Market Daily: UK gilt yield hits 6% as FTSE slides and US bonds rebound

The day ahead

Thursday’s UK bond sell-off and sharp FTSE fall provide the market backdrop for Friday. The 30-year gilt yield touched 6% and the FTSE 100 closed down 1.68%, while US Treasury yields later eased and Wall Street finished slightly higher. Alongside those completed-session moves, the Competition and Markets Authority cleared E.ON’s anticipated acquisition of OVO Energy at Phase 1 on 1 October. Clearance removes a competition-review obstacle; it does not mean the deal has completed.

In the United States, Federal Reserve Vice Chair Philip Jefferson said inflation risks remained tilted upwards after September’s quarter-point interest-rate rise. September’s decision is complete, whereas future policy remains dependent on economic data, the outlook and the balance of risks.

The US Securities and Exchange Commission proposal would provide registered investment advisers and regulated funds with additional ways to safeguard eligible crypto assets. It is a proposal open to public comment, not a rule already in force.

News selection closed at 06:10:23 British Summer Time, or 05:10:23 UTC, on Friday 2 October 2026. This was before the usual early-morning UK company-announcement period. Cryptocurrency observations were recorded separately at 05:08:20 UTC while those markets were trading continuously.

UK Market Update

Gilts and shares fall together

In Thursday 1 October’s completed UK session, the FTSE 100 closed at 10,428.27, down 1.68%, and the FTSE 250 fell 1.62%, according to Sharecast’s London market report. The 30-year UK government bond yield touched 6% during the session. A yield rises when the bond’s price falls, so the 6% was an intraday level, not a quoted closing yield. NatWest, Lloyds, Barclays and HSBC each lost at least 4% in the same report.

Long-term borrowing costs influence the rate at which investors value future profits and can weigh on companies that need to refinance debt. These observations show a broad UK sell-off, but they do not establish a single cause for every bank or share-price move. Friday’s UK cash market had not opened at this edition’s 06:10 BST news cut-off.

E.ON clears the first UK competition hurdle for OVO

The CMA announced on 1 October that it had cleared the anticipated acquisition of OVO Energy by E.ON SE, acting through E.ON UK Limited. The authority identifies this as its Phase 1 clearance decision and says the full decision will be published shortly.

Clearance means the transaction has passed the CMA’s initial merger-review stage. It does not mean E.ON already owns OVO or confirm that every contractual condition has been satisfied.

The decision removes one source of uncertainty surrounding the transaction. The full decision should provide more detail about the CMA’s competition assessment. Investors can then compare that reasoning with any subsequent completion announcement and the combined company’s operating plans.

For customers, ownership is only one influence on outcomes. Household energy bills also reflect wholesale costs, network charges, levies and regulation. Greater scale may spread some operating costs over a larger customer base, but it does not guarantee lower prices or better service.

William Grant shows pressure in premium spirits

Family-owned William Grant & Sons reported profit before tax of £337 million for the calendar year ended 31 December 2025, down from £388 million in the previous year, according to original reporting by Daily Business. Turnover fell 4% to £1.758 billion. The company said difficult market conditions were being felt across the spirits industry and described performance across its portfolio as varied.

The figures are newly reported but concern an accounting period that ended nine months ago. William Grant is privately owned, so this is sector evidence rather than a directly tradeable company result. It nevertheless provides a comparison for listed drinks producers: premium brands do not make a business immune to weaker demand, and performance may differ significantly by brand, category and region.

The report also says William Grant acquired The Famous Grouse and Naked Malt brands and invested in its brands and Girvan distillery during the year. Investors comparing drinks companies should separate current trading from expenditure intended to support future capacity, then examine inventory, margins and cash generation where those figures are available.

US Market Update

Wall Street recovers as Treasury yields ease

US shares recovered from earlier weakness on Thursday 1 October. AP’s completed-session figures put the S&P 500 at 7,666.45, up 0.2%; the Dow at 50,926.56, up less than 0.1%; and the Nasdaq at 26,871.60, also up less than 0.1%. Those are Thursday’s closes, not live Friday prices. The recovery followed a reversal in US Treasury yields, although the sequence alone does not prove what caused each index move.

Jefferson keeps the emphasis on inflation, not a preset rate path

Federal Reserve Vice Chair Philip Jefferson said on 1 October that risks to economic activity and employment appeared roughly balanced, but risks to his inflation forecast were tilted upwards. His Federal Reserve speech recorded 12-month personal consumption expenditures inflation of 3.4% in August, still above the Fed’s 2% target.

