Crypto Risk Management: Learning to Live with Volatility
Crypto is the most volatile asset class an ordinary portfolio ever admits: a 10% daily move in Bitcoin is unremarkable, and 30% weeks litter its history. That is a reason not to avoid crypto, but to size it deliberately. Risk management here means putting numbers on volatility, not fearing it.
Size by risk contribution, not percentage
"5% of the portfolio in crypto" sounds innocent; but an asset 3-4× as volatile as the index can generate 20-30% of total portfolio risk from that 5% weight. The right question is not "what percent is crypto?" but "what share of my portfolio VaR comes from crypto?" In Kuantile this is easy to see: run the analysis with and without your crypto and compare the VaR — the difference is crypto's risk bill.
"Digital gold" or leveraged Nasdaq?
Crypto's correlation with equities is regime-dependent: through 2020-2022 Bitcoin tracked the Nasdaq at 0.5-0.7, behaving like a leveraged tech index; in other periods it decoupled. "It hedges my portfolio" is not a fact but a claim to be measured. Check BTC's cell against US stocks in your correlation matrix; if it's dark blue, your crypto adds dose, not diversification. In TRY terms a second dynamic appears: crypto is dollar-priced, so on lira-shock days its TRY value jumps with the currency — for a Turkish investor, crypto is also an accidental currency position.
What the stress tests say
The 2022 "Crypto Winter" (LUNA/FTX) window is one of Kuantile's preset scenarios: BTC fell ~65% in that stretch, and the test shows what your whole portfolio would have endured, in TRY. A warning about young coins: a few years of price history leaves them "not covered" in older scenarios, hiding their tail risk. Giving a large weight to an asset with a short history is sailing without a map.
Three practical rules
- Size: keep crypto's VaR contribution below a share of total VaR you consciously accept (say, one third).
- Discipline: after big rallies the crypto weight inflates itself; rebalance back to target.
- Honesty: if you claim to be long-term, look at the −60% scenario and ask yourself whether you would really hold. If you would sell there, you are not long-term.
