Key Takeaways
- Central banks are entering a busy period of policy meetings, with markets pricing in a high probability of rate rises for several major economies.
- The Bank of England appears to be the exception, with markets expecting a more cautious path for UK monetary policy.
- Persistent inflation, resilient US growth and stronger labour market data have strengthened the case for near-term action by the Federal Reserve.
- For investors, the key issue is less the next rate move itself and more what central banks signal about the likely path of policy beyond September.
- Higher bond yields and tighter financing conditions could challenge asset valuations, particularly in areas of the market that have benefited from cheap capital.
Central banks are back in focus as investors enter a busy run of September policy meetings. The European Central Bank meets this week, followed by the Bank of England, the US Federal Reserve and the Bank of Japan next week. The timing is important: inflation remains above target in several major economies, while recent data suggest activity, particularly in the US, has remained resilient enough to keep further policy tightening on the table.
Markets are now assigning a high probability to rate rises from the Federal Reserve, the European Central Bank and the Bank of Japan over the coming fortnight. Expectations have been reinforced not only by persistent inflation, but also by recent central bank communication, including comments from Kevin Warsh that emphasised the need to respond to inflation that has remained above target for too long.
The Bank of England is the outlier. Market-implied probabilities point to a less than 10% chance of a rate increase next week, with the first UK rate rise not fully expected until December. That divergence reflects a more finely balanced domestic backdrop and suggests investors should be cautious about assuming a uniform policy path across developed markets.
In the US, the case for near-term action has strengthened over the summer. Growth has remained in reasonable shape, inflationary pressures have persisted and higher commodity prices have complicated the disinflationary trend. The Federal Reserve’s preferred inflation measure, personal consumption expenditures, has been above target since February 2021. Although it has eased from above 4% to 3.7%, it remains uncomfortably high for policymakers.
The latest US labour market data also matter. Friday’s jobs report was stronger than expected and helped offset some of the softer signals seen in recent months. Taken together, a still-healthy labour market and inflation above target give the Fed a rationale to act now, rather than risk allowing inflation expectations to become more entrenched.
For investors, the more important question is not simply whether central banks raise rates in this cycle of meetings, but what they signal about the path beyond it. Bond yields have already moved higher in anticipation of tighter policy, while inflation expectations have been pushed up by renewed commodity price pressure and unresolved geopolitical strains in the Gulf. Central banks therefore face a difficult trade-off: they need to respond credibly to inflation risks, but policy does not need to move far before it becomes restrictive.
That distinction is critical. Raising rates in response to an energy or commodity price shock is unlikely, by itself, to reduce the initial source of inflation. The purpose of tighter policy is instead to prevent second-round effects from feeding through into broader inflation expectations, wages and pricing behaviour. The risk is that central banks overtighten, turning a necessary normalisation of policy into a more damaging restraint on growth and financial conditions.
The economic backdrop still appears capable of absorbing some additional tightening. Recent PMI data remain encouraging and broader activity indicators suggest that major economies are not yet under severe pressure from higher rates. However, markets may be more sensitive than the real economy to a further move higher in yields, particularly after a period in which asset prices have benefited from abundant liquidity and relatively low financing costs.
This is part of a broader normalisation process, but the adjustment is unlikely to be smooth. Higher bond yields can alter discount rates, challenge valuations and expose areas of the market that have relied heavily on cheap capital. That includes parts of the artificial intelligence theme, where a growing share of investment and infrastructure spending is being financed in a higher-rate environment. If the cost of borrowing continues to rise, some assumptions underpinning that theme may come under greater scrutiny.
Overall, the near-term macro backdrop remains constructive, with resilient growth, still-supportive survey data and rate rises that appear largely priced into markets. The main risk lies further out: if inflation proves sticky and central banks feel compelled to tighten beyond current expectations, the consequences for bond markets, risk assets and financing conditions could become more pronounced.
The coming fortnight should therefore provide more than confirmation of individual rate decisions. It should offer important guidance on how central banks are balancing inflation credibility against growth and market stability. The key will be looking beyond headline policy moves and focusing on the language around persistence, optionality and the threshold for further tightening.
