Oil above $100, the ECB hikes again, and New Delhi hosts a fractured BRICS

This story sits squarely in Economics HL, the macroeconomics unit — specifically the section on inflation and the role of central banks. What we have here is a cost-push inflation shock: the supply disruption in the Strait of Hormuz raises oil prices, which shifts the Short-Run Aggregate Supply (SRAS) curve to the left on an AD/AS diagram. The price level rises and real output falls — a combination called stagflation in its more severe form. The ECB's response is to raise the policy interest rate, which works by shifting Aggregate Demand (AD) to the left (higher borrowing costs reduce consumption and investment). In theory this brings inflation down; in practice it also risks deepening any output loss already caused by the supply shock. The causal chain is: Hormuz disruption → oil price spike → higher production costs across all sectors → SRAS shifts left → price level rises → ECB hikes rates → AD shifts left → inflation falls but so does output.

The honest evaluation here is that monetary policy is a blunt instrument against a supply shock. Raising rates cannot pump more oil into the market or reopen the Strait of Hormuz — it only addresses the demand side. A good exam candidate would note the short-run vs long-run distinction: in the short run, higher rates slow demand and may ease price pressure; in the long run, if the conflict ends and supply normalises, the ECB could be left having over-tightened. For India, this matters directly: oil above $100 widens India's current account deficit (India imports roughly 85% of its crude), puts upward pressure on the rupee's exchange rate, and raises the RBI's dilemma between supporting growth and containing imported inflation. This story would make an excellent Economics HL Paper 1 essay on the limitations of monetary policy in response to supply-side shocks, or an IA article given the concrete, data-rich source. The reflective question worth sitting with: if the ECB hikes into a supply shock and growth slows sharply, who bears the cost — and is that the right trade-off?

This is a core Economics HL international trade story. An import ban is the most restrictive form of trade protection — more absolute than a tariff (a tax on imports) or a quota (a numerical limit). Using an import ban rather than a tariff is significant: it signals a political willingness to accept higher domestic prices and potential WTO legal challenges in exchange for maximum leverage. On a standard domestic market diagram, the ban removes the world supply curve entirely for the affected goods, shifting the effective supply curve left, raising the domestic price, increasing producer surplus for US dairy and alcohol producers, and reducing consumer surplus. The net welfare loss (the two deadweight-loss triangles) is the cost borne by society. The causal chain: import ban → domestic supply tightens → domestic price rises → US consumers pay more, US producers gain, net welfare falls.

The counter-argument a strong candidate would raise is about retaliation and trade diversion. Canada is very likely to respond with its own restrictions, which could hurt US exporters — particularly in agriculture and manufacturing — who depend on Canadian market access. There is also a terms of trade angle: if Canada retaliates with tariffs on US goods, the US faces worse terms of trade (it gets less for its exports relative to what it pays for imports). For India, the indirect effect is worth noting: a deepening US–Canada trade war adds to global trade uncertainty, which can dampen FDI flows and slow global growth — both of which affect India's export-oriented sectors. This story is ideal for an Economics HL Paper 2 data-response on trade protection, or as a real-world example in a Paper 1 essay evaluating the costs and benefits of protectionism. The question worth asking: if both countries lose from a trade war, why do governments keep escalating?

This story connects to Global Politics, the power and sovereignty unit, and also to Economics HL, the international economics unit on exchange rates and the international monetary system. The BRICS push to reduce dollar dependence is an attempt to shift the structure of the international monetary system — specifically to challenge the dollar's role as the world's dominant reserve currency. The mechanism matters: most global commodity trade (especially oil) is priced and settled in dollars, which means every country needs to hold dollar reserves to pay for imports. If BRICS members agree to settle trade in rupees, yuan or roubles instead, they reduce that demand for dollars. In Global Politics terms, this is a challenge to US structural power — the ability to set the rules of the international system — rather than just its relational power (direct coercion). The causal chain: BRICS local-currency settlement → reduced global dollar demand → dollar weakens → US loses some leverage over sanctions policy.

The honest limitation here is that currency substitution is very hard in practice. The yuan is not freely convertible, the rupee has capital controls, and no BRICS currency currently has the depth of financial markets that makes the dollar so useful as a reserve asset. A good candidate would note the difference between aspiration and structural reality: BRICS has been talking about de-dollarisation for over a decade with limited concrete progress. The India angle is genuinely complex: India benefits from dollar hegemony in some ways (stable reserve currency, access to US financial markets) even as it chafes at the geopolitical constraints it imposes. The Iran crypto story — $10 billion in crypto adoption as US sanctions cut off traditional banking — is a vivid sidebar showing how actors already try to route around dollar-based financial infrastructure. This story works well as a Global Politics EE topic on the limits of US structural power, or a TOK discussion about whether economic power and political power can really be separated. The question to sit with: can a bloc as internally divided as today's BRICS actually shift the monetary order, or is the summit more about signalling than substance?
