On March 27, according to Jin Ten Data, crude oil prices fell in morning trading as traders weighed the impact of U.S. President Donald Trump's 25% tariff on all imported cars and trucks on global demand. Crude oil futures settled 1 per cent higher in the previous session on concerns about tighter supply as a result of US export pressure on Iran and Venezuela and falling US inventories. Traders are now waiting for the White House to announce reciprocal tariffs on US trading partners on Wednesday. "Until the size, scope and implementation details of the tariffs are clear, risk appetite is likely to remain subdued," said analysts at ANZ Research.
