The Trump administration, as is its wont, has been chock full of absurdities these last 48 hours. There was Donald Trump inviting Philippines President Rodrigo Duterte, who is allegedly responsible for thousands of extrajudicial killings, to the White House (and Duterte suggesting he might be too “tied up” to attend); there was Trump suggesting that the Civil War could have been avoided if Andrew Jackson, a consummate negotiator like himself, had been in charge (and musing aloud if the Civil War was really necessary); there was the president of the United States saying he’d be “honored” to meet with North Korean dictator Kim Jong-un (and Press Secretary Sean Spicer defending Trump’s praise as “diplomacy”).

Wall Street is slowing learning to ignore the words that come out of Trump’s mouth. Yet the president is still keeping things interesting by doing his best to throw traders for a loop. On Monday, Treasury Secretary Steven Mnuchin told a room full of investors at the Milken Global Conference that “You should all thank me for your bank stocks doing better,” a reference to the soaring stocks of financial institutions, up with the broader market since the November election. Part of the reason for the so-called Trump Bump is Wall Street and investors' hope that the Trump administration will pass a massive tax-reform package and make good on his promise to gut financial regulations. Then, within the hour, as if on cue, the president said in an interview with Bloomberg that he’s “looking at” breaking up the big banks by bringing back the Glass-Steagall Act, which separated consumer and investment banking and was abolished in 1999. Naturally, that comment led to headlines like this:

While breaking up the banks wouldn’t necessarily be a bad thing—Democrats have long pushed for the move, arguing that repealing Glass-Steagall was “a major factor in the 2008 crash” and the G.O.P. actually put it on its party platform in July—one gets the sense that Donald Trump has no idea what he wants or plans to do when it comes to policy, and is “looking into” whatever he’s asked about at any given moment. As Ritholtz Wealth Management C.E.O. Josh Brown said Monday on CNBC, “Stop—please don't make changes to your portfolio based on things that get blurted out.”

People like Senator Elizabeth Warren, who really want to bring back Glass-Steagall probably shouldn’t be getting too excited about today’s comment because, as a reminder, Trump is also “looking into” blowing up Dodd-Frank, the financial regulations put in place following the 2008 financial crisis. Will that happen? Keep in mind that Trump also said he would “look into” Bill and Hillary Clinton; that he would “look into” suing Ted Cruz; that he would “look into” expelling the nation’s Muslims. None of those things happened, so why should this?
