0.75% is a record low, but don't think for a second the Reserve Bank has finished cutting the cash rate

  • Written by Peter Martin, Visiting Fellow, Crawford School of Public Policy, Australian National University

Anyone who thought that with the Reserve Bank’s cash rate now close to zero, its run of interest rate cuts was over, needs only to read the last sentence of Governor Philip Lowe’s announcement[1] after Tuesday’s cut:

The Board will continue to monitor developments, including in the labour market, and is prepared to ease monetary policy further if needed to support sustainable growth in the economy, full employment and the achievement of the inflation target over time.

For the longest time, the run of cuts was over.

Lowe’s immediate predecessor, Glenn Stevens, cut the cash rate to a record low of 1.5% in August 2016 as something of a “parting gift”, allowing Lowe to take over and keep it steady, unchanged for a record 34 months.

For most of those three years he made it clear the rate was unlikely to fall further. Six times[2] he said the next move in rates was likely to be up, “rather than down”, pointing to rate increases overseas and progress on jobs and returning Australia’s unusually low inflation rate to his target band.

By February this year he was backtracking[3]. Although it wasn’t apparent in the published figures, the unemployment rate was about to begin climbing. Wage growth had been far weaker than forecast, inflation showed no sign of returning to the centre of his target band, and forecasts for global growth were falling.

The probabilities of next move being up and down had become “more evenly balanced”.

The extra cut announced on Tuesday is because the last two didn’t do enough. House prices have begun to move up (as would be expected with lower rates) but borrowing is growing only slowly, and home building is weak. The Australian dollar is low (in part because of the lower rates), which should help make Australian businesses competitive, but they are not keen to borrow. Since the last Reserve Bank board meeting we have learned that economic growth is shockingly low[7], just 1.4% over the past year, the weakest since the global financial crisis. Household spending is barely keeping pace with population growth. How the cuts will help The cash rate is the rate the Reserve Bank pays banks who deposit with it overnight. It drives almost every other rate, including the rates banks pay retail depositors, which help determine their cost of lending. They don’t have to cut their mortgage and business rates in line with cuts in the Reserve Bank cash rate, but they usually do. The average so-called standard variable mortgage rate is 5.2%, but few new borrowers pay it. The typical discounted rate is 3.46%, and some discounted rates are much lower. HSBC Australia charges 3.17%. If it passes on Tuesday’s cut in full it will charge only 2.92%, offering the first mortgage rate beginning with the number “2” in Australia’s history. There’s every reason to believe that it will help. Even if Australians don’t borrow more to buy houses, they will be able to use the historically cheap credit embodied in their house loans to buy other things, such as solar panels whose payoff period will have shortened dramatically. Since June many mortgage-holders will have saved A$150 on monthly payments. Sure, confidence and decent wage growth would help, but given how indebted many Australians are, low mortgage rates will do quite a bit on their own. Why they’ll continue Governor Lowe made it clear on Tuesday that they will have to stay low for “an extended period”. A signed agreement with the treasurer[8] requires him to keep them low until unemployment falls and inflation and economic growth return to return to normal levels. He would like the government to help by boosting spending. He often mentions spending on infrastructure. But his employment contract requires him to use the cards he has been dealt. If the economy is weak, he is required to boost it using the instruments he has. Read more: Below zero is ‘reverse’. How the Reserve Bank would make quantitative easing work[9] That’s why he says he is prepared “to ease monetary policy further”. If needed, he’ll do it as soon as next month, cutting the cash rate to 0.5%. If more is needed beyond that, he will get ready to use so-called unconventional measures[10] of the kind being used overseas, buying government and corporate bonds in order to force even more money into Australian’s hands. There’s no reason to believe that the tools he has won’t work, and every reason to believe he’ll keep using them.
