What it means
The group came out of informal meetings in the early 1970s, after the old system of fixed exchange rates broke down and the leading economies needed a way to talk privately about currencies, inflation and growth. The five participants were the largest advanced economies at the time.
Their finance ministers and central bank governors met without large staffs or public fanfare, which allowed them to speak frankly about sensitive subjects such as exchange rates. The G-5's most famous moment was the Plaza Accord, agreed in 1985 at the Plaza Hotel in New York.
At the time the US dollar had risen sharply, which hurt American exporters and increased pressure for protectionist trade measures. The five countries announced that they would act together, including through currency market intervention, to encourage a fall in the dollar.
The dollar did decline in the following months and years, and the episode is often cited as a rare example of successful coordinated currency action. It also showed how policy announcements by a small group can influence exchange rates, and how governments can use their combined weight in markets, and for years afterwards currency traders reacted strongly to hints of similar agreements.
Some economists argue that the shift also contributed to economic changes in Japan in the late 1980s, although historians still debate how large that effect was. Over time, the group's role was taken over by larger bodies.
Canada and Italy joined the discussions to form the G-7, and Russia later joined for political talks, while the G-20 became the main forum for economic coordination. The name G-5 is now mostly historical, though it is still used when discussing the Plaza Accord.
The nuance is that the term can cause confusion, since there are other groups with a similar name, such as the BRICS group of emerging economies or the G5 Sahel in Africa. In finance, G-5 normally refers to the five advanced economies behind the Plaza Accord.
In practice
Real-world examples.
Example
A US machinery exporter in the mid-1980s struggled to compete because a strong dollar made its products expensive overseas. After the countries agreed to push the dollar down, its export prices became more competitive and orders recovered. The finance team had to restate its currency forecasts.
Example
A Japanese carmaker saw the yen rise sharply after the Plaza Accord, which cut the value of its overseas earnings in yen terms. Its treasury responded by shifting some production abroad and increasing currency hedging. The change shaped its global manufacturing strategy.
Example
A modern business school lecturer uses the Plaza Accord as a case study in currency policy. Students calculate how a 20% fall in the dollar would change the price of a $100 export in the buyer's currency. The class then discusses why coordinated action works better than action by one country.
Case study
Seen in the real world.
Atlas Machine Works is an illustrative, fictional American exporter of industrial pumps. In the story, its board faced falling overseas orders because a strong dollar made its equipment 25% more expensive for foreign buyers than the year before.
The finance director studied the policy discussions among the major industrial economies and recognised that a coordinated move to weaken the dollar was possible. She modelled three exchange rate scenarios and showed that a 15% fall in the dollar would restore most of the lost competitiveness.
In this illustrative outcome, the dollar declined, orders recovered and the company's margins improved. The board then decided to hold a standing exchange rate review each quarter, so the business would never again rely on luck. The treasurer also began pricing large export quotes in more than one currency.
Watch out
Common mistakes.
- Confusing the G-5 with the BRICS, which is a different group of emerging economies formed much later.
- Thinking the G-5 still meets in the same form, when its role has been taken over by the G-7 and G-20.
- Assuming the Plaza Accord was a treaty, when it was a political agreement to act together.
Questions
People also ask.
Which countries made up the G-5?
France, West Germany, Japan, the United Kingdom and the United States, which were then the largest industrial economies outside the Soviet bloc.
What was the Plaza Accord?
It was a 1985 agreement among the G-5 nations to encourage a fall in the value of the US dollar through coordinated action. The name comes from the Plaza Hotel in New York, where the finance ministers met.
Why does the G-5 still matter?
It is a classic example of how coordinated government action can move currency markets, and it is often used in teaching about exchange rate policy. It also reminds treasurers that a currency can move sharply because of a policy decision rather than because of trade flows.
