Market Perspectives: Second guessing the central banks

Central banks may tighten further to contain persistent inflation, but the greater investment risk lies in how far policy extends beyond the rate decisions already priced in.

• The European Central Bank, Bank of England, Federal Reserve and Bank of Japan are scheduled to meet over a two-week period in September, while markets assign high probabilities to rate rises from the Fed, ECB and BoJ.
• The Bank of England is the outlier, with markets pricing less than a 10% chance of a rate increase the following week and not fully expecting the first UK rise until December.
• US personal consumption expenditures inflation has eased from above 4% to 3.7% but has remained above the Federal Reserve’s target since February 2021; stronger-than-expected labour-market data reinforce the case for near-term action.
• Rate rises cannot directly remove an energy or commodity shock, but tighter policy can limit second-round effects through inflation expectations, wages and pricing behaviour; overtightening could instead damage growth and financial conditions.
• Recent PMI and activity indicators remain resilient, yet higher bond yields could challenge discount rates and valuations, particularly in areas such as artificial intelligence where investment and infrastructure spending increasingly rely on borrowing.

Takeaway: Investors should focus less on the immediate rate decisions, which are largely priced in, and more on central-bank language about inflation persistence, policy optionality and the threshold for further tightening; sticky inflation could create a larger subsequent shock for bonds, risk assets and financing conditions.
