What would be the effect on COGS if the local currency is depreciating/appreciating under temporal/current method and FIFO/LIFO?

If using FIFO for a local currency that is depreciating, COGS should be lower than LIFO?

If using FIFO for a currency that is appreciating, COGS should be higher than LIFO?

If using Current method for a currency that is appreciating, COGS should be higher than with the temporal method?

If using Current method for a currency that is depreciating, COGS should be lower than with the temporal method?
