• With a perpetual bond, the principal, or the amount that is borrowed, is never paid back, and the borrower only repays the interest on the bond.
  • Such bonds have been issued during times of crisis before, Soros said, noting that the UK issued perpetual bonds during the Napoleonic Wars.
  • Soros' suggestion comes days after France and Germany proposed a 500 billion ($545 billion) billion recovery fund for the EU which would be funded by grants.
  • Soros said the EU needs to maintain an AAA rating or else bonds will be "unsaleable".

Billionaire hedge-fund founder George Soros thinks Europe can help solve the economic crisis driven by the coronavirus by issuing so-called perpetual bonds, a little used form of bond that has no maturity or end date.

These bonds, also called consols or perpetual bonds, are unique because the principal the amount borrowed is never paid back, and only interest is paid by the issuing party. They must, however, pay that interest in perpetuity.

They've previously been used in times of crisis by governments around the world to fund things like wars.

Soros thinks they could be a handy way of helping governments deal with the economic fallout of the pandemic, which has locked down virtually the whole continent, seen businesses disappear, and millions become unemployed.

In a transcript of a De Telegraaf interview emailed to reporters, the hedge fund veteran and founder of Soros Fund Management said: "They [consols] have a long history in both countries. In the UK they were used, among other things, to finance the wars against Napoleon and to finance the First World War. In the US they were introduced in the 1870s."

How consols work

Soros warns that these bonds should not be mistaken with emergency coronavirus bonds, and pose a more elegant solution to the funding problems faced by European governments.

"The principal amount of a perpetual bond never has to be repaid; only the annual interest payments are due. A 1 trillion ($1.09 trillion) bond would cost 5 billion ($5.45 billion) a year, assuming an interest rate of 0.5%," he said.

Consols do not need to be sold all at once, they can be issued in tranches and can be sold by long-term investors, he said. "As the markets familiarize themselves with the new instruments, later tranches would attract a larger set of buyers and eventually the bonds would fetch a premium," he added. Soros said: "Unfortunately, my suggestion for perpetual bonds has been confused with "corona bonds" and this has poisoned the debate." "The two have nothing to do with each other. Corona bonds have been decisively rejected, and with good reason, given that they require a degree of mutualization that is simply not acceptable." The corona bonds mentioned by Soros are a set of mutualized bonds proposed by numerous European Union nations that would be jointly issued by the European Investment Bank. Spain, Italy, France are among those who have suggested the bonds. How it's different from the recovery fund France, Germany proposed Fine Art / Getty Images France and Germany, the eurozone's two biggest economies proposed a 500 billion ($545 billion) coronavirus recovery fund this week. It was heralded by one analyst as a modern day equivalent of the Marshall plan, the post-World War II economic package designed to save the European economy, according to analysts. But it was based on issuing grants instead of loans, meaning that those given money would never have to pay it back. Soros is suggesting the opposite. "That is why I now speak about "consols." The only mutual obligation is the payment of the annual interest, which is negligible. 5 billion ($5.4 billion) annually secures an urgently required 1 trillion ($1.09 trillion) an amazingly low cost/benefit ratio of 1:200!" he said. What the EU needs to do before it can issue perpetual bonds Soros said that the EU needs to maintain an AAA rating in order for consols to work, otherwise the bonds will be "unsaleable." "That requires the EU to have what is called sufficient 'own resources' taxes that can be levied to cover the cost of servicing the bonds." As imposing taxes can be a long-winded process, Soros said taxes will only need to be authorized not implemented.

"The European Union is particularly vulnerable because it is based on the rule of law and the wheels of justice turn proverbially slowly. By contrast the coronavirus moves very fast and in unpredictable ways," Soros said. "Issuing bonds whose cost/benefit ratio is 1:200 opens up an amazing amount of fiscal space. The money raised does not have to be distributed according to the so-called fiscal key, i.e. member states' shareholding in the ECB. It can be allocated to those in the greatest need."
