LME to offer extended “grace period” for enforcement of MVT Rule
The London Metal Exchange (LME) has provided an update on the timelines for market structure modernisation initiatives relating to enhancing liquidity on LMEselect.
In response to Member feedback and to support participant readiness, the LME will be offering an extended “grace period” for the enforcement of the Minimum Volume Threshold (MVT) Rule which will now extend until the 24 August 2026 (having previously been scheduled to finish on 22 June 2026).
During the Grace Period, the LME will be monitoring the activity of sub-MVT inter-office trades and generate example audit requests for Members. To be clear, there will be no obligation for Members to respond to any example audit requests.
The new automated crossing order type, which has been available in the test environment since 2 February 2026, will now go live on 22 June 2026, allowing an additional month of build and test activity. The 22 June 2026 date is in line with the original end of the Grace Period, to support Members who choose to deliver system changes in line with the original timelines.
This revised timeline gives an extended period of two months between the go-live of the automated crossing order type and the end of the Grace Period when the enforcement of the MVT Rule will come into force (previously one month).
