B3 Has Started Publishing a Dollar Ibovespa. It Is an Index, Not Something You Can Trade.
BRAZIL · MARKETS
Key Facts
- —What it is The Ibovespa recalculated in United States dollars, published as an index series.
- —What it is not Not a futures contract, not an exchange-traded fund, and not a tradable instrument.
- —The launch Monday, 14 September 2026, announced the previous Friday.
- —The conversion The WM/Reuters benchmark rate, fixed daily at 4 p.m. London time.
- —Two versions One based on the closing price and one on the settlement price.
- —The catch It is distributed on demand and no public ticker has been published.
A foreign investor in Brazilian equities holds two positions at once. Only one of them has ever been published.
B3 began publishing a dollar Ibovespa on Monday, 14 September 2026. The exchange announced it the previous Friday.
What it is has been reported loosely, and the looseness matters. This is an index series, not an instrument.
The Mechanics
The series takes the existing Ibovespa and recalculates it in United States dollars. The conversion uses the WM/Reuters benchmark rate.
That rate is fixed once a day, at 4 p.m. London time. Using a published benchmark rather than a spot quote makes the series reproducible by anyone.
Two versions are published. One is based on the closing price and one on the settlement price.
Distribution runs through the exchange’s indices-on-demand channel rather than its public index pages. No ticker has appeared in any of the coverage.
Because of that, no code is given here. Readers who need one should request it from the exchange directly.
The Problem It Solves
A foreign investor in Brazilian equities holds two exposures. One is to the companies and one is to the real.
The published Ibovespa has only ever described the first. Working out the combined return meant adjusting the index by the currency move, which every institution did separately and slightly differently.
A dollar Ibovespa does that once, using a single agreed rate, and publishes the answer. It makes Brazilian equity performance directly comparable with dollar-denominated global benchmarks.
Monday itself illustrates the point. The index fell on Monday, 14 September 2026, by about 1% to 1.5% in local terms.
The real weakened between 0.66% and 1% over the same session. Both moves work against a dollar-based holder.
Those are intraday figures rather than settlement prices. The session had not closed when they were taken.
A dollar investor therefore lost materially more than a Brazilian one. That gap is the thing the new series makes visible.

What It Does Not Do
There is no hedging here. Publishing a converted index does not let anyone offset currency risk.
There is also no tradable product attached. You cannot buy the dollar Ibovespa, and no futures contract or fund has been launched against it.
It is a transparency and comparability tool. That is a modest thing, and describing it as anything more would be wrong.
Its practical users are index providers, allocators running global mandates, and anyone writing about Brazilian equities for a foreign audience. It saves each of them the same small calculation.
Two Other Changes at the Exchange
B3 launched a market neutral index the same day. Its theoretical portfolio pairs exposure to the IBRX50 against Ibovespa futures.
Separately, Brazilian depositary receipts may make up as much as 10% of the Ibovespa from the first half of 2027. Those cover foreign-listed shares.
Candidates named in Brazilian coverage include Nubank, XP, PagSeguro, Inter and JBS. Several are Brazilian businesses whose shares are listed abroad.
That change would alter what the Ibovespa measures. A domestic index that admits foreign-listed Brazilian companies is a different benchmark.
Taken together, the three moves point the same way. B3 is making its flagship index easier for foreign money to hold and to understand.
Why Now
The timing is not accidental. A5X, a derivatives venue backed by international market makers, announced a funding round on the same day.
Brazilian equities have also been downgraded by several foreign managers this year on electoral and fiscal risk. JPMorgan cut to neutral in August.
An exchange facing both a domestic competitor and foreign outflows has reason to reduce friction. Publishing a dollar Ibovespa costs almost nothing and removes one small obstacle.
Whether it changes any allocation decision is doubtful. It does remove an excuse, which is usually the point of infrastructure of this kind.
