How to create a fairer forex market
The Conversation

“If you ain’t cheating, you ain’t trying” were the words of one trader working in the foreign exchange market. They belie an attitude that was widespread among traders in this market between 2009 and 2013. Cheating was simply a normal part of a trader’s day job. In fact, not cheating would be to shirk your duties.

Widespread cheating in the foreign exchange market has turned out to be very costly indeed. In the past six months, six large banks around the world have paid out $US10 billion in fines over the manipulation of the global foreign exchange market. There have also been fines levied against banks for manipulating other over-the-counter markets such as LIBOR, the ISDAfix and the gold market.

In addition there have been fines for other bad behaviour by banks like money laundering, their role in the sub-prime mortgage crisis, violating sanctions, manipulation of the electricity market, assisting tax evasion, and mis-selling payment protection insurance. This brings the total amount of fines which banks have paid since 2008 to over $US160 billion. To put this in context, this is more than what the UK government spent on education last year.

Cleaning up their act

As the cost of misbehaviour mounts, banks are under increasing pressure to clean up their act. Despite widespread public cynicism, much has already changed within the banking sector. Banks have beefed up their risk function and increased oversight of traders.

They have also changed the tone from the top. Senior managers of the boom years who promoted a hard-driving, risk-taking culture have largely been replaced by bankers who talk more about ethics, careful risk management and serving the customer. A new legal regime has been put in place to hold senior bank employees personally responsible for wrong-doings on their watch.

Banks are required to hold more equity on their balance sheets. There have been new laws which change the way bankers are paid, to emphasise long-term performance rather than short-term risk taking. Riskier trading and investment banking operations are being ringfenced from their more staid retail banks.

Problems with the market

All these changes might be making bankers safer, but will they do anything to make the markets which they operate within any less likely to reward bad behaviour? We usually assume a market like foreign exchange emerges from millions of individual decisions. Changing this might sound impossible.

But each of these decisions are made within a particular set of constraints. These constraints are the product of deliberate policy design choices. Changing behaviour in a market like foreign exchange involves looking carefully at the design of the market and asking whether this actually does the job it is supposed to do.

As it currently stands, the foreign exchange market seems to be designed to create opportunities for bad behaviour:

It is huge: $US5.3 trillion passes through the market every single day.

It is extremely opaque. Because it is an over-the-counter market, there is no centralised point where trades are cleared and recorded. What this means is that unlike the sharemarket, there is no single point of information about how much has been traded and at what price.

It is extremely concentrated. Although millions of people participate in the foreign exchange market every day, only four banks control over half the market. This effectively means that over $US2.6 trillionis traded by a couple of hundred people working for these big institutions.

It is almost entirely self-regulated. Although there are many laws which apply in other financial markets such as shares, regulation is almost entirely absent in currency trading. The main body which oversees the operation of the market is a panel appointed by the Bank of England whose membership is comprised of mainly currency traders.

It is difficult to expect that a huge and opaque market, controlled by a small handful of players who self-regulate will produce angelic behaviour.

Changing the design

To change behaviour within this market, some of these design choices need to be revisited. If policymakers wanted to reduce the size of this gigantic market, they could place a small transaction tax on each currency trade. This would probably have the effect of driving out much of the speculative trading in currency (and related financial instruments) which makes up the great majority of the market.

To make the market more transparent, banks which run large trading platforms could be required to share information about the volume of trades as well as the price of trades they are making. This would reduce the information asymmetries between the large banks (who know what is going on) and others (who do not).

To make the market less concentrated, a centralised exchange similar to the share market could be established for currencies. This would quickly erode the advantages which large banks trading currency have from their currency trading platforms.

To make the market more stringently regulated, then it is possible to replace weak self-regulation by insiders with more developed regulation by an independent body. This would mean there are clear boundaries between poachers and game-keepers.

In the UK, the Bank of England is reflecting on some of these design choices. With its 'fair and effective markets review', it is looking at the design of FICC (Fixed Income, Currency and Commodities) markets. So far this has been mostly engaged with by financial firms and their representatives, and some policy options have already been pushed off the table. For instance, there is little prospect of a centralised currency exchange or a Tobin tax on currency trading.

Many important choices remain to be made, however. One big question is whether these crucial market design decisions will be ones that are made by market insiders and technocrats, or whether they will involve some degree of genuine democratic deliberation. This is an important question to ask. As my colleague Emilio Marti has recently argued, making decisions about the design of our financial markets in a more democratic way will lead to more just outcomes. Keeping the decisions on how the biggest market in the world is designed in the hands of a small number of regulators, economists and currency traders may not lead to a fairer market.
