard hedge fund Situational Awareness as a client, citing AI-sector concentration risk. The fund, founded by Leopold Aschenbrenner, ran roughly 4× leverage via total return swaps — contracts that let a fund gain exposure to stock moves without buying the shares outright.
When AI stocks corrected in July, the fund was forced to dump its entire public portfolio at a roughly 10% discount to Ken Griffin's Citadel. AUM collapsed from about $45 billion to ~$10 billion in days.
In plain terms = Barclays dodged that particular mine, yet still pushed its own Asian financing so far that it had to borrow capital from other desks — risk appetite never truly pulled back.
Are other major banks in the same position?
Goldman CFO Denis Coleman said this month that equity-financing demand continues to exceed industry capacity, allowing Goldman to "deploy resources selectively." In July he noted demand in prime brokerage "far in excess of what we would want to intermediate."
UBS CFO Todd Tuckner said in July that the bank's equity balance-sheet usage in prime brokerage was moving toward "greater moderation."
This reflects a sector-wide condition — the entire financing pipeline is running near full. Demand far outstrips supply, and banks are picking their clients.
What warning signs appeared before the blowup?
Bloomberg strategist Simon White flagged the issue as early as June: futures financing rates were surging on soaring total-return-swap demand, and dealer leverage exposure via futures and swaps had hit record levels.
Equity inventories climbed to $223 billion, and White explicitly warned that "dealer balance sheets may face a supply bottleneck due to regulatory constraints."
This means → Barclays' internal auction that followed was a direct confirmation of exactly that bottleneck. The warning signals were already there; expansion did not stop.
How does the "add more shorts" trick actually work?
Once balance-sheet space ran out, the banks' "solution" was to encourage hedge funds to hold more short positions. Cash raised from shorting can be used internally to finance long positions — on paper, balance-sheet usage drops, but actual leverage doesn't shrink at all.
Goldman's own data confirms this: as of the week ending October 18, US long/short hedge-fund net leverage fell to 43.7%, a five-year low — but nearly all of the decline came from adding shorts, not cutting longs.
The breakdown: since July 31, long leverage dropped just 0.5 percentage points to 128.8%, while short leverage jumped 8.0 pp to 85.1% — a five-year high. Gross leverage stood at roughly 214%, higher, not lower, than after the Situational Awareness blowup.
In plain terms = net leverage fell only because shorts grew faster than longs — like taking out a new loan with your left hand to "hedge" the debt in your right. Total debt actually went up.
What is the biggest unresolved risk right now?
UBS trader Torsten Sippel warned that hedge-fund net exposure has dropped to the 30th percentile over five years, yet gross leverage remains above the 90th percentile — "if P&L pressure persists, portfolios face vulnerability to further deleveraging."
Goldman's Lee Coppersmith acknowledged that if performance pressure continues, "there is indeed room to deleverage further by selling longs and covering shorts."
This means → at 214% gross leverage, if longs and shorts move against each other simultaneously — as happened in July when AI-infrastructure stocks fell and software names rallied — the supposed "hedge" breaks down fast. UK regulators are still reviewing, and when a systemic deleveraging triggers is the market's core unresolved risk.
