UK inflation rises ahead of central bank rate decision, narrowing the window for holding rates steady

UK inflation rose further ahead of the central bank’s interest rate decision, as energy price shocks continued to feed through to household bills and consumer prices, squeezing the Bank of England’s room to hold rates steady. On September 16, UK Office for National Statistics data showed that the consumer price index (CPI) rose 3.1% year-on-year in August—up from 2.9% in July and the highest since March this year—broadly in line with market expectations. Rising gasoline and diesel prices were the main drivers, while higher household energy bills also contributed to the overall inflation uptick. The Bank of England is set to hold its Monetary Policy Committee (MPC) meeting on Thursday. Markets widely expect the central bank to keep its base rate unchanged at 3.75%. However, if energy-driven inflation persists, markets have begun pricing in a possible rate hike as early as November. Following the release of the inflation data, traders’ probability of a rate hike this week fell—from 35% to 25%—suggesting markets still see a high likelihood of the Bank maintaining a wait-and-see stance in the near term. Meanwhile, rising inflation has also increased fiscal pressure on the government. A sharp rise in UK government bond yields has already been estimated to have halved the government’s fiscal headroom, further constraining policy flexibility ahead of the October budget. Energy prices emerge as the primary driver of inflationary pressures The August acceleration in inflation was largely driven by energy prices. The UK Office for National Statistics noted that surging gasoline and diesel prices were the top contributors to the monthly CPI increase; rising airfare and producer prices also played a role, while higher household energy bills provided additional upward pressure. In early July, the UK energy regulator Ofgem raised the household energy price cap by 13%, directly pushing up electricity and gas prices. At the same time, Brent crude oil recently broke above USD 100 per barrel, and Ofgem has already announced plans to raise the energy price cap again in October—suggesting energy prices may continue to support inflation over the coming months. David Rees, Schroders’ Global Economics Head, said UK inflation could rise further over the coming months, as energy, industrial goods, and food prices continue to pass through to end consumers. According to The Wall Street Journal, markets now expect UK CPI to reach or even exceed 4% early next year—twice the Bank of England’s 2% target. Core inflation remains stable—providing temporary breathing room for the central bank That said, rising headline inflation does not yet signal broad-based price pressures. In August, core inflation—excluding energy and food—held steady at 2.6%, and services inflation—a key focus for the Bank of England—remained unchanged at 3.4%. This suggests current inflationary pressures remain concentrated in external factors such as energy, rather than evolving into broader domestic price pressures. Francesco Pesole, ING strategist, stated there is “still no evidence of inflationary pressures spreading beyond energy,” lending support to dovish voices within the Bank.

Super central bank week—this time is different

Meanwhile, on September 14, Brent crude oil briefly surged above USD 108 per barrel; the US 10-year Treasury yield climbed above 5%, hitting a 17-year high since 2007; spot gold prices fell below USD 4,300 per ounce; and technology stocks came under pressure—the Philadelphia Semiconductor Index dropped 5.9% that day, while the Nasdaq Composite fell 0.56%. The market appears to be replaying last year’s script of ‘safe-haven assets failing’. Yet the underlying drivers have expanded—from fiscal concerns, credit rating risks, and term premium—to oil-driven reflation, a global pivot back toward hawkish monetary policy, AI-related capital demand, surging government bond supply, and the withdrawal of cheap funding. This adds a new dimension to the ‘super central bank week’: when equities, bonds, and gold all come under simultaneous pressure from the same shock, does traditional asset allocation—based on risk diversification across asset classes—still hold? From ‘rate cut countdown’ to ‘renewed hiking’ Just one week earlier, markets had broadly expected the Federal Reserve to hold rates steady at its September meeting. Fresh inflation data and rising oil prices swiftly rewrote market pricing. Goldman Sachs, JPMorgan Chase, HSBC, and Deutsche Bank have all shifted to forecasting a Fed rate hike this week. Stephen Juneau, Senior US Economist at Bank of America, argued that Fed Chair Powell has already narrowed policy space considerably—unless incoming data clearly weakens, it will be difficult for the Fed to avoid hiking. Scott Anderson, Chief US Economist at BMO Capital Markets, noted that the Fed’s anti-inflation credibility is now being tested: if hawkish rhetoric is not matched by action, it could instead steepen the US Treasury yield curve further. Oil prices served as one direct trigger for this shift. On September 15, Brent crude remained near USD 107 per barrel. Saudi Arabia’s east-west cross-country pipeline—which bypasses the Strait of Hormuz and carries around 4 million barrels per day—remains shut following an attack. Central banks cannot produce more oil by raising interest rates—but they must prevent energy shocks from feeding into wages, service prices, and long-term inflation expectations. On September 14, Martins Kazaks, member of the European Central Bank’s Governing Council and Governor of the Bank of Latvia, stated that the case for further tightening is strengthening—and that 2.5% should not be viewed as a ceiling for euro area interest rates. On September 17, the Bank of England’s policy meeting is still widely expected to leave its base rate unchanged at 3.75%. Yet the market-implied probability of a 25-basis-point hike this month has risen to around 30%. Both Goldman Sachs and Citigroup have revised their forecasts—from expecting no UK rate hikes through 2026, to now anticipating a hike before year-end. The Bank of Japan is also expected by markets to raise rates by 25 basis points. Japan’s prolonged low-interest-rate environment has sustained a massive yen-funded carry trade ecosystem. Now, Japan’s 10-year government bond yield has surged above 3%, reaching a 30-year high. While the Fed primarily influences dollar funding costs and global asset pricing benchmarks, the BOJ may alter the marginal scale of the world’s low-cost funding pool. Rising interest rates are compounding massive funding demands. In August, the US Treasury estimated net privately held, non-marketable debt financing needs at USD 739 billion for Q3 and USD 628 billion for Q4—totaling approximately USD 1.37 trillion across both quarters. Starting in September, the US Treasury will also double the single-operation size limit for liquidity-support repo operations on nominal coupon-bearing Treasuries—raising it from USD 2 billion to at least USD 4 billion—for two maturity buckets: 10–20 years and 20–30 years.

Bank of England to Hold Rates Despite Energy Shock Fueling Hike Speculation

The Bank of England is set to maintain interest rates despite surging energy prices linked to the Iran conflict. Rising natural gas and crude costs may force a rate hike in November as inflation exceeds the 2% target.
