What it means
Before the treaty, European countries cooperated through the European Communities. The agreement signed in the Dutch city of Maastricht in 1992 created the European Union, which added shared policies on foreign affairs, security and justice alongside the economic cooperation that already existed.
It also committed members to build an economic and monetary union. The monetary part was the key one for finance.
It established a timetable and conditions for a single currency, run by a common central bank. Countries wanting to join had to show that their economies were sufficiently similar for one interest rate to suit them all.
Those conditions are the convergence criteria. They cover inflation, which had to be close to that of the best-performing members, government deficits, which were capped at 3% of gross domestic product (GDP, the total value of what an economy produces in a year), and government debt, capped at 60% of GDP.
Long-term interest rates also had to be close to those of the best performers, and the exchange rate had to stay stable within a set band for at least two years. The rules matter to businesses because they shaped the macroeconomic environment of the euro area.
Companies trading across borders benefit from the removal of currency risk between members, and from prices that are easier to compare. At the same time, countries gave up control over their own interest rates and exchange rates.
A common criticism is that the deficit and debt limits were not always followed and that a single currency without a full fiscal union leaves weaker economies exposed in a crisis. These debates shaped later reforms, and the treaty has since been amended and updated several times.
In practice
Real-world examples.
Example
A treasurer at a German exporter notes that selling to customers in other euro area countries carries no exchange rate risk. She no longer pays to hedge those sales, saving the company tens of thousands of dollars a year.
Example
A bond investor in Canada compares the debt and deficit ratios of several European governments against the benchmark levels from the treaty. She uses the comparison as one input when deciding which government bonds to hold.
Example
A multinational retailer plans pricing across Europe. Because shoppers can now compare euro prices across borders easily, its pricing team narrows the differences between countries to avoid customers buying from cheaper neighbours.
Formula
Calculation
Deficit ratio = Government deficit / GDP x 100%, and Debt ratio = Government debt / GDP x 100%
Suppose a country has a GDP of $2,400 billion, a government deficit of $60 billion and government debt of $1,560 billion. Deficit ratio = 60 / 2,400 = 0.025, or 2.5%, which is under the 3% limit, so it passes. Debt ratio = 1,560 / 2,400 = 0.65, or 65%, which is above the 60% limit, so it fails that test. Although the debt ratio is too high, the criteria allow for a debt ratio that is falling at a satisfactory pace.Case study
Seen in the real world.
Aldermoor is an illustrative, fictional country preparing to join a currency union. Its finance ministry measured itself against the Maastricht-style tests. Inflation was close to the benchmark, but the deficit stood at 4.5% of GDP and debt at 70%.
The government spent three years cutting spending and raising taxes to bring the deficit to 2.8%, and it showed debt falling each year. Businesses faced a tougher domestic climate during the squeeze, but exporters welcomed the prospect of dropping currency hedging costs. In this fictional story, entry to the union was approved, and the lesson was that meeting entry conditions required real sacrifices.
The finance ministry also explained the benefits to local companies. Lower interest rates, stable prices and the end of currency conversion costs were expected to lift investment, and the fictional government used these gains to defend the budget cuts to the public.
Watch out
Common mistakes.
- Believing that the treaty itself created the euro notes and coins, when it set the framework and the conditions, and the currency was introduced later.
- Assuming the criteria are only about debt, when they cover inflation, deficits, interest rates and exchange rate stability as well.
- Treating the deficit and debt limits as unbreakable, when in practice several countries have exceeded them.
Questions
People also ask.
When did the treaty take effect?
It was signed in 1992 and entered into force in 1993.
What are the convergence criteria?
They are the tests on inflation, government deficits, government debt, long-term interest rates and exchange rate stability that countries had to meet to adopt the euro, designed to make sure that economies joining the currency were broadly compatible.
Why do the deficit and debt limits matter to businesses?
They influence government borrowing costs, tax policy and the stability of the economy in which companies operate, all of which feed into the cost of capital.
