Every currency is the financial share of a country. To know if a currency is cheap or expensive, you need to understand the country behind it. What does it produce? What does it export? Is it earning more than it spends?
The Macro Anatomy of the G8 Currencies
• United States (USD): A consumer and services economy. The dollar is the global reserve currency. The US can run trade deficits others cannot. • Eurozone (EUR): Germany and the Netherlands drive exports. Italy and Spain drive tourism and services. The euro is sensitive to energy costs and global trade. • Japan (JPY): A major exporter of cars and electronics. Japan has the world's largest net foreign assets. It has an ageing population and has struggled with low inflation for decades. • United Kingdom (GBP): Dominated by financial services. The UK imports most of its food and energy. It runs a persistent trade deficit. • Australia (AUD) & New Zealand (NZD): Major commodity and food exporters. Australia's economy closely tracks Chinese demand for iron ore and coal. • Canada (CAD): A large energy exporter. Oil and gas prices directly affect CAD. Over 75% of Canadian exports go to the US. • Switzerland (CHF): Known for pharmaceuticals, precision engineering, and private banking. It runs a large trade surplus. The franc is a traditional safe haven.
Commodity Currencies vs Manufacturing Exporters
Commodity currencies move with raw material prices. When oil rises, the Canadian dollar tends to rise. When iron ore rises, the Australian dollar follows. These links are not perfect, but they are strong enough to trade.
Manufacturing exporters like Germany and Japan benefit from strong global demand for their goods. When world trade slows, these economies feel it first.
Current Account Deficits vs Surpluses
A current account surplus means a country earns more from exports than it spends on imports. This creates constant demand for that country's currency. Switzerland, Germany, and Japan all run surpluses. Their currencies have a natural structural bid.
A current account deficit means the opposite. The country buys more than it sells. It needs foreign investors to fund the gap. If those investors pull back, the currency falls. The UK and US both run deficits, but the US dollar is protected by its reserve currency status.
Sovereign Debt-to-GDP & Fiscal Health
High government debt relative to GDP is a long-term drag on a currency. It signals that the government may need to print money or default. Japan carries the highest debt-to-GDP ratio among major economies, above 250%. Yet the yen remains a safe haven because Japan's debt is mostly held domestically.
For most countries, a rising debt-to-GDP ratio is a bearish fundamental signal over multi-year timeframes. It does not move currencies day to day, but it matters for long-term positioning.
Building Your Monthly Currency Scorecard
Professional macro traders score each currency every month. They do not rely on feelings. They rate each currency on four key pillars and pair the strongest against the weakest.
Pillar 1: Central Bank Policy Bias (+2 Hawkish, 0 Neutral, -2 Dovish) Pillar 2: Economic Growth Momentum (+1 Accelerating, 0 Stable, -1 Slowing) Pillar 3: External Trade Balance (+1 Surplus, -1 Deficit) Pillar 4: Risk Sentiment Alignment (+1 Risk-On Beneficiary, -1 Risk-Off Vulnerable) Trading Rule: Pair the highest-scoring currency against the lowest-scoring one. This gives you the path of least fundamental resistance. Example: Long AUD/JPY when AUD scores +5 and JPY scores -4.
