Bank of England Chief Economist Huw Pill has reignited the debate over a potential rate hike in September, arguing for a quarter-point increase to 4%. His comments come as the UK bond market continues to show elevated yields across the curve, with the 10-year gilt closing at 5.1345% on Friday, down from a peak of 5.2326% earlier in the week.
Pill, speaking in Edinburgh, emphasized the risks of waiting too long to act. "If you follow a 'wait-and-see' approach and then do not 'see', all you have done is waited," he said, warning that rising energy costs could seep into wages and broader prices. He argued that a prompt move could reduce the need for more aggressive action later, while stressing that one increase would not necessarily start a prolonged tightening cycle.
Despite Pill's advocacy, market pricing suggests a September move is unlikely. According to Reuters, rate futures on Thursday implied only a 15% chance of a hike this month, while the probability for November exceeded 70%. The Bank's Monetary Policy Committee remains divided, with July's vote showing six members favoring a hold and three, including Pill, Megan Greene, and Catherine Mann, voting for an increase.
The bond market's signals are mixed. Two-year gilt yields rose 12 basis points last week to 4.5335%, while 10-year yields added 5.7 basis points. In contrast, 30-year yields slipped 2.3 basis points to 5.774%, flattening the curve. These levels, well above the current Bank Rate of 3.75%, reflect not only expected policy rates but also inflation, term, and fiscal risk premiums.
Sterling showed little reaction, ending near 1.3517 against the dollar, about 0.6% below its late-August level. The FTSE 100 finished at 10,831.10, nearly unchanged over the same period. The relatively calm market response to Pill's speech suggests investors are not bracing for an imminent move.
Looking ahead, key data releases will shape the decision. July GDP figures, due September 11, are expected to show 0.4% growth in the three months through June. August inflation data follows on September 16, with July CPI already rising to 2.9% from 2.6%, while services inflation eased to 3.4%. A soft GDP reading and cooler inflation would bolster the case for holding rates, while a hot CPI print could make Pill's insurance argument harder to dismiss.
The implications for borrowing costs are significant. Elevated gilt yields translate into higher mortgage rates and corporate borrowing costs, weighing on household finances and business investment. Long-duration equities, particularly in growth sectors, remain sensitive to the 10-year yield as a discount rate.
Geopolitical risks, particularly energy supply disruptions, could complicate the outlook. Another energy shock would likely push inflation higher before weak demand becomes visible, potentially leaving a pre-emptive hike looking late. For now, the bond market's message is split: September remains a minority bet, but Britain's wider financing bill is already anything but cheap.
