The market response to Donald Trump’s decisive re-election victory last week, and the Republican party’s likely clean sweep of Congress, was equally unequivocal. The S&P 500 finished the week up 4.8%, probably driven in large part by hopes for another round of corporate tax cuts under President Trump and a Republican Congress. Ten-year US government bonds (Treasuries), the benchmark for US and global borrowing costs, moved in the opposite direction, pushing yields higher. However, we don’t think the longer-term outlook for stocks or bonds is so clear cut.
Looking at Trump’s plans in the round, widespread tax cuts, higher tariffs and restricted immigration could add up to higher inflation and interest rates – anathema for bond investors. But after a challenging week, the start of the new one has brought some much-welcomed calm to government bond markets. This may be an acknowledgement that there are still a few months before Trump even sets foot in the Oval Office (inauguration day is 20 January), but we’ll have to wait and see if this is just a temporary reprieve.
While corporate tax cuts under Trump could strengthen economic growth in the short term, inflation is likely to be higher, as we noted in our US election update on the day of Trump’s victory. US government bond yields could also go up in response to a widening deficit. Growth would likely weaken in the longer term, restrained by higher rates and potential government belt tightening.
For context, one of the flagship pieces of legislation during Trump’s previous term as president was the 2017 Tax Cuts and Jobs Act (TCJA), which cut the headline rate of corporate tax from 35% to 21%. The TCJA is due to expire at the end of 2025, and Trump has proposed not only making these cuts permanent, but going a step further with a reduction to just 15%.
We estimate that this would increase annual post-tax earnings by 8% for a company paying the headline rate of corporate tax. Given the long-term growth rate of earnings is 7% in the US, that’s more than a full year’s worth of typical growth added on top.
This could be strongly positive for US stocks, and such cuts could initially provide a stimulus to economic growth. The long-term impact would be more uncertain; the resultant widening in the deficit would be negative for US government bonds, raising borrowing costs for consumers and businesses.
US equity investors have generally cheered Trump’s return, but the mood was different in the rest of the world. Not only would non-US stocks not have any direct benefit from lower US corporate taxes, but they face the spectre of ‘universal tariffs’ under Trump 2.0.
Increased tariffs could be a problem for US equities too. If anything close to Trump’s full ‘universal tariff’ is implemented, inflation could be pushed temporarily higher (analysis in our pre-election report suggested by one percentage point or more), while economic growth would be temporarily weaker. By how much depends on how much other countries retaliate, how tariff revenue is used, and how the Federal Reserve reacts.
There is considerable doubt about both Trump’s willingness and his ability to implement his plan. And one question we’ll be pondering is whether Trump’s mooted tariff increases are more of a negotiating tactic than a definite plan
