Embargoing is an option in the diplomacy screen that allows a country to leverage their trade power against another nation's, decreasing that nation's trade power in shared trade nodes. The trade screen shows icons for each nation embargoed and those embargoing your nation. Placing the mouse over each nation icon breaks down the penalties in each shared trade node. Embargoing a country has the following effects: The defending country suffers a penalty to trade power in all trade nodes that both countries have power in. The base magnitude of the penalty is half of the attacker's trade power share in the trade node before the embargo. This penalty stacks multiplicatively with other modifiers. The defending country's opinion of the attacking country is modified by -15. The defender also gains a Trade Dispute casus belli against the attacker unless the embargo is mutual. The attacking country's trade efficiency suffers a -5% penalty unless the defender is a rival. Embargoes do not count against the Diplomatic Relation limit. The attacking country gains up to +10 power projection if the target is a rival, the amount depending on how severely the embargo affects the target's trade.
