RBA's Interest Rate Hike Conundrum: Is It Worth the Economic Cost?

An economics teacher once joked that he set the same exam questions year after year. He changed the answers, however, and that's what central banks could be doing to combat inflation.

The Reserve Bank of Australia (RBA) has been increasing interest rates to curb inflation, but this approach has its drawbacks. According to RBA governor Michele Bullock and Anthony Albanese, they only have one weapon - interest rates - and it might not be effective enough to deal with the current economic difficulties.

A better answer could be for central banks to plead that governments get their budgets in order, reducing the pressure on interest rates. This would also help break the vicious loop of increasing interest rates, leading to higher business input costs, which ultimately makes prices rise.

The RBA increased interest rates from 0.5% to 4.35%, causing unemployment to climb from 3.5% to 4.5%. The Reserve Bank's actions are a big sacrifice to pay on the altar of taming inflation down to 2-3%. However, this approach might be as ineffectual as the Aztecs butchering people atop pyramids in the hope of delivering rain.

Australia's situation is similar to that of the US. In the 2020s, central banks have applied the formula 'increase interest rates to curb inflation,' but this approach leaves them open to criticism for destroying the economy in order to save it from inflation.
