Bubbling bitcoin

What do tulips, nickel mining in Australia, South Seas trading, Beanie Babies and cryptocurrencies have in common? The answer is that they have all been the subject of speculative bubbles. In the first four cases the bubble burst. A question currently being asked is whether it will happen to bitcoin.

Bitcoin
Bitcoin was created in 2009 by an unknown person, or people, using the alias Satoshi Nakamoto. It is a digital currency in the form of a line of computer code. Bitcoins are like ‘electronic cash’ which can be held or used for transactions, with holdings and transactions heavily encrypted for security – hence it is a form of ‘crytocurrency’. People can buy and sell bitcoins for normal currencies as well as using them for transactions. People’s holdings are held in electronic ‘wallets’ and can be accessed on their computers or phones via the Internet. Transfers of bitcoins from one person or organisation to another are recorded in a public electronic ledger in the form of a ‘blockchain‘.

The supply of bitcoins is not controlled by central banks; rather, it is determined by a process known as ‘mining’. This involves individuals or groups solving complex and time-consuming mathematical problems and being rewarded with a new block of bitcoins.

The supply of bitcoins is currently growing at around 150 per hour and the current supply is around ₿16.7 million. However, the number of new bitcoins in a block is halved for every 210,000 blocks. This means that the rate of increase in the supply of bitcoins is slowing – the number generated being halved roughly every four years. The supply will eventually reach a maximum of ₿21 million, probably sometime in the next century, but around 99% will have been mined by around 2032.

The bitcoin bubble
The price of bitcoins has soared in recent months and especially in the past two. On 4 October, the price of a bitcoin was $4226; by 7 December it was nearly four times higher, at $16,858 – a rise of 399% in just nine weeks. Many people have claimed that this is a bubble, which will soon burst. Already there have been severe fluctuations. By December 10, for example, the price had fallen at one point to $13,152 – a fall of nearly 22% in just two days – only to recover to over $15,500 within a few hours.

So what determines the price of bitcoin? The simple answer is very straightforward – it’s determined by demand and supply. But what has been happening to demand and supply and why? And what will happen in the near and more distant future?

As we have seen, the supply is limited by the process of mining, which allows a relatively stable, but declining, increase. The explanation of the recent price rise and what will happen in the future lies on the demand side. Increasing numbers of people have been buying bitcoin, not because they want to use it for transactions, whether legitimate or illegal over the dark web, but because they want to invest in bitcoin. In other words, they want to hold bitcoin as an asset which is increasing in value. These people are known as ‘hodlers’ – a deliberate misspelling of ‘holders’.

But this speculation is of the destabilising form. The more prices have risen, the more people have bought bitcoin, thus pushing the price up further. This is a classic bubble, whereby the price does not reflect an underlying value, but rather the exuberance of buyers.

The problem with bubbles is that they will burst, but just when is virtually impossible to predict with any accuracy. If the price of bitcoins falls, what will happen next depends on how the fall is interpreted. It could be interpreted as a temporary fall, caused by some people cashing in to take advantage of the higher prices. At the same time, other people, believing that it is only a temporary fall, will rush to buy, snapping up bitcoins at the temporary low price. This ‘stabilising speculation’ will move the price back up again.

However, the fall in price may be seen as the bubble bursting, with even bigger falls ahead. In this case, people will rush to sell before it falls further, thereby pushing the price even lower. This destabilising speculation will amplify the fall in prices.

But even if the bubble does burst, people may believe that another bubble will then occur and, once they think the bottom has been reached, will thus start buying again and there will be a second speculative rise in the price.

The crash could be very short-lived. This happened with the second biggest cryptocurrency, Ethereum. On 21 June this year, the price at the beginning of the day was $360. It then began to fall during the say. Once its price reached $315, it then collapsed by 96% to $13 with massive selling, much of it automatic with computers programmed to sell when the price falls by more than a certain amount. But then, on the same day, it rebounded. Within minutes it had bounced back and was trading at $337 at the end of the day. It is now trading at around $450 – up from around $300 four weeks ago.

Whether the bubble in bitcoin has more to inflate, when it will burst, and when it will rebound and by how much, depends on people’s expectations. But what we are looking at here is people’s expectations of what other people are likely to do – in other words, of other people’s expectations, which in turn depend on their expectations of other people’s expectations. This situation is known as a Keynesian Beauty Contest (see the blog, A stock market beauty contest of the machines). Perhaps we need a crystal ball.

