Market cases
A real market week and the decision it posed for an illustrative desk, with a conditional judgment.
189 notes, newest week first
A 14.53% ETH week at 88.2% realised volatility forces a margin decisionShould the exchange raise margin requirements for leveraged ETH clients after this week, or keep current terms and rely on liquidation to absorb a repeat of Wednesday's 4.56% hour?A -17.75% week whose low arrived last, after the limit was already hitShould a fund that cut ETH exposure at its fixed loss limit stay out through the week's close, or redeploy on any rebound day before the low is confirmed?An 11.14% ETH week and 0.0693% funding test a fixed crypto sleeve's weight capShould the allocator raise the sleeve's crypto weight after a fourth up week in five, or rebalance back to target and keep the sleeve's size fixed?A fixed crypto sleeve drifts above target as ETH gains 4.75% and closes 4.24% below its 52-week highShould a fund that holds a fixed share of its money in crypto (its crypto sleeve) sell some ETH now to return to that share, or keep the excess (the overweight) after two weeks of 30.06% and 19.74% gains?A 6.92% hourly reversal at the week's high forces a fresh margin schedule for leveraged clientsShould the risk team raise BTC margin requirements now, using this week's 87.8% annualised realised volatility and the 6.92% hour, or keep the schedule set in the calmer weeks before?An -8.65% hour inside a 19.74% gain week hits a loss limit built for calmer marketsAfter being cut on Sunday's drop, should the fund re-enter ETH at its full size, or return at a reduced size until its loss limit is rewritten for 116.3% annualised volatility?A 98th-percentile +30.06% week leaves the mean-reversion desk fading into strengthShould the desk keep fading intraday ETH overshoots at its usual size this week, or suspend its short-into-strength trades and trade only pullbacks in the direction of the weekly rise?A 93rd-percentile ETH week on thin volume tests a reserve's quarterly lineShould the treasury trim its ETH reserve back to its policy allocation after a 15.84% weekly gain, or leave the position and let the quarterly report carry the mark?A 15.17% rally week, still 51.49% below the high, tests a BTC collateral triggerShould the lender tighten the margin it requires on BTC-backed loans after this volatility, or loosen terms on the strength of the week's 15.17% gain?A 55.33% weekly range and a -7.67% hour force a margin reset for leveraged BTC accountsShould the risk team raise initial margin on BTC leveraged positions now, or keep its existing requirements and rely on liquidation to absorb moves like Monday's hour?A 50.89% weekly range turns one daily receipt conversion into a single price betShould the payments company keep converting each day's receipts at one fixed time, or split each day's amount across several hours to avoid one price print in a 50.89% range?A -44.60% day and a +24.51% rebound land inside one weekly rebalanceShould the fund run its scheduled weekly rebalance into the crash at full trend size, or cut the new position because one day's range exceeded what its sizing model assumes?A -15.93% Sunday forces a reserve's quarter-end reporting callShould the treasury keep its ETH reserve at full size through the quarter's reporting date, or trim it now given ETH's 2.61-point underperformance of BTC and a -15.93% Sunday?Earning 0.0362% per eight hours through a 20.65% fallShould the basis trader keep the spot-plus-perpetual pair at full size, or cut it so the short leg's margin survives a rebound after a 20.65% collapse?A fifth up week with an 8.56% down day inside it tests a weekly rebalanceShould the fund carry its ETH long at full trend size into a fifth up week, or rebalance down to a volatility-scaled size that accepts giving up part of a rally still 23.3% below the 52-week high?One daily conversion meets a 3.11% hour and a Sunday low set late in the UTC dayShould the payments company split each day's receipts across several fixed conversion windows, or keep converting once a day at its single fixed hour?A 33.29% range and paying funding force a margin decision on leveraged ETHShould the exchange raise margin requirements for leveraged ETH positions now, or keep current terms and let the existing liquidation triggers absorb moves of this size?An 8.79% trend on quiet hours and 0.164% funding spikes tests a symmetric quoteShould the desk keep two-sided quotes at its normal spread and inventory limit, or skew the ask side up and cut the limit through a week that gained 8.79%?Four rising weeks and a 96th-percentile gain test a fixed loss limitShould the fund raise its ETH position size after a 21.23% week, or hold size and re-anchor its fixed loss limit to the 65.7% realised volatility and 24.88% range?An 8.32% week in the 84th percentile, 33.16% below the 52-week high, meets a weekly rebalanceShould a weekly rebalancing fund raise its BTC exposure after this week's gain, or keep the current allocation until the trend confirms across two consecutive weeks?A 12.23% week and five straight gains test a quarterly reserve's rebalancing ruleShould the treasury rebalance part of its ETH reserve back to its stated target weight before the quarter closes, or leave the position untouched and absorb whatever the quarter-end mark shows?Collecting 0.0186% per eight hours on a short leg that rode a 26.17% weekly rangeShould the basis trader keep the short perpetual leg at full size to keep collecting funding, or cut it to the margin it would need if price repeated Saturday's 179.50 high?An 18.81% down week and a 4.36% hour force a two-sided desk to reprice its quotesShould a market-making desk cut its quote sizes and widen spreads during the middle of the UTC day, or keep tight two-sided quotes to capture volume running 1.25 times its prior 12-week average?A -23.86% week forces a daily ETH conversion schedule to absorb a -7.86% dayShould a payments company keep converting customer receipts into ETH once a day at a fixed hour, or spread and cap conversions to limit exposure to single-day moves like Thursday's -7.86%?A 42.05% weekly range and an 8.99% hour force a margin rethinkShould the exchange risk team raise margin requirements on leveraged BTC positions to match this week's realised volatility, or hold current levels because funding stayed near zero?A forced cut on Wednesday, then a 13.16% best day and a positive weekly closeShould the fund restore full ETH exposure after its loss limit forced a cut mid-week, or keep the position reduced given that ETH still lost 11.0 points against BTC?Sold volatility into a 19.79% fall and an 8.95% hour, the desk must size a hedge nowShould the options desk hedge its short-volatility book into the week's close, or accept the loss and wait for realised volatility to fall back?A 12.71% hour inside a 19.87% falling week forces a collateral trigger rethinkShould the lender widen its required collateral margin and liquidation cushion on ETH-backed loans now, or keep its existing terms and rely on the current trigger given Tuesday's hourly collapse?A 30.13% weekly range forces a sold-volatility book to price the cost of its own hedgingShould the desk hedge its short-volatility BTC exposure now after a 101.8% realised-volatility week, or stay unhedged and accept directional losses to avoid paying to chase a 30.13% range?A 15.98% Sunday inside a 42.81% weekly range forces a margin reset on leveraged ETHShould the exchange raise initial and maintenance margin on leveraged ETH positions now, or keep current levels and rely on the liquidation engine to clear clients through moves like Sunday's 15.98% day?
