Why this matters: London's blue chips just had their best week since April — not on a tech boom, but on defensive stocks, calmer inflation talk and relief over UK fiscal policy
October 17, 2026 — The FTSE 100 closed on Friday, October 16, 2026 up 41.55 points, or 0.4%, at 10,881.90, completing a 3.1% weekly gain — its biggest since early April — after Bank of England Governor Andrew Bailey played down concerns over persistent inflation.

Editor's Highlight: This was a rotation story. Investors fleeing AI-linked stocks sought shelter in staples, beverages, healthcare and defence, while banks sat out Friday's gain on reports of a possible tax hit in the upcoming budget.

How Friday and the Week Closed
London stocks ended the week with further gains on Friday. The FTSE 250 climbed 0.5% to 24,533.90, and the AIM All-Share rose 1.1% to 773.12.
For the week, the FTSE 250 was up 1.3% and the AIM All-Share was down 0.4% — larger companies outperformed. In Europe, the CAC 40 ended up 0.3% and the DAX 40 added 1.0% on Friday.
Newsroom Focus: The headline is the weekly gain. A 3.1% rise, the index's best week in six months, marks a clear change in sentiment toward UK large caps.
Bailey Calms Inflation Fears in Bangkok
Speaking at the International Monetary Fund's annual meeting in Bangkok, Governor Andrew Bailey said evidence of second-round inflation effects was limited.
"To the extent we have seen evidence, it's quite subdued," Bailey said, adding: "It's too early."
He also said Bank of England policy was already restrictive, and the UK economy was "more resilient than we expected it to be." His comments followed remarks by chief economist Huw Pill, who said the four rate hikes priced into markets look overdone.
Analysis Note: If second-round inflation is subdued and hike pricing looks overdone, rate-sensitive sectors get relief. Reporting noted homebuilders surged more than 6% over the week after finance minister John Healey reaffirmed fiscal discipline on Thursday.
Defensives Lead, Banks Lag on Tax Reports
Investors fleeing AI-linked stocks sought shelter in consumer staples and other defensives, offsetting technology selling globally.
On Friday, cigarette maker British American Tobacco rose 2.1% and Johnnie Walker owner Diageo gained 1.9%. The beverages sector and the medical equipment and services sector posted weekly advances of 7.8% and 6.9% respectively.
Defence stocks also extended their run: Babcock International rose 3.6% and BAE Systems climbed 2.6% on Friday.
| Friday risers | Move |
| Babcock International | +3.6% |
| WPP | +3.1% |
| Weir / BAE Systems | +2.6% each |
| British American Tobacco | +2.1% |
| Diageo | +1.9% |
Banks were the exception. NatWest fell 1.2% and Lloyds fell 0.9% on Friday on reports the sector will be hit in the upcoming budget.
The Guardian reported Chancellor John Healey is poised to tax banks more heavily in his October 28 budget. One option under discussion — reversing former chancellor Jeremy Hunt's cuts to the bank surcharge — would raise upwards of £2 billion a year, the newspaper said.
Practical Takeaway: Watch the split, not just the index. Defensives can lift the FTSE 100 even while domestic banks are held back by a budget headline.
Money Is Flowing Into UK Large Caps
The rally is also showing up in fund flows. UK large-cap ETFs attracted $3.38 billion in estimated net inflows year to date, already the biggest annual total since 2020, according to data from Morningstar.
Michael Born, an analyst at Morningstar, said: "Flows into passive funds typically follow performance, but they also reflect investors looking to diversify away from US mega-cap technology and broaden their equity exposure."
In the FTSE 250, e-commerce firm THG also had its best week in six months, surging 30% after raising its annual adjusted core profit forecast on Thursday.
On Friday, the pound was quoted at 1.3339 dollars, gold at $4,176.55 an ounce, and Brent oil at $106.06 a barrel.
What Happens Next
The next test is next week's UK inflation data — the figures Bailey's "subdued" comment will be judged against. The second test is fiscal: the October 28 budget will confirm or remove the reported bank tax.
Investors will also watch whether the defensive rotation continues, and whether ETF inflows keep building on the $3.38 billion already recorded this year.
Bottom Line
The FTSE 100's 3.1% weekly rise to 10,881.90 was built on calmer inflation talk from Andrew Bailey, fiscal reassurance, and a broad move into defensive sectors — not on banks or technology.
What to watch next: next week's inflation data, the October 28 budget and its treatment of banks, and whether the rotation into UK large caps survives its first bad headline.
