How high inflation and low growth could derail US economy

Enormous pressure is being put on Congress to cut taxes. Politicians want to believe the impact will be contained by revenue from import tariffs, spending cuts and higher growth resulting from tax cuts and deregulation. Yet as foreign investors turn away from the US, putting pressure on inflation and growth, economists at ECR Research lay out the risk.

Metal rail road on bridge

Import tariffs and US public finances have been preoccupying markets lately. There is, incidentally, a link between the two issues, as the budget, which was sent to the Senate for approval at the time of writing, assumes significant revenue from import tariffs. Furthermore, one can argue that the more the US raises tariffs, the more US inflation rises and economic growth declines. This, in turn, widens the public deficit.

Concerning import tariffs, financial markets are increasingly assuming that things will not turn out as badly as feared, where it is presumed that tariffs ultimately end up at levels that cause only limited harm to the US economy. Moreover, the budget includes various tax cuts and substantial deregulation is being pursued. Taken together, prospects for the US economy remain far from poor, according to the markets.

We take a different view.

The US no longer wants to act as the world’s policeman

Following the Second World War, a so-called rules-based world order was established under US leadership: in a wide range of areas, rules were agreed upon between many countries, with the US exercising a high degree of control. This applied to international trade, respect for each other’s borders, troop and aircraft movements, the exchange of various types of data, and so on. As the US remained the only superpower for a long time, it could enforce compliance with the agreed rules with relative ease.

All of this is changing rapidly due to the meteoric rise of China. In addition, both Russia and China are increasingly flouting the rules. Moreover, they are working more and more closely together. Russia has vast amounts of commodities (while China largely controls the processing of critical materials), and China has access to well-trained, relatively low-cost labour and advanced technological expertise.

The bloc around China has become so powerful – both militarily and economically – that the US is no longer able to enforce a wide range of rules on the China bloc. As a result, tensions are rising. This is why Washington is now making two key moves:

  • It wants to shed the obligation to intervene wherever a conflict or war breaks out. As long as no major US interests are directly at stake, America opts to stay on the sidelines where possible.

  • Washington realises that the world may soon be heading towards the formation of two large power blocs: China together with Russia on one side, and the US on the other. Where India and Western Europe will ultimately end up remains unclear.

Each of the major blocs will seek to gain the greatest possible influence in the rest of the world, particularly when it comes to commodities, water and so on. This could lead to serious conflicts.

The conclusion Washington appears to be drawing from this is that it wants to disengage from the rest of the world as far as possible, except in cases where essential US interests are at stake. The top priorities are national security and independence from the rest of the world.

Import tariffs

At this point, the US remains heavily dependent on (Chinese) imports – goods the US cannot easily do without. The most obvious example are the critical raw materials required for the production of modern technological equipment, over which China holds a near-monopoly. Furthermore, there is a wide array of semi-finished products that require advanced technological knowledge and skills; they are far cheaper to produce in China and cannot simply be relocated from China back to the US. It takes years to build the necessary plants in the US, and production would also become far more expensive. It is also uncertain whether the US has enough workers for this, especially considering that many foreigners are being driven out of the country.

Even so, Trump and the team around him believe this must be done. The world is changing in such a way that it is becoming irresponsible for the US to remain heavily dependent on foreign imports. This is why the US is now resorting to the introduction of tariffs and other trade-restrictive measures.

In our view, the focus tends to be too much on the economic consequences of the tariffs – higher inflation and lower economic growth in the US. Many believe this will ultimately force Trump to proceed relatively cautiously with import tariffs. However, we fear that fairly high tariffs are bound to materialise. Needless to say, this will result in damage to the US economy, but according to the Trump team, this is the price that must be paid to guarantee national security. Moreover, this price may turn out to be modest, if we also consider public finances.

US public finances heading for derailment

If developments indeed head in the direction of fairly high tariffs, this would have two major drawbacks as it will reduce purchasing power of US consumers and will cause a lot of uncertainty for businesses as countries will retaliate.

As the import tariffs also push up inflation, the Fed has very limited scope to stimulate the economy monetarily. This will therefore have to be done through fiscal policy. This is precisely what the Trump administration is working on. Enormous pressure is being put on Congress to cut taxes. The question, of course, is to what extent the public deficit can or should be widened further as it already stands at around 6.5% of GDP and interest payments are rising rapidly due to the high interest rates. In any case, many politicians (want to) believe that the deficit can be contained by:

  • Revenue from import tariffs.

  • Spending cuts in a number of areas, such as healthcare and other social expenditures.

  • Higher growth resulting from tax cuts and deregulation.

High inflation and low growth

The key question is whether the course mapped out by Washington will succeed. We have serious doubts about this. Foreign investors must finance a significant portion of the large budget and current account deficits. Yet they are becoming increasingly reluctant to invest large sums in the US. If Trump continues to turn against foreign countries and court rulings go unheeded, who says that foreign assets will not be frozen or even confiscated? Less capital flow to the US means more downward pressure on the dollar and more upward pressure on US interest rates. Combined with more uncertainty and the loss of purchasing power owing to import tariffs, this could culminate in lower growth or even a recession. In that case, asset prices would decline sharply, triggering a negative spiral.