The housing market: feeling the pinch

According to the Halifax house price index, house prices fell in the UK in the three months to April. This is the first quarterly fall since 2012. The Nationwide index (see below), shows that prices in April were 0.4% lower than in March (although the 3-month rate was still slightly positive).

The fall in house prices reflects a cooling in demand. This, in turn, reflects a squeeze on household incomes as price rises begin to overtake wage rises. It also reflects buyers becoming more cautious given the uncertainty over the nature of the Brexit deal and its effects on the economy and people’s incomes.

The fall in demand is also driven by recent Bank of England rules which require mortgage lenders to limit the proportion of mortgages with a mortgage/income ratio of 4.5 or above to no more than 15% of their new mortgages. It is also affected by a rise in stamp duty, especially on buy-to-let properties.

Despite the fall in prices, this may understate the fall in demand relative to supply. House price movements often lag behind changes in demand and supply as people are reluctant to adjust to equilibrium prices. In the case of a falling market, sellers may be unwilling to sell at the lower equilibrium price, believing that a lower price ‘undervalues’ their property. Indeed, they may not even put their houses on the market. This makes prices ‘sticky’ downwards. The result is a fall in sales.

Eventually, such people will reluctantly be prepared to accept a lower price and prices will thus fall more. Once people come to expect price falls, supply may increase further as vendors seek to sell before the price falls even more. So we could well see further falls over the coming months.

Lower house prices and falling sales is a picture repeated in many parts of the UK. It is particularly marked in central London. There, estate agents have begun to offer free gifts to purchasers. As The Guardian puts it:

London estate agents have begun to offer free cars worth £18,000, stamp duty subsidies of £150,000, plus free iPads and Sonos sound systems to kickstart sales in the capital’s increasingly moribund property market. The once super-hot central London market has turned into a ‘burnt-out core’ according to buying agents Garrington Property Finders, prompting developers to offer ever greater incentives to lure buyers.

… Land Registry figures show that in the heart of the city’s financial district, average property prices plummeted from £861,000 at the time of the EU referendum to £773,000 in February, a decline of 15%, although in London’s outer boroughs prices are still up over the year.

But lower property prices are good news for first-time buyers, although some of the biggest falls have been in the top end of the market.

The fall in property prices may continue for a few months. But population is rising, and with it the number of people who would like to buy their own home. Once real incomes begin to rise again, therefore, demand is likely to resume rising faster than supply. When it does, house prices will continue their upward trend.

A falling pound – rebalancing the balance of payments

In a recent blog, Falling sterling – bad for some; good for others, we looked at the depreciation of sterling following the Brexit vote. We saw how it will have beneficial effects for some, such as exporters, and adverse effects for others, such as consumers having to pay a higher price for imports and foreign holidays. The article linked below examines these effects in more depth.

Just how much the quantity of exports will increase depends on two main things. The first is the amount by which the foreign currency price falls. This depends on what exporters choose to do. Say the pound falls from €1.30 to €1.18. Do exporters who had previously sold a product selling in the UK for £100 and in the eurozone for €130, now reduce the euro price to €118? Or do they put it down by less – say, to €125, thereby earning £105.93 (£(125/1.18)). Their sales would increase by less, but their profit margin would rise.

The second is the foreign currency price elasticity of demand for exports in the foreign markets. The more elastic it is, the more exports will rise for any given euro price reduction.

It is similar with imports. How much the sales of these fall depends again on two main things. The first is the amount by which the importing companies are prepared to raise sterling prices. Again assume that the pound falls from €1.30 to €1.18 – in other words, the euro rises from 76.92p (£1/1.3) to 84.75p (£1/1.18). What happens to the price of an import to the UK from the eurozone whose euro price is €100? Does the importer raise the price from £76.92 to £84.75, or by less than that, being prepared to accept a smaller profit margin?

The second is the sterling price elasticity of demand for imports in the UK. The more elastic it is, the more imports will fall and, probably, the more the importer will be prepared to limit the sterling price increase.

