Oil above $104 breaks bond markets and rattles India as the Fed signals more hikes ahead

Oil at $104 is doing something specific to European bond markets, and the mechanism is worth following step by step. When crude prices rise, investors expect consumer prices to rise too, because energy feeds into the cost of almost everything: transport, heating, manufacturing. Central banks respond by keeping interest rates higher for longer to stop that inflation from becoming permanent. Higher rates mean governments pay more to borrow, and bond prices fall as yields, the effective interest rate on a bond, rise to reflect that.

France is the country feeling this most acutely right now, and the reason is its starting position. It is running a large budget deficit, meaning it spends significantly more than it collects in tax, and it needs to borrow heavily from markets to cover the gap. When yields rise across the eurozone, France's spread, the gap between what it pays and what Germany pays, widens because investors see France as a weaker credit. Street protests over school conditions add a political layer: if the government cannot pass a budget, the deficit stays large, and the spread widens further. One month of yield data does not tell us whether France faces a genuine debt crisis, but the direction is uncomfortable.

The RBI's Wednesday hike reversed a cut cycle that had run for over a year, and the reason it reversed is imported inflation. India does not produce enough oil to meet its own needs, so it buys the rest from abroad, priced in US dollars. When Brent rises above $104, every barrel costs more rupees, and that extra cost spreads through the economy via fuel prices, freight costs and food. The RBI cannot drill more oil, but it can raise the repo rate, the rate at which it lends to commercial banks overnight, to make borrowing more expensive across the economy and slow the spending that is pushing prices up.

The problem, and what I find genuinely difficult about this situation, is that the hike is the right tool for domestic demand-driven inflation but a blunt one for oil-driven inflation. If prices are rising because Indians are spending too much, higher rates cool that spending. But if prices are rising because crude costs more on world markets, higher rates do not make oil cheaper. They do help the rupee by making Indian assets more attractive to foreign investors, which reduces the import bill in rupee terms. But Reuters reports today that global yields are rising so fast that India's rate advantage is shrinking anyway, so the outflows continue. The RBI is, in effect, chasing a moving target.

There is a specific concept at work in the inflation expectations number, and it is worth naming: the idea that expectations themselves drive outcomes. If a majority of households believe prices will be 3.9% higher in a year, workers ask for pay rises of at least that size to protect their living standards. Firms, facing higher wage bills, raise their prices to cover costs. The original expectation becomes real, not because anything in the supply chain changed, but because enough people acted on the belief. Economists call this an expectations-anchoring problem: a central bank's main job, beyond setting rates, is to convince people that inflation will return to target so the self-fulfilling cycle never starts.

The Fed's September minutes show officials are not yet convinced expectations are anchored. They see another hike as necessary, even without agreeing on when. That ambiguity is itself a signal: the Fed is keeping its options open, which means markets cannot rule out a hike at any upcoming meeting. For a Paper 1 essay on monetary policy effectiveness, this is a strong example of how the credibility of a central bank, its track record of doing what it says, shapes outcomes independently of the actual rate level. The honest limit here is that one survey reading is not proof of a wage-price spiral; it is a warning sign that the Fed is taking seriously.
