Opinion | Ukraine war: sanctions on Russia show the power of a weaponised US dollar
- While Russia engages in physical war, the United States and its allies are engaging in a proxy war through sanctions and supplying aid to Ukraine
- Money is at the root of all success in warfare – you fight for money, and you need money to fight

The war in Ukraine is clearly a game-changer. It has upended many assumptions on who is strong militarily and who is weak in the media war. It will be remembered as the end of the peace dividend era, when the world enjoyed decades of global peace and stability without major wars.
Geopolitical strategist George Friedman said the biggest lesson from the current war has nothing to do with Russia or Ukraine; rather it was that “the United States has demonstrated that perhaps the most powerful weapon in the world is the weaponised dollar”.
The physical war is being fought by Russia and Ukraine while the US and Nato are engaging in a proxy war, using financial sanctions and supplying arms to help Ukraine fight to the last. As the US dollar accounts for about 40 per cent of global trade invoicing and about 60 per cent of official reserves, there is no question it has more clout than the euro, yen or yuan.
Why does the US dollar have such advantages? The standard argument is that it is a unit of account for global credit and invoicing, a means of payment and store of value, bringing the issuer privileges by being able to issue currency at will.