The article also looks at the effect on aggregate demand. As we saw in the previous blog, a depreciation boosts aggregate demand by increasing exports and curbing imports. The effects of this rise in aggregate demand depends on the degree of slack in the economy and the extent, therefore, that (a) exporters and those producing import substitutes can respond in terms of high production and employment and (b) other sectors can produce more as multiplier effects play out.

Finally, the article looks at the effect of the depreciation of sterling on asset prices. UK assets will be worth less in foreign currency terms; foreign assets will be worth more in sterling. Just how much the prices of internationally traded assets, such as shares and some property, will change depends, again, on their price elasticities of demand. In terms of assets, there has been a gain to UK balance sheets from the depreciation. As Roger Bootle says:

Whereas the overwhelming majority of the UK’s liabilities to foreigners are denominated in sterling, the overwhelming bulk of our assets abroad are denominated in foreign currency. So the lower pound has raised the sterling value of our overseas assets while leaving the sterling value of our liabilities more or less unchanged.

Will there be an oil price rebound?

People are beginning to get used to low oil prices and acting as if they are going to remain low. Oil is trading at only a little over $30 per barrel and Saudi Arabia is unwilling to backtrack on its policy of maintaining its level of production and not seeking to prevent oil prices from falling. Currently, there is still a position of over supply and hence in the short term the price could continue falling – perhaps to $20 per barrel.

But what of the future? What will happen in the medium term (6 to 12 months) and the longer term? Investment in new oil wells, both conventional and shale oil, have declined substantially. The position of over supply could rapidly come to an end. The Telegraph article below quotes the International Energy Agency’s executive director, Fatih Birol, as saying:

“Investment in oil exploration and production across the world has been cut to the bone, falling 24% last year and an estimated 17% this year. This is… far below the minimum levels needed to keep up with future demand. …

It is easy for consumers to be lulled into complacency by ample stocks and low prices today, but they should heed the writing on the wall: the historic investment cuts raise the odds of unpleasant oil security surprises in the not too distant future.”

And in the Overview of the IEA’s 2016 Medium-Term Oil Market Report, it is stated that

In today’s oil market there is hardly any spare production capacity other than in Saudi Arabia and Iran and significant investment is required just to maintain existing production before we move on to provide the new capacity needed to meet rising oil demand. The risk of a sharp oil price rise towards the later part of our forecast arising from insufficient investment is as potentially de-stabilising as the sharp oil price fall has proved to be.

The higher-cost conventional producers, such as Venezuela, Nigeria, Angola, Russia and off-shore producers, could take a long time to rebuild capacity as investment in conventional wells is costly, especially off-shore.

As far as shale oil producers is concerned – the prime target of Saudi Arabia’s policy of not cutting back supply – production could well bounce back after a relatively short time as wells are re-opened and investment in new wells is resumed.

But, price rises in the medium term could then be followed by lower prices again a year or two thereafter as oil from new investment comes on stream: or they could continue rising if investment is insufficient. It depends on the overall balance of demand and supply. The table shows the IEA’s forecast of production and consumption and the effect on oil stocks. From 2018, it is predicting that consumption will exceed production and that, therefore, stocks will fall – and at an accelerating rate.

But just what happens to the balance of production and consumption will also depend on expectations. If shale oil investors believe that an oil price bounce is temporary, they are likely to hold off investing. But this will, in turn, help to sustain a price bounce, which in turn, could help to encourage investment. So expectations of investors will depend on what other investors expect to happen – a very difficult outcome to predict. It’s a form of Keynesian beauty contest (see the blog post A stock market beauty contest of the machines) where what is important is what other people think will happen, which in turn depends on what they think other people will do, and so on.

When pessimism takes over

Over 2015 quarter 3, stock markets around the world have seen their biggest falls for four years. As the BBC article states: ‘the numbers for the major markets from July to September make for sobering reading’.

  US Dow Jones: –7.9%
  UK FTSE 100: –7.04%
  Germany Dax: –11.74%
  Japan Nikkei: –14.47%
  Shanghai Composite: –24.69%

So can these falls be fully explained by the underlying economic situation or is there an element of over-correction, driven by pessimism? And, if so, will markets bounce back somewhat? Indeed, from 30 September to 2 October, markets did experience a rally. For example, the FTSE 100 rose from a low of 5877 on 29 September to close at 6130 on 3 October (a rise of 4.3%). But is this what is known as a ‘dead cat bounce’, which will see markets fall back again as pessimism once more takes hold?

