Inflation and Geopolitical Tensions Weigh on Investor Sentiment

It was a difficult week for risk assets as the combination of higher borrowing costs and rising energy prices weighed heavily on investor sentiment. US Treasury yields moved higher across the curve (bond prices move inversely to bond yields) as investors became increasingly concerned that the recent rise in oil prices could reignite inflationary pressures and complicate the outlook for monetary policy. With inflation already proving more persistent than many had hoped, markets began to reassess the possibility that the Federal Reserve (Fed) may be forced to maintain a restrictive stance for longer or potentially tighten policy further should energy-driven price pressures continue to build. The Fed meets later this week.

The backdrop in energy markets remained particularly challenging. Hostilities in the Middle East intensified once again, with attacks escalating around the Strait of Hormuz and extending to key Saudi energy infrastructure. Significant advances by Yemen’s Houthi rebels also tightened their grip on areas surrounding the southern Red Sea, increasing concerns over disruptions through the strategically important Bab al-Mandab Strait, another critical route for global energy shipments. Against this backdrop, fears surrounding the security of global oil supplies intensified, pushing Brent crude briefly above $110 per barrel before some profit-taking on Friday saw prices retrace a portion of those gains. Taken together, the result was a broad sell-off across both global equity markets and government bond markets, as investors grappled with the implications of higher energy costs, rising inflation risks and an increasingly uncertain geopolitical landscape.

Against the challenging backdrop discussed above, losses were widespread across global equity markets last week. In the US, the S&P 500 declined -0.8% (in dollar terms), with small-cap equities faring particularly poorly in what was a shortened trading week due to the Labor Day holiday on Monday. European markets also came under pressure, with the MSCI Europe ex UK Index falling -1.7% (in euro terms) as German and French equities retreated sharply amid concerns that higher energy costs could add further pressure to the region's inflation outlook. The FTSE 100 also fell -1.7%, with strong gains from oil majors insufficient to offset weakness elsewhere. In Asia, the Nikkei 225 declined -1.6% (in yen terms), as a stronger yen and rising expectations for further Bank of Japan policy tightening weighed on growth stocks. Higher oil prices were an added headwind given Japan's heavy reliance on imported energy. Meanwhile, Chinese equities also struggled, with the Shanghai Composite declining -1.1% (in renminbi terms) as weakness was broadly distributed across the market.

The latest UK growth data provided a welcome upside surprise, with the economy expanding by +0.4% in July, extending the run of positive momentum seen in recent months¹. Growth was broad-based, with all three main sectors contributing positively on the month, although services remained the primary driver of activity. The reading also left GDP growth at +0.4% over the three months to July, marking an eighth consecutive rolling three-month period of expansion and suggesting the economy continues to demonstrate reasonable resilience despite higher interest rates and elevated energy costs. Elsewhere, the manufacturing sector delivered a more encouraging performance than has often been the case in recent years. Manufacturing production was +2.6% higher than a year earlier, highlighting an improvement in industrial activity despite a challenging external backdrop².

In August, US consumer price inflation (CPI) remained unchanged at +3.4% year-on-year, indicating that headline inflation stabilised following recent increases in energy costs³. The monthly rise in prices was driven largely by gasoline, with energy-related components making the most significant contribution to the overall increase in the index. Meanwhile, core CPI, which excludes food and energy, rose +2.4% year-on-year, reflecting more modest underlying price pressures.

Meanwhile, the US housing market remained under pressure in August, with existing home sales falling to an annualised rate of 3.98 million units, down -2.0% from July and -1.2% lower than a year earlier⁴. The decline left sales below the four million threshold for the first time since mid-2025, highlighting the continued impact of elevated mortgage rates on housing activity. However, the supply backdrop continued to improve, with housing inventory rising to 1.62 million units, equivalent to 4.9 months of supply, the highest level in over a decade.

The European Central Bank (ECB) delivered a widely anticipated 25 basis point interest rate increase last week, citing the inflationary impact of the ongoing energy shock stemming from the conflict in the Middle East⁵. Policymakers acknowledged that inflation remains well above target and is likely to stay elevated for longer than previously expected, prompting the ECB to take further action despite signs of resilience in the Eurozone economy. The decision was supported by updated forecasts showing inflation averaging +3.0% in 2026, while growth projections were revised modestly higher as economic activity has held up better than anticipated. Subsequent Eurostat revisions were also encouraging, with Eurozone GDP growth for the second quarter revised higher from +0.4% to +0.6% quarter-on-quarter, highlighting the greater-than-expected resilience of economic activity across the region⁶.

Continuing with the GDP theme, revised data from Japan provided a modestly more encouraging picture of economic activity. Second-quarter GDP growth was revised up to +0.4% quarter-on-quarter from the preliminary estimate of +0.3%, marking a third consecutive quarter of expansion⁷. The upward revision was driven primarily by stronger government spending and a smaller-than-expected decline in business investment, suggesting both public and corporate sector activity held up relatively well.

China’s latest trade data highlighted the continued importance of external demand to the country's economic performance. Exports increased by +25.0% year-on-year in August, accelerating from July and reflecting robust global demand for Chinese technology, semiconductor, and AI-related products⁸. The strength of overseas shipments helped push the monthly trade surplus to another elevated level and reinforced the role of exports as a key driver of growth. Imports rose by an even stronger +28.2% year-on-year, marking a sixth consecutive month in which import growth outpaced exports. The increase was supported by continued demand for components and technology-related goods, although imports of some commodities remained constrained by higher prices.

Price data from the country showed a modest firming in inflationary pressures during August. Consumer price inflation (CPI) rose +0.8% year-on-year, up from +0.5% in July, with higher energy costs and seasonal increases in food prices contributing to the acceleration⁹. Outside of food and energy, underlying inflation also strengthened slightly, indicating some improvement in broader pricing conditions. Further up the supply chain, producer price inflation (PPI) increased +3.8% year-on-year, accelerating from +3.5% the previous month and exceeding expectations¹⁰. The rise was driven largely by higher commodity and energy prices, alongside continued demand for technology and manufacturing-related goods. Electronics and machinery prices were among the areas showing particular strength.