Jefferson supported the Federal Open Market Committee’s completed September decision to raise the federal funds target range by 0.25 percentage points to 3.75% to 4.00%. A quarter of a percentage point is also called 25 basis points. He did not announce the next decision. He said future adjustments should depend on trends in the data, the evolving outlook and the balance of risks.

His explanation identifies several pressures that investors should keep distinct. Higher energy prices contributed to the recent increase in headline inflation. Strong artificial-intelligence infrastructure investment supported economic growth, while AI-related demand also contributed to higher production costs for relevant goods and services. Trade-policy changes were another part of the economic backdrop. The speech does not establish that any one factor will determine the next rate move.

Jefferson also said yields across the maturity range had increased further since the September meeting, which he interpreted as a sign that investors were reassessing the macroeconomic landscape. When government borrowing rates rise, companies face a more demanding financing and valuation environment, particularly when much of their expected profit lies far in the future.

Global Markets

Europe bears more of the bond sell-off

The 1 October sell-off was not confined to London. AP reported that broad share indexes fell 1.7% in London, 1.6% in Paris and 1% in Frankfurt, while the main US indexes ended slightly higher. The contrast matters: investors faced the same debate about inflation and borrowing costs, but national bond markets and share indexes did not move in lockstep.

ECB President Christine Lagarde’s 1 October speech addressed risks from AI use in finance, while Federal Reserve Vice Chair Philip Jefferson discussed US energy inflation and AI-related investment. Bringing those assessments together is an editorial comparison, not a claim that either speech caused Thursday’s market moves. For investors, the useful distinction is between spending on AI infrastructure now and the future revenue or productivity that companies still need to demonstrate.

Bonds, Currencies and Commodities

UK gilts spike, US yields reverse and oil rises

The 30-year UK gilt yield touched 6% during Thursday’s session, according to Sharecast. In the US, the 10-year Treasury yield reached about 5.34% intraday, then eased. The US Treasury’s daily par-yield curve recorded 5.24% for 1 October, down from 5.29% on 30 September. That is a fall of 0.05 percentage points, or five basis points, between the published daily observations. The intraday high and daily Treasury reading are different measurements; neither should be presented as a live Friday quote.

A bond yield is the annualised return implied by its price and promised payments. Higher yields can raise refinancing costs and the return investors compare with shares, but Thursday’s US reversal shows why a single peak cannot describe the whole session. A rate-sensitive company with near-term debt may feel the effect sooner than one with long-dated fixed borrowing.

Oil added another inflation concern. Reuters reported that the new front-month December Brent crude futures contract settled on 1 October at $102.31 a barrel, up $4.28 or 4.37%. It linked the rise to reports of Chinese fuel-export restrictions and further US military deployments to the Middle East. This is a dated futures settlement for a specified delivery month, not a live spot-oil price or proof of future inflation. No separate currency or gold quote is asserted here.

Crypto

The SEC proposes a narrow route to adviser self-custody

The SEC proposed rules and amendments on 1 October covering how registered investment advisers and regulated funds may safeguard crypto assets. According to the SEC announcement, the framework would permit crypto assets to be held in self-custody in certain circumstances and allow state trust companies to act as custodians.

This is not the same as an individual holding their own wallet keys. SEC Commissioner Hester Peirce explained that the proposal uses “self-custody” to describe an adviser acting as custodian for client assets. Her statement on the proposal says an adviser would initially, and then quarterly, have to determine that no permitted custodian was available before using this route.

A state trust company would not become an automatic choice merely because it carried that label. Peirce said an adviser or regulated fund would need a reasonable basis for believing that the company was authorised by the relevant state banking authority and maintained written safeguards against theft, loss, misuse and misappropriation.

The proposal’s scope also matters. Peirce said crypto assets are not all subject to the custody requirements. The proposed investment-adviser amendments would apply to crypto assets that are funds or securities, while the regulated-fund provisions concern securities or similar investments. Classification therefore remains central to deciding which requirements apply.

The public-comment period is due to remain open for 60 days following publication of the proposing release in the Federal Register. Until the SEC adopts, changes or withdraws a final rule, firms should not describe these proposed options as current permission. Investors should continue checking which legal entity holds an asset, who controls its keys and what contractual or regulatory protection applies.

