Goldman Pours Cold Water On Trump's Fiscal Stimulus Plan

Goldman Sachs' Chief US Political Economist Alec Phillips writes that tax reform faces a risk of failure, but tax cuts remain likely... in 2018 and investors need to stay realistic about the impact of fiscal stimulus.

President Trump’s campaign proposals initially raised expectations of several forms of fiscal stimulus, driving investor optimism on both infrastructure spending and various elements of tax reform. However, we expect only tax cuts to have a meaningful effect on growth over the next couple of years. Three risks are behind this view: tax reform failure, fiscal constraints, and delayed enactment.

Debates, delays, distractions

First, tax reform faces a real risk of failure. If Republicans pursue revenue-neutral tax reform, they are likely to encounter the same challenges they encountered in passing their health legislation. Inclusion of controversial proposals like the border-adjusted tax (BAT) or even the repeal of corporate interest expense deductibility, for example, could sink the effort. Views on these issues do not follow traditional party lines, which could easily lead to some Republican opposition (we have already seen significant opposition to the BAT, for example). With few if any Democratic lawmakers likely to vote for the tax bill, Republicans would need nearly unanimous support from their own party. Thus, while revenue-neutral tax reform might be preferable from a policy perspective, imposing this restriction would lower the odds of enactment by next year.

In light of the challenges tax reform faces, we believe that President Trump, who did not emphasize revenue-neutrality during the campaign, is likely to eventually endorse more limited reforms that result in a net tax cut. However, the size of such a cut would be limited by fiscal constraints; centrist Republican lawmakers seem especially likely to balk at large tax cuts that would eventually require deep spending cuts to maintain fiscal sustainability. Dynamic scoring and other budget accounting strategies might provide several hundred billion dollars’ worth of room for a tax cut in 10-year budget projections, but alone would allow for only a very modest cut. Our current expectation is a tax cut of $1.75tn over ten years, taking effect in 2018.
