FTSE 100 Inclusion20 Apr 2026 14:15
There seems a lot of optimism that Harbour will shortly be included in the FTSE 100. I’m not sure this will happen, especially if the situation in the middle east is resolved by late May. I'd imagine we would need oil over $100 in late May for us to be included.
For info, the market cap cut-off is 22nd May 2026 for inclusion in the June review.
How proposition and relegation occurs is that the 90/110 rule applies, where the incoming constituent must be in the top 90 constituents by market cap and a current FTSE 100 constituent must be below the top 110 by market cap. This is to prevent churn every quarter.
According to data on the following links, we would be sitting in position 94 and therefor outside the threshold for change. There also looks to be only one company which is below the 110 position – BKG (110th position)

What helps us is that this June review is the annual review (Mar, Sept and Dec are classed as quarterly reviews). At the annual review, FTSE Russell perform the annual reconsitition of the FTSE UK universe which includes full liquidity testing over the prior 12 months, nationality reassessments and reconfirmation of index universe membership. This leads to a lot more constituent changes at the annual June reviews (Jun 2023 – 4 swaps, Jun 24 - 4 swaps, Jun 25 – 3 swaps) than in the other quarterly reviews (averaging 1 swap per quarter over the last 3 years).
