You may have seen the letters BRICS in the news and wondered what they stand for. BRICS is a group of major emerging economies that work together on trade, finance, and global politics. It started small, with just four countries, and it has grown into a club that now speaks for nearly half of the world’s people. Here is what it is, what it actually does, and why it matters, in plain language.
What the Letters Mean
BRICS is an acronym made from the first letters of its founding members: Brazil, Russia, India, China, and South Africa. The name began as an idea among economists in 2001, who noticed that these four large countries — Brazil, Russia, India, and China — were growing fast and would become major economic powers. The first three letters, BRIC, came from that observation. South Africa joined in 2010, adding the S, and the group has kept the name ever since.
The idea was simple. These countries were big and growing, but the rules of the world economy were mostly written by a smaller group of rich Western countries. By working together, the BRICS countries hoped to have a louder voice in institutions like the International Monetary Fund and the World Bank, and to build some of their own.
Who Is in BRICS Today
The group expanded in 2024, when Egypt, Ethiopia, Iran, and the United Arab Emirates joined as full members. Indonesia became a full member in January 2025. Argentina was invited too, but its new government declined the invitation. Saudi Arabia was also invited and has taken part in meetings, though it has not formally confirmed full membership.
That brings the group to ten full members, with several other countries taking part as partners. Together, the members account for roughly 45 percent of the world’s population and more than a third of global economic output. China and India alone make up more than a third of humanity, which is one reason the group carries weight.
What BRICS Actually Does
BRICS is not a military alliance, and it is not a trade bloc with a single set of rules like the European Union. It is looser than that: a forum where leaders meet, make joint statements, and launch shared projects. The most important of those projects is a bank.
In 2014 the members set up the New Development Bank, based in Shanghai, to lend money for roads, railways, clean energy, and other infrastructure in developing countries. It was designed as an alternative to the World Bank and the International Monetary Fund, where lending decisions have long been dominated by Western countries. The bank has since approved billions of dollars in loans, mostly for projects in its own member countries.
The group also created a financial safety net called the Contingent Reserve Arrangement, a pool of about 100 billion dollars that members can draw on if they run into a currency crisis. And at their yearly summits, the leaders discuss everything from trade and energy to reforming the United Nations.
One topic that gets the most attention is the role of the US dollar. Many BRICS members would like more of their trade to be settled in their own currencies rather than dollars. Our earlier explainer on why oil prices rise and fall looks at how much of the global energy trade is still priced in dollars. So far, the group has made only slow progress on this: the dollar remains the world’s main currency for trade and reserves, and the members disagree among themselves about how far and how fast to move.
Why It Matters
BRICS matters for three reasons. First, size. A group that holds nearly half the world’s people and a large share of its oil, gas, and food production cannot be ignored when global rules are written.
Second, it gives developing countries a second option. For decades, a country that needed a loan for a dam or a railway usually went to the World Bank or the International Monetary Fund, which often came with strict conditions. The New Development Bank offers another source of money, and our explainer on how supply chains are adapting to new pressures shows how countries are already rethinking who they depend on. Competition between lenders can be good for borrowers.
Third, it reflects a wider shift in the world economy. The fastest growth is no longer in Europe or North America but in Asia, Africa, and Latin America. BRICS is the most visible attempt by those countries to organise themselves and to say that the institutions built after the Second World War should reflect today’s world, not the world of 1945.
What BRICS Does Not Do
It is important not to overstate what the group can do. Its members are very different from one another. China and India are rivals as well as partners, and they have clashed on their shared border. Russia is under Western sanctions over its war in Ukraine, while India and Brazil maintain close trade ties with the United States and Europe. Iran’s membership adds another layer of tension with the West.
Decisions in BRICS are made by consensus, which means any member can block a proposal. That makes bold, binding action rare. The group has talked for years about a shared currency, for example, but there is no agreement on what it would look like, and most experts consider it a distant prospect. Our explainer on the Strait of Hormuz shows how energy politics can divide even countries that share interests — and the same is true inside BRICS.
For ordinary people, BRICS will not change daily life overnight. But it is shaping the background of the world economy: who lends money to whom, which currencies trade is settled in, and who gets a say in writing the rules. That is why a group that began as an economist’s acronym now fills headlines every year — and why it is worth understanding.
