Global inflation has become a major issue in the post-pandemic era, with impacts felt almost all over the world. Industry, small businesses, and the general public face significant economic challenges due to surging prices of goods and services. Various factors contribute to this inflation, including supply chain disruptions, surging demand, and expansionary monetary policy. One of the main causes of global inflation is supply chain disruptions that occurred during the COVID-19 pandemic. Many factories closed temporarily and transportation of goods was disrupted, causing delays in production and distribution. As the economy begins to recover, high demand meets limited supply, pushing prices up. For example, the semiconductor industry experienced a crisis, causing a spike in electronics prices. In addition, the economic stimulus provided by governments around the world to help people and businesses survive during the crisis also triggers inflation. Loose monetary policy, including low interest rates and asset purchases, provided a boost to consumer demand. However, when demand increases but supply cannot keep up, inflation increases. On the energy side, surging oil and gas prices play an important role in global inflation. The war in Ukraine and other geopolitical tensions have disrupted energy supplies, pushing energy prices to record levels. Rising energy costs not only impact transportation costs, but also the costs of producing goods and services. Inflation also affects people’s purchasing power. Rising prices for food, housing and daily necessities mean that many families struggle to meet basic needs. This fuels social dissatisfaction and increases challenges for the government in maintaining economic stability. In many countries, central banks face a dilemma in responding to inflation. Raising interest rates can help control inflation, but it can also slow economic growth and increase the risk of recession. For example, the US Federal Reserve and the European Central Bank have begun to indicate the possibility of tightening monetary policy, but these steps must be taken with caution to avoid wider negative impacts. Certain sectors such as construction and transportation experience a more significant impact from inflation. Rising prices of building materials and labor costs are creating challenges for new projects, potentially slowing economic recovery. On the other hand, some sectors, such as technology, continue to adapt to the situation, often by increasing innovation to cope with rising costs. In a global context, inflation knows no geographical boundaries. Developing countries also face greater challenges due to their dependence on imported goods. With fluctuations in global commodity prices, many of these countries are caught in inflationary turmoil that can disrupt long-term economic growth. In the future, it is important for the government and economic actors to develop effective strategies to deal with global inflation. Fiscal and monetary policies must work in synergy to ensure price stability without sacrificing growth. Innovative approaches to improving supply chain efficiency and diversifying energy sources can help reduce dependency and the impact of inflation. Overall, global inflation in the post-pandemic era is a complex challenge. A balance between controlling inflation and economic recovery is key in dealing with this situation. Through a deep understanding of inflation dynamics and appropriate responses, global economic sustainability can be maintained for the welfare of society.
