The Risks of Joining the European Single Currency

Strategic Insights

— 1 min read

Entering the European single currency would pose significant risks to the UK economy, despite its potential benefits. The government's assessment of five economic tests, designed to ensure sustainable convergence, is overly optimistic. The UK's high short-term interest rates and exchange rate make it difficult to meet these tests, and the required fiscal tightening would be unpopular and potentially destabilizing.

Key Takeaways:

  • The UK's rate of inflation is not significantly different from the euro-zone's average, but short-term interest rates are 2.75 percentage points higher, and the real exchange rate is 20% above its average of the past 25 years.
  • The UK might be able to lower interest rates to push the exchange rate down, but this would threaten economic instability and a decline in competitiveness.
  • The government would need to introduce a large fiscal tightening of around £20bn (2.5% of GDP) to offset the demand- and inflation-boosting impact of lower interest rates and depreciation.
  • This fiscal tightening would also generate an unnecessarily large fiscal surplus, making it unpopular and potentially destabilizing.
  • The UK's financial structure is more interest-rate sensitive than other euro-zone countries, making it vulnerable to a domestically inappropriate monetary policy.
  • The exchange rate stability provided by the euro might come at the cost of a monetary policy that destabilizes the economy as a whole.
  • The European Central Bank is not sufficiently transparent and accountable, and the stability and growth pact lacks a sensible marriage between member state discipline and flexibility.

Statistics:

  • UK inflation rate: 1.5% (April 1999)
  • Euro-zone inflation rate: 1.1% (April 1999)
  • Short-term interest rates: UK 6.75%, euro-zone 4%
  • Real exchange rate: UK 20% above its average of the past 25 years
  • UK GDP on which fiscal tightening is calculated: £20bn
