Retaliation is Likely
If countries with large trade surpluses weaken their currency, countries with large trade deficits are likely to retaliate through reciprocal currency manipulation or trade tariffs.
Source: The Economist

And we know how that game ends. In 1930, following France’s very successful 1928 devaluation and Britain’s tightening of trade conditions within the Commonwealth, the world’s leading trade-surplus nation passed the Smoot-Hawley tariffs in a transparent attempt to gain a greater share of dwindling global demand. This would have been a great strategy for the US had no one noticed or retaliated, but of course the rest of world certainly noticed, and all Smoot-Hawley did was accelerate a collapse in global trade which, not surprisingly, hurt trade surplus countries like the US most.
We seem to be following the same path, and in a beggar-thy-neighbor world any country that does not participate in retaliatory policies will suffer. The only question is which retaliatory policy. I suspect that countries that can intervene in the currency and manipulate domestic interest rates will select those polices as the most efficient way of intervening in trade. Countries that cannot will almost certainly resort to trade tariffs. And it is probably too late for global policy coordination to make much of a difference. It would be very difficult for policy coordination to limit all the many ways countries can and do cheat, and in the end the trade-deficit countries will probably find it easier to retaliate openly and directly. And why not? Diversified countries with large trade-deficits have most of the best cards in any trade dispute. Simple game theory suggests that a sub-optimal result is almost inevitable absent a policeman to bully participants into good behaviour.

On March 10, 2026, India’s Union Cabinet approved amendments to Press Note 3, a regulation that mandated government approval on all foreign direct investment (FDI) from countries sharing a land border with India. This amendment raises questions primarily about whether its stated benefits will materialize and if the risks have been adequately weighed. This piece will address the same.

India and the United States are close to concluding a Reciprocal Defense Procurement Agreement (RDPA) that will allow firms from the two countries to sell to each other’s defense establishments more easily. While this may not remedy the specific grievances both sides may have regarding larger bilateral issues, an RDPA could restore some momentum, following the trade deal announcement.

On the last day of the India AI Impact Summit, India signed Pax Silica, a U.S.-led declaration seemingly focused on semiconductors. While India’s accession to the same was not entirely unforeseen, becoming a signatory nation this quickly was not on the cards either.
