Markets This Week: Jackson Hole Changes the Conversation

Every August, central bankers gather in Jackson Hole, Wyoming, and every few years one of those gatherings actually changes the direction of markets. The week ending 28 August 2026 produced one of those occasions. Kevin Warsh, delivering his first keynote at the symposium as Federal Reserve chairman, told his audience — in unmistakably deliberate language — that inflation was running too high. Markets heard the message instantly: by Friday's close, the probability that the Fed raises interest rates at its September meeting had jumped to better than even, with market-implied odds spiking to around 57%.

For anyone who spent the last two years reading about when rate cuts would resume, that sentence deserves a second look. The conversation has changed. This week's review takes stock of where the major markets ended, and what a business owner — rather than a trader — should actually take from it.

Wall Street: a winning week with a nervous finish

The American indices absorbed the Warsh speech on Friday and gave back some ground, but still closed out a positive week — the Dow's first winning week in three:

The S&P 500 slipped 0.25% on Friday to 7,711.76, but advanced around 0.5% across the week.
The Nasdaq Composite fell 0.52% on Friday to 26,402.42, yet finished the week roughly 0.9% higher.
The Dow Jones Industrial Average was essentially flat on Friday at 53,559.99, up about 0.5% on the week.

The week's real drama belonged, once again, to Nvidia. The chipmaker reported strong earnings and an upbeat outlook mid-week and jumped nearly 9% on Thursday — then surrendered about 4.5% on Friday as the hawkish tone from Jackson Hole swept through the semiconductor complex. It still ended the week higher, and the pattern is instructive: the AI capital-expenditure story remains fundamentally intact, but it is now sharing the stage with monetary policy in a way it has not had to for some time. Growth valuations and rising rates are old adversaries.

London: the FTSE catches its breath near 10,800

The FTSE 100 spent the week consolidating around the 10,800 mark, closing Thursday at 10,800 after a 0.72% decline — its second consecutive down session — with banking, healthcare and commodity names leading the retreat. Shell and BP fell 1.5% and 1.2% respectively as oil declined for a fourth straight session, while the week's standouts ran the other way: Computacenter up 4.7%, Sage up 4.0% and the London Stock Exchange Group up 3.8% — a reminder that the technology and software names within the FTSE have been doing quiet work while the headlines concentrate on miners and banks.

Perspective matters here. An index at 10,800 is an index that has climbed a very long way over the past two years, and a two-session pause after that run is unremarkable. The more consequential UK story sits in the rates market.

The UK rates picture: the hike that moved to 2027

The Bank of England's base rate stands at 3.75%, and here is the detail that would have seemed strange two years ago: the live debate in the UK is not about the timing of the next cut but about the timing of the next hike. UK inflation printed at 2.9% in July, up from 2.6% the month before — above target and moving the wrong way, though hardly runaway.

This week the market pushed its expectation for the next Bank of England move out from late 2026 into 2027, helped by the easing in oil prices late in the week, which soothes the near-term inflation arithmetic. So the UK sits in a genuine pause: a central bank on hold, data pulling gently in both directions, and a market that has learned not to front-run it.

Sterling: the dollar reasserts itself

The pound ended the week at around $1.3531, its weakest level since mid-August, down on the week as Warsh's remarks did what hawkish Fed talk always does — support the dollar. The move is modest in isolation, but the mechanism is worth internalising: when the Fed sounds hawkish and the Bank of England sits still, the rate differential shifts in the dollar's favour, and sterling softens without anything having "happened" in Britain at all.

For importers paying dollar invoices, a weaker pound is a real cost increase; for exporters invoicing in dollars, it is a quiet tailwind. Either way, it is precisely the kind of movement that rewards the disciplines we set out in our cross-border payments series: know your exposure, measure your conversion costs, and make currency decisions deliberately rather than at the moment an invoice falls due.

Commodities: gold's sharp Friday, oil's easing week

Two commodity stories bracketed the week. Gold — which has had an extraordinary year, up roughly 29% over twelve months — fell sharply on Friday, dropping over 3% to around $4,454 an ounce as the prospect of higher US rates raised the opportunity cost of holding metal that pays no yield. Brent crude ended the week near $88 a barrel, down for four consecutive sessions but still around 30% higher than a year ago — a level that continues to feed through into fuel, freight and energy-intensive input costs for UK businesses.

We examine both moves properly in a companion article this week.

What a business owner should actually take from this week

The era of assuming rates only go down is over — again. Whether or not the Fed hikes in September, the mere fact that a hike is the central scenario changes borrowing mathematics everywhere. If your business carries floating-rate debt or is planning to refinance, this is the week to re-run the numbers with less comfortable assumptions.
Currency moves are being driven by policy, not events. Sterling's slide this week came from a speech in Wyoming. If your margins are exposed to the dollar, that exposure deserves a written policy, not ad-hoc reactions.
The AI investment cycle is intact but no longer unopposed. Nvidia's week — up 9% on earnings, down 4.5% on rates — is the whole story in miniature. For businesses, the practical consequence is benign: the tools keep getting better and cheaper even while the shares gyrate.
Energy costs are structurally higher than a year ago. Oil easing to $88 is welcome; oil at $88 is still oil up 30% year on year. Budgets for 2027 should assume the higher plateau, not the old one.

Markets ended the week orderly but repositioned: rate-hike risk is back in the price, the dollar is firmer, and the easy consensus of early summer has gone. That is not a crisis; it is a change of weather. Businesses that notice the weather early get to bring the washing in.