As far as the global economic scenario is concerned, things have definitely darkened in the past few months. As Christine Lagarde, Managing Director of the IMF, said in an address in Washington ahead of the release of the IMF’s 6-monthly, World Economic Outlook:

I am concerned about the state of global affairs. The refugee influx into Europe is the latest symptom of sharp political and economic tensions in North Africa and the Middle East. While this refugee crisis captures media attention in the advanced economies, it is by no means an isolated event. Conflicts are raging in many other parts of the world, too, and there are close to 60 million displaced people worldwide.

Let us also not forget that the year 2015 is on course to be the hottest year on record, with an extremely strong El Niño that has spawned weather-related calamities in the Pacific.

On the economic front, there is also reason to be concerned. The prospect of rising interest rates in the United States and China’s slowdown are contributing to uncertainty and higher market volatility. There has been a sharp deceleration in the growth of global trade. And the rapid drop in commodity prices is posing problems for resource-based economies.

Words such as these are bound to fuel an atmosphere of pessimism. Emerging economies are expected to see slowing economic growth for the fifth year in succession. And financial stability is still not yet assured despite efforts to repair balance sheets following the financial crash of 2008/9.

But as far as stock markets are concerned, the ECB is in the process of a massive quantitative easing programme, which will boost asset prices, and Japan looks as if it too will embark on a further round of QE. Interest rates remain very low, and, as we discussed in the blog Down down deeper and down, or a new Status Quo?, some central banks now have negative rates of interest. This makes shares relatively attractive for savers, so long as it is believed that they will rise over the medium term.

Then there is the question of speculation. The falls were partly due to people anticipating that share prices would fall. But has this led to overshooting, with prices set to rise again? Or, will pessimism set in once more as people become even gloomier about the world economy? If only I had a crystal ball!

The Shanghai Stock Exchange: a burst bubble?

Many Chinese people have taken to investing on the Chinese stock market, seeing it as a way of making a lot of money quickly. From October 2014 to June this year the market soared, rising by 126% from 2290 to 5166.

More and more people used their savings to buy stocks and China now has over 90 million individual investors. And it was not just savings that were invested. Increasingly people have been borrowing money to invest, seeing it as an easy way of making money. Unlike stock markets in developed countries, where the majority of shares are held by financial organisations, such as pension funds, holdings by individuals account for about 80% of stocks on the Chinese market.

But since mid-June, share prices have plummeted by 32% (see chart). People have thus seen a huge fall in the value of their savings, while many others have found their shareholdings worth less than their debts. The fall, like the rise that preceded it, has been driven by speculation, fuelled by first optimism and then pessimism.

The Chinese government is worried that the fall might dampen investment and economic growth. It has thus has been supplying liquidity to various institutions to buy shares, but this has had little effect and is dismissed by many as meddling. What is more it could expose companies which take advantage of the liquidity to greater risk.

So serious has been the rout, that over 50% of listed companies have halted trading on the mainland Chinese stock exchanges.

So just why has there been this bubble and why has it burst? What implications will it have for (a) China and (b) the rest of the world? The following articles explore the issues.

Pound appreciates as chances of more QE decline

In an interview with the Yorkshire Post, Mark Carney, Governor of the Bank of England, said that under current circumstances he did not feel that further quantitative easing was justified. He said:

My personal view is, given the recovery has strengthened and broadened, I don’t see a case for quantitative easing and I have not supported it.

In response to his speech, the pound strengthened against the dollar. It appreciated by just over 1 cent, or 0.7%. But why should the likelihood of no further quantitative easing lead to a strengthening of the pound?

The answer lies with people’s anticipation of future interest rates. If there is no further increase in money supply through QE, interest rates are likely to rise as the economy recovers and thus the demand for money rises. A rise in interest rates, in turn, is likely to lead to an inflow of finance into the country, thereby boosting the financial account of the balance of payments. The increased demand for sterling will tend to drive up the exchange rate.

However, an increase in aggregate demand will result in an increase in imports and a likely increase in the balance of trade deficit. Indeed, in July (the latest figures available) the balance of trade deficit rose to £3.085bn from £1.256bn in June. As recovery continues, the balance of trade deficit is likely to deteriorate further. Other things being equal, this would lead to a depreciation of the pound.

