Major currency pairs are the most traded FX pairs, typically built around the U.S. dollar, and they move mainly on interest-rate expectations, economic data, risk sentiment, trade flows, and commodity prices. The core seven majors are EUR/USD, USD/JPY, GBP/USD, USD/CHF, AUD/USD, USD/CAD, and NZD/USD.¹^{, 2}^{, 3}

Major pairs

These are the pairs traders watch most because they combine large economies and deep liquidity. EUR/USD is the most actively traded major, while the others each reflect a different mix of policy, growth, and global risk appetite.²^{, 3}^{, 4}

Pair	Main theme
EUR/USD	Fed vs ECB policy gap, growth in the U.S. and euro area ⁵
USD/JPY	U.S.-Japan yield differentials and safe-haven flows ⁵
GBP/USD	UK growth, inflation, and BoE expectations ⁶^{, 5}
USD/CHF	Risk aversion and safe-haven demand for CHF ⁵
AUD/USD	Global growth, China demand, and commodity prices ⁵
USD/CAD	Oil prices and Canada-U.S. economic balance ⁵
NZD/USD	Risk sentiment, rates, and commodity exposure ⁴^{, 5}

What moves them

Exchange rates move because demand for one currency changes relative to the other, so the pair price adjusts continuously. Higher interest rates often support a currency because they can attract capital, while inflation, GDP, and employment data shape expectations for future policy moves. Trade surpluses can lift a currency through stronger external demand, and market expectations matter because surprise central-bank actions often trigger the biggest moves. In stressed markets, investors often rotate toward safe havens like USD, JPY, and CHF, which can move those pairs quickly.⁵^{, 6}^{, 7}^{, 8}

How the mechanism works

Pair-by-pair intuition

EUR/USD often trades like a contest between the Federal Reserve and the European Central Bank. USD/JPY is especially sensitive to U.S.-Japan rate gaps and whether markets are seeking safety or risk. AUD/USD and USD/CAD are more tied to commodity cycles, especially metals and oil. GBP/USD tends to react sharply to UK inflation, growth, and Bank of England guidance.⁶^{, 5}

Practical takeaway

A useful way to read any major pair is to ask: which central bank is likely to be more hawkish, which economy is growing faster, and is the market in risk-on or risk-off mode. For commodity-linked pairs, also check oil, iron ore, and gold; for safe-haven pairs, watch geopolitical stress and yield spreads.⁷^{, 5}^{, 6}
