Op-Ed: Will politics trump economics?
Carlos Barria | Reuters · CNBC

President Donald Trump has inherited an economy that is in much better shape than his predecessor did eight years ago. Nonetheless the new president has ambitious plans for his first 100 days in office. Just how much can he achieve and what will be the likely impact on capital markets?

The "first 100 days" is a term frequently used in U.S. politics to measure the initial accomplishments of a new president. It dates back to 1933 when former president Franklin D. Roosevelt used the term to describe the first 100 days of the 73rd U.S. Congress. Roosevelt's objectives were not very different from Trump's - both men came to power with a pledge to make the U.S. great again.

Roosevelt's attempts to address the Great Depression resulted in 15 new bills being passed during his 100 days. These collectively formed the foundation of his "New Deal" and included the abandonment of the Gold Standard and the implementation of the Glass-Steagall Act, separating the banking and securities industries.

"Donald Trump's Contract with the American Voter" is a blueprint the President drew up in October listing his plans for his first 100 days. Among the measures mentioned are repealing and replacing the Affordable Care Act, withdrawing from the Trans-Pacific Partnership and cancelling many of Obama's executive orders. However, as Ronald Reagan was quick to acknowledge when taking office, it is not as easy as it was in Roosevelt's day to pass swathes of new legislation. Trump is going to have to pick his battles and use his political capital wisely.

Obamacare alternative?

Repealing the Affordable Care Act appears a high, if not top, priority, and one with broad support in the Republican-controlled Congress. However, repealing is the easy bit, replacing is anything but. The non-partisan Congressional Budget Office estimates that 18 million people could lose insurance when the act is shelved. There is currently no real alternative that enjoys a clear consensus of support, not even within the Republican Party. Consequently, replacing Obamacare will take effort and compromise, potentially deflecting Washington's attention from the other ambitions of the 45th President.

Another feature of the Trump agenda is a $1 trillion infrastructure commitment over the next decade. However, those expecting an immediate growth boost from infrastructure spending are likely to be disappointed. There is no existing mechanism to implement such a plan on that scale. Options include block grants to states or the establishment of an infrastructure bank, both of which require legislation.
