At the start of 2026, currency markets were mapping a fairly conventional world: a US economy slowing enough for the Federal Reserve to cut rates twice, a cautious European Central Bank and most other central banks content to follow Washington’s lead.
The conflict in Iran ended that script almost overnight.
Energy prices surged, inflation expectations shifted, and central banks began talking about rate rises. The Fed, facing a combination of energy-driven inflation and mounting growth uncertainty, has stayed put.
That divergence has opened the door for a broad range of currencies to gain ground against the US dollar. But each winner has its own story.
The Brazilian real’s near 11% gain year-to-date is the strongest performance of any significant currency against the US dollar in 2026. Two forces are at work simultaneously, and both are pointing in the same direction.
The first is carry. Brazil’s Selic benchmark rate sits at 14.75% — even after the central bank cut it by 25 basis points on 18 March, it remains roughly 11 percentage points above the Federal Reserve’s target.
That gap is near its widest level since the 2022 global tightening cycle, and it creates a powerful mechanical incentive: an investor borrowing in US dollars and parking the proceeds in Brazilian real-denominated assets earns that differential as pure income, every day, as long as the exchange rate holds.
When the real appreciates on top of that — as it has done this year — the returns compound quickly.
This is the carry trade in its most straightforward expression, and Brazil currently offers the highest version of it among any liquid emerging market.
The second force is commodities. Brazil is the world’s largest exporter of soybeans, iron ore, beef and sugar, and a significant crude oil producer.

When global commodity prices rise — as they have in the energy-shock environment of 2026 — Brazil’s terms of trade improve, export revenues rise, and demand for the real strengthens from a completely separate channel.
Carry and commodity windfall are reinforcing each other, which is why the real has outperformed even other high-yielding currencies that lack Brazil’s export mix.
The Reserve Bank of Australia raised its cash rate on 17 March to 4.1%, following a hike in February, a decision that pushed the Australian rate differential against the United States into positive territory for the first time since 2017.
