There is much we don't know about how the Trump presidency will play out. Will the Wall get built? Who will pay for it? Will it have at least some fencing? Will repeal and replace happen at exactly the same time? Will Trump throw a ceremonial switch? Will there be a Trump National Golf Course in Sochi? It's anyone's guess. But of one thing we can be fairly certain. President Trump is very likely to preside over the largest expansion of Federal budget deficits in our history. Trump has built his companies with debt and I'm sure he thinks he can do the same with the country. His annual budget deficits are likely going to be huge. This development will make a greater impact on the investment landscape than most on Wall Street can imagine.
In the past half-century, Republican presidents have been the going away winners at the deficit derby, a fact that should make any true conservative blush. The sad truth is that annual deficits exploded under Ronald Reagan and George W. Bush, and generally contracted under Bill Clinton and Barack Obama. Some of the explanation is just luck of the draw, some walked into office in the midst of recessions they didn't create. But the better part of the explanation is baked into the political dynamics.
Democrats want to raise spending and taxes. Republicans want to cut spending and taxes. But whereas Democrats have generally succeeded on both of their missions, Republicans have just succeeded in one. (Actual spending cuts require politically difficult choices that are much harder to vote for than perennially popular tax cuts). This puts a giant thumb on the Republicans' budgetary scale.
Like prior Republicans, Trump has promised to cut taxes, on both corporations and individual taxpayers...even the wealthy. But unlike prior Republicans, he has not paid a word of lip service to spending cuts. He has promised to spend now, and spend big. Trump just doesn't do the austerity thing. It's for losers.
In addition to fronting the cost of building the 2,000 mile Wall (accounts receivable has a reliable address in Mexico), Trump plans big increases in military spending, both on active military and on our veterans. His reboot of Obamacare has yet to be presented, but as he has promised that no one will lose coverage, not even those with pre-existing conditions, we can be sure that Trumpcare won't be cheap. But his big project will likely be his promised $1 trillion plus infrastructure spending plan. Most importantly, he diverges from most Republicans by promising no structural changes in Social Security and Medicare, the entitlement leviathans that are the sources of the vast majority of Federal red ink.
To aid him in these budget-busting efforts, Trump will have the benefit of a compliant Congress in which his own party controls both Houses. Most Republican senators and representatives now seem eager to jump aboard the Trump train and will likely pass anything he sends to the Hill. Those who resist should prepare for the kind of political hardball that we have rarely seen in this country (I'm talking to you Lindsay Graham). If Republicans couldn't hold the line on Obama, how will they do so with Trump and, politically, why would they even want to? Grandstanding against Obama's big deficits, even to the point of forcing a government shutdown, did not play well politically. Standing up against Trump will involve considerably more risk with Republican primary voters.
Even if none of Trump's taxing and spending plans come to fruition, the United States would still be on the threshold of a sobering era of debt expansion. The age of trillion dollar plus annual deficits began in 2009 when the financial crisis tripled a very large $458 billion deficit in 2008 into a record smashing $1.4 trillion in 2009. Three more trillion-dollar deficits followed. But since 2009, excluding a small increase from 2010 to 2011, the deficits have declined steadily. By 2015, they had decreased to $438 billion, slightly below where they were before the crisis began. (Of course these smaller deficits exclude hundreds of billions of additional debt that is borrowed off budget.) These developments have caused many to conclude that budgetary issues are no longer at the top of the agenda.
