USD/JPY
A USD/JPY framework centred on relative yields, Bank of Japan policy, US data, carry conditions and the exceptional risk of official intervention.
Three branches. No forecast.
Fill these branches with dated evidence before viewing the outcome. If none completes, the result is no trade.
Dollar-yen carry impulse persists
The relative-yield and policy backdrop supports the dollar while price accepts above declared structure without disorderly acceleration.
Evidence required: A dated, observable widening or persistence of the selected yield differential; Price acceptance beyond the boundary using the frozen rule; An explicit intervention-risk check and smaller risk where warranted.
Invalidation: The selected yield relationship turns, price loses accepted structure, or official action changes execution conditions beyond the tested model.
Policy and intervention risks offset
Yield support and yen-policy risk conflict, leaving price inside a wide range or prone to false breaks. Capital preservation takes priority.
Evidence required: Conflicting policy evidence; Repeated rejection outside the working range; No stable invalidation that survives plausible slippage.
Invalidation: A sustained policy repricing and accepted break align. A single rumour-driven candle does not qualify.
Yen recovery is confirmed
The US-Japan differential narrows, risk deleveraging accelerates or credible Japanese policy action aligns with price acceptance below support.
Evidence required: Observable confirmation beyond intervention speculation; Lower acceptance or failed recovery under the declared rule; Position sizing that recognises gap and slippage risk.
Invalidation: The pair regains the boundary while relative yields and policy evidence return to the prior state.
Know what the chart actually measures.
USD/JPY rises when one US dollar buys more yen. Because the yen is the quote currency, a higher chart can represent dollar strength, yen weakness or both.
Rate differentials and hedging costs matter, but the relationship is not mechanical. Risk aversion, repatriation, options and intervention risk can dominate for periods.
Official comments and suspected intervention can produce abrupt moves and poor fills. A stop is an instruction, not a guaranteed price.
Facts before interpretation.
Give every observation a source, timestamp and job. A narrative is not independent confirmation when each item was inferred from the same price move.
Track the maturity that best matches the research horizon and state whether nominal or real yields are being used. Avoid changing the chosen measure after seeing the result.
Use policy statements, outlook reports, inflation and wage evidence. Separate a policy decision from press speculation about one.
Monitor official Ministry of Finance communications and the speed and disorderliness of movement. Do not claim intervention from a candle shape alone.
Compare the pair with volatility and broader risk behaviour. A carry narrative can fail quickly when funding positions are reduced.
Events change the distribution, not the rule.
Check the official calendar before analysis and again before execution. Record the expected release time and timezone; actual releases, revisions and press conferences can arrive on different schedules.
- Bank of Japan and Federal Reserve decisions, outlooks and minutes
- Japanese inflation, wages and negotiated-pay evidence
- US inflation, labour-market and activity data
- Changes in US and Japanese government-bond yields
- Official Japanese currency comments, confirmed intervention data and risk shocks
A valid conclusion can be “stand aside.”
Scenario invalidation and position risk are different. Invalidation says the idea is no longer supported; position size controls what that error may cost. Do not move one to repair the other.
- Price is moving rapidly on unverified intervention rumours.
- The stop distance is too small to accommodate observed event volatility and cannot be resized safely.
- BoJ or Fed event risk is imminent and the strategy excludes policy announcements.
- The thesis depends on a yield series or chart timestamp that has not been recorded.
Timestamp the work before the next candle.
This is an evergreen research framework, not a current market call. It is reviewed when market mechanics, benchmark construction or the source set changes, and at least quarterly while the hub is active. Any dated study must state its data cutoff, chart source and timezone separately.
Review the record. Never rewrite it.
The archive is intentionally empty until a dated, source-labelled study is frozen. Future entries should move through draft, frozen, observed and reviewed states. A correction appends a note; it does not replace the original thesis.
- Save the exact yield series, maturity and observation timestamp used.
- Label intervention as confirmed, reported or inferred; never merge the three.
- Stress the planned fill with gap and slippage assumptions before scoring execution.
- Compare the scenario with yen crosses to test whether the move was dollar-led or yen-led.
Model the ways a correct idea can still lose.
- Official intervention and abrupt liquidity gaps
- Carry-trade liquidation during volatility shocks
- Policy communication released outside expected Western market hours
- Different pip-value conventions and large nominal quote levels
