Minor pairs: no USD but still liquid

When beginners first explore the foreign exchange market, they often assume that liquidity is synonymous with the US dollar. They gravitate toward the majors—EUR/USD, GBP/USD, USD/JPY—because these pairs dominate trading volume and offer tight spreads. But this assumption overlooks an entire category of currency pairs that are both highly liquid and completely free of the US dollar: the minor pairs, also known as cross pairs. Understanding how these pairs function, why they exist, and how to trade them effectively separates casual retail traders from those who truly understand currency market structure.

A minor pair, in the strictest sense, is any currency pair that does not include the US dollar but involves at least one major currency from a strong, developed economy. The most common examples include EUR/GBP, EUR/JPY, GBP/JPY, and EUR/CHF. These pairs are not “minor” in the sense of being illiquid or obscure. Rather, they are called minors because they cross two major currencies directly, bypassing the USD entirely. This designation is a matter of categorization, not quality. In terms of daily turnover, EUR/JPY alone trades billions of dollars worth of volume every day, often rivaling some of the less active major pairs.

The liquidity of minor pairs comes from two interconnected sources. First, the underlying economies—the Eurozone, Japan, the United Kingdom, Switzerland, and to some extent Australia and New Zealand—are deeply integrated into global trade and finance. Japanese exporters routinely hedge yen exposure against the euro, British asset managers swap sterling for yen when diversifying into Tokyo equities, and European banks trade the franc for balance sheet adjustments. These institutional flows create constant, deep order books regardless of whether the US dollar is involved. Second, the interbank market in London, the world’s largest FX hub, actively quotes and trades these crosses as standard products, meaning spreads remain competitive even for retail traders.

Why would a trader choose a minor pair over a major pair? The answer lies in opportunity cost and correlation. When the US dollar is undergoing a strong directional move—say, a broad rally based on Federal Reserve rate hikes—most dollar pairs become highly correlated. EUR/USD, GBP/USD, and USD/JPY all move in predictable patterns relative to the dollar, but those patterns can become one-dimensional. Minor pairs, by virtue of excluding the dollar, isolate the relative strength or weakness between two non-dollar currencies. For example, if the euro is weakening due to political uncertainty but the yen is simultaneously weakening due to ultra-loose Bank of Japan policy, EUR/JPY may move in a way that is entirely independent of what the dollar is doing. This allows a trader to profit from specific macroeconomic divergences without being whipsawed by dollar noise.

Advanced traders also exploit minor pairs for carry trade strategies. Because these pairs involve interest rate differentials between economies such as Australia and Japan, the yields can be more extreme than those available in dollar-based pairs. A trader holding a long position in a high-yielding minor pair can collect daily swap interest that compounds over time. The liquidity of these pairs ensures that entering and exiting such positions does not come with excessive slippage, which would otherwise erode the carry advantage.

However, trading minor pairs demands a higher level of fundamental awareness. Since there is no USD as an intermediary, a trader must analyze the monetary policy, economic data, and geopolitical developments of two foreign economies simultaneously. A sudden move in the Bank of England’s interest rate decision can spike GBP/JPY by hundreds of pips, but only if the trader understands both sterling’s reaction and the yen’s concurrent behavior. This is not a weakness but a feature. For the moderately active investor who already monitors multiple global markets, minor pairs offer a purer expression of specific economic narratives.

Spreads on minor pairs are typically wider than on EUR/USD but narrower than on any exotic pair involving a dollar. A seasoned trader will accept this as a small cost for the benefit of diversification. The key is to know when liquidity is at its peak. Minor pairs involving European currencies are most liquid during the London and New York overlaps. Asia-based crosses like EUR/JPY and GBP/JPY also see significant volume during the Tokyo session, making them attractive for around-the-clock trading.

For the serious trader building a portfolio, minor pairs are not an afterthought. They are a tool for separating signal from noise, for capturing carry returns, and for trading currency relationships without the gravitational pull of the US dollar. The investor who masters these crosses gains an edge that most retail participants never develop—a deeper command of how global capital flows truly work.
