A 55.33% weekly range and a -7.67% hour force a margin reset for leveraged BTC accounts
Should 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?
The market facts are real; the decision maker is illustrative.
The week and the position
In the week of 16 March 2020, BTC opened at 5360.33, fell to 4442.12 by Monday 11:00 UTC after a -7.67% hour at 10:00 UTC, then rebounded to a 6900.00 high on Friday and closed at 5816.19, up 8.5%. The weekly range was 55.33% and annualised realised volatility 165.6%, with dollar volume 1.87 times the prior 12-week average and the market still 58.34% below its 52-week high. Perpetual funding averaged -0.0164% per eight hours, reaching -0.0904%. An illustrative risk team sets initial and maintenance margin for leveraged clients, and its current terms predate this week.
Judgment
A -7.67% hour inside a 55.33% weekly range means a liquidation can be filled well beyond the price the margin was sized against; weekly dollar volume of 6.72 billion was 1.87 times the prior 12-week average, though that figure covers the whole week. Raise initial margin on BTC now, set from the worst hourly and daily moves rather than prior weekly averages, and widen the gap between initial and maintenance so liquidation is triggered before a single hour can overshoot it. Existing positions keep their terms but face intraday top-ups. Accept lower leveraged volume.
What would change it
If the team's own liquidation records this week show fills close to trigger prices, the case for a larger initial margin weakens. If hourly moves stay below the prior range for several weeks and realised vol falls well under 165.6%, the requirement can be eased back.
What sets this case apart
The margin question turns on how far price can travel inside one hour and how thin volume is at that moment, not on the week's positive close.
