Reports have emerged that the Trump administration is taking concrete steps to pull the United States out of the North American Free Trade Agreement, also known as NAFTA.

According to Politico, two White House officials stated that a draft order to withdraw from NAFTA has already been submitted for the last stages of review, and could be released by the end of this week, or early next week.

The order was written by Trump’s head of the National Trade Council, Peter Navarro, in corroboration with the White House chief strategist Steve Bannon. It is still unclear what the order states, but the effect on trade can be predicted by an examination of the top 20 exports arriving from Mexico to the US.

In January Capital Economics’ chief emerging markets economist Neil Shearing published a chart in a memo to clients graphing the top 20 exports from Mexico according to their 2015 US dollar value.

About 25 percent of Mexico’s total exports to the US, by far the largest slice, came from the auto sector, valued at about $80 billion. The next three items are electrical components, food, and computers, together valued at about $55 billion.

“The upshot, then, is that targeted measures imposed on the vehicle, electronics, and food and beverage sectors would hit Mexico’s economy especially hard,” wrote Shearing. “Similarly, in the event of a blanket tariff across all sectors, producers in these areas would be among the hardest hit.”

In wake of the reports that Trump is on the verge of pulling out of NAFTA the peso is crashing, down over 2.2 percent at 19.2704 as of 12:53pm Wednesday afternoon.
