Britain's Euro Convergence: A Crucial Test for EU Entry

Strategic Insights -

The debate over Britain's potential membership in the eurozone has reignited as euro notes and coins prepare to arrive on British soil. A key test for Britain's entry into the eurozone is whether its economy has converged sufficiently with the eurozone to prosper when shackled to a single currency. Over the past five years, the British economy has faced numerous shocks, including the Asian financial crisis, a tripling of oil prices, and the September 11 attacks. Despite these challenges, Britain's growth rate has remained closer to the eurozone's than the US, with the economy growing at a rate of around 2.5% per year, in line with the European Central Bank's (ECB) working assumption.

Key Takeaways:

  • The British economy has been more resilient to external shocks than the US economy, with growth rates closer to the eurozone's than the American hare.
  • The Treasury's estimate of Britain's long-term trend rate of growth is around 2.5%, in line with the ECB's working assumption of trend growth in the eurozone of 2 to 2.5%.
  • The output gap in the eurozone is generally thought to be greater than in Britain, however estimates are unreliable.
  • The Bank of England has cut interest rates faster and further than the ECB in response to economic shocks.
  • Structural differences, such as high levels of owner-occupation and mortgage debt, high levels of borrowing at variable interest rates, and a more developed stock market, set Britain apart from other eurozone economies.
  • The Oxford Economic Forecasting argued that adjustment to economic shocks would be more protracted and painful inside the eurozone than outside due to the loss of monetary independence.

Statistics:

  • The gap between the ECB's main interest rate and the Bank of England's is just three-quarters of a percentage point.
  • Britain's Treasury estimate of its long-term trend rate of growth is around 2.5%.
  • The European Central Bank's working assumption of trend growth in the eurozone is 2 to 2.5%.
  • The Bank of England has cut interest rates faster and further than the ECB this year.
