If there is a peace deal, and it is perceived to be sustainable, then
it is good for inflation;
1. Oil price will go down;
2. food price may go down (both Russian and Ukraine are big producer)
3. Airfare price will come down (which is the bigger driver in latest CPI), because the Russian space will reopen for US and others's airlines
4. the war's disruption to supply chain and trade will be normalized somewhat, which will help reduce the cost
5. with the geopolitical risk subsiding, the inflation expectation will subside.
SO it is a high stake.
Not a trade recommendation, nor a prediction of what will happen
