Central banks have turned back to hiking, following two years of (nearly) synchronised rate cuts. 
In this episode, Paul is joined by Jon Butcher, Felix Feather and Sree Kochugovindan from the Global Macro Research team to discuss this shift back towards monetary tightening.

In the wake of major decisions from the US Federal Reserve (Fed), Bank of England (BoE), European Central Bank (ECB) and Bank of Japan (BOJ), they discuss whether policymakers are delivering a small number of ‘risk management’ rate hikes, or embarking on a sustained cycle of raising borrowing costs.

The team examine the economic forces driving these rate hikes, including high energy prices, stronger growth, and rising estimates of ‘neutral’ interest rates. The team also considers the growing influence of politics on central banking.

Some highlights:
  • Why the Fed has surprised many observers by raising rates despite expectations for cuts earlier this year. 
  • How higher energy prices are prompting central bankers to focus on preventing inflation from becoming embedded in wages and broader prices. 
  • Why the Fed, BoJ, BoE and ECB are not yet finished raising interest rates.
  • What is happening to central-bank balance sheets and why these largely unseen decisions matter for bond markets and government finances. 
  • Whether politics is becoming an increasingly important influence on monetary policy in the US, Europe and Japan. 
  • The debate over the ‘neutral’ interest rate and why stronger demand for investment, including spending linked to artificial intelligence, could keep borrowing costs higher over the long term.
