Oil Slides as Trump 15% Tariffs Hit Demand Outlook

Oil prices dropped on Monday as uncertainty emerged over U.S. trade policies following President Donald Trump's announcement of a 15% tariff on global imports. This decision, following the Supreme Court's invalidation of his prior tariff program, raised concerns about global economic growth and fuel consumption. By 2315 GMT, Brent crude fell to $71.31 per barrel, and U.S. crude futures dropped to $65.98 per barrel according to Reuters.

Goldman Sachs has increased its Q4 2026 Brent Crude price forecast to $60 per barrel and its West Texas Intermediate (WTI) forecast to $56 per barrel. The adjustment follows lower-than-expected OECD inventory levels, which have reduced the market's buffer capacity against supply disruptions.

The Supreme Court's ruling on tariffs introduced uncertainty, affecting global markets and currency valuations. U.S. stock futures fell as uncertainty around Trump's tariffs impacted global markets.

Why the Move Happened

The Trump administration's new tariff policies were seen as a major factor driving oil prices lower. The 15% tariff on global imports was announced after the Supreme Court struck down previous tariff programs. Analysts said the policy shift raised concerns about the global economic outlook and fuel demand.

Goldman Sachs attributed the upward revision of its oil price forecasts to reduced inventory buffers in advanced economies. These buffers typically help absorb supply shocks, but with OECD stock levels lower than expected, the market has less cushion.

The new tariffs remain in effect for up to 150 days, and market participants are closely monitoring their potential long-term implications on global trade flows and energy demand.

How Markets Reacted

The euro gained against the dollar as uncertainty about how the new tariffs will be imposed remained. U.S. Treasurys yields edged lower, and there were concerns about potential government funding issues.

Oil traders are also responding to diplomatic developments between the U.S. and Iran. While tensions escalated last week, prices have softened following planned talks that could lead to a diplomatic solution. The geopolitical risk premium remains elevated, supporting speculative interest in oil.

Speculative positioning data shows that net long positions in ICE Brent have been reduced. However, geopolitical uncertainty continues to support some speculative activity in the oil market.

What Analysts Are Watching

Analysts are watching how the new U.S. tariff program will affect global economic growth and energy demand. The Trump administration's shift in trade policy could impact manufacturing and transport sectors, which are significant oil consumers according to Reuters.

The limited spare capacity in the global oil market adds to the vulnerability of the energy sector. A potential U.S.-Iran conflict could disrupt 3 million barrels of daily production, which could have a significant impact on global oil markets.

Saudi Aramco's CEO has noted that global oil stocks are low, and spare capacity is at a critical level. These developments raise questions about the market's ability to absorb potential supply disruptions from a potential U.S.-Iran conflict.
