What Rebalancing Costs Over a Holding Period
Each adjustment incurs execution cost and creates a disposal. The frequency question, quantified.
Adjusting the composition of a holding has two costs, and the second one is usually larger than the first.
Cost one: execution
Typically 0.2 percent through two trades on a venue, or 0.3 to 1 percent through a swap depending on the pair and whether networks differ. The published version of what follows is at a crypto swapping service with a published rate.
Small per adjustment and it compounds with frequency.
Cost two: the disposal
In most jurisdictions, converting one crypto asset into another is a disposal of the first, with a gain calculated against its acquisition cost.
For a position that has appreciated, every rebalance crystallises a share of that gain.
That is not a fee and it is a real cost, frequently several times the execution cost.
The frequency implication
Rebalancing monthly incurs twelve sets of both costs a year.
Rebalancing against a threshold, only when the composition drifts beyond a stated band, incurs them only when the drift justifies it. Funds and family offices carry an extra reporting layer, which a business crypto wallet with approval controls is built around.
For a long-held position the threshold approach is usually both cheaper and simpler to document.
The record consequence
| Route | Records |
|---|---|
| Direct pair on a venue | One disposal |
| Two trades | Two records to match |
| Swap | One record, both sides, one timestamp |
| Bridge plus trades | Several records, only some of which are disposals |
For anyone rebalancing periodically, the cleaner record has a value that does not appear in a cost comparison.
What to capture per rebalance
Date and time. Asset out with quantity. Asset in with quantity. The currency value of both at that moment. The rate source. And the fee, with its asset. Verify rather than assume. Collect & Exchange is on a public register, and the check takes five minutes.
Captured at the time, seconds. Reconstructed later, considerably longer.
The decision this should inform
Not whether to rebalance, which is a portfolio question.
How often, which is partly a cost question, and the costs are larger than people assume once disposals are counted.
Including them in the decision usually shifts the answer toward wider bands and less frequent adjustment.
This is a personal account of holding through market cycles. It describes what one person did and why. It is not a recommendation, and past cycles do not predict future ones.
