The Brief

Volatility premium reaches 5.6 points as the market leaves compression

Realised volatility on bitcoin has risen to 41.2 per cent from 28.6 per cent in four weeks, and perpetual funding has climbed to 11.4 per cent annualised from 2.1 per cent in mid-August. Investors are being paid to carry risk for the first time since March.

The session text publishes with the edition. Until the brief for this edition is on the desk, this column stays as it is rather than filling itself with something older.

Against this view

Every reading on this page is one the desk can show its working for. Where a figure has no series behind it, the page says so beside the figure rather than in a footnote.

The bottom line

The takeaway publishes with the edition.

That is the session. The Close publishes at 18:00 CET. Past editions

The method is published

Why the banks sit here

The floor and the ceiling are set on Saturday and not moved until the next one.

How the banks work

  1. The desk sets a floor and a ceiling on a Saturday, before the week opens, and publishes them.
  2. They are not moved until the following Saturday, whatever happens in between.
  3. A session is scored on its full twenty-four hour range, not on its close.
  4. A session that finishes outside a bank is marked against the desk, in public.

An asset earns banks when the desk is willing to set them every Saturday and stand behind the verdict. Until then it is watched, not judged, and sits on The Watchlist. Every week is scored on The Record, including the ones we get wrong.
