Betting on climate change

A blue-sky proposal by an Asian investment bank raises questions of propriety.

It seems like this is the sort of thing that gets the finance industry a bad name:

A financial product could be constructed with payments linked to a sea-level index, and featuring some characteristics similar to a catastrophe bond or weather derivative...

Protection would come in the form of a higher payment to the policyholder if the sea level rises more quickly than expected and a lower or zero payment if the sea level rises less quickly. Some creativity would be needed to make such a product acceptable to both the policyholder and insurer, but it is quite feasible.

But quite apart from the questionable PR which would result from creating such a product, it probably wouldn't work, as alphaville point out:

In terms of getting the technicals of the product down pat, well why not. But thinking about it – you (as the insurer) would be selling insurance on a potentially massive, truly systemic risk here. Something that could – over time – remove island nations from the map altogether. Not something you can hide from using the law of large numbers, quite possibly.

The chart accompanying the original study shows that 37.2 million people in India alone are at risk from sea-level rises by 2050, and well over 100 million in Asia alone -- as well as another 8 million in the USA. It is likely global catastrophe of that level isn't something the world financial system could escape unscathed, so while the creator of these bonds would make a nice income in the years leading up to disaster -- and an even nicer one if climate change was indeed averted -- anyone expecting that the insurance they had purchased would actually protect them against anything would be in for a nasty surprise. Almost as nasty as the people living in coastal areas.

The Tories have missed a chance to show that they care about student debt

After condemning Jeremy Corbyn for his "betrayal", the government has still raised the top student interest rate to 6.1 per cent. 

For weeks, the Conservatives have assailed Jeremy Corbyn for his alleged betrayal over student debt. The Labour leader told NME during the campaign that he would "deal with" the issue. But he later clarified that this did not amount to a "commitment" to wipe out student debt (which would cost around £100bn) and that he had been "unaware of the size of it at the time". For this, the Tories have accused him of Clegg-style hypocrisy. 

There is little sign, however, that the attack has proved effective. Labour’s manifesto said nothing on the subject of student debt and Corbyn's language in the NME interview was ambiguous. "I’m looking at ways that we could reduce that [student debt], ameliorate that, lengthen the period of paying it off," he said. There is no comparison with the Liberal Democrats, who explicitly vowed not to raise tuition fees before trebling them to £9,000 as part of the coalition. Young voters still credit Corbyn for his vow to abolish tuition fees (were he to break this promise in power, it would be a different matter). 

A further problem for the Tories is that they have spotlighted a problem - student debt - without offering any solution. At present, graduates pay a marginal tax rate of 41 per cent on earnings over £21,000 (20 per cent income tax, 12 per cent national insurance and 9 per cent student loan repayment). This, combined with the average debt (£50,800), leaves them struggling to save for a home deposit, or even to pay the rent. The Conservatives, unsurprisingly, are unable to sell capitalism to voters with no capital. 

Yet rather than remedying this problem, the government has compounded it. The Department of Education has ruled out reducing the top interest rate on student loans from 6.1 per cent, meaning the average student will accrue £5,800 in interest charges even before they graduate.

By maintaining the status quo, the Tories have missed a chance to demonstrate that they have learned from their electoral humbling. Had they reduced student debt, or cut tuition fees, they could have declared that while Corbyn talks, they act. Instead, they have merely confirmed that for graduates who want change, Corbyn remains their best hope.
