Few figures in English history represent the triumph of fuzzy myth-making over reality more than Robin Hood. There’s no evidence that he existed, and if he did, I wouldn’t be surprised to learn that in fact he was basically a terrorist while the Sheriff of Nottingham was a hard-working public servant doing a tough job in difficult circumstances. Perhaps that makes Hood an ideal figurehead for the NGO-backed campaign for a financial transactions tax, something which is heavy on symbolism and light on detail.
Debate over the plan – which would impose a small levy on financial transactions to fund domestic public services, and poverty reduction and tackling climate change overseas – has focused on whether it makes financial success. Less discussed is whether the scheme is politically possible or even desirable.

As the campaign website acknowledges a Robin Hood Tax (RHT) “requires co-ordinated implementation by the G20 countries, or at least the G8.” They think this is possible because the international response to the financial crisis demonstrated the “ability of powerful countries to act in unison”. However, during the financial crisis, nations’ immediate interests were all pointing in the same direction. Where states have in recent years tried to coordinate over issues that transcend national interests, the results have been acrimony and deadlock (eg Copenhagen, Doha).

Even if a sufficient number of countries do sign up, some important questions remain unanswered, even unacknowledged. For example, if the RHT is to be a permanent fixture as the campaigners appear to suggest, what would happen if a future government wanted to withdraw? Doing so would destroy the level playing field on which the system depends but locking future governments in would be undemocratic and unconstitutional.

Maintaining the level playing field would also require blocking states from changing unilaterally the size of the levy or the destination of revenues away from frontline public services. According to the website, “all stakeholders would take decisions jointly about collecting and allocating money”. They don’t flag up that this would entail an erosion of national sovereignty on fiscal policy, something about which, in the debate over Europe, the British public has shown it feels strongly.

Similar issues arise when you wonder how the RHT will be enforced. How do you stop some financial regulators being more lax on evasion than others? What if France classified France Telecom and EDF as public services? The task of preventing abuse and ensuring uniform interpretation of key terms would surely require an oversight body capable of overriding national governments and regulators – another big step with profound implications.

Monitoring how revenues earmarked for international development are spent could also be a headache. The campaigners say funds would be managed by “a UN mechanism” and “spent according to developing countries’ own poverty reduction priorities”. As seen at Copenhagen, developing countries are very sensitive about donor states trying to monitor aid outcomes. But donor countries might be accused of unworldliness if they hand over chunks of their national wealth without a say on how it’s spent and no rigorous audit mechanism, especially following the BBC report this week alleging that large amounts of money raised for Live was siphoned off by Ethiopian rebels and spent on weapons.

Then there’s the issue of fairness. Just because something punishes bankers and splurges money on the poor does not mean that it operates fairly. If all stakeholders make decisions “jointly”, even though some countries by virtue of having bigger financial centres contribute far more, is that actually fair? Furthermore, and without wanting to be shunned in left-wing circles, I don’t fully understand why, when clawing back the money sunk into saving our banking sector, the British taxpayer should share a kind of preferred creditor status with governments overseas who had nothing to do with it, or why the government should not be able to spend the money as needs dictate.
“Not complicated. Just brilliant”, is how the campaigners sum up their idea. I politely suggest that they haven’t thought it through.
