Cash equities in London do not open in a vacuum. Index futures trade nearly around the clock and act as the bridge between Asia's session and Europe's cash auction. Beginners who look only at yesterday's FTSE close miss the information already embedded in the overnight futures price.
What futures are doing overnight
FTSE, Euro Stoxx and US index futures move as Asia trades and as US data headlines continue to digest. They incorporate:
- Nikkei and Hang Seng direction
- US Treasury yield shifts
- FX moves that change sterling translation maths for the FTSE
- Weekend or Monday morning political headlines Asia has started to price
By the time London cash opens, futures have usually printed a fair-value gap relative to the previous cash close. The open auction then discovers whether cash participants agree.
Bridge, not destiny
Futures are a bridge. They are not destiny. A firm overnight long futures position can be faded in cash if European real-money flows disagree, if gilt or bund markets flash stress, or if the overnight move was thin. Equally, a soft overnight print can reverse if London likes the levels.
Use futures to update your prior, then let cash confirm. That is the same intellectual habit as treating Asia as input rather than confirmation — because futures are often how Asia's message arrives on a UK screen.
A simple open routine
1. Note futures versus prior cash close for FTSE and Euro Stoxx. 2. Note US futures and the US 10-year. 3. Note cable — soft pound can mechanically support FTSE futures. 4. Note Brent and WTI on split-tape days. 5. Write the Europe risk sentence. 6. Decide confirm / fade / wait before clicking size.
If futures are up mainly because sterling is down, overseas earners may lead cash while domestics lag. That is a different trade from a broad risk-on futures squeeze led by US tech.
Where Mondays go wrong
Traders flatten Friday's mental model onto Monday futures, ignore European fiscal colour, and treat a Tokyo Fed-pause bid as a cash order for the FTSE. Futures will happily express that mistake until the open auction and the first hour invent a better story.
Risk note
Futures are leveraged instruments. Educational discussion of how they bridge sessions is not a suggestion to trade them, size them, or use them as a shortcut around cash discipline. If you use them at all, define invalidation in advance and respect the gap between thin overnight liquidity and the London open.
Close
Fair value in plain English
Professionals talk about fair value as the futures level implied by the cash index, interest rates and dividends. Beginners need only the practical bit: overnight futures can look "up a lot" partly because they are adjusting to FX and yield shifts, not only because someone is wildly bullish UK equities. Always ask what share of the futures move is sterling, what share is global risk, and what share is UK-specific news.
Bridging into the first cash hour
Watch whether the cash open trades through the futures indication or fades it. Trading through with volume and broad participation looks like acceptance. Fading it with narrow leadership looks like scepticism. Re-check after thirty to sixty minutes, when the opening auction noise has settled and gilt markets have had time to speak. Many false continuations die in that window.
Multi-index discipline
Compare FTSE futures with Euro Stoxx and with US futures. If FTSE is alone on a soft pound while Europe and the US are soft, translation may be the bridge — not a global equity impulse. If all three futures boards agree and European spreads are calm, the bridge is carrying a broader message. Agreement is not guaranteed; checking for it is.
