How to Hedge USD/JPY 24/7
USD/JPY runs in the opposite quote direction to EUR/USD. Learn which side hedges yen exposure and why a dollar-sized hedge needs rebalancing.
Go long USD/JPY to hedge the dollar value of yen you hold or expect to receive. Go short USD/JPY to hedge a future yen payment. You can manage either position around the clock through USD/JPY on Liquid.
USD/JPY measures yen per dollar, so its direction is reversed from EUR/USD. A rising USD/JPY means a weaker yen.
Why does hedging yen use the opposite direction to hedging euros?
At a hypothetical USD/JPY rate of 150, $1 buys ¥150. If the rate rises to 165, the yen weakens: each dollar buys more yen. If it falls to 135, the yen strengthens.
| Exposure measured in USD | Risk | Potential hedge |
|---|---|---|
| Yen cash or a yen receivable | USD/JPY rises; yen buys fewer dollars | Long USD/JPY |
| A future yen bill | USD/JPY falls; yen costs more dollars | Short USD/JPY |
| Japanese equities | Yen translation plus stock-price risk | Separate the FX and equity risks |
These directions assume you measure results in US dollars. A Japanese business measuring dollar income in yen needs a calculation based on its yen value.
How do you calculate the initial hedge size?
Start by converting the exposed yen amount into dollars:
Current USD value = yen amount ÷ USD/JPY rate.
For a dollar-settled linear perpetual, multiply that dollar value by the percentage you want to hedge to estimate initial notional.
For example, ¥1,500,000 at 150 is worth $10,000. An initial $10,000 long USD/JPY position approximately offsets small declines in that holding's dollar value as USD/JPY rises. A $5,000 position targets about half the initial sensitivity.
What does a yen hedge look like in numbers?
Assume you own ¥1,500,000, USD/JPY starts at 150, and you open a linear long with $10,000 of initial notional. This simplified example assumes the perp follows the same quoted rate and calculates PnL from its percentage change.
| USD/JPY at exit | Dollar value of yen | Long PnL | Combined value |
|---|---|---|---|
| 165, up 10% | $9,090.91 | +$1,000 | $10,090.91 |
| 150, unchanged | $10,000 | $0 | $10,000 |
| 135, down 10% | $11,111.11 | −$1,000 | $10,111.11 |
The totals differ because yen value is divided by USD/JPY, while the linear perp responds to the rate's percentage change. The hedge is a close approximation for small moves and needs review after larger ones. For yen liabilities, the signs reverse and the mismatch can leave an extra cost.
These hypothetical figures assume matching rates and an open hedge, before funding, fees, slippage, and collateral changes.
A stronger yen benefits an unhedged yen holder. The long USD/JPY hedge loses in that scenario, offsetting much of the benefit. Hedging reduces favorable currency exposure as well as unfavorable exposure.
How does USD/JPY trade on weekends?
XYZ's official FX schedule describes external USD/JPY pricing from Sunday 5 p.m. to Friday 5 p.m. Eastern Time. It uses internal pricing over the weekend and when external oracle data has a sufficient gap.
A weekend perp price may reflect expectations for the next session and differ from your bank's conversion rate. Check the spread and available depth before placing an order.
US and Japanese rate decisions and currency intervention can move USD/JPY quickly. Keep accessible margin for those moves, especially when your bank or brokerage is closed.
Why does the hedge need its own margin?
If yen strengthens, the USD/JPY long loses money while the dollar value of your yen rises. The bank balance cannot fund the derivative automatically, so the position still needs its own collateral.
Monitor both liquidation risk and funding payments, along with changes in your collateral's value.
How do you manage a USD/JPY hedge on Liquid?
- Identify the yen asset or liability, reporting currency, and expected settlement date.
- Open USD/JPY.
- Choose long to hedge dollar-valued yen holdings or short to hedge future yen purchases.
- Calculate the initial notional from the yen amount divided by the exchange rate, adjusting for your hedge percentage.
- Review margin, funding, and execution costs.
- Reassess the hedge after material rate changes, partial payments, or changes in the yen amount, and close it when the exposure ends.
If you need yen delivered on a fixed date, also compare an FX forward or buying the currency in advance. With a perp, you still arrange the yen purchase separately.

Frequently Asked Questions
Do I go long or short USD/JPY to hedge yen holdings?
Go long USD/JPY to hedge yen holdings measured in dollars. Go short to hedge a future yen payment. USD/JPY rises when the yen weakens, which reverses the direction used for EUR/USD.
When should I rebalance a USD/JPY hedge?
Review it after a material exchange-rate move or a change in the yen amount. A linear USD/JPY perp only approximately tracks yen's dollar value, so larger moves can change the hedge ratio.
How do I estimate the initial dollar notional of a yen hedge?
Divide the yen amount by USD/JPY, then multiply by your hedge percentage. At 150, ¥1,500,000 is worth $10,000, so a 50% hedge starts around $5,000 of notional.
Can I hedge USD/JPY on weekends?
Yes. USD/JPY perps use internal pricing while external FX markets are closed. Check the spread and depth before trading, since the weekend quote can differ from your bank's conversion rate.
Does a USD/JPY hedge also protect Japanese share prices?
It covers the yen component of your returns. Changes in the Japanese shares themselves remain a separate risk, and a changing portfolio value can require a currency-hedge adjustment.