The fixed crypto sample moved higher, led by Solana

The following panel is a crypto-only snapshot. It covers five selected assets quoted in US dollars and does not represent every digital asset or any traditional market.

At 05:08:20 UTC on 2 October, while crypto markets were trading continuously, all five assets in the fixed sample had positive rolling 24-hour changes. Solana recorded the largest percentage increase in the group at 3.61%, followed by Bitcoin at 2.93%. XRP rose 1.36%, Ethereum 0.92% and Chainlink 0.67%.

These are rolling observations rather than formal daily closes, and they do not establish why prices moved. Bitcoin was observed at US$86,604, Ethereum at US$2,734.39, Solana at US$123.44, XRP at US$1.53 and Chainlink at US$14.59. The sample compares assets with different sizes and designs, so equal percentage changes would not mean equal changes in market value.

The fixed Bitcoin-focused sentiment reading was 72, classified by its provider as “Greed”, compared with 74 for the preceding reading. It is a mood indicator based on the provider’s methodology, not a prediction or instruction to trade. Later provider displays may show different values.

AI, Technology and Investor Tools

Lagarde separates model herding from agent risks

ECB President Christine Lagarde said on 1 October that nearly nine in ten significant euro-area banks use generative AI. In her European Central Bank speech, she distinguished today’s mostly limited-autonomy uses from emerging agents that can pursue goals with less human direction, including devising trading strategies or finding weaknesses in trading infrastructure.

Lagarde attributed a warning about similar models and similar trades to the European Systemic Risk Board’s Advisory Scientific Committee. She drew a separate distinction for AI agents: agents trained on firms’ own data could make trades less correlated, while greater autonomy introduces a risk of misalignment, when an agent pursues a goal in a way its overseers did not intend or detect. She also warned that an attack on shared technology could disrupt several firms at once. These are potential systemic risks, not evidence that agents caused Thursday’s market moves.

For an individual investor, this supports a practical control framework:

A safer AI-assisted research workflow

1. Use an agent to identify questions and source documents, not to replace those documents.
2. Record the instrument, period, currency and observation time for every figure.
3. Check consequential claims against the company filing, regulator release or attributable original report.
4. Keep research, investment decisions and order execution as separate steps.
5. Require human approval for orders and recheck the asset, quantity, order type and price limit.
6. Limit connected accounts, permissions and available funds while evaluating a new tool.

These controls cannot eliminate model errors, shared-data problems or cyber risk. They can reduce the chance that a fluent but mistaken answer moves directly from research into execution.

OpenAI sets out access to its agent tools

OpenAI launched its Agents API in public beta on 10 September, so beta access was not a new 29 September launch. The company says it is available to developers and charges no additional API fee beyond the tokens and tools used. It provides hosted execution and tools for building longer-running agents. OpenAI’s 29 September DevDay material revisited those capabilities rather than first announcing the beta.

OpenAI separately introduced Dots on 29 September as persistent agents with a cloud computer and connected applications. The company says access is rolling out to eligible Pro and Business Premium users, with Enterprise access subject to an administrator enabling the beta; its first Dot is included in eligible plans at no extra cost, while deeper work has an allowance. Eligibility depends on the market and plan, so UK access should be checked against OpenAI’s current eligibility page rather than assumed. Dots and the developer Agents API are different products with different access and billing terms.

Persistence may help when a research workflow must revisit filings, assumptions or a watchlist. It also increases the importance of permission design. Users should inspect which data sources an agent can reach, what actions it may take and how its work can be reviewed before connecting brokerage, wallet or sensitive financial information.

What to Watch Next

• E.ON and OVO: watch for the CMA’s full Phase 1 decision and any separate announcement that the acquisition has completed. Clearance on 1 October was not completion.
• SEC crypto custody proposal: the comment period is due to run for 60 days after the proposing release appears in the Federal Register. Check that publication date before calculating the deadline, and distinguish submitted comments from an adopted final rule.
• US jobs report, 2 October: the Bureau of Labor Statistics schedules September’s Employment Situation release for 08:30 Eastern Time, or 13:30 BST. It had not been released at this edition’s 06:10 BST cut-off. Compare the figures with Jefferson’s assessment rather than treating his view as a pre-commitment by the committee.
• AI tools: verify beta status, geographical access, account permissions and human-approval settings before incorporating an agent into financial research or execution.
