Bitcoin revolution is a matter of trust

One of the more interesting recent developments in finance has been the creation of Bitcoin and other crypto-currencies. They are being touted as a revolution in how we think and use money; characterised as an internet of money to accompany the internet of information. It is certainly futuristic.

BitcoinAlternately, there are many who want to go in the opposite direction — return to the past. This group argues we should go back to the gold standard that was dismantled by Richard Nixon in 1971, mainly in response to the soaring cost of the Vietnam War.

Returning to the gold standard is seen by this group as a way to solve the problem of soaring global debt levels, which are out of control. The global stock of debt is about $US200 trillion, the equivalent of 230 per cent of global GDP.

Both sides have a common enemy: what they call fiat money. This is money whose credibility and value is determined by government dictate (fiat). Allowing governments to dictate in this way, both sides argue, is the core of the problem.

To a significant extent, both sides are wrong. For one thing, private banks, not governments, create most money. As economist Nicholas Gruen has argued we would have far fewer problems if central banks were to create money instead.

Worse, in recent years the problem has been not so much government fiat as the lack of government fiat — or what is known in financial circles as 'deregulation'. For about three decades, the mantra to 'deregulate' the financial markets has been deafening — and successful. Governments progressively withdrew from the financial markets, allowing traders to make up new forms of money.

These were known as derivatives. In effect, they were 'derived' from traditional forms of money (which continued to be subject to government fiat or regulation). The global stock of derivatives, according to the Bank for International Settlements, is now over $US750 trillion. To give some idea of how that compares, the global value of cash is about $US31 trillion; the world's gold stocks are worth about $US8 trillion and the market capitalisation of the world's stock markets is about $US68 trillion.

It is a mess. So where is it headed? To get a sense of that, we first need to understand what money is. Since Henry VIII reduced the amount of gold and silver in the mid-16th century (known as The Great Debasement), money has been more a symbol of value rather than something of worth in itself. Now, it is mostly just blips on a computer network, data.

 

"Crypto-currencies are still in their infancy. But there is little doubt that they will eventually change how we think of money."

 

The question is what makes people trust the symbol? The gold standard worked because people trust that gold is always precious. Physical cash is considered of value because people trust that its worth is government guaranteed (that is, fiat). The derivatives market functions because the traders trust in each other, although this broke down spectacularly in 2008, nearly destroying trust in the world's financial system.

Crypto-currencies like Bitcoin seem to have a genuinely new approach to the issue of trust. Proponents say that it is a 'trustless' system. Although this is not quite right — what they seem to mean is that it does not rely on human trust — it is crucial to why it is significant.

Bitcoin is based on mathematics. More specifically, it is based on a solution to what is known as the 'two generals' problem. Imagine two generals must attack a castle together if they are to win a battle. But they must do so via intermediaries who cannot be trusted. How do they know that the message has got through? In other words, how do they get rid of the middleman?

An ingenious mathematical solution was devised to this puzzle that makes it unnecessary to trust intermediaries. This mathematics forms the basis of the blockchain: the ceaseless calculations that drive the heavily decentralised Bitcoin network.

Trusting maths is a lot less risky than trusting human institutions, but there are a number of questions yet to be convincingly answered. The Bitcoin network is tiny; it is only worth about $US40 billion, a fraction of the cash in the world system. It seems unlikely that it will be possible to achieve the required scale to make it a true global currency. Already, there are growing problems of inefficiency.

Still, the basic ideas — removing financial intermediaries, using the collective intelligence of a decentralised global network, and questioning why governments should be respected when they have vacated their obligation to govern — seem defensible enough.

Crypto-currencies are still in their infancy. But there is little doubt that they will eventually change how we think of money.

I am not quite sure what the central point of this article is. yes, I see that the Bitcoin market is one of the latest forms of disruptive enterprises that now assail us- like Uber , and indeed the internet itself has been. But "trusting maths is a lot less risky than trusting human institutions"? Isn't the bitcoin system a form of institution operated by humans? Perhaps the real question is not why trust it, but why trust it as an alternative to what we already have? Actually ALL money and forms of currency only work becasuse of trust, something that few people I think are conscious ofg. Thus, a cheque is a promise to someone that when you present it to a bank (or someone else) they will give you cash for it; a bank note opertates similarly, albeit backed by government authority. Is it really that bitcoin wil only thrive among the affluent, who have sufficient surplus assets to afford to bypass the established systems. On the other hand, what would happen if the bitcoin mandarins failed to honour transactions? How are they accountable?

I do not think banks create money. They create loans, which are credits on the lenders' books and debits on the borrowers' books, totalling zero. Indeed in the normal course of events, a lending institution is required to maintain a "statutory reserve deposit" to offset a proportion of the money they have loaned or a "capital requirement" to limit the leverage of their loans. It may be that derivatives are a way of avoiding or hiding from such imposed limits, but I don't know. Our current problem is that many governments, ours included, are trying to run surpluses, in the mistaken belief that we cannot afford to run deficits. This policy limits economic growth and leads to low wages and unemployment. What really needs to be controlled is not the amount of spending, but the misspending - allowing companies to get away without paying taxes for using our resources, funding the rich, failing to support the health system, education system etc. etc. Not paying taxes give Google, Amazon and the like a competitive advantage over those who do pay their taxes, and we miss the economic growth otherwise available.

What lies beneath the finance industry's water words

Paper boatOne thing that is rarely done is a literary-style analysis of the language used in finance and business. It can quickly reveal the sleight-of-hand, even outright deception, that plague these powerful sectors. To take one example, finance language heavily relies on water metaphors, which are deeply misleading. It is unlikely that this is done deliberately; it is more probably reification (making the intangible appear to be concrete). But its consequences have been, and remain, devastating.


Budget's bank slug flouts the property precipice

Banks logosThe $6.2 billion the government will raise through a levy on bank liabilities not only shows how out of favour banks have become, it is also, in effect, a de facto tax on property lending - a counterbalance to negative gearing and capital gains tax breaks. It is a tax on property lending because nearly all the banks' loans are mortgages for housing, or business loans secured with property. Of course the banks will pass the extra cost on to their customers, so it becomes a tax on borrowers.

Millennial and Boomer badger money-focused Senior Manager. Cartoon by Chris JohnstonKids these days. We can't hold down a job, we expect to be promoted before we've proven ourselves and we put our career needs before the needs of an organisation. We're the largest age group, making up 37 per cent of the Australian workforce, yet we're expected to shut up and wait our turn. What is it about millennials that has everyone scared? People claim the stereotype is based on generational cohort, not age. But for young Australians in the workforce, they are one and the same thing.


Beyond fake news lies the fog of fake figures

GDPFake news aside, increasingly, we live in a world of fake figures. There is a cliche in management that 'what gets measured gets done'. In public discourse that might be translated to 'what gets measured is considered real'. One obvious fake figure is GDP, which is taken as a measure of national wellbeing. In fact, it is just a measure of transactions. If money changes hands because something disastrous happens then GDP will rise. That is hardly an indicator of national wellbeing.


The language of exploitation in the online labour market

Deliveroo bicycle delivery personWhen you are in the business of exploiting people, language matters. A recently leaked document from Deliveroo is geared to emphasising that the people who deliver food for Deliveroo are and should remain independent contractors, not employees. In 2016, a Unions NSW report into the employment practices of gig-economy company AirTasker categorised the online labour market as 'unregulated Taylorism within a Dickensian marketplace where workers compete for bite-sized fragments of labour'.
