What it means
The G-20 was formed in 1999 after a series of financial crises in emerging markets, as a meeting place for finance ministers and central bank governors. It was raised to the level of leaders' summits during the global financial crisis of 2008, when it became clear that major problems needed coordination well beyond the traditional wealthy-country groups.
Today it covers the large majority of the world's economic output and population, which is why its agreements carry real weight in boardrooms. The group does not have a permanent headquarters or staff.
A different member holds the rotating presidency each year, sets the agenda and hosts the main summit, and ministers and officials meet throughout the year in working groups. International bodies such as the International Monetary Fund, the World Bank and the Financial Stability Board contribute analysis.
Its decisions come as communiques, action plans and commitments rather than treaties. Even so, they carry weight because they reflect political agreement among the largest economies, and they often feed directly into national laws and regulators.
Examples of areas influenced by the group include bank capital standards, tax transparency and coordination of stimulus or crisis responses. For finance professionals, the G-20 matters because its agreements can change the rules businesses operate under.
A new approach to international corporate taxation, for example, or tighter standards for banks, will be discussed at this level before it shows up in local legislation. Watching the group's agenda gives early warning of regulatory trends, and the final communique is usually worth reading for the topics it names.
The nuance is that the group works by consensus, so progress can be slow and the agreements are sometimes watered down. Each country must still act through its own parliament or regulator, and political disagreements between members can stall action.
In practice
Real-world examples.
Example
A multinational group's tax director follows G-20 discussions on how profits should be taxed across borders. She uses the early signals to model the effect on the company's effective tax rate and prepares the board for likely changes. Months later, new national rules follow the broad direction that was agreed.
Example
A bank's risk officer tracks G-20 agreements on capital and liquidity standards. These agreements were later turned into national regulations that required the bank to hold more high-quality capital. The treasury team planned its funding mix accordingly.
Example
An export company sees G-20 leaders commit to resisting new trade barriers during a period of economic stress. The finance manager treats the commitment as a modest positive for planning, but still keeps contingency budgets for tariffs. She reviews the position at each year's summit, and she tells the sales team to avoid quoting fixed prices for longer than twelve months.
Case study
Seen in the real world.
Zephyr Components is an illustrative, fictional manufacturer that sells to customers in more than 30 countries. Its chief financial officer noticed that G-20 communiques were repeatedly mentioning a new framework for how companies are taxed when they sell across borders.
She asked the tax team to model three scenarios: no change, a moderate change and a larger change, using the company's actual sales by country. The results showed that the larger scenario could raise the group tax bill by several million dollars a year.
In the illustrative outcome, the board decided to hold extra cash against the risk and to review its supply chain locations. When national rules were eventually introduced, the company was already prepared, and the finance team had no need to rush a response. The tax director later presented the exercise to other divisions as a model for planning.
Watch out
Common mistakes.
- Assuming that G-20 agreements are laws, when they are political commitments that each country must put into effect itself.
- Thinking the G-20 is a formal organisation with offices and staff, when it works through rotating presidencies and shared working groups.
- Ignoring its statements as talk, when many of them give early warning of rules that later affect banks, taxes and trade.
Questions
People also ask.
How many members does the G-20 have?
It has 19 countries, plus the European Union and the African Union, so the membership is in effect larger than the name suggests.
How is the G-20 different from the G-7?
The G-7 is a smaller group of advanced economies, while the G-20 includes major emerging economies and represents a much larger share of the world economy.
Who chairs the G-20?
The presidency rotates each year among members, and the country holding it hosts the leaders' summit and sets the priorities. A small group of past, present and future hosts works together to keep the agenda consistent from one year to the next.
