It's no secret that President Donald Trump isn't a fan of NAFTA. Throughout his campaign, he promised to rip up trade deals, specifically zeroing in on the North American Free Trade Agreement, the US's trade deficit with Mexico, and the US's loss of manufacturing jobs.
The evidence available, however, favors the position that changing NAFTA would neither reduce the US's trade deficit nor meaningfully increase its manufacturing jobs, according to two charts shared by Bank of America Merrill Lynch's Carlos Capistran and Ethan S. Harris in a recent report to clients.
The first chart, which you can see below, compares the 12-month rolling average for the US trade balance with the world and with Canada and Mexico, its NAFTA partners.
The US's trade deficit with the two NAFTA countries is less than 10% of its total trade deficit, and most of the increase in the total deficit actually came several years after the trade agreement was implemented.
"Most economists agree that trade deficits are the result of saving and investment decisions rather than trade agreements," Capistran and Harris said, adding: "In particular, trade deficits are financed by net capital inflows. Capital flows into the US are strong because of low private savings and large budget deficits in the US and elevated savings in China and other EM economies."
Notably, the economists added, nearly half of the US's trade deficit is with China even without any agreement regulating trade between the two countries.
The second chart shared by Capistran and Harris shows manufacturing jobs' share of total employment since 1980.
As you can see below, the decline in American manufacturing jobs was similar to the declines seen in other advanced economies like the euro area, the UK, and Japan — none of which are in NAFTA.
BAML's chart doesn't go past 1980, but it's worth noting that manufacturing as a share of nonfarm employees in the US has been on the decline since the 1970s.
Taking it a step forward, we at Business Insider previously charted US manufacturing employment since the 1970s with respect to economic and trade shocks.
As you can see below, the big drop-off in manufacturing jobs correlates with China joining the World Trade Organization in 2001. And the steepest decline occurs after 2007-2008 Great Recession.
Of course, trade isn't the only thing that has been a factor in the loss of manufacturing jobs; automation has played a role as well.
And a recent report from Bloomberg suggests that even if NAFTA were scrapped entirely, companies would not stop moving operations to Mexico.
"If they just wiped out NAFTA and went back to normal trade tariffs, I think that's manageable," Ross Baldwin, the CEO of Tacna, a company that helps manufacturers establish operations in Mexico, told Bloomberg. "Life would continue on because the labor rate is so dramatically different."
