Fundamental Analysis in Forex: What Moves Currencies

What is fundamental analysis in forex?

Fundamental analysis is the study of the economic forces that make one currency rise or fall against another over weeks and months: interest rates, inflation, jobs, growth, trade flows, commodity prices, risk sentiment and politics. The core idea is that money flows towards currencies offering better returns and stronger prospects. Traders use it to decide which direction to favour, then use charts to time their entries.

A currency pair is always a comparison. EUR/USD does not rise simply because Europe is doing well; it rises when Europe is doing better than the market expected relative to the United States. Keep the words “relative” and “expected” in mind and most of fundamental analysis falls into place.

Interest rates and central banks: the main driver

All else being equal, capital moves to where it earns more. Suppose Country A’s central bank rate is 4.5% and Country B’s is 1.0%. The differential is 3.5 percentage points in favour of A, and investors holding A’s currency earn more interest, which tends to support it. But markets look forward. If traders come to expect A to cut to 4.0% and B to raise to 1.5%, the expected differential shrinks to 2.5 points, and A’s currency can fall long before either bank actually moves.

So the question is never simply “who has the higher rate?” but “whose rate path is changing relative to expectations?” Our guide to the carry trade and interest rates explains how differentials also set the swap you pay or earn for holding positions overnight.

The economic data that matters

Central banks set rates in response to data, so traders watch the same data to anticipate them:

• Inflation (CPI) — the key input for most central banks. Inflation running above target pushes a bank towards higher rates, which usually supports the currency; inflation falling back towards target does the opposite.
• Employment — strong job creation and rising wages point to a hot economy and stickier inflation. The monthly US jobs report is the best-known example.
• GDP growth — faster growth attracts investment and gives the central bank room to keep rates higher. GDP is published with a long delay, so timelier releases such as business surveys and retail sales can move markets more.
• Trade balance and current account — a country that consistently sells more abroad than it buys has steady foreign demand for its currency. A persistent deficit must be funded by foreign capital, which leaves the currency more vulnerable when sentiment turns.

Commodities, risk sentiment and politics

• Commodity links — currencies of big commodity exporters tend to move with the prices of what they sell: the Australian dollar with iron ore and other metals, the Canadian dollar with crude oil, the Norwegian krone with oil and gas.
• Risk sentiment — when investors are nervous, money tends to flow into the safe havens — the US dollar, the Japanese yen and the Swiss franc — and out of higher-yielding and emerging-market currencies. When confidence returns, the flow reverses.
• Politics — elections, budget disputes, tariffs and geopolitical conflict change the outlook for growth, debt and policy. Markets dislike uncertainty, so a currency often weakens ahead of an unpredictable vote and may recover once the outcome is known.

These links are tendencies, not laws. USD/CAD can ignore oil for weeks when rate expectations dominate, and a safe haven can fall on a day of bad news if the bad news is about its own economy. Always ask which driver the market is focused on right now.

Expected versus actual: what “priced in” means

Markets trade on expectations, so prices already reflect the consensus forecast before a release. What moves the currency is the surprise. Suppose economists expect inflation of 3.2% and the figure comes in at 3.6%. That 0.4-point upside surprise makes higher rates more likely, and the currency will usually jump. Had the figure come in at 3.2%, exactly as forecast, the reaction might have been close to nothing, because that outcome was already priced in.

The same logic explains moves that seem backwards. If a 0.25-point rate rise has been fully expected for weeks, the currency may already have rallied, and it can fall on the announcement as traders take profits — “buy the rumour, sell the fact”. Always check three numbers on the economic calendar: previous, forecast and actual. Revisions to the previous figure can matter as much as the headline.

Hawkish versus dovish language

Central bankers move markets with words as much as with actions. Hawkish language signals concern about inflation and a willingness to raise rates or keep them high: phrases such as “further tightening may be needed” or “inflation remains too high”. Dovish language signals concern about weak growth or unemployment and an openness to cutting rates: “risks to growth have increased” or “there is room to ease if conditions weaken”.

What matters is the change in tone compared with last time. A bank that raises rates but hints that it is finished — a “dovish hike” — can send its currency lower. A bank that holds rates but drops a reassuring phrase from its statement can send it higher. Read the statement, compare it with the previous one and watch the press conference if there is one.

Combining fundamentals with technicals

Fundamentals tell you which way to lean; they are poor at telling you when to act. A currency can stay “too expensive” for months. A practical approach is to build a bias from fundamentals — for example, favouring a currency whose central bank is turning hawkish against one whose bank is turning dovish — and then take only the chart setups that point in that direction. Wait for a pullback to a level identified through support and resistance, define your stop and size the position as you normally would.

If the chart disagrees with your view for a long time, respect the chart: the market may be focused on a driver you have missed. Be careful around the releases themselves, when spreads widen and price can whip both ways; trading the news explains the specific risks.

A simple weekly routine

• At the weekend — open the economic calendar and note the high-impact events for the currencies you trade — rate decisions, CPI, jobs and GDP — along with their forecasts.
• For each currency — write one line: is its central bank leaning hawkish, dovish or neutral, and has that changed recently?
• Rank them — pair the strongest story against the weakest to get a directional bias for one or two pairs.
• Mark the danger times — decide in advance whether you will be flat, reduce size or hold through each major release.
• After each release — compare actual with forecast, watch the first reaction and note whether it held or reversed by the end of the day.
• At the end of the week — review what moved and why, and update your one-line notes.

Fundamental analysis can improve your odds; it does not remove risk. Forex and CFDs carry a high risk of loss, so only trade with money you can afford to lose.
