Mark Carney leaves his job as Governor of the Bank of England in March, stepping easily into several new positions: notably, U.N. Special Envoy for Climate Action and Finance and special advisor to the British Prime Minister for the Glasgow COP26 conference on climate change in November. More broadly, Carney is moving from the world of central banking and high finance into that of international political activism on climate at the highest U.N. level.
That’s also a move from a world in which he had sustained success and a high reputation—with one significant misstep to which I’ll return—to one in which he wields less expert knowledge and yet is taking on a much more controversial task. And he clearly relishes this more adventurous role in which he seeks to use his experience as a banker to get the international financial system, both central banks and private financial markets, to become engines of climate policy.
In fact he’s been auditioning for this role since his early days in the Bank of England. In 2015 he established an industry-led task force on the disclosure of climate-related financial risks under Michael Bloomberg (a useful ally) under a mandate from G20 ministers. His particular concern has been to seek to persuade, “nudge,” even compel banks, corporations, and other economic actors to integrate climate risks into our understanding of fiduciary duty; managers must incorporate these risks into their prudent management of their clients’ money. Carney himself has warned several times that managers may in future be held to account for energy investments that turn out badly for their clients because they underestimate the market failures of fossil fuels. And he has used his banking leadership to encourage banks and others to write down the values of fossil fuels in their portfolios.
Now, this is a sophisticated version of an argument that has been going the rounds for about fifty years. That argument begins as a claim that managers and markets should take a wider range of factors than profitability and shareholder value into account when making investment and other decisions. What makes Carney’s argument more sophisticated than my crude version here is that he disguises an essentially ethical argument as long-term prudent investment advice (plus warnings that managers who ignore him may face shareholder suits for losing money.)
Milton Friedman was an early critic of this kind of thing when he attacked the highly respectable concept of corporate charitable giving. He was misinterpreted, of course, by those who believed (or pretended to believe) that he was advocating a capitalism red in tooth and claw that was contemptuous of compassion and idealism. One critic at the time dismissed his argument as “romantic brutalism.”
In fact Milton was a kind and beneficent man, but a realist first. His target was what we now call “virtue-signaling” or, to be even more romantically brutalist, virtue-signaling at the expense of other people. If corporate managers wanted to give money to poor villagers in the Third World, or local symphony orchestras, or National Public Radio, they should write cheques to those causes on their own accounts. Their wives could then legitimately boast about these donations at the Annual Planned Parenthood ball.
What they were not entitled to do was to give money belonging to their shareholders to causes of their own choosing. Friedman was not dissing compassion here. Their shareholders might be feeling generous too, conceivably more generous, but towards causes like Wounded Warriors, Mother Teresa’s missions, or Adoption Services. They would have less to give to their favored causes if the corpocrats had siphoned money from their dividends into the Philanthropy Department. (Please switch donations between corporate managers and shareholders if it makes you feel happier with the outcome and with my argument.) And, after all, the money belonged to them.
Managers in corporations, like managers of pension funds vis a vis pensioners, have a fiduciary duty to act in the interests of their shareholders. That obligation is a key restraint which prevents managers looting the funds entrusted to them. It is clear and has legal force. Corporate executives find it irksome, however, because it restricts their freedoms to allocate funds as they might wish. Hence their attraction towards the idea that vaguer responsibilities to several classes of “stakeholders” should replace this clear fiduciary duty to shareholders. With one bound they would be free.
Such notions rest on highly dubious ethical foundations. The Victorians, who invented the Joint Stock Corporation, saw this very clearly. Half of their popular melodrama depict a villainous guardian who seeks to marry a well-endowed ward (no sniggering at the back) in order to get control of her fortune, conceal the fact that he has embezzled half of it, and benefit from the rule that a wife cannot give evidence against her husband. A Victorian audience would hardly have been soothed if, after his exposure, the villain had stepped forward to explain that he had merely redistributed her fortune on charitable grounds that left her comfortably off and lifted scores of the poor out of dire poverty. We can’t justify spending other people’s money on our favored causes because we think the causes are virtuous.
Carney would object here that in expanding the notion of fiduciary duty, he’s not favoring a cause but giving prudent advice that will save investors from foreseeable losses. For that to be true, he would need to have some ability to see the future better than the market. Does he possess that faculty?
That question brings me to my earlier reference of a misstep in Carney’s career. He has been seriously mistaken twice in his forecasts of how the UK economy would perform following Brexit. The first occasion was when he predicted prior to the 2016 referendum that the economy would be badly damaged merely by a No vote in the referendum. In fact, the economy improved and has performed better than its EU neighbors since the vote.
The second occasion was in 2018 when the Bank of England issued predictions on how Brexit itself might damage the UK economy. Paul Krugman, a strong opponent of Brexit, expressed some considerable skepticism about what struck him as exaggerated forecasts in successive tweets. I quote from Krugman's tweetstorm:
These judgments were a win for Krugman over Carney. The Bank’s forecasts were adjusted heavily to make them less Brexit-phobic a short time later.
If Carney lacks a general infallibility, then we need to look at the plausibility of his particular forecasts. He makes two sets of forecasts in this debate. He forecasts that the rise in temperatures is proceeding at a very rapid rate and that the markets for fossil fuels will fall: As the Guardian reported:
Carney said [Greta] Thunberg was right to point out that climate science showed that the world had only eight years of emitting carbon at its current rate if there is to be a 67% chance of limiting the increase in global temperature to 1.5 degrees. “That’s a legitimate point to make,” he said. “There have been many positive contributions from Greta Thunberg.”
That forecast seems to be considerably more precise than most official forecasts of carbon emissions and temperature increases -- a field already distorted by activist scholarship and political alarmism in the direction of exaggeration. UN forecasts themselves offer a range of possible outcomes which indicates uncertainty on the part of forecasters. To assign these kind of numbers -- eight years of continuing carbon emissions leading to a 67 % chance of holding temperature increases to 1.5 degrees -- all this about a process fed by innumerable factors reminds one of the difference between getting something roughly right versus precisely wrong. Such calculations are taking place, moreover, in a public atmosphere in which the speeches of a young adolescent woman are accorded undue weight by policy-makers. As in earlier controversies, such as Lysenkoism in the Soviet Union, we should subject them to firm skepticism.
Yet if these climate forecasts are either exaggerated or simply uncertain, what is the test which would tell us with some reliability that the market demand for fossil fuels is likely to fall along with the value of companies that extract them. It cannot be the additional stress tests or capital requirements that regulators may want the banks to impose on energy companies, for then the regulators would be using their own interventions as the justification for intervening. As yet, however, non-official market participants can’t seem to see spontaneous causes for this threat to the energy sector.
Recently, I wrote an article on Greta and the rise of the Crankocracy here. It concluded: "Could you have a better illustration of the coming crankocracy than the assembled leaders of the world nodding solemnly and applauding timidly as a 17-year-old adolescent condemns them angrily for not halting the medieval plague about to descend on them unless they replace their business suits with sackcloth and ashes?"
I would be distressed to see Mr. Carney join their flagellant ranks. If he does, though, don't ask him for fiduciary advice.
