Large (“Block”) Trades Can Have Deferred Publication
What it is: If a trade is big enough to move the price (a block trade), the LSE allows the participants to report it with a delay—often up to a few minutes or even longer, depending on size and instrument.
Why: Immediate disclosure could cause sudden price swings, making it harder for the buyer or seller to finish their full order without the market moving against them.
In short:
Market makers don’t delay reports arbitrarily; they use the LSE’s official deferred-publication rules to prevent undue market impact and to manage their own risk. These delays are transparent and governed by the LSE’s Trade Reporting & Transparency rules, not a secret loophole.
