Key Facts
Copom cut the Selic to 13.75%, a quarter-point reduction that was priced at roughly 95% odds in B3 options before the decision.
The real remains pinned near the strong end of its 52-week band, with support around 5.10 and resistance near 5.15 per dollar on traders’ radar.
Petrobras is set to raise diesel reference prices, but the increase will be fully neutralised by a government subsidy, leaving pump economics unchanged.
Today’s B3 calendar is light on local data, so the open will be driven by post-Copom positioning and how Wall Street digests the Fed’s overnight tone.
The Ibovespa still sits below its 52-week high as investors weigh whether cheaper money can offset fiscal anxiety and a strong US dollar.
Today’s Focus
The big event has already happened. Brazil’s central bank cut the Selic, the benchmark interest rate, by a quarter of a point to 13.75% on the evening of Wednesday 16 September, leaving Thursday 17 September to trade the aftermath — the fifth consecutive reduction in a cycle that began at 15%.
The move was unanimous and broadly expected: market-implied odds on B3’s Copom options had settled near 95% for exactly this outcome. That means today’s trading is less about shock and more about what the central bank signals for December, when opinions are split between a pause and one final cut this year.
In the currency market, the real is trading close to the stronger side of its recent range. The level to watch is 5.10 per dollar on the downside and 5.15 on the upside — a break either way tells you whether global dollar strength or local rate relief is winning.
On the corporate side, Petrobras is front and centre. The state-controlled oil giant will raise diesel reference prices, but the increase is fully offset by a government subsidy, so the net effect on distributors is zero. That is a political masterstroke, but investors will be watching whether it mollifies truckers without provoking the fiscal hawks.
What matters today. Whether the Copom’s message and today’s US data releases keep the real trading near 5.15 or push it towards the 5.10 support level.

Ibovespa — Wednesday, 16 September 2026 close.
01 The setup in one read
Brazil’s central bank delivered the expected cut last night, lowering the Selic to 13.75% in a unanimous decision. The B3 options market had already priced this at around 95% probability, so the question for today is not whether the cut happened, but what comes next.
The real is the anchor to watch. It is holding in the stronger half of its 52-week range against the dollar, with support around 5.10 and resistance near 5.15. A push through either side will signal whether traders believe in more local easing or are bowing to global dollar strength.
On the corporate radar, Petrobras is making a clever political move on diesel prices: it is raising the reference price but offsetting the entire increase with a subsidy. The net price for distributors stays unchanged, which could keep truckers quiet without adding to the company’s costs.
Today’s Brazilian data calendar is extremely light. The macro focus shifts to US industrial production and leading indicators later in the day, while Brazilian traders digest the Copom statement and reposition for the final quarter.
The evidence points to a market that has already moved past the decision itself and is now trading the path forward. With the Copom decision unanimous and well-telegraphed, the marginal driver for B3 today is the tone of the central bank’s statement and how the US dollar index behaves after yesterday’s Fed-related moves.
The variable to watch is the USD/BRL’s ability to hold above 5.10. If the real strengthens through that level, it signals local conviction in further easing. If it slips back towards 5.15, global dollar pressure is overwhelming the domestic story.

The board shows the Ibovespa closed lower on Wednesday as markets awaited the Fed and Copom decisions. Today’s indicated open is cautiously higher as traders absorb the rate cut that was already priced in.
The USD/BRL is the key barometer. If the real holds below 5.15 and tests 5.10, it confirms local rate relief is outweighing global dollar strength. A move back above 5.15 would suggest the Fed’s message from yesterday is still pressuring emerging-market currencies.

Shows whether foreign funds are long or short the real
There are no Brazilian economic data releases today, which puts the focus squarely on corporate stories and the post-Copom read. The Petrobras diesel news is the headline corporate event, even though the subsidy means the net price to distributors is unchanged.
US industrial production and the leading index will shape the global risk mood. If those numbers come in soft, the dollar could weaken and help the real test 5.10. Strong data would reinforce the dollar and keep USD/BRL near 5.15.
Later tonight, the CFTC data on speculative BRL positions will show how committed foreign traders remain to the long-real trade. This is a crucial input for whether the 5.10 support holds in the coming sessions.
04 Copom and the macro backdrop
The Selic now stands at 13.75%, the lowest since March 2025. The central bank has delivered five straight quarter-point cuts from a peak of 15%, and the messaging has been consistently data-dependent — no commitment to pause or extend the cycle.
Economists are genuinely split on what happens in December. The Valor survey median sees the Selic at 13.50% by year-end, meaning one more cut. But roughly half of respondents expect a pause after this week’s move, while the other half see additional easing.
The real interest rate is still among the highest in the world — a fact local media highlighted this morning. Even after the cut, Brazil’s real rate remains above 8%, which is a powerful magnet for carry-trade flows into the real.
The B3 Copom options market will now shift to pricing the December meeting. Early signals suggest a coin-flip between a hold at 13.75% and a final cut to 13.50%, with the December meeting’s odds likely to swing on inflation prints between now and then.
05 Corporate stories to watch today
Petrobras is the day’s main corporate story. The company is raising diesel reference prices, but the government’s subsidy mechanism neutralises the entire increase, leaving the net price to distributors unchanged. This keeps the political peace with truckers while avoiding a direct hit to Petrobras’s margins.
The market will be watching whether investors read this as positive for Petrobras — no margin squeeze, no strike risk — or negative, because the subsidy itself is a fiscal cost the market has been trying to ignore. PETR4 and PETR3 saw heavy turnover yesterday, and that focus continues today.
Vale remains in play as the iron ore bellwether. With China’s property sector still struggling, any move in ore futures during Asian trading will set the tone for VALE3, which was the most-traded stock on B3 yesterday.
Banks like Itaú and Banco do Brasil may find some relief from the rate cut’s confirmation that the easing cycle is intact. Lower rates compress net interest margins, but they also reduce credit risk and support asset prices — the trade-off traders will be weighing this morning.
06 The levels to watch at the open
For the Ibovespa, the 185,000 zone is the first line of defence. The index closed just above that level yesterday, and a hold above it would confirm that the rate cut is providing a floor. A break below would open the door to the 183,500 area.
The USD/BRL’s 5.10 support is the crux. The currency has been trading in the 5.12–5.16 range into the Copom decision, and today’s reaction will define whether the real can make a run at its strongest levels since early 2025.
On the upside for the real, a decisive break below 5.10 would signal that local conviction in the easing cycle is translating into actual currency strength. That would be a powerful signal for Brazilian equities, especially domestic-facing names.
If the dollar takes control and USD/BRL pushes back above 5.15, it would suggest global factors are overriding the Copom’s message. In that scenario, the Ibovespa’s opening gains would likely fade, and defensive positioning would return to the fore.

Frequently Asked Questions
What did Copom decide?
Brazil’s central bank cut the Selic rate to 13.75% from 14.00%, a unanimous quarter-point reduction that was broadly expected by economists and priced in by B3 options markets.
How will the rate cut affect the real?
The real is trading near the stronger end of its recent range. Support at 5.10 per dollar is the key level — a break below would confirm local rate relief is outweighing global dollar strength.
Why is Petrobras in the news today?
The company is raising diesel reference prices, but the government’s subsidy neutralises the entire increase, leaving the net price to distributors unchanged. It is a politically crafted move with no direct cost to Petrobras.
What Brazilian data comes out today?
The local calendar is empty. The macro focus turns to US industrial production and the leading index, plus the CFTC’s positioning data on the real later tonight.
