The climate & deflation

Responsive

In income-constrained economies demand seems to have become more responsive to even modest price increases. In Australia, for instance, retail food prices have risen strongly in 2019, primarily due to drought. The net result has been a further decline in the growth of real retail expenditure.

While a city running out of water might raise the price of water (in Chennai the cost of water more than doubled), it’s hard to believe the full effects of such an outcome would be anything other than deflationary as the city’s social fabric comes under stress.

Economists can be somewhat evangelical of a carbon tax as the best policy to address climate change. But, as of 2019, only 57 governments at either a country or regional level have enacted some form of carbon price. More to the point, “only 20 percent of global GHG emissions are covered by a carbon price and less than 5 percent of those are currently priced at levels consistent with reaching the temperature goals of the Paris Agreement,” according to the World Bank.

Rather, much of the policy effort across countries is going into making climate-friendly activities more cost effective, rather than making climate-harming activities less cost effective. Electric vehicles, recycling and renewable energy all feature.

Critically, most renewable energy sources now lie within the fossil-fuel cost range. On the expectation ongoing improvements will bring down prices, further shifts to renewable sources of electricity generation are likely.

This is causing important secular shifts as the dominant forms of energy are being left behind. Consider in 2018 more coal-generated electricity capacity was shut down than was approved, “almost certainly the first time this has happened in a generation, and possibly the first time since the 19^th century”. According to the International Energy Agency new investment in coal has fallen around 75 per cent over the last decade.

Oil prices are also likely to be negatively affected, with peak demand having taken over from peak supply as the most important coming secular shift. Oil prices are a large (often the largest) driver of headline inflation rates.

Impact

The view of climate change as inherently inflationary is also being challenged by some of its human impacts. Climate-related migration has become a prominent concern, with “the Asia-Pacific region acutely vulnerable”. This is not just due to sea level rises, but also the threats to food supply, and the societal impacts that unfold.

Even consider the issue more granularly; Global Health Alliance Australia has suggested rates of food poisoning and workplace absenteeism from heat-related illnesses will rise.

As insurers and financial services use better data to reprice climate-related exposure, some may find the cost of insurance is just too high and forgo cover. Economic activity is likely to naturally gravitate away from those areas.

Climate change and economics are inextricably linked. For instance much of the rise in US emissions before 2007, and then decline to 2009, was driven by the economic cycle. Many parts of the world are only now recognising longer-lived secular stagnation is not just a European or Japanese problem.

And yet we are now closer to the Paris agreement’s 2030 target than to the beginning of the global financial crisis in 2007. The effects of the crisis still linger and in some areas climate-related activity will reinforce them.
