The Republican administration in the US has kept investors guessing with a constantly shifting dialogue on tariff implementation. But has the plan finally been revealed?
At a glance
- The US president has suggested that discussions of tariffs is a strategy to encourage goods production to move back to the US
- Looking only at export data underplays the impact that US companies have on the world. Sales generated by US-owned companies in overseas markets are highly significant.
- From a tariff perspective, the US is a relatively closed economy. From a political perspective it is not so clearcut.
- Using tariffs may well stoke US inflation but the impact will probably be limited by several factors, according to the Nutmeg investment team
The data suggests that tariff implementation is not the main game for the Republican administration. Sure, the threat – and indeed reality – of tariff increases is intended to extract better deals from trading partners. But the main aim is likely to be to reshore as much production to the US as possible.
Has the president shown his hand?
Amongst a lot of geopolitical noise, on 11 March the president implied that tariffs were just a stepping stone.
“The biggest win is not the tariff – that big win is a lot of money – but the biggest win is if they move into the country and produce jobs”.
The structure of the US economy certainly backs up that potential tariff 'wins' may be limited. The US economy is one of the most closed economies in the developed world. Its limited international trade means total traded goods crossing its border comprise around 18% of GDP. The US is the green line below, compared with the UK, in blue, in the middle of the pack. Imports comprise around 11% of GDP, and of this, imports from Canada, Mexico and China account for around 5% (almost half).

'Bad actors'
The Republican administration has identified a so-called “Dirty 15”, a list of countries with whom they say the US runs big trade deficits. Of Canada, China and Mexico in the chart below however, only China is really what the Nutmeg team might call a ‘bad actor’ (acting badly in terms of trade). China’s imports from the US total only around 30% of its exports to the US. The ratio for Mexico has also deteriorated in the last decade, but it still does not match China. The chart shows that the US has been in a fairly stable trade deficit with these three nations in the last 20 years.

'Big actors' – The companies that have grown beyond US borders
This bad actor argument is far from the whole story though. Looking only at goods exported by US-based companies to overseas markets hugely underplays the impact that US companies, overall, have on the world.

In the chart above, the dotted line shows exports from the US to other countries, as a percentage of total US GDP. The solid black line shows the total sales of multinational US companies, operating overseas, as a percentage of US GDP.
Multinational enterprises (MNEs) are companies that – by definition – have facilities in multiple countries, and in a few cases, all around the world. The goods captured by this sales figure don’t leave the US as exports, but they are still sales by US-owned firms operating overseas.
The chart indicates that these US MNEs sell three times more goods and services than their domestic cousins. When the sales from US-owned, overseas-based production facilities are considered, the impact of US companies in the world is already considerably bigger than the exports figure suggests.
You will notice the lengthy time lag on this officially-reported MNE data; the last update is 2022. Despite this, the chart shows how important good business relations between the US and the rest of the world are.
Ironically, almost half of MNE sales by US-owned companies are European sales. The new Republican institution must know all this, and may adjust its deal-making strategy accordingly.
How will financial markets react to increased US tariffs?
We remain of the view that the US economy is currently strong and that riskier assets like equities will be supported. That being said, investors may not be out of the woods, and some more bouts of volatility seem likely.
The seemingly haphazard way in which tariff threats are being thrown around is unsettling investors everywhere. It’s unwelcome uncertainty in a world where the “status quo” – a sense of normalcy – is so important for long-term investing.
Threats by trading partners to reciprocate with tariffs on US goods will likely have macroeconomic, market and geopolitical implications over the short- to medium-term.
Macroeconomic impact
The scope of tariffs to impact – specifically to increase – inflation, is limited by two factors.
First, any tariffs would need to be introduced over the long-term/permanently to have an inflationary impact. This is not the model being shown by the US president. So far, they have been used to extract better trade deals. Second, because the level of imports into the US is small, the extent to which tariff increases reach the economy should be limited.
Tariffs are a ‘supply shock’. Supply shocks are usually inflationary as they normally adversely impact productivity and wealth creation. Supply shocks refer to any period where the supply of goods and services is restricted artificially (such as by tariffs) or by natural disaster (COVID shutdowns). Prices can rise as more people chase fewer goods and services.
For the US, this adverse productivity shock may be offset by growth-positive factors in the form of reshored supply chains, as some manufacturing returns to the US. Time will tell. There is also some hope that AI may have a game-changing impact on productivity.
For Europe, there are a few encouraging dynamics unfolding that we believe can add to growth, especially the expected rise in defence spending. The ‘peace dividend’ following the early signs of a resolution in Ukraine should help Europe through three channels – lower energy costs, reconstruction work, and higher confidence.
Market impact
The uncertainty has already made things tricky for the policymakers at the Federal Reserve (Fed). The Fed had been in the process of gradually reducing interest rates, typically supportive for economic growth. However, they might have to cut that short – or pause to assess how things play out – in light of the muddied outlook for US inflation.
As we have highlighted, multinational US companies are actively involved in global economies. Many of these are globe-trotting listed companies – the ones you will find in the S&P 500. We see the global economy continuing to grow at a moderate pace, which will support US and global stock markets. Should the president, and this is not our base case, take the tariff war to extremes, a more adverse market environment could ensue.
Geopolitical impact
The US is already in a tech trade war with China. Since around 2017, the US has sought to reduce its dependency on China as a producer of vital technology enabling components like semi-conductors. As a consequence, the US needs as many countries to align with its own technology as possible.
For as long as the US is using threats or the implementation of tariffs as part of its political vision, it provides a platform for China to draw more countries into its technology orbit. With this, the US cedes economic as well as geopolitical power.
Investment portfolio impact
Overall, the Nutmeg investment team is confident that globally diversified investors will find growth opportunities. With the usual patience required of long-term investors, we expect that the short-term uncertainty created by the new US Presidential Administration will pass.
However, investment returns never come without a risk warning; markets go down as well as up. Nutmeg’s investment team currently think the positives outweigh the negatives.
Risk warning
As with all investing, your capital is at risk. The value of your portfolio with Nutmeg can go down as well as up and you may get back less than you invest.
