I think war always bring bad impact to the world economy. imagine this, build a building from destructed building is more expensive rather than build a building on empty land. war will make the cost for development increase a lot, it will really slow the progress and as human we maybe don't have enough power or resource to anticipate bad things from nature that maybe come in the future.
Generally this is true, but this is only felt by countries that are at war because the destruction you are referring to only occurs in certain areas and not globally. But if we look at the negative impacts that can spread globally, there are also high prices for basic necessities or raw materials that have not been processed and the difficulty of having access to countries that are at war to make marketing there, so this has become a very basic obstacle.
Apart from that, if several countries are facing war and usually these countries very often produce natural resources in large quantities and the results of these natural resources are raw materials for making certain products which are often needed by all communities, this will also have an impact. which is even worse. Namely an increase in the price of raw materials to two or three times the usual because when raw materials or natural resources become scarce, the price will continue to soar and companies that often buy these raw materials will also find it difficult to produce more.
