Final answer:
The war between Russia and Ukraine has disrupted the global economy, causing shortages, food price increases, and challenges in the banking and trade sectors.
Step-by-step explanation:
The war between Russia and Ukraine has had a significant impact on the global economy. One major effect has been the disruption of the supply chain system, leading to shortages of raw materials and produced goods. Additionally, the war has caused a rise in global food prices and exacerbated hunger in countries that rely on Ukraine for wheat and other agricultural products. The conflict has also put strain on the banking system and led to trade disruptions and economic sanctions. These factors have contributed to a challenging economic environment worldwide.
