What is trading?
ADVANCED: COURSE 1 | LESSON 1
Macro frameworks: rate differentials, carry, risk-on/risk-off
Learning objectives
Explain how interest-rate differentials and rate expectations drive currency direction and forward pricing
Compute the approximate carry on a real position and identify when a carry trade is attractive or dangerous
Classify the current market regime as risk-on or risk-off and map which currencies typically benefit from each
Rates set the board; everything else moves the pieces
By the Professional level you already know that "the Fed hiked, so the dollar went up" is too crude to trade. Currencies do not respond to interest rates; they respond to changes in expected interest rates relative to another currency. If the market has priced three Fed cuts and the Fed delivers three cuts, the dollar may not move at all — the information was already in the price. If the Fed delivers two, that is a hawkish surprise and the dollar typically rallies even though rates fell.
The practical objects to watch are not headline policy rates but the instruments that encode expectations: short-term interest-rate futures (Fed funds futures, SONIA and Euribor equivalents) and 2-year government bond yields. The 2-year yield differential between two countries is one of the cleanest macro anchors for a currency pair, because two years is roughly the horizon over which one policy cycle plays out. When the US–Germany 2-year spread widens in favour of the US, EUR/USD tends to fall; when it compresses, EUR/USD tends to rise. The correlation is regime-dependent — it strengthens when monetary policy is the market's dominant story and weakens when something else (a banking scare, an energy shock, an election) takes over. Part of the professional's job each week is deciding which driver is currently in charge, not assuming the same one always is.
Rate differentials in your P&L: swap points and forwards
The rate differential is not just a directional story — it is cash that flows through your account every day you hold a position, via the swap (rollover).
Covered interest parity ties it together: the forward price of a currency pair differs from spot by (approximately) the interest differential over the forward period. A currency with higher interest rates trades at a forward discount — the forward price is below spot — because otherwise you could borrow the low-yielder, buy the high-yielder, hedge with a forward and lock in a riskless profit. Your overnight swap is essentially a one-day slice of that forward adjustment, plus the broker's markup.
Worked example. Suppose the Mexican overnight rate is 8.0% and the Japanese rate is 0.5%. You go long MXN/JPY — long the high-yielder, funded by the low-yielder. The gross annualised carry is roughly the differential, 7.5%, before broker markup. On a position with a notional of $100,000, that is about $7,500 a year, or roughly $20–21 per day — reduced in practice by the broker's swap markup, so expect meaningfully less than the theoretical figure. Check the actual swap rates in your MT4/MT5 contract specifications rather than assuming the theoretical number; the markup varies by pair and can turn a small theoretical positive into an actual negative.
Two consequences matter. First, holding against the differential (short MXN/JPY here) means paying that carry every night, so a swing short needs to earn its cost before it earns you anything. Second, carry compounds with time: a 3-week hold at −$25/night is −$525 of headwind on a trade you may have sized to risk $1,000.
Carry trades: picking up coins, watching for the steamroller
The carry trade — long high-yielder, short low-yielder, earn the differential — has a well-documented return profile: long periods of small steady gains punctuated by violent losses. The reason is mechanical. Carry positions crowd into the same trades (long AUD/JPY, long MXN/JPY, long EM versus JPY and CHF). When a shock hits, everyone exits at once, and the funding currencies (JPY, CHF) rally hard precisely when the high-yielders are falling. The distribution is negatively skewed: you earn 20 pips a week for months, then give back 800 pips in three days. August 2024's yen-carry unwind — triggered by a small Bank of Japan hike — wiped out months of carry income across yen crosses in under a week, a live demonstration that the funding side, not the earning side, usually detonates the trade.
A professional treats carry as an input, not a system. Sensible uses: prefer swing longs in pairs where carry is a tailwind; demand a wider expected move when trading against carry; watch carry-basket behaviour (all yen crosses moving together) as a regime signal. The danger signs for carry unwinds are rising volatility (carry is implicitly short volatility), tightening by the funding central bank, and stretched positioning data (e.g. CFTC Commitments of Traders showing extreme yen shorts).
Risk-on, risk-off: the regime overlay
Cross-asset sentiment sorts currencies into rough behavioural groups:
- Funding / safe-haven: JPY, CHF, and usually USD. They strengthen in risk-off as carry unwinds and capital seeks depth and safety.
- High-beta / pro-cyclical: AUD, NZD, CAD, NOK, most EM. They strengthen in risk-on, alongside equities and industrial commodities.
- In between: EUR and GBP, whose risk behaviour shifts with the story of the moment.
The dollar is the awkward one: it is both the world's funding currency and its safe haven. In a garden-variety equity selloff, USD usually rallies. In a crisis centred on the US (a US-specific fiscal or banking scare), it can fall while JPY and CHF rally — you cannot shortcut this with a rule; you have to read what the shock is about.
Regime identification is a checklist, not a feeling: equity index futures direction, VIX level and change, 10-year yields (falling yields + falling equities = classic risk-off), gold, and the JPY crosses themselves. When four of five point the same way, trade with the regime — fade signals that fight it. When they conflict, the regime is transitional and position sizes should be smaller.
From framework to trade
A macro framework does not give you entries; it gives you a bias and a filter. The workflow this course builds toward: (1) establish the rate-expectation direction for each major currency from short-rate pricing and central-bank communication; (2) note where carry helps or hurts; (3) classify the risk regime; (4) only then go to the charts to time entries in the direction the macro board favours. A technically perfect setup against a hawkish-surprise repricing is a low-quality trade; an average setup with rates, carry and regime all pushing the same way is often the better bet. Lesson A1.2 adds the intermarket linkages that tell you when the board is turning.
Key takeaways
Currencies price changes in expected rates, not rate levels — watch 2-year yield differentials and short-rate futures, and judge surprises against what was already priced
Swap/rollover is a daily slice of the interest differential (minus broker markup); holding against a large differential is a measurable, compounding cost
Carry trades have negatively skewed returns: steady small gains, occasional violent unwinds that hit exactly when volatility spikes
Risk-on favours high-beta currencies (AUD, NZD, EM); risk-off favours JPY, CHF and usually USD — but the USD's role depends on where the shock originates
Use macro as bias and filter, sized to conviction — never as a standalone entry signal
