Contrary to what would normally be suggested by the solid US economy, low unemployment, falling inflation and strong share market, Donald Trump has been re-elected President of the US. Clearly some combination of the cost-of-living surge, the immigration blow out and too much ‘wokeness’ along with various other things weighed against Kamala Harris. Counting is continuing but Trump looks to have secured at least 270 of the 538 electoral college votes and won the popular vote. The Republicans are also on track to regain control of the Senate &, although its close, look like retaining the House, resulting in a Red Sweep. Trump’s victory portends a ramping up of trade wars and increased economic policy uncertainty with the high risk of weakening of US institutions, democracy & global alliances.
Trade: Trump is threatening a big ramp up in protectionism with a 10-20% tariff on all goods imports and a 50-60% tariff on goods from China. This would take the average US tariff rate on imports from around 2.5% to at least around 17%, a level last seen in the 1930s, and it was a disaster then!

Immigration: Trump will aggressively curtail immigration and is threatening mass deportation of between 15-20 million undocumented people.
Fed independence: Trump would seek to replace Jerome Powell, and his supporters are looking at ways to roll back the Fed’s independence.
Climate policy: Trump will likely reverse the US’ net zero commitments and support fossil fuels (“drill baby drill”). Subsidies for green manufacturing are likely to be replaced with wider support for domestic manufacturing (such as a 15% corporate tax rate on domestic profits and tariffs).
Regulation: Trump is likely to slash energy and financial regulation.
Budget deficit: The deficit – already huge at 6.5% of GDP - would likely get bigger under Trump by around 2-3 percentage points of GDP.
Second, expect another ramp up in trade wars and further deglobalisation – in practice Trump is likely to target countries with a trade surplus with the US (notably China, Europe and Japan) and rewrite of the trade deal with Canada and Mexico. The tariffs may not get as high as he has been talking about and it may be part of a “maximum pressure” campaign to bring production, including by Chinese manufacturers, back to the US. The latter may be the case, but we could go through a lot of disruption as Trump initially ramps up the pressure resulting in a much bigger impact on share markets than seen in 2018 (where Trump’s trade wars contributed to an almost 20% fall in shares). This time around the proposed tariffs are much bigger (first chart) & he only backed away in 2019 out of a desire to get re-elected which is not an issue this time around. In any case Trump has long been a protectionist suggesting his tariff threats may be an end in themselves. And tariff hikes this time around will likely be made worse as impacted countries hike tariffs on US imports in retaliation (with reports Europe is planning to hit back quickly). The net impact will be a further reversal in global trade and globalisation.
Third, expect increased policy uncertainty – this was a key feature of his first term and flows from Trump’s own erratic approach to policy making. Back to watching the US President’s social media posts!
Fourth, the US is likely to become more polarised, including around how to deal with economic challenges – this was a feature of Trump’s first term and arguably continued under Biden (albeit more mildly). Trump is likely to treat his win as a vindication of his policies and may double down. This could make it harder for the US to reach compromises to solve economic challenges and lead to increased social unrest threatening US democracy.
Fifth, increased geopolitical uncertainty - Trump’s re-election may further weaken global institutions and cooperation, resulting in a further deterioration in multilateral cooperation and increased geopolitical uncertainty. For example, his policy to negotiate an end to the war in Ukraine (which could be a short term positive globally) would almost certainly involve Ukraine ceding territory to Russia which could embolden Russia particularly if Trump weakens or withdraws from NATO.
Finally, the sequencing of policies may have a big impact on investment markets – if he focusses initially on tax cuts and deregulation then US (and hence global) shares could rally further in response as we saw in 2017. But if he goes early and hard on tariffs then any near-term rally in shares could be brief. His inability to have a third term suggests a high risk of the latter.
His policies on tax cuts and deregulation could help boost the supply side of the US economy via increased investment in the US resulting in a boost to productivity. However, on balance Trump’s policies – with higher tariffs resulting in higher import prices and less competition (which is bad for productivity), deportation and lower immigration resulting in lower labour force growth (which will lower potential economic growth) and potential moves to weaken the Fed’s credibility – risk adding to inflation and being negative for US growth. His trade policies with a likely global trade war would be negative for global growth.
There is also a risk that an even higher US budget deficit when US public debt is already very high (at 125% of GDP), will cause a market backlash resulting in much higher bond yields.
As noted in the previous section, much will depend on sequencing. If he runs with tax cuts and deregulation first (as in 2017) it could boost shares and the economy in say 2025, but if he runs first with sharp tariff hikes and immigration cuts it could be taken more negatively early on.
Some of these moves had already started prior to the election – with bond yields, the $US and Bitcoin all up over the last month - as a Trump victory started to be anticipated and they have gathered pace in the immediate aftermath (with Bitcoin at a record high). It’s likely that they have further to go in the short term but note that this win for Trump is very different to 2016 where his win surprised markets resulting in big market moves. At the time of Trump’s victory in 2016 shares were relatively undervalued and soared 38% into January 2018 as the focus in his first year was on business-friendly tax cuts and deregulation but they fell in 2018 as the focus shifted to trade wars. This time around shares are already expensive so the upside may be more limited. That said shares may still see further post-election gains on relief that it’s out of the way and hope that he focusses more on tax cuts and deregulation, but this could be reversed if he starts focussing on tariffs and as higher bond yields are bad news for shares.
Historically US shares have done best under Democrat presidents with an average return of 14.4% pa since 1927 compared to an average return under Republican presidents of 10% pa. Fortunately, the Republican sweep scenario has been the second-best outcome for shares since 1970. If the Republican’s lose control of the House though, Trump will struggle to cut taxes, and this could see less upwards pressure on bond yields but be bad for shares as Trump could still do the tariff hikes.

There is also the risk that if Trump’s policies boost US inflation there could be a global flow on, including to Australia, resulting in higher than otherwise RBA interest rates. This is a risk, but I suspect it would be offset by the growth dampening impact of an intensified global trade war.
From a policy point of view, if Trump cuts the US corporate tax rate to 15% on domestic profits it could renew pressure on Australia to cut its corporate tax rate. Trump’s reversal of US climate policies will again add to confusion and may increase pressure for Australia to slow its net zero commitment.
