Meetings were held at the Federal Reserve, Bank of England and Bank of Japan this week against a backdrop of surging oil prices and renewed inflation concerns. The result was a volatile few days for bond markets. Government borrowing costs climbed to levels not seen since before the global financial crisis, as investors reassessed how long interest rates might remain high.
Concerns over disruptions to Saudi Arabian energy infrastructure and uncertainty around key Middle Eastern shipping routes pushed Brent crude prices to nearly $110 a barrel, while European natural gas prices reached their highest level since 2022. For central bankers, this was an unwelcome development, threatening to keep inflation above target for longer.
Bond investors reacted by pushing the US ten-year Treasury yield above five per cent for the first time since 2007. UK Gilt yields and German government bond yields both reached their highest level since the financial crisis.
The week’s main event came on Wednesday when the Fed raised interest rates by 0.25 percentage points. The move was widely expected. The bigger story was the Fed’s warning that inflation remained a concern and that policy might need to stay restrictive for longer than investors had anticipated. Markets moved to price in the possibility of further tightening over the coming year.
At the same time, economic data continued to show remarkable resilience. US retail sales rose by 1.2 per cent, comfortably ahead of expectations, while jobless claims fell to just 196,000. The world’s largest economy is still growing despite higher borrowing costs.
Central banks remain focused on inflation rather than growth concerns
The Fed was not alone. The Bank of England left rates unchanged but adjusted elements of its strategy, helping gilts recover after their earlier sell-off. Meanwhile, the Bank of Japan raised rates to 1.25 per cent, its highest policy rate since 1995. Central banks remain focused on inflation rather than growth concerns.
Equity investors largely took their cue from bonds and oil. Rising yields weighed on sentiment during the first half of the week. The S&P 500 fell and semiconductor stocks suffered their sharpest one-day decline since July.
Sentiment turned by Thursday. Oil prices retreated as Saudi supply disruptions appeared less severe than initially feared and Libyan production began recovering. Diplomatic efforts also reduced concerns about further disruption to shipping routes. By Friday morning, Brent crude had fallen back to around $103 a barrel, easing inflation worries and helping bond yields retreat.
Investors are increasingly accepting a higher-for-longer interest rate environment
Equities rallied by Thursday too. The S&P 500 gained 1.14 per cent, the Nasdaq rose by 1.69 per cent and semiconductor shares jumped by more than three per cent during Thursday’s session.
By the end of the week, market prices were reflecting a much greater chance that interest rates would remain high well into 2027. That is a notable shift from the optimism seen earlier this year.
Economic growth continues to hold up. But with inflation concerns lingering, bond yields near multi-decade highs and cautious central banks, investors are increasingly accepting a higher-for-longer interest rate environment.1
Past performance is not a reliable indicator of future results.
