Is the time right for a Tobin tax?

On several occasions in the past on this site we’ve examined proposals for a Tobin tax: see, for example: A ‘Robin Hood’ tax (Feb 2010), Tobin or not Tobin: the tax proposal that keeps reappearing (Dec 2009) and A Tobin tax – to be or not to be? (Aug 2009). A Tobin tax is a tax on trading in financial products, sometimes known as a ‘financial transactions tax’ (FTT). It could also be levied on trading in foreign currencies. It is considered in Economics (7th ed) (section 26.3) and Economics for Business (5th ed) (section 32.4).

The tax would be levied at a very low rate: somewhere between 0.01% and 0.5% and would be too small to affect trading in shares or other financial products for purposes of long-term investment. It would, however, dampen speculative trades that take advantage of tiny potential gains from very short-term price movements. Such trades account for huge financial flows between financial institutions around the world and tend to make markets more volatile. The short-term dealers are known as high-frequency traders (HFTs) and their activities now account for the majority of trading on exchanges. Most of these trades are by computers programmed to seek out minute gains and respond in milliseconds. And whilst they add to short-term liquidity for much of the time, this liquidity can suddenly dry up if HFTs become pessimistic.

The President of the European Commission, José Manuel Barroso, has announced that the Commission has adopted the idea of a financial transactions tax with the backing of Germany, France and other eurozone countries. This Tobin tax could be in operation by 2014. According to the Commission, it could raise some €57bn a year. Unlike earlier proposals for a Tobin tax (sometimes called the ‘Robin Hood tax’), the money raised would probably be used to reduce EU deficits, rather than being given in aid to developing countries.

The UK government has been highly critical of the proposal, arguing that, unless adopted world-wide, it would divert trade away from the City of London.

The following articles consider how such a tax would work and its potential advantages and disadvantages.

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.

Down the big dipper again

Friday 5 August 2011 saw the end of a very bad fortnight for stock markets around the world. In Japan the Nikkei 225 had fallen by 8.2%, in the USA the Dow Jones had fallen by 9.8%, in the UK the FTSE 100 was down 11.6% and in Germany the Dax was down 14.9%. In the first five days of August alone, £148 billion had been wiped off the value of the shares of the FTSE 100 companies and $2.5 trillion off the value of shares worldwide.

But why had this happened and what are likely to be the consequences?

The falls have been caused by the growing concerns of investors about the health of the global economy and the global financial system. There are worries that the European leaders at their summit on 21 July did not do enough to prevent the default of large countries such as Spain and Italy. There are concerns that the US political system, following the squabbling in Congress over raising the sovereign debt ceiling for the country, may not be up to dealing with the country’s huge debts. Indeed, the rating agency, Standard & Poor’s, downgraded the USA’s credit rating from AAA to AA+. This is the first time that the USA has not had top rating.

Then there are worries about the general slowing down of the world economy and how this will compound the problem of sovereign debt as it hits tax revenues and makes it harder to reduce social security payments. Underlying all this is the fear that the problem of indebtedness that contributed to the banking crisis of 2007/8 has not gone away; it has simply been transferred from banks to governments. As Robert Peston states in his article, linked to below:

The overall volume of indebtedness in the economy is therefore still with us – although it has been shuffled from financial sector to public sector.

And if you took the view four years ago that the quantum of debt in the system was unsustainably large, then you would argue that by propping up the banks, the day of reckoning was being postponed, not cancelled.

… just like the awakening in 2007 to the idea that many of the housing loans and associated financial products were worthless, so there is a growing fear that a number of financially overstretched governments, especially in the eurozone, will not be able to repay their debts in full.

Which brings us to the consequences. Key to the answer is confidence. If governments can reassure markets over the coming days and weeks that they have credible policies to support highly indebted countries in the short term and to sustain demand in the global economy (e.g. through further quantitative easing in the USA (QE3)); and if they can also reassure markets that they have tough and credible policies to reduce their debts over the longer term, then confidence may return. But it will not be an easy task to get the balance right between sustaining recovery in the short term and fiscal retrenchment over the long term. Meanwhile consumers are likely to become even more cautious about spending – hardly the recipe for recovery.

Rescuing Greece? Rescuing the euro?

With a mounting crisis in the eurozone, heads of government met in an emergency meeting in Brussels on 21 July.

The task was a massive one: how to tackle Greece’s growing debt crisis and stave off default; how to protect other highly indebted countries which have already had to seek emergency bailouts, namely Ireland and Portugal, from falling market confidence and thus rising interest rates, thereby making their debts harder to service; how to prevent speculative pressures extending like a contagion to other highly indebted countries, such as Spain and Italy; how to prevent speculation against the euro and even to prevent its break-up; how to reduce the size of budget deficits at a time of low growth without jeopardising that growth. A problem is that Greece has already adopted the required austerity measures for it to receive a second bailout from the EU agreed at the end of June, and yet its debt burden is likely to rise as growth remains negative.

Eurozone leaders recognised that the stakes were high. Failure could see contagion spread, interest rates soar and perhaps one or more countries leaving the euro. No agreement was not an option. As it turned out, the agreement was more comprehensive than most commentators had expected. Markets reacted positively. Stock markets in Europe and around the world rose and the euro strengthened.

So what was the agreement? Has it solved the Greek and eurozone crises? Will it prevent contagion? Or has it merely put the problem on hold for the time being? Will more fundamental measures have to be put in place, such as much fuller fiscal union, if the eurozone is to function as an effective single currency area? The following is a selection of the hundreds of articles worldwide that have reported on the summit and the agreement.

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.
