| Hey, readers! I can't believe it's already June and that we're nearly halfway through the year. To everyone who thought we'd see a summer news slowdown, remember that Donald Trump is in power. This week the American president again threw the economy a curve with a further escalating of the global trade war. In a tweet Trump said the US would impose tariffs of 5% on Mexican imports starting June 10. If you're new to the Wall Street Insider newsletter, you can sign up here. Trump said these tariffs would be in place "until such time as illegal migrants coming through Mexico, and into our Country, STOP." Trump said he'd boost the initial 5% tariff all the way up to 25% if the border isn't controlled. Our investing editor Joe Ciolli breaks down the effects the tariffs would have. In the US, JPMorgan estimates that new tariffs will reduce third-quarter gross domestic product by a quarter point, from 1.75% to 1.5%. The firm warns that a much bigger downward revision may be necessary if a corporate spending slowdown affects hiring, which could hurt consumer spending. There's been ongoing speculation that Trump's recent tariffs are serving as an indirect tax on the average person. After all, when a tariff is imposed, the manufacturing company doesn't necessarily have to make up the difference on their end. They can always pass that additional cost along to the purchaser. And then there's the matter of markets. With US stocks getting pummeled this past week, it's clear investors are allergic to Trump's trade uncertainty. Meanwhile, in the bond market the scared rush into Treasurys, considered to be among the safest assets, has pushed yields into dangerous territory. Near-term yields are higher than their long-term counterparts, something that's historically signaled an imminent recession as it implies nervousness. This is commonly referred to as a yield-curve inversion, and the current situation is more stretched than at any point since 2007. Joe also points out that any Mexico tariffs would be in addition to the China tariffs already enacted. The trade war has already had a meaningful effect. Companies have started warning investors about the downside they might face if the trade war doesn't end soon. That includes Stanley Black & Decker CEO James Loree, who said recently that his firm may go as far as to move production back to the US from China in response — a costly, complex endeavor. Don't expect Trump to let up anytime soon. Between China and Mexico, tariffs appear to be his favorite policy weapon.

Candidates go through a phone screener, followed by five in-person interviews, and sometimes a behavioral assessment, all to analyze a wide variety of skills and traits. Peng Zhao, the firm's CEO, signs off on the hiring of all employees, including interns. It's a highly selective process as fewer than 2% of applicants are hired — a lower acceptance rate than at Harvard.
