Petrobras cut wholesale diesel prices by 4.6% on April 1 to about R3,550 per cubic metre. Trump's reciprocal tariffs then triggered a sell-off, with NYMEX ULSD futures falling more than 10% between April 2 and 8 to a near four-year low.
Cheaper imported diesel and falling futures are pressuring Brazilian diesel prices, which lowers freight and processing costs. Tariff-driven demand concerns also weigh on global energy prices.
