# Moody’s: The Robots Will Do the Work, but the Robots Will Not Go Shopping

*Western populations are about to peak, and the fiscal bill for aging arrives long before the decline actually starts*

## In brief

- Moody’s warns aging populations will strain growth and public finances through pension, care and demand effects
- The EU population is projected to peak as soon as 2029; the US peak could come in 2043 under a low-immigration scenario
- The G7 now has about three working-age people per person over 65, falling to around two by 2050
- Moody’s Chemla calls AI a “partial mitigant”: “robots do not consume – at least not yet”
- China’s over-65 share doubled from 7% to 14% in two decades; Brazil, Thailand and Turkiye show similar trajectories

Here is a slightly unfair trick that demographics plays on governments. You might think the budget problem of an aging population starts when the population starts shrinking. It does not. Moody’s, the credit-rating agency, put out a report last week arguing that the fiscal strain shows up well before the headcount turns down — years of fewer workers, more pensioners and higher care costs, all arriving on the public books while the total population line is still edging upward. The peak is the headline; the dependency ratio is the bill.

The peaks themselves are getting close. The European Commission projects the EU’s population will top out as soon as 2029, “after which a sustained long-term decline will begin.” The US Census Bureau puts the American peak at 2080 under its main projection, or 2043 under a low-immigration scenario — and if you strip out immigration entirely, the US population is already declining. The numbers that matter most to Moody’s, though, are the ratios. Across the G7 economies there are currently about three working-age people for every person over 65. By 2050, that falls to around two.

Think about what that ratio is, mechanically. Three people working, paying taxes, supporting one retiree’s pension and healthcare — shrink that to two, and either each worker pays noticeably more, or the retiree gets noticeably less, or the government borrows the difference. Moody’s assessment is that this puts further pressure on growth and on public finances, including health systems. Olivier Chemla, Moody’s vice president of credit strategy and standards, told CNBC’s “Squawk Box Europe” on Friday that aging works through slower economic growth, rising pension and care costs, changing consumer demand, and shifts in real interest rates and sovereign yields — which is to say, through pretty much every channel a finance ministry cares about.

The report itself is blunt about the arithmetic. “Fewer workers will limit productive capacity, while fewer households and consumers will weaken demand. As a result, countries will have to rely more on productivity to sustain growth.” Population growth, it notes, has long been a tailwind for both growth and creditworthiness; falling fertility and the unprecedented speed of the shift in age structures have now flipped that around.

## The machine that does not shop

The standard reply to all of this — the one you hear at conferences — is that AI and automation will simply make up the missing workers. Chemla’s answer is that this is only half an answer. It is, he said, a “partial mitigant”: you can certainly replace and enhance the supply side of the economy, in factories and services. But, he added, “robots do not consume – at least not yet – and so on the demand side, you will still be having that gap, which will slow growth.” The machines can make the goods. They will not buy them, and until they do, productivity alone cannot close a demand hole.

None of this is only a rich-country problem, and arguably the harder version belongs to poorer ones. China’s share of people aged 65 and over has doubled from 7% to 14% in just two decades, with Brazil, Thailand and Turkiye on similar trajectories. Those countries, Moody’s points out, will face the costs of aging at much lower income levels than the advanced economies that aged before them — the same shift took Europe several decades. Getting old slowly while rich is a budget headache; getting old fast while still getting rich is something else. The costs are concrete and immediate for ordinary households too — American families priced out of formal elder care are already [building granny flats in the backyard](https://rews.cc/a/the-nursing-home-wanted-130-000-a-year-so-the-backyard-got-a-15e29c).

Demography is the rare forecasting exercise where you can see forty years ahead with reasonable confidence, because most of the people who will be drawing pensions in 2050 are already alive and the workers who will fund them, mostly, are too. The interesting question is not whether the bill arrives. It is whether anyone budgets for it before the rating agencies make the point on their letterhead.
