adverse-move stress card from currency roles and rate directions through local price, settlement, costs, contribution, decision, and restoration — Original adverse-move stress card diagram using invented values and no customer or transaction records.

Preserve like-for-like automatic pricing

Both fixtures use automatic pricing so the comparison isolates the weaker settlement rate and higher absorbed duty rather than changing the storefront method at the same time.

To study a manual rate, open a separate packet and document that Shopify does not add the conversion fee to the manually converted customer price, while the fee can still be deducted from payout.

Measure the adverse driver, not a narrative

The signed contribution difference is USD 7.20 under the invented packet. Attribute it numerically to the settlement-rate change and duty increment rather than calling the scenario simply worse.

Keep payment, refund, product, fulfillment, method, currency roles, and order grain fixed unless the analysis explicitly identifies another changed driver.

Freeze the local price

If the presentment price stays EUR 93.84 but the capture-time settlement rate falls from 1.08 to 1.02 USD per EUR, store-currency revenue falls while USD product costs remain. Higher seller-absorbed duties can deepen the contribution decline even though the storefront price did not change. Change settlement and duty assumptions explicitly while holding the customer price packet constant. Checkpoint 1 in the adverse-move stress card records amount, currency, rate direction, transaction event, source date, owner, and accepted version before any output is interpreted.

For freeze the local price, keep store, presentment, and payout currencies; base and local price; pricing and settlement rates; adjustment; rounding; payment and conversion fee; product and fulfillment cost; duty responsibility; refund exposure; market configuration; transaction date; owner; reviewer; and restoration evidence as distinct fields.

Lower the settlement rate

If the presentment price stays EUR 93.84 but the capture-time settlement rate falls from 1.08 to 1.02 USD per EUR, store-currency revenue falls while USD product costs remain.

For lower the settlement rate, keep store, presentment, and payout currencies; base and local price; pricing and settlement rates; adjustment; rounding; payment and conversion fee; product and fulfillment cost; duty responsibility; refund exposure; market configuration; transaction date; owner; reviewer; and restoration evidence as distinct fields.

Recalculate captured gross

If the presentment price stays EUR 93.84 but the capture-time settlement rate falls from 1.08 to 1.02 USD per EUR, store-currency revenue falls while USD product costs remain. Higher seller-absorbed duties can deepen the contribution decline even though the storefront price did not change. Change settlement and duty assumptions explicitly while holding the customer price packet constant. Checkpoint 3 in the adverse-move stress card records amount, currency, rate direction, transaction event, source date, owner, and accepted version before any output is interpreted.

For recalculate captured gross, keep store, presentment, and payout currencies; base and local price; pricing and settlement rates; adjustment; rounding; payment and conversion fee; product and fulfillment cost; duty responsibility; refund exposure; market configuration; transaction date; owner; reviewer; and restoration evidence as distinct fields.
