The Foreign Exchange Market

For nearly three decades after the Second World War, the world's major currencies did not float against one another. Under the Bretton Woods system, established in 1944, currencies were pegged to the U.S. dollar, and the dollar itself was convertible into gold at a fixed rate. Exchange rates moved only when governments formally renegotiated their pegs — a slow, deliberate, and rare event.

That system ended on August 15, 1971, when the United States suspended the dollar's convertibility into gold, an event now referred to as the Nixon Shock. An attempt to preserve fixed rates under the Smithsonian Agreement later that year did not hold, and by March 1973 the major economies had abandoned fixed exchange rates altogether. The Jamaica Accords of 1976 formally recognized floating exchange rates as the new international standard — the system that has remained in place ever since.

A floating currency has no official peg. Its value is set continuously by the relative supply and demand for it against every other currency, updated in real time as banks, corporations, governments, and traders transact around the world. There is no single exchange where this happens. Unlike equities, foreign exchange trades over the counter, through a decentralized network of banks, electronic platforms, and dealers spanning every major financial center — which is also why the market runs continuously, handing off from one session to the next from Monday morning in Sydney through Friday evening in New York.

The scale is difficult to overstate. According to the Bank for International Settlements' 2025 Triennial Survey, global foreign exchange turnover reached $9.5 trillion per day in April 2025 — making it, by a wide margin, the largest and most liquid financial market in the world.

The equity market represents ownership. A share of stock is a claim on a company's future earnings and assets, traded on a centralized exchange with defined operating hours, and priced primarily on that company's fundamentals — revenue, earnings, competitive position, and investor sentiment about its future.

Currency pairs represent something categorically different: relative value between two economies, not ownership of either. There is no earnings report for a currency. Its price is instead driven by macroeconomic forces — interest rate policy set by central banks, inflation differentials, trade balances, capital flows, and the market's collective read on a country's economic trajectory. A position in the FX market is not a bet on a company; it is a position on the relationship between two national economies.

The bond market represents debt — a loan made to a government or corporation in exchange for scheduled interest payments and the return of principal at a fixed maturity date. Bond prices move primarily with interest rate expectations and credit risk, and every bond has an endpoint.

Currency pairs have no maturity and represent no debt obligation. A position does not resolve on a fixed date the way a bond does; it exists for as long as it's held. And while interest rate differentials between countries are one of the central drivers of currency flows, the foreign exchange market remains a distinct asset class in its own right — not a derivative of the bond market, and not a substitute for it.

Proprietary Trading Firms

Proprietary trading — trading with a firm's own capital, for its own account, rather than on behalf of outside clients — is a practice as old as organized markets themselves. Investment banks have long maintained trading desks that deploy the firm's own balance sheet, distinct from the client-facing brokerage and asset-management businesses most people associate with Wall Street.

Over the past decade, a newer category of proprietary trading firm has grown around individual traders rather than institutional desks. These firms provide traders with access to firm capital — often ranging from tens of thousands to several hundred thousand dollars per account — in exchange for a share of the profits the trader generates.

The structure typically runs in two stages. In the first, a trader demonstrates the ability to operate within a defined set of risk parameters — maximum daily loss, maximum overall drawdown, minimum trading history — over an evaluation period, generally by paying a one-time evaluation fee tied to the account size being sought. Traders who meet the criteria move to a funded stage, trading the firm's capital under the same risk rules, and receive a share of the profits generated — commonly in the range of 80 to 90 percent, with the firm retaining the remainder.

Because the capital at risk in the funded stage belongs to the firm rather than to the trader personally, this model is structurally distinct both from traditional retail trading, where a trader risks only their own deposited funds, and from asset management, where a manager trades on behalf of outside investors' capital.

The appeal of the model is straightforward: it separates trading skill from personal capital. A trader with a disciplined, risk-managed approach but limited savings can access institutional-scale capital without raising outside investment or taking on debt, while a firm's exposure to any individual trader is bounded by the risk parameters built into the evaluation itself. As retail participation in systematic and discretionary trading has grown over the past decade, this capital-access model has grown alongside it, and now represents a meaningful and expanding part of how independent traders reach the market.
