The nominated CEA chair designate, Stephen Miran, has an exposition (h/t Politico) of how protectionism and a depreciating dollar can go together. As far as I can make out, it involves massive forex intervention, possibly sterilized, along with “user fees” on foreign held-UST’s…
Executive Summary
The desire to reform the global trading system and put American industry on fairer ground vis-à-vis the rest of the world has been a consistent theme for President Trump for decades. We may be on the cusp of generational change in the international trade and financial systems. The root of the economic imbalances lies in persistent dollar overvaluation that prevents the balancing of international trade, and this overvaluation is driven by inelastic demand for reserve assets. As global GDP grows, it becomes increasingly burdensome for the United States to finance the provision of reserve assets and the defense umbrella, as the manufacturing and tradeable sectors bear the brunt of the costs. In this essay I attempt to catalog some of the available tools for reshaping these systems, the tradeoffs that accompany the use of those tools, and policy options for minimizing side effects. This is not policy advocacy, but an attempt to understand the financial market consequences of potential significant changes in trade or financial policy. Tariffs provide revenue, and if offset by currency adjustments, present minimal inflationary or otherwise adverse side effects, consistent with the experience in 2018-2019. While currency offset can inhibit adjustments to trade flows, it suggests that tariffs are ultimately financed by the tariffed nation, whose real purchasing power and wealth decline, and that the revenue raised improves burden sharing for reserve asset provision. Tariffs will likely be implemented in a manner deeply intertwined with national security concerns, and I discuss a variety of possible implementation schemes. I also discuss optimal tariff rates in the context of the rest of the US taxation system. Currency policy aimed at correcting the undervaluation of other nations’ currencies brings an entirely different set of tradeoffs and potential implications. Historically, the United States has pursued multilateral approaches to currency adjustments. While many analysts believe there are no tools available to unilaterally address currency misvaluation, that is not true. I describe some potential avenues for both multilateral and unilateral currency adjustment strategies, as well as means of mitigating unwanted side effects. Finally, I discuss a variety of financial market consequences of these policy tools, and possible sequencing.
Dr. Miran also mentions getting the Fed to “cap” interest rate increases. This is because of the recognition that interest rates are a key determinant of the dollar’s value, as I show in this post.
On restructuring the international financial system, count me dubious.