So if the pound appreciates, this suggests that the effect on the financial account is bigger than the effect on the current account – or is anticipated to be so. In fact, given the huge volumes of short-term capital that move across the foreign exchanges each day, financial account effects of interest rate changes – actual or anticipated – generally outweigh current account effects.

The brutal face of supply and demand

Stock markets have been plummeting. The FTSE 100 index was 6055 on 7 July 2011; by 10 August, it was 17% lower at 5007. Since then it has risen as high as 5418, but by 13 September was down to 5092. Other stock markets have fared worse. The French index fell 30% between early July and September 13, and the German DAX index fell 32% over the same period.

These falls in share prices reflect demand and supply. Investors are worried about the future of the eurozone and the health of the European economy as Greek default looks more and more likely and as the debts of various other European countries, such as Portugal, Ireland and Spain, seem increasingly unsustainable in an environment of sluggish economic growth. They are also worried about high public-sector debt in the USA and the likelihood that global recovery will peter out.

The ‘bear’ market (falling share prices) reflects increased selling of shares and a lack of demand. Not only are investors worried about the global economy, they are also speculating that share prices will fall further, thereby compounding the falls (at least until the ‘bottom’ is reached).

But why have share prices fallen quite so much? And does it matter to the general public that this is happening? The following articles seek to answer these questions.

Riding the commodities Big Dipper

Anyone investing in commodities over the past few weeks will have been in for a bumpy ride. During the first part of 2011, commodity prices have soared (see A perfect storm brewing?). This has fuelled inflation and has caused the Bank of England to revise upwards its forecast for inflation (see Busy doing nothing see also Prospects for Inflation).

But then in the first week of May, commodity prices plumetted. On the 5 May, oil prices fell by 7.9% – their largest daily amount since January 2009. Between 28 April and 6 May silver prices fell from $48.35 per ounce to just over $33.60 per ounce – a fall of over 30%. And it was the same with many other commodities – metals, minerals, agricultural raw materials and foodstuffs.

Many financial institutions, companies and individuals speculate in commodities, hoping to make money buy buying at a low price and selling at a high price. When successful, speculators can make large percentage gains in a short period of time. But they can also lose by getting their predictions wrong. In uncertain times, speculation can be destabilising, exaggerating price rises and falls as speculators ‘jump on the bandwagon’, seeing price changes as signifying a trend. In more stable times, speculation can even out price changes as speculators buy when prices are temporarily low and sell when they are temporarily high.

Times are uncertain at present. Confidence fluctuates over the strength of the world recovery. On days of good economic news, demand for commodities rises as people believe that a growing world economy will drive up the demand for commodities and hence their prices. On days of bad economic news, the price of commodities can fall. The point is that when undertainty is great, commodity prices can fluctuates wildly.

Food prices: a question of supply and demand (updated)

The prices of grains and other foodstuffs are rising rapidly. Wheat prices rose some 40 per cent in July and have continued to rise rapidly since. In June wheat futures were trading at around 450 US cents/bushel. By early September, they were trading at around 700 US cents/bushel. Global food prices generally rose by 5% over the two months July/August. And it’s not just food. Various other commodity prices, such as copper and oil, have also increased substantially.

At the beginning of September there were three days of food riots in Mozambique in protest against the 30% rise in the price of bread. Seven people were killed and 288 were injured. On 2 September Russia announced that it was extending a ban on wheat exports for another 12 months following a disastrous harvest. In Pakistan, the floods have destroyed a fifth of the country’s crops. Drought in Australia and floods in the Canadian prairies have reduced these countries’ grain production.

In response to the higher prices and fears of food riots spreading, the United Nations has called a special meeting on 24 September to bring food exporters and importers together to consider “appropriate reactions to the current market situation”. And yet, although global cereal production is down by some 5% on last year, it is still predicted to be the third largest harvest on record.

So what is causing the price rises? Is it simply a question of the balance of supply and demand and, if so, what has caused the relevant shifts in supply and/or demand? And what role does speculation play? The following articles look at the issues and at the outlook for commodity prices over the coming months.

Clearly changes in commodity prices affect the rate of inflation. The news item (Bank of England navigates choppy waters) amongst other issues looks at the outlook for inflation and the various factors influencing it.
