Start with both sides of the currency pair
Forex fundamental analysis examines the economic and policy conditions behind a currency. For a pair such as AUD/CHF, analyse Australia and Switzerland together: AUD is the base currency and CHF is the quote currency. A rise in AUD/CHF means one Australian dollar buys more Swiss francs. A positive Australian release alone does not establish which currency will outperform.
Use a repeatable sequence: identify each central bank’s benchmark, compare inflation trends, check labour-market conditions, then compare real economic growth. Record the observation period and publication date for every figure. Distinguish what the data shows from what you think policymakers or markets might do next.
1. Compare policy rates and their definitions
An interest-rate differential is the selected base-currency policy rate minus the selected quote-currency policy rate. In a hypothetical example, 4.00% minus 2.50% equals 1.50 percentage points, or 150 basis points. Reversing the pair reverses the sign.
The underlying benchmarks are not always identical: one bank may publish a target range while another publishes a single deposit rate or cash-rate target. Read the definition before comparing. The current differential is not your broker’s swap rate, and it does not reveal the future path of either policy rate.
2. Read inflation as a trend, with the right period
Headline CPI measures changes in a consumer price basket. A year-on-year reading compares prices with the same period a year earlier; a month-on-month reading compares adjacent months. Do not plot those two growth measures together as though they mean the same thing. Euro-area HICP also differs in coverage from national CPI measures.
For example, inflation falling from 4% to 3% means prices are rising more slowly relative to a year earlier. It does not mean the overall price level fell. A change may reflect current prices, a change in the comparison period a year earlier, or both. Keep quarterly readings quarterly and check whether a series has been discontinued or rebased.
3. Check unemployment without mixing definitions
The unemployment rate measures unemployed people as a share of the labour force under a particular statistical definition. It is not the share of the entire population without a job. Survey coverage, age groups and seasonal adjustment can differ across economies.
Compare the latest available period for each country and inspect the direction over several observations. One economy may publish monthly data while another publishes quarterly data. A falling rate can coincide with changes in labour-force participation, so it is not a complete description of labour-market strength.
4. Compare real GDP growth on the same basis
Real GDP adjusts economic output for price changes. For a cross-country growth comparison, distinguish quarter-on-quarter growth, year-on-year growth and annualised quarterly growth. A 0.5% quarterly increase is approximately 2.02% at an annualised pace: (1.005 to the fourth power minus 1) multiplied by 100. These describe the same hypothetical quarter using different conventions.
Trade90’s comparison charts label quarterly growth without annualising it. Read the source notes for revisions and changes in geographical composition. Comparing a large economy’s GDP in dollars with a small economy’s GDP in dollars answers a different question from comparing their growth rates.
5. Separate the release from the market reaction
The observation period, release date and retrieval date answer different questions. “August CPI” describes August prices; it may be released in September and downloaded later. A fresh download timestamp does not make an old observation current.
Actual-versus-consensus surprises require a separately sourced consensus estimate. Historical charts alone cannot establish whether a release beat expectations, how traders were positioned or what is priced into interest-rate markets. Do not label a currency bullish or bearish solely because one chart rose or fell.
Turn the comparison into a research note
Write a short note with four parts: the relative economic picture, the dated evidence supporting it, the next releases that could change it, and the information you still lack. For AUD/CHF, keep both the RBA and SNB policy context visible alongside both countries’ inflation, unemployment and GDP observations.
Then keep risk sizing separate from the research view. A position-size calculation needs account currency, stop distance, contract size and conversion assumptions. The calculation is only as reliable as those inputs; neither a macroeconomic view nor a stop order guarantees an execution price or a profitable outcome.
