Stress proved it: diversified managers, venues, and hardened DD keep drawdowns contained—so we can pursue higher returns intelligently.


Executive Summary


The October 10 market crash – a 20-minute liquidity collapse triggered by U.S. tariff headlines, exposed systemic fragility across digital-asset infrastructure. Prices for BTC and major tokens diverged sharply across venues as market makers withdrew and oracles lagged, leading to 2–10% platform-level losses among peers labelled “market-neutral.”


Blockstone Capital’s platform remained contained, thanks to disciplined position sizing, cross-manager diversification, and deep due diligence on counterparties, liquidity venues, and oracle design. At the same time, some of our best quant teams generated strong gains of 5–10% on the day, taking advantage of rare pricing inefficiencies during the event.


The 10/10 episode validated once again our thesis: a multi-manager, dispersion-aware architecture that not only caps downside risk during stress events but also enables opportunistic capture of dislocation-driven alpha.


What Happened on Oct 10, 2025


  • 20-minute dislocation: Between 9:00–9:20 p.m. UTC, digital assets sold off sharply after tariff headlines triggered panic selling.

  • Market makers stepped back: Order books emptied, even top venues like Kraken briefly showed no liquidity.

  • Cross-venue price divergence: BTC-USD quotes varied > 4%; Kraken traded near $100K vs Kaiko’s $104K reference rate.

  • Oracle delays amplified stress: On-chain price feeds (Aave, CRV, ENS) lagged real market prices by 30–40%, causing mistimed liquidations (~$180M) and ~$500K in residual bad debt.

  • Peer blow-ups: Two “market-neutral” funds halted trading; some peers suffered 2–10%  drawdowns.


Our Protection and Opportunity Capture


  • Multi-manager diversification: Independent PMs, orthogonal strategies, and segregated venue and custody exposure prevented correlated losses.

  • Strict sizing discipline: No single PM shall drive >150 bps 1-day loss; exposure reviews and rebalancing are triggered through monitored thresholds rather than instant reaction.

  • Robust pricing & oracle DD: Multi-venue reference rates, staleness guards, and circuit-breaker logic mitigate mispricing risk.

  • Counterparty & liquidity diversification: Tiered venue allocation, automated safeguards, and verified MM uptime under enforceable SLAs.

  • Re-underwriting triggers: Any > 3–4 % book drawdown leads to temporary capital pause and risk review before redeployment.

  • Agility and opportunity capture: During the 10/10 event, quant teams capitalized on short-term basis spreads and pricing inefficiencies, generating 5–10 % gains on the day. These returns helped offset drawdowns in market-neutral or DeFi strategies, demonstrating how diversification and team selection create not only resilience but also alpha in periods of market stress.


Proof Points / Controls

Control Layer

Institutional Practice

Sizing

Exposure caps ensure no PM contributes >100–150 bps to 1-day loss or >300 bps over a 5-day cluster, containing localized failures.

Re-underwriting

Any >3–4 % book drawdown triggers immediate capital freeze, forensic review, and risk re-underwriting before redeployment.

Counterparties

Custody, venue, and prime relationships diversified across regulated and non-correlated entities with predefined capacity limits.

Pricing

Positions marked to multi-venue reference rates with variance bands and circuit-breaker logic to prevent mispricing cascades.

Oracles

Multi-source aggregation with batched updates and kill-switch logic to suspend stale or inconsistent feeds.

Liquidity

Market-maker SLAs enforce minimum depth, spread, and uptime; automated safeguards isolate failing venues.

Correlation

Co-moving “neutral” strategies bucketed under shared exposure limits to cap hidden beta during systemic events.

Governance

Stress-tested PMs prioritized for rapid capital redeploy; independent oversight ensures rule adherence and continuous improvement.

BTC-USD Cross-Venue Pricing Dislocation: 9:00-9:40 PM UTC, Oct 10, 2025


BTC traded near $100 K on Kraken as order books cleared, while Kaiko’s multi-venue BTC Reference Rate (orange) stayed above $104 K. The dispersion, driven by liquidity withdrawal and fragmented infrastructure, highlights why diversified pricing and venue DD are critical to control drawdowns and capture mispricing opportunities during stress events.


Closing


  • 10/10 validated once again our thesis: the platform absorbed venue and manager failures exactly as designed.

  • Contained drawdowns + captured alpha: while some peers fell 2–10 %, our quant teams generated 5–10 % returns by trading dislocations.

  • Scaling risk and returns responsibly: this is how we pursue higher performance with institutional discipline and strategic agility.
