Since it is taking fewer dollars to buy a ruble, the exchange rate is depreciating.

Both the debt-to-equity and debt-to-capital ratios will be lower under the temporal method versus the current rate method if a foreign currency is depreciating. Under both methods, long term debt and accounts payable are both translated at the current exchange rate, so those are the same.

Equity under the temporal method is effectively translated at a mixed rate under the temporal method, and the current rate under the current rate method. Since the currency is depreciating, the equity value will be higher under the mixed rate scenario. With the same debt and higher equity, the temporal method will lead to a lower debt-to-equity ratio than the current rate method.

Assets under the temporal method are also effectively translated at a mixed rate under the temporal method, and the current rate under the current rate method. Since the currency is depreciating, the asset value will be higher under the mixed rate scenario. With the same debt and higher assets, the temporal method will lead to a lower debt-to-capital ratio than the current rate method
