LONDON, 17 September 2026 — FTSE 100 closed at 10,688.47 on 16 September 2026, rose 0.28% from 10,658.13.

FTSE 100 movement since the preceding check

The latest FTSE 100 value is 0.28% above the earlier checkpoint. The earlier FTSE 100 observation was 10,658.1300 at 00:01 IST, 16 September 2026. This FTSE 100 interval comparison is descriptive: it documents two provider states and does not infer a cause. The FTSE 100 provider delay and market-state changes mean the checkpoint calculation should not be treated as an executable gain or loss.

FTSE 100 observation card

FTSE 100 market state at this timestamp

The source marked the regular FTSE 100 session closed before CapKet’s capture. The level is the completed-session observation. The recorded session range was 10,655.98 to 10,735.34, with an opening level of 10,658.22. For FTSE 100, that status separates an unfinished FTSE 100 trade from a completed FTSE 100 result, continuous reference or derivatives observation.

How the FTSE 100 instrument works

FTSE 100 is a benchmark of large London-listed companies whose international revenue exposure can make sterling changes relevant to index returns. This FTSE 100 checkpoint belongs inside the FTSE 100 construction; it cannot represent every related security, physical grade or venue.

FTSE 100 market-structure note

Many FTSE 100 constituents earn substantial revenue outside Britain, which can make sterling changes relevant alongside domestic economic news. The benchmark covers large London-listed companies rather than the whole UK economy. A finished London session is also different from after-hours futures, so the cash close needs its own timestamp and index definition.

Evidence for the next FTSE 100 report

The FTSE 100 verification list includes sterling, gilt yields, energy shares and Bank of England expectations. Those FTSE 100 variables provide context; none proves that one input caused this measured FTSE 100 move.

FTSE 100 comparison dossier

The stored FTSE 100 sequence begins with 10,658.1300 and reaches 10,688.47 in this report. The displayed FTSE 100 move against its provider reference is +0.28%, while CapKet’s separate checkpoint calculation is 0.28% above the earlier checkpoint. The FTSE 100 unit for this page is GBP, and the observation class is cash. Keeping those FTSE 100 fields together prevents a cash close, rolling crypto window, futures contract and physical-market price from being treated as interchangeable. For FTSE 100, the record is useful because it specifies the instrument, value, comparison basis, source state and time boundary in one independently written article.
