FTSE Russell has unveiled a proposal to lower the public‑ownership threshold for non‑UK companies listed on the FTSE 100 from 15% to 10%. The change would let overseas firms meet the index’s liquidity criteria with fewer shares held by the public, easing entry for global investors in London markets today.

Reducing the requirement aligns the FTSE 100 with the FTSE 250 and the FTSE Global Equity Index Series, where 10% is standard. Analysts say the move could attract more multinational names, boosting the index’s diversification and potentially raising trading volumes as foreign capital seeks a benchmark presence in London today.

Investors will monitor the regulator’s approval, expected within the next quarter. If adopted, the rule change could prompt a wave of new listings and alter the composition of the FTSE 100, affecting fund managers who track the index and the companies that benefit from higher visibility for global investors today.
