Oil prices surge, and Lula bets on fuel tax cuts—while Brussels and Washington redraw the rules

On September 9, 2026, Brazil’s President Luiz Inácio Lula da Silva announced additional cuts to fuel taxes to shield consumers from surging oil prices ahead of the presidential election. Reporting from Bloomberg and O Globo indicates the government is expanding a gasoline-focused measure as a temporary fuel subsidy (via MP 1358/2026) expires the same day. The policy shift replaces the expiring subsidy with a federal tax desoneração on gasoline starting Thursday, while economic teams finalize the exact cost of the fuel subsidy for gasoline and diesel. Separately, the U.S. Department of Energy raised its forecast for the average Brent price path, projecting Brent to average $73.74 per barrel in 2027 after a near-term rise, with the rationale tied to rising global production and recovering inventories. Geopolitically, the cluster shows how energy price volatility is being converted into domestic political leverage across major economies. Lula’s fuel-tax strategy is designed to blunt inflation pressure and protect voter sentiment in the final stretch of the campaign, turning commodity dynamics into an electoral instrument. In Europe, António Costa, President of the European Council, warned that new EU-wide taxes could reduce member-state transfers to Brussels, signaling a fiscal bargaining posture ahead of the informal deadline to agree the EU budget for 2028–2034. While the EU tax discussion is not directly about oil, it matters because it shapes how governments can fund subsidies or tax relief when energy shocks hit, and it influences market expectations for fiscal discipline versus consumer support. Market and economic implications are immediate for oil-linked inflation expectations and for Brazil’s domestic fuel pricing channel. A shift from subsidy spending to tax desoneração can change the timing of fiscal costs and the pass-through to retail prices, affecting inflation gauges such as Brazil’s IPCA; one O Globo report suggests fuel benefit expansion could reduce IPCA by about 0.15 percentage points in the run-up to the election period. For global benchmarks, the DOE’s Brent forecast revision supports a more structured view of the forward curve: near-term pressure may persist, but 2027 averages are expected to soften as inventories recover, which can influence hedging strategies in energy derivatives and the pricing of shipping and refining margins. In Europe, potential new EU taxes that alter net contributions can indirectly affect sovereign spreads and the cost of capital for countries that may need fiscal room to manage energy-related relief. What to watch next is the fiscal arithmetic and the political durability of Brazil’s fuel measures as the election approaches and as oil price volatility persists. Track the final published calculation of the subsidy/tax relief cost for gasoline and diesel, and monitor retail price adjustments and inflation prints for evidence of the claimed IPCA impact. In Europe, watch negotiations around the EU 2028–2034 budget and any concrete design of EU-wide taxes that could change transfer flows to Brussels, since these decisions affect governments’ ability to respond to energy shocks. For markets, the key trigger is whether Brent’s realized path deviates from the DOE’s assumptions on production and inventory recovery; a faster-than-expected inventory drawdown would raise the probability of renewed consumer support measures and volatility in energy-linked FX and rates.

Geopolitical Implications

• 01

  Energy price volatility is being operationalized as electoral stabilization policy in Brazil, increasing the likelihood of politically motivated fiscal measures during commodity shocks.

• 02

  U.S. energy outlook revisions influence global hedging and risk pricing, indirectly shaping the cost of capital and inflation expectations for importers like Brazil.

• 03

  EU budget and tax design debates affect member-state fiscal space, which can determine how quickly governments can deploy or withdraw energy relief without triggering market stress.

Key Signals

• —Published exact budget cost for gasoline and diesel relief and any follow-on adjustments if oil prices keep rising.
• —Brazil’s retail fuel price pass-through and near-term IPCA readings around the election window.
• —Any concrete EU proposal details on EU-wide taxes and their impact on net transfers to Brussels.
• —Brent inventory and production data that confirm or contradict the DOE’s 2027 recovery assumptions.
