Fitch Ratings has released an analysis of the Trump Administration’s tax reform proposal, which estimates that while growth would receive a short-term sugar hit, the US’ “structural” Budget deficit would also expand, lowering long-term growth, in addition to increasing inflationary pressures and causing monetary tightening:
Such reform would deliver a modest and temporary spur to growth, already reflected in growth forecasts of 2.5% for 2018. However, it will lead to wider fiscal deficits and add significantly to US government debt. As such, Fitch has revised up its medium-term debt forecast.
US federal debt was 77% of GDP for this fiscal year. Fitch believes the tax package will be revenue negative, even under generous assumptions about its growth impact. Under a realistic scenario of tax cuts and macro conditions, the federal deficit will reach 4% of GDP by next year, and the US debt/GDP ratio would rise to 120% of GDP by 2027.
The Republican tax plan delivers a tax cut on corporations, seeking to lower the corporate tax rate to 20% from 35%, and removing many exemptions, while eliminating some tax breaks affecting corporate and personal filers. It would leave the overall personal tax burden somewhat lower, although the effects would differ depending on circumstances.
Tax cuts may lead to a short-lived boost to output, but Fitch believes that they will not pay for themselves or lead to a permanently higher growth rate. The cost of capital is already low and corporate profits are elevated. In addition, the effective tax rate paid by large corporations is well below the existing statutory rate. From a macroeconomic perspective, adding to demand at this point in the economic cycle could add to inflationary pressures and lead to additional monetary policy tightening.
Fitch expects US economic growth to peak at 2.5% in 2018 before falling back to 2.2% in 2019. The US will enter the next downturn with a general government “structural deficit” (subtracting the impact of the economic cycle) larger than any other ‘AAA’ sovereign, leaving the US more exposed to a downturn than other similarly rated sovereigns.
The US is the most indebted ‘AAA’ country and it is running the loosest fiscal stance. Long-term debt dynamics are also more negative than those of peers, with health and social security spending commitments set to rise over the next decade. In Fitch’s view, these weaknesses are outweighed by financing flexibility and the US dollar’s reserve currency status, underpinning its ‘AAA’/Stable rating. The main short-term risk to the rating would be a failure to raise the debt ceiling by 1Q18, when the Treasury’s scope for extraordinary measures is expected to be exhausted. The debt ceiling is currently suspended until early December.
