First, the data confirmed earlier reports that average daily forex volume had surged to a record level in 2010: “Global foreign exchange market turnover was 20% higher in April 2010 than in April 2007, with average daily turnover of .0 trillion compared to .3 trillion. The increase was driven by the 48% growth in turnover of spot transactions, which represent 37% of foreign exchange market turnover. The increase in turnover of other foreign exchange instruments [consisting mainly of swaps and accounting for the majority of forex trading activity] was more modest at 7%.” In addition, for the first time, investors and financial institutions accounted for a larger share of turnover than banks, whose trading activity has remained roughly unchanged since 2004.

The composition of the turnover actually didn’t change from 2007, interrupting a shift which had been taking place over the previous 10 years. Specifically, the share of overall turnover accounted for by the so-called major currencies actually increased in 2010, from 172% to 175%. [Since there are two currencies in every transaction, total volume sums to 200%]. Growth in the G4 currencies (Dollar, Euro, Pound, Yen) was more modest, however, increasing from 154% to 155%. This reversal is probably attributable to the credit crisis, which drove (and in fact, continues to drive) investors out of emerging market currencies and back into safe haven currencies, namely the Dollar, Yen, and Pound. However, this theory is belied by the significant increase in Euro trading activity, which certainly hasn’t benefited from the recent trend towards risk aversion.

While emerging currencies as a group accounted for a smaller share of overall activity, certain individual currencies managed to increase their respective shares. The Singapore Dollar, Korean Won, New Turkish Lira, and Brazilian Real all fit into this category. Still other currencies, such as the Indonesian Rupiah and Malaysian Ringgit, also managed impressive gains but account for such a small share of volume as to be insignificant when looking at the overall the picture. Those who were expecting even bigger growth should remember that it’s ultimately a numbers game: the amount of Ringgit it outstanding is dwarfed by the number of Dollars, so any gains that the Ringgit can eke out are impressive. In addition, when you consider that the overall forex pie is also increasing, the nominal increase in volume for these small currencies was actually quite large.

The ongoing search for yield in all corners of the financial markets is likely to bring some of the more obscure currencies into the fold. “In June, I began getting questions about Uruguay, Vietnam and others,” said Win Thin, senior currency strategist at Brown Brothers Harriman in New York…investors often asked Mr. Thin questions about less-familiar currencies such as the Ukrainian hryvnia and Romanian leu.” In the same article, however, Mr. Thin cautioned that interest in such currencies is still probably lower than in 2007-2008, for a good reason. “It’s not like the Group of 10, or even the more liquid emerging market currencies where, if you decide you’ve made a mistake, you can get out.”

Due to the lack of liquidity and <a href=”http://fxtrade.oanda.com/forex_trading/why_trade_with_oanda/spreads/recent_oanda_spreads#exotics”>higher spreads, these obscure currencies aren’t really suitable for trading. Of course there will be a handful of institutional and even retail investors that want to make long-term bets on these currencies. They tend to be more aware of the risk and less sensitive to the higher cost and lower convenience. The overwhelming majority of traders, however, churn their portfolios daily, if not hundreds of times per day. A 10pip spread on the USD/MXN (Dollar/Mexican Peso) would be considered too high, let alone a 50 pip spread on any transaction involving the Ukrainian hryvnia.

In short, the majors will account for the majority of trading volume for the foreseeable future, regardless of what happens to the Euro. At the same time, that won’t prevent a handful of selected emerging currencies, such as the Chinese Yuan, Indian Rupee, Brazilian Real, and Russian Ruble from increasing their share. As liquidity rises and spreads decline, volume will increase, and their rising importance will become self-fulfilling.

It can foremost be attributed to a disconnect between Chinese words and Chinese action. While The People’s Bank of China (PBOC) purportedly supports a stronger, flexible Yuan (”Adopting a more flexible exchange-rate regime serves China’s long-term interests as the benefits…far exceed the cost in reorganising industries and removing outdated capacities.”), in practice, it has prevented the currency from budging. On numerous occasions since supposedly allowing the RMB to appreciate, it has intervened in the forex markets through various shadow dealers to prevent this very outcome.

In fact, China has increased its purchases of South Korean and Japanese sovereign debt, ostensibly as part of its diversification strategy, but more likely to put upward pressure on those currencies. “Data from Japan’s Ministry of Finance show that China bought a net 1.73 trillion yen (.3 billion) of Japanese government bonds in the first half of this year, compared with a net sale of 5.9 billion yen ( million) a year earlier. That strong demand has been a key factor strengthening the yen in recent weeks.” This could have broad implications, since in the last quarter, China accumulated Billion in new forex reserves, and seems intent on further diversifying out of US Dollar-denominated assets.

China’s general obstinacy towards in dealing with the Yuan is baffling to market observers, especially given the trade surplus of nearly Billion in June, its largest since January of 2009. In fact, China can be seen moving backwards. It recently inaugurated a pilot program that will allow exporters to hold offshore accounts of foreign currency, which might be expected to relieve some of the upward pressure on both the Yuan and on China’s foreign exchange reserves: “If you don’t force firms to surrender their foreign-exchange proceeds, then they won’t be exchanged for renminbi, which is a source of appreciation pressure.” In this way, China can both limit speculative capital inflows (even by domestic investors) and inflation.

Foreign governments, led by the US, are still threatening action. Senators and Congressmen continue to harp on the issue (it is election season, after all), and are still threatening to slap a tariff on all Chinese imports. However, their efforts are being undermined by both the Department of Treasury (which refuses to label China a “currency manipulator”) and the Department of Commerce, which recently determined that the application of a broad-based tariff on all Chinese imports would violate its mandate.

I have always been cynical about China’s forex policy, on the basis that it is self-interested and disingenuous, and I think the fact that it remains pegged to the USD confirms that sentiment. In the end, China won’t bow to international pressure. It will only allow the Yuan to appreciate after it has determined that its economy won’t be negatively impacted, and even then, the pace will be glacial.
