a growing segment of this market with the advent of retail foreign exchange platforms, both in size and importance. Currently, they participate indirectly through brokers or banks. Retail brokers, while largely controlled and regulated i

n the USA by the Commodity Futures Trading Commission and National Futures Association, have in the past been subjected to periodic foreign exchange fraud.[66][67] To deal with the issue, in 2010 the

NFA required its members that deal in the Forex markets to register as such (I.e., Forex CTA instead of a CTA). Those NFA members that would traditionally be subject to minimum net capital requirements, FCMs and IBs, are subject to greater minimum net capital requirements if they deal in Forex

. A number of the foreign exchange brokers operate from the UK under Financial Services Authority regulations where foreign exchange trading using margin is part of the wider over-the-counter derivatives trading industry that includes Contract for differences and financial spread betting.

There are two main types of retail FX brokers offering the opportunity for speculative currency trading: brokers and dealers or market makers. Brokers serve as an agent of the customer in the broader FX market, by seeking the

best price in the market for a retail order and dealing on behalf of the retail customer. They charge a commission or mark-up in addition to the price obtained in the market. Dealers or market makers, by contrast, typically act as principal in the transaction versus the retail customer, and quote a price they are willing to deal at.

Non-bank foreign exchange companies[edit]

200%
There is no unified or centrally cleared market for the majority of trades, and there is very little cross-border regulation. Due to the over-the-counter (OTC) nature of currency markets, there are rather a number of interconnected marketplaces,

On the spot market, according to the 2013 Triennial Survey, the most heavily traded bilateral currency pairs were:

EURUSD: 24.1%
USDJPY: 18.3%

GBPUSD (also called cable): 8.8%
and the US currency was involved in 87.0% of transactions, followed by the euro (33.4%), the yen (23.0%), and sterling (11.8%) (see table). Volume percentages for all individual currencies should

add up to 200%, as each transaction involves two currencies.

Trading in the euro has grown considerably since the currency's creation in January 1999, and how long the foreign exchange market will remain dollar-centered is open to debate. Until recently, trading the euro versus a

non-European currency ZZZ would have usually involved two trades: EURUSD and USDZZZ. The exception to this is EURJPY, which is an established traded currency pair in the interbank spot market.

As the dollar's value has eroded during 2008, interest in using the euro as reference currency for prices in commodities (such as oil), as well as a larger component of foreign reserves by banks, has increased dramatically[citation needed]. Transactions in the currencies of commodity-producing countries, such as AUD, NZD, CAD, have also increased.[citation needed]

Determinants of exchange rates[edit]
Main article: Exchange rate
The following theories explain the fluctuations in exchange rates in a floating exchange rate regime (In a fixed exchange rate regime,

rates are decided by its government):

International parity conditions: Relative Purchasing Power Parity, interest rate parity,

Domestic Fisher effect, International Fisher effect. Though to some extent the above theories provide logical explanation for the fluctuations in exchange rates, yet these theories falter as they are based on challengeable assumptions
