Energy Prices Climb Sharply Amid Renewed Middle East Conflict

Oil prices advanced strongly last week as escalating hostilities around the Strait of Hormuz and across the Iranian mainland fuelled concerns over the security of one of the world's most critical energy transit routes. After a month of relative calm, attacks resumed once again, with both sides launching fresh strikes and reaffirming hardened positions. With repeated rounds of negotiations failing to produce a lasting breakthrough and tensions continuing to escalate, the prospect of a meaningful resolution appears increasingly remote. Against this backdrop, Brent crude surged +8.0%, ending the week above $96 per barrel and moving back towards the psychologically important $100 threshold. The renewed rise in oil prices also contributed to higher sovereign bond yields, as investors grew increasingly concerned that elevated energy costs could complicate the inflation outlook and force central banks to maintain a restrictive policy stance for longer than previously anticipated.

With energy prices moving sharply higher, the energy sector was one of the clear winners last week, emerging as the strongest-performing area of the global equity market. At the headline level, however, broader market performance was more subdued. The S&P 500 finished the week broadly unchanged (in dollar terms) as investors balanced growing concerns over developments in the Middle East against another round of encouraging corporate earnings from certain names related to the artificial intelligence (AI) value chain, where demand continues to accelerate. Semiconductor designer Broadcom was one such name, delivering better-than-expected results and providing an upbeat outlook that reinforced confidence in the long-term growth trajectory of AI-related spending and infrastructure investment¹. Elsewhere, equity markets were largely on the backfoot. European equities moved lower as renewed inflation concerns linked to higher energy prices pushed government bond yields higher, creating a more challenging backdrop for risk assets. The FTSE 100 was broadly flat over the week, with strong gains from energy majors such as BP and Shell largely offsetting weakness across other areas of the market. In Asia, equities also came under pressure. A sharp strengthening of the yen during the middle of the week weighed on sentiment in Japan, contributing to a -2.1% decline in the Nikkei 225 (in local currency terms), while the Shanghai Composite shed -0.6% (in renminbi) as investors continued to assess the outlook for Chinese growth.

The latest Bank of England Money and Credit data pointed to a moderation in housing market activity during July. Net mortgage borrowing fell back to £4.3bn, down from £7.7bn in June and below the recent six-month average, while mortgage approvals for house purchases declined to 56,100². The figures suggest that higher mortgage rates and ongoing economic uncertainty are continuing to weigh on borrower appetite. In contrast, consumer credit borrowing edged up to £2.0bn from £1.9bn, driven by an increase in personal loans and other forms of unsecured lending.

Separate data from Nationwide highlighted the subdued nature of the UK housing market in August. House prices increased by +0.2% month-on-month, while annual growth edged up to +1.6% from +1.4% in July³. Nationwide’s data highlighted a continued regional divide, with Northern Ireland comfortably outperforming the UK average, while parts of Southern England, particularly the South East, remained among the weakest-performing areas. More broadly, northern regions, Scotland and Northern Ireland have continued to lead house price growth, supported by stronger affordability and underlying demand. The average house price in the UK stood at £275,465 last month, roughly £1,000 lower than back in July.

August's US labour market data provided a meaningful upside surprise, easing concerns that hiring momentum was fading too rapidly. Non-farm payrolls increased by 162,000, comfortably ahead of expectations for a much more modest 65,000 gain and well above the average monthly increase recorded over the past year⁴. The strength was broadbased, with notable contributions from hospitality, local government education and manufacturing, while upward revisions to the previous two months added a further layer of encouragement. Meanwhile, the unemployment rate remained unchanged at 4.1%, wage growth continued cool with average earnings rising +3.1% year-over-year.

The latest ISM surveys for August painted a steady picture of the US economy. The ISM Manufacturing PMI rose to 54.6, indicating continued expansion in the factory sector, but the reading came in slightly below expectations⁵. In contrast, the ISM Services PMI increased to 55.4, surpassing forecasts and highlighting the ongoing strength of the much larger services sector⁶. Both readings remained comfortably above the 50.0 threshold that separates expansion from contraction. While manufacturing activity continued to grow at a healthy pace, momentum appeared somewhat less robust than investors had hoped. By comparison, the services sector benefitted from stronger business activity and demand, helping to offset concerns elsewhere in the economy.

European inflation data for August highlighted the extent to which rising energy costs continue to influence the economic backdrop. Headline Eurozone CPI accelerated to +3.3%⁷, up from +2.9% in August, while producer prices increased by +5.8% year-on-year⁸, pointing to renewed cost pressures further up the supply chain. The rise in both measures was largely driven by higher energy prices as tensions in the Middle East continued to feed through into fuel, utility and industrial input costs.

Consumer spending across the Eurozone remains somewhat mixed. While retail sales were higher than a year ago in July, activity softened compared with June, suggesting households are becoming more cautious as higher energy prices and a more uncertain economic backdrop weigh on confidence⁹. The labour market, meanwhile, remains relatively stable. The unemployment rate held at 6.4% in July, unchanged from the previous month, highlighting continued resilience in employment conditions despite softer economic momentum across parts of the region¹⁰.

Keeping with the retail sales theme, the latest data from Japan were considerably more encouraging. Retail sales increased by +4.0% year-on-year in July, rebounding sharply from June and recording the strongest growth in several months¹¹. The increase was broad-based, with particularly strong contributions from automobile sales, alongside continued growth in clothing and personal goods. Sales of food and beverages also improved, helping to support the overall reading.

China's latest RatingDog PMI surveys provided a more encouraging update in August, with both manufacturing and services activity strengthening. The Services PMI rose to 51.4, signalling a modest acceleration in business activity, supported by firmer domestic demand, improving new orders and continued growth in employment¹². Business confidence also improved, although cost pressures remained evident. The Manufacturing PMI improved to 51.5, moving further into expansionary territory and pointing to a recovery in factory activity¹³. The underlying detail was broadly constructive, with output, new orders and export demand all improving during the month, while purchasing activity also strengthened. Rising input costs remained a headwind, reflecting higher energy and raw material prices.
