Between a Bank of England decision, a packed results diary and US midterm uncertainty, London's leading index faces a demanding few days, and the American labour market has the final word.

Some weeks on the stock market drift by quietly. This is not one of them. By the time the US October jobs report lands on Friday 6 November 2026, investors in the FTSE 100 will have absorbed eurozone Inflation data, an expected Interest Rate rise from the Bank of England, a wave of corporate results and the aftermath of the US midterm elections. The payrolls release closes that sequence, and it could shape the mood heading into the following week.

The index enters this stretch on the back foot. On Tuesday 3 November, the FTSE 100 closed at 10,638.43, down 122.90 points or 1.14% from Monday's 10,761.33. Reuters described it as the index's steepest one-day fall in a month, and it brought a four-session winning run to an end.

Why a US data release matters in London

It may seem odd that a report on American employment could move a UK index. The explanation lies in the composition of the FTSE 100. Many of its largest companies earn a substantial share of their Revenue outside Britain, often in US dollars, and global investors set prices for those shares with one eye on the world's largest economy.

A monthly jobs report is one of the most closely watched snapshots of US economic health. In general terms, it offers clues about hiring, wage pressures and consumer strength. Those clues feed into expectations for US interest rates, which in turn influence the dollar, bond yields and global appetite for risk. A surprisingly or weak reading can therefore ripple across markets well beyond Wall Street.

For FTSE 100 companies that report in dollars or earn heavily in them, currency moves are particularly relevant. Hiscox (LSE:HSX), for example, reports its premiums in dollars, while HSBC (LSE:HSBA) has extensive international operations. A shift in the dollar against sterling can change how overseas Earnings look once translated back into pounds. Sterling stood at about $1.3417 on Monday 2 November.

The road to Friday

Each day this week carries its own potential catalyst, which is why the jobs report arrives as a capstone rather than a standalone event.

Wednesday 4 Novemberbrings eurozone inflation figures, expected at 3.9%. The corporate diary is also busy, with half-year results from Marks & Spencer (LSE:MKS), a trading statement from Barratt Redrow (LSE:BTRW) and third-quarter updates from Coca-Cola HBC (LSE:CCH), Lion Finance (LSE:BGEO), Prudential (LSE:PRU), Smith & Nephew (LSE:SN.) and Weir (LSE:WEIR). Ahead of the M&S figures, Investec's head of retail and consumer , Kate Calvert, forecast half-year pre-tax profit of £397m, more than twice last year's £184m, as the retailer moves on from a serious cyber-attack last year.

Thursday 5 Novemberis the centrepiece for UK investors. The Bank of England is widely expected to raise Bank Rate by 25 basis points from 3.75% to 4%, which would be its first increase since August 2023. Money markets had fully priced four quarter-point hikes by next September, according to LSEG data cited by Reuters. The same day brings half-year results from BT (LSE:BT.A), National Grid (LSE:NG.) and Auto Trader (LSE:AUTO), a first-quarter statement from Diageo (LSE:DGE), and third-quarter updates from Next (LSE:NXT), Croda (LSE:CRDA), Howden Joinery (LSE:HWDN), M&G (LSE:MNG) and Metlen Energy & Metals (LSE:MTLN).

Running in the background is the result of the US midterm elections, held on Tuesday 3 November for all 435 House seats and 35 Senate seats.

The global backdrop shaping the reaction

How markets respond to Friday's numbers will depend partly on the wider context, and that context is dominated by energy. Brent Crude settled at $104.77 a barrel on Monday after a 7.63% drop, and Reuters reported a further slide of about 2% on Tuesday as investors weighed talks aimed at ending the wars in Ukraine and Iran. Reuters also noted that elevated oil prices have fuelled inflation fears and that many central banks have raised rates.

In that environment, labour market data takes on extra significance. If employment and wage growth look , investors may worry that inflation pressures will persist, potentially reinforcing expectations of tighter policy around the world. Softer figures could ease those fears but raise questions about growth. Neither outcome is automatically good or bad for equities; much depends on how the numbers compare with expectations and on what policymakers say afterwards.

Tuesday's session showed how fragile sentiment already is. The FTSE 350 basic resources index fell 2.6% as copper dropped to a multiweek low, and the FTSE 350 banks index lost 1.6% ahead of the Bank of England decision. Associated British Foods (LSE:ABF) fell 2.2% after forecasting lower annual profit, and Coca-Cola Europacific Partners (LSE:CCEP) declined 2.1% after flagging cost pressures. Hiscox bucked the trend with a 2.9% gain after reporting a 9.5% rise in nine-month premiums.

Amundi Investment Institute's Alessia Berardi noted that the market was pricing a full hiking cycle, adding that "one or two moves will be enough" in her view. Friday's jobs data will be one more input into how investors weigh such arguments, on both sides of the Atlantic.

Key dates to watch

Wednesday 4 November:Eurozone inflation (expected 3.9%); M&S half-year results; Prudential and Weir third-quarter updates.

Thursday 5 November:Bank of England MPC decision; BT, National Grid and Diageo updates.

Friday 6 November:IAG third-quarter results; US October jobs report.

Thursday 12 November:ONS first quarterly GDP estimate for July to September 2026, at 7:00am.

The bottom line

The US October jobs report on Friday 6 November is the last major event in an unusually crowded week for the FTSE 100. After Tuesday's 1.14% fall, investors face a likely Bank of England hike, a heavy results calendar and uncertainty over the US midterms before the payrolls figures arrive. Because so many FTSE 100 members earn abroad, US labour data can influence the dollar, global rate expectations and sentiment towards London's blue chips. How all these pieces fit together may only become clear once the week is over.
