When inflation is driven by an oil shock, the Reserve Bank’s usual playbook is to “look through it”.

Because raising the OCR in Wellington won’t reopen the Strait of Hormuz.

It won’t get more oil onto ships. And it won’t bring inflation down overnight. Because it takes time for an OCR increase to flow through the economy and stop the cost of living from going up so fast.

By the time that happens … the strait could be back open and oil prices lower. 

Westpac’s rule of thumb is that every US$10 increase in the oil price adds about 0.1% to 0.2% to inflation in New Zealand. 

So, if oil is up about US$40 a barrel, that implies roughly 0.4% to 0.8% extra inflation.

Inflation had been forecast to ease to about 2.6% by June. Add the extra inflation, and suddenly you’re back at roughly 3.0% to 3.4%.

So some more inflation. But not as much as you might think. 

That’s why the Reserve Bank has to weigh up two competing risks:

  • inflation staying too high for too long, and
  • an already fragile economy getting punched in the face by higher fuel costs

So expect the OCR to stay where it is for at least a few months. We’re unlikely to get a knee-jerk increase.
