The looming threat of a 10% tariff on U.S. imports of Canadian crude oil hasn’t just angered Canadians — and understandably so, we might add. It’s also put a spotlight on PADD 2 — the Midwest/Great Plains region — whose pipelines transport the vast majority of Canadian exports and whose 25 refineries (combined capacity 4.3 MMb/d) are, in many cases, significant consumers of heavy and light crudes from up north. Put simply, to assess the impacts of the still-possible trade war on U.S. refiners and producers on both sides of the border, you need to understand PADD 2’s crude oil supply/demand balance and the options Midwestern refineries that currently run Canadian crude would have if a tariff were put in place. In today’s RBN blog, we’ll discuss these dynamics.
