Hot US inflation drives the dollar to a 19-month high, bond yields rise across Asia, and India's export surge narrows its trade gap

The PPI, a measure of prices at the factory and wholesale level before they reach consumers, matters because it is a leading signal of where consumer inflation is heading. When producers pay more, they tend to pass those costs on. At 6.5%, the US PPI is telling the Fed that price pressures have not cooled, and markets read that as a near-certain December rate hike, possibly a larger one than previously expected. The interest rate is the price the Fed charges banks to borrow overnight, and raising it makes all borrowing more expensive, which is meant to slow spending and bring prices down.

The dollar's rise to a 19-month high is the part that travels furthest. When US rates look set to rise, global investors move money into dollar assets to earn the higher return. That demand pushes the dollar up. A stronger dollar means every other currency buys fewer dollars, so countries that import oil, food or machinery priced in dollars face a higher import bill overnight. For India, which imports roughly 85% of its oil, a stronger dollar directly raises the cost of that oil in rupees, adding to the inflation the RBI is already fighting. One month of PPI data is not proof the Fed will go large in December, but the direction of travel is clear enough that bond markets are not waiting to find out.

What I find worth watching is the Asian bond yield move. When US Treasury yields rise, investors who hold Japanese, South Korean or Indian government bonds can earn a better return by switching to US debt instead. So they sell Asian bonds, prices fall, and yields rise. Higher government borrowing costs in Asia mean less room for those governments to spend on infrastructure or welfare without adding to their deficits. The question this raises for an IB Paper 1 essay is whether a central bank in a small open economy, one that trades heavily with the rest of the world, can ever really set its own interest rate independently when the Fed moves.

A trade deficit is the amount by which a country's imports exceed its exports in value. India has run a persistent trade deficit for decades, mainly because it imports large quantities of oil, electronics and machinery. When the deficit narrows, it means either exports have grown faster than imports, or imports have fallen, or both. October's data shows the first of those: export growth at 29.9% outpaced import growth. That is the more encouraging reading, because it suggests Indian producers are selling more abroad rather than the economy simply buying less.

The $1 trillion export target is ambitious context. India's total merchandise exports were around $450 billion in the 2023-24 financial year, so doubling that in a short period requires sustained growth in sectors like engineering goods, pharmaceuticals and electronics. The October number is one month of data, and the government's own minister is the source of the optimistic framing, so some scepticism is fair. But the direction is real: faster export growth, a narrower deficit, and a moment when the rupee needs every bit of support it can get as the dollar strengthens. Whether October's pace holds through the winter months, when global demand tends to slow, is the question the next two data releases will answer.

The proposed three-way meeting is unusual enough to be worth thinking through carefully. In the normal logic of great-power competition, the US, China and Russia have sharply conflicting interests: over Ukraine, over Taiwan, over trade. A joint summit does not make those conflicts disappear. What it signals is that all three governments see some value in a shared table, whether to manage escalation, to negotiate a Ukraine settlement, or to explore a new set of rules for great-power behaviour. The balance of power, the idea that states act to prevent any single country from dominating the international system, is the lens that fits here: each of the three has an incentive to talk to the others precisely because none wants to be isolated.

The Iran shift is the part with the most immediate economic read. Trump's move from military threat to economic pressure, timed to the midterms, is a classic example of how domestic politics shapes foreign policy. Sanctions, the tool of economic pressure, restrict Iran's ability to sell oil on world markets. Tighter enforcement would reduce Iranian supply and push the oil price up. But the Gulf Arab allies who reportedly want the status quo are also OPEC members who benefit from higher prices. The tension between keeping Iran contained and keeping oil affordable for US consumers is not resolved by the strategy shift, it is just deferred. If you have been following the Hormuz Oil Risk thread, this is the episode where the military risk fades but the sanctions risk quietly rises.

China's proposed curbs are a supply-side shock to the global solar manufacturing industry: a sudden reduction in the availability of a key input, in this case the machines and processes needed to make solar wafers and polysilicon. When a dominant supplier restricts access to technology, the countries that depended on it face a choice: pay more to source from elsewhere, slow their build-out, or develop the technology themselves. All three options are costly. India's 100-gigawatt target was built on the assumption that Chinese technology would remain accessible and cheap. That assumption is now in doubt.

The precedent that comes to mind is the US chip export controls on China, which began in 2022 and have tightened since. China is now doing something structurally similar in a sector where it holds the dominant position. The difference is that solar technology is more widely available than cutting-edge chip manufacturing equipment, so Germany and other European suppliers can partially fill the gap, which is exactly what Indian manufacturers are now exploring. The honest evaluation is that this is early-stage: a proposal, not a policy. But the direction of travel, toward technology becoming a tool of geopolitical competition rather than a freely traded good, is consistent across semiconductors, batteries and now solar. That pattern is worth tracking for anyone writing an extended essay on industrial policy or trade.
