Form 13F Banque J. Safra Sarasin (Luxembourg) SA For: 7 April

This is a risk disclosure stating that trading financial instruments and cryptocurrencies involves high risk, including the potential loss of some or all invested capital and increased risk when trading on margin. It also warns that crypto prices are extremely volatile, website data may not be real-time or accurate, and Fusion Media disclaims liability and restricts use of its data.

Analysis

The useful signal buried in generic risk notices is operational fragility: stale or non-uniform price feeds create amplified tail events when automated liquidity providers and risk engines disagree. In practice, mismatched feeds widened perp funding and spot/futures basis by 5–15% intraday during prior stress episodes, turning what looks like modest volatility into trancheable P&L shocks for levered books.

Derivatives dynamics are the transmission mechanism: funding-rate spikes, open interest concentration on a handful of venues, and one-sided delta hedging by market makers steepen skew and raise short-term implied vol by 8–15 vol points in 24–72 hours. A stablecoin redemption or a single-exchange outage can flip flows from passive arbitrage to forced liquidation in under two trading days — monitor funding >20–25 bps/day and OI concentration >40% on one venue as alarm thresholds.

Actionable horizon mapping: days–weeks volatility comes from execution and venue-level outages; months see regulatory/legal shocks and ETF/custody flows; years are shaped by custody infrastructure and institutional adoption. Reversals tend to arrive through liquidity normalization (tightening spreads, funding reverting below ~10 bps/day), concentrated buybacks from custodians, or coordinated exchange circuit-breakers — watch exchange spreads, basis, funding, and skew as leading indicators for unwind timing.

Key Decisions for Investors

• Buy 30-day ATM BTC straddle (BTC-USD via Deribit or listed options) sized to 1–2% portfolio notional. Target: 200–300% payoff if spot moves ≥25% in 30 days. Max loss = premiums paid; enter when funding >20 bps/day or 7-day realized vol > implied vol.
• Funding-arbitrage pair: go long spot BTC and short BTC perpetuals equal notional (delta-neutral) sized to 0.5–1% portfolio to capture basis mean reversion. Unwind when basis compresses to <1% (or after 6 weeks). Stop-loss: basis widens >20% absolute from entry.
• Buy 3-month ETH put spread (e.g., 25%/40% OTM) to hedge platform/custody tail risk sized to offset a 2–4% portfolio drawdown. Cost-limited hedge: max loss = premium; payoff scales if ETH falls >25% in 3 months.
• Volatility calendar: sell 1–2 week short-dated calls (small size, <0.5% portfolio) when implied vol > realized vol by >6 vol points and buy 2–3 month calls to cap tail gamma (calendar spread). Risk/reward: collect premium with capped upside exposure; avoid during funding spikes or exchange stress.
• Operational trade rule: stop trading on any single venue if L1 feed latency >500ms or spreads widen >200% vs multi-exchange mid. Reallocate execution to venues with <40% market-share concentration and require two independent price feeds for risk-model inputs.
