AI Search: Midterms Loom as AI Debate, China Data, and Oil Tension Split Markets
Top story
The dominant thread across global markets is a widening divergence inside the technology trade itself. The AI spending debate continues to pressure US tech names, while the same AI buildout is producing the strongest October export surge in decades for South Korea. Markets are now treating the US midterm elections as the next major swing factor, with investors treading carefully into the vote. Layered on top is a stronger US jobs picture that keeps the Federal Reserve open to further hikes, and an unresolved Iran standoff alongside broader Middle East tensions holding oil near six-month highs. The result is a market that is long one theme in some regions and short it in others, with no single narrative able to set direction.
Asia Pacific
China's official October manufacturing PMI fell back into contraction, and the reading weighed on Chinese equities and the currency. The soft start-of-quarter momentum undercut the case that the factory sector had found a durable floor.
South Korea presents the sharpest contrast. October exports surged at the strongest pace in decades on the AI chip boom, yet the won weakened sharply, with the dollar-won rate nearing the 1,200 level in market commentary. That combination — booming export volumes and a stressed currency — adds a new pressure point to an export-led economy even as semiconductor inflows remain strong. Korean equities traded lower on the currency development.
Japan's trend inflation gauge accelerated to a three-year high in September, strengthening the case for further Bank of Japan tightening. Japanese equities rose on the news, with the yen showing firm support.
Elsewhere in the region, Thailand reported stronger-than-expected trade momentum, with border and transit trade topping one trillion baht in the first nine months of the year, lifting Thai assets. Indonesia traded lower after its market regulator said it is studying compensation for investors affected by the DSSA, BREN, and CUAN stock cases. Vietnam's government set an ambitious fourth-quarter growth target of 12.5% to reach 10% full-year expansion, backed by measures to ease credit bottlenecks and project licensing, supporting Vietnamese assets.
Europe
France became the region's problem child. The economy unexpectedly contracted in the third quarter while October harmonized inflation accelerated, a stagflationary mix made worse by a negative outlook from Fitch and borrowing costs at multi-decade highs. French and broader eurozone equities fell on the combination. Youth-led cost-of-living protests across France, Germany, and Italy added a political undercurrent, though so far without a clear market catalyst.
Spain moved in the opposite direction. Third-quarter GDP growth came in resilient and October inflation held sticky, lifting Spanish assets and supporting Spanish duration. The France-Spain split is a reminder that eurozone macro risk is currently country-specific rather than bloc-wide, even as the French drag pulled the broader eurozone complex lower.
North America
US stocks treaded carefully into the midterms, with tech still under pressure from the AI spending debate. The stronger jobs picture complicates the picture for rate-sensitive sectors by keeping further Fed hikes on the table.
Canada fell after its steepest daily drop since June. Gold's slide hit a metals-heavy market despite flat GDP, and the federal government's decision to delay tougher passenger-vehicle emissions standards until 2029 — pushing back the earlier 2027 timetable — offered some relief to auto-exposed names.
Mexico benefited from third-quarter growth beating forecasts on stronger investment, even as the budget deficit widened. Mexican equities rose and the peso stabilized.
Latin America and India
Argentina told a two-sided story. The central bank's October dollar purchases lifted cumulative 2026 buying to a level keeping reserves above the IMF's implied target, a material reserve update that supported Argentine assets. At the same time, month-end market stress deepened: the sovereign risk premium rose and dollar bonds weakened, with rising country risk pressuring the complex. The tension between improving reserves and elevated sovereign stress remains unresolved in the price action.
Brazil faced a downgrade cycle. A major local bank sharply cut its 2027 growth forecast and lifted its inflation outlook, while expecting the central bank to keep rates higher for longer. Brazilian equities fell on the combination of slower growth and stickier inflation.
India's Finance Ministry reported a sharp acceleration in bank lending and commercial-sector financing in the fiscal year so far, with bank credit growth running hot as of the end of September. Indian assets rose on the credit momentum.
Market reaction
Direction was broadly divergent. Equities split between AI-driven strength in Korean exports and weakness in Chinese factory data, with US tech and eurozone names lower and Spanish, Mexican, Indian, and Thai assets higher. Gold's slide weighed on precious metals and metals-levered markets, while oil held near six-month highs on Middle East tensions. Sovereign bonds told a mixed story: Argentine dollar bonds weakened on rising country risk while Spanish and US duration assets firmed. Currencies split between a sharply weaker won and peso stabilization alongside firm yen support.
Policy / macro
Central bank activity was active on both sides. Egypt's central bank delivered a surprise rate hike, its first increase since early 2024. Japan's trend inflation at a three-year high strengthens the case for further Bank of Japan tightening. Brazil's central bank is expected to keep rates higher for longer per local bank commentary. The stronger US jobs picture keeps the Federal Reserve open to further hikes. Fiscal and regulatory developments also featured: Canada's emissions-standards delay, Vietnam's growth-target measures, and Indonesia's compensation study.
