US-China optimism lifts Europe and Asia as oil falls
Europe's FTSE 100 rose 0.9% and most Asian benchmarks gained as investors welcomed US-China optimism and an 11-day low in oil, even as France's debt strain deepens.
European stocks rallied at midday and most Asian benchmarks rose overnight, and for once the two halves of the trading day shared a cause: investors reading warmer US-China relations and a sharp fall in oil.
By midday in London the FTSE 100 had climbed 100.10 points, or 0.9%, to reach 10,759.23. Morningstar's midday report attributed the move to US-China optimism and the drop in crude, while noting the gains came alongside warnings about France's soaring government debt and the limited fiscal headroom open to the UK chancellor.
The overnight session had already set the tone. South Korea's Kospi jumped 1.6% to 7,120.25 and Australia's S&P/ASX 200 added 0.2% to 8,748.20, with most Asian benchmarks following Wall Street's positive rally higher, per WSB-TV Channel 2. The read-through in that report is straightforward: sentiment among investors trading the major Asian financial hubs had shifted positive.
The oil price is doing a lot of the work
Oil had fallen to an 11-day low, a move Investing.com tied to growing expectations of diplomacy between the United States and Iran. Cheaper crude is a tailwind for equities because it lowers the cost base for transport, manufacturing and households, which is why shares can rally on an oil move even when that move is driven by geopolitics rather than by demand. It also softens the inflation problem for central banks, which is part of why an energy story can turn into an equity story within a single session.
The same weekly preview flags the risks sitting next to the rally: rising tensions between Houthi forces and Saudi Arabia, and a new US-China AI safety plan. Investing.com identifies both as drivers of market volatility and says they feed directly into energy costs and technology stock valuations. That is the tension in the day. The optimism is real, but it rests on events that can reverse on a single headline, and the AI safety plan in particular sits across the valuations of the largest companies in the index.
What the optimism is priced against
The fiscal backdrop has not changed. France's public debt is projected to rise to 119.3% of GDP in 2026 and 121.7% in 2027, and the government plans EUR 54 billion of savings next year to bring deficits that currently exceed European Union reference levels back into line, according to Serrari Group. That strain is deepening at the same time as French growth stays weak, which is why the debt trajectory keeps surfacing in market commentary even on a day when the tape is green.
Currency markets were less cheerful than equities. The euro declined against the US dollar on Tuesday, trading around 1.1460 during European hours, as the dollar recovered recent losses on a hawkish Federal Reserve tone, FXStreet reported. That matters well beyond the currency desks. The eurozone economy is heavily influenced by data from Germany, France, Italy and Spain, so the euro's level is a read on the bloc as much as on the pair itself, and a firmer dollar tightens conditions for everyone borrowing in it.
Company results underneath the index
Away from the index-level story, Tuesday brought a run of UK corporate numbers that say more about individual businesses than about the macro mood.
Target Healthcare REIT reported final results, with adjusted EPRA EPS, its primary performance measure, up 7.6%. The disposal of 11 care homes produced an annualised ungeared internal rate of return of 11%, and like-for-like rental growth of 3.7% helped offset a 0.6% decrease in total rental income caused by those 11 sales. The company said dividends were fully covered by earnings for the period, per ADVFN's report. For a landlord, that combination, selling assets at a good return while rent on what remains keeps rising, is the orderly version of a portfolio review.
Kingfisher released unaudited half-year results for the period ending July 31, 2026. Adjusting items before tax came to a total charge of GBP 4 million, down from GBP 30 million in the previous half-year, driven mainly by restructuring the operating model at B&Q and the sale of a property in Poland. The group's effective tax rate remains higher than the UK statutory rate because of profits earned in higher tax jurisdictions and no assumed benefit for overseas losses, ADVFN reported. That tax line is worth watching on its own: it is a structural drag, not a one-off charge that disappears next period.
Luceco posted double-digit growth across most major financial indicators in its H1 2026 slides: like-for-like revenue grew 13.9%, and adjusted earnings per share rose 13.6% to 6.7 pence, a performance the company links to the energy transition, the global shift toward sustainable energy sources. The stock slipped anyway, Investing.com noted, a reminder that a good set of numbers and a good share price move are not the same thing.
Also on the tape
The midday London report carried one more item worth flagging for anyone tracking smaller names: 80 Mile agreed indicative terms for an all-share merger with Texas-based Greenland Energy Co.
The day's common thread is the gap between mood and fundamentals. Sentiment was lifted by two things that can turn quickly, a diplomatic opening and a softer oil price, while the slower and harder numbers, French debt, corporate tax rates, rental income and the market's reaction to decent results, kept grinding on underneath. Investors who rallied on Tuesday were, in effect, betting that the first set of forces outlasts the second.
