Climate Impact on Economic Stability

Climate change is often understood as an environmental issue. We picture it in terms of melting polar ice, burning forests, or floods inundating settlements. Yet in truth, climate change extends far beyond environmental concerns.

It has become a serious economic problem, one with the potential to shake the macroeconomic stability of nations. The physical risks arising from climate change are no longer an abstract future threat, but a reality already affecting economic growth, investment, food prices, and public welfare.

A study by global research firm MSCI (Morgan Stanley Capital International) emphasises that the impact of climate change does not stop at visible physical damage. Destruction of buildings, factories, roads, or farmland represents only a fraction of the problem.

When these physical risks are calculated in a macroeconomic context, losses can multiply many times over. Production disruptions, supply chain interference, declining labour productivity, and weakened consumer spending are cascading effects far greater than the value of damaged assets alone.

In macroeconomics, events that disrupt the functioning of an economy are termed shocks. Climate change can act as a shock that strikes both the supply side and the demand side simultaneously. When floods paralyse industrial zones, production halts and the supply of goods declines.

When drought depresses harvests, food prices surge and purchasing power weakens. At the same time, uncertainty from extreme weather causes investors to postpone expansion. In such circumstances, the economy faces pressure from multiple directions at once.

Indonesia is among the countries most vulnerable to the physical risks of climate change. As an archipelagic nation with an extensive coastline, Indonesia faces threats from rising sea levels, tidal flooding, and increasingly intense tropical storms.

Meanwhile, shifting rainfall patterns and temperatures affect the agricultural sector that underpins the livelihoods of millions. Each time the planting season is disrupted or harvests decline, the impact is felt not only by farmers but also by urban consumers who must pay higher prices for basic necessities.

Within the framework of gross domestic product, such disruptions translate into slower growth. When production falls and consumption weakens, economic growth figures come under pressure. The government must also allocate substantial budgets for disaster response, infrastructure rehabilitation, and social assistance.

Fiscal space that should be directed towards long-term development ends up being absorbed by disaster recovery. Over the long term, this pattern can impede the economic transformation process currently under way.

Classical economic theory explains that growth is underpinned by capital accumulation, labour force expansion, and technological progress. Yet climate change erodes all three simultaneously. Physical capital is damaged by disasters.

Workers lose working hours due to extreme temperatures or health problems. Meanwhile, the high cost of adaptation reduces the ability of businesses to invest in innovation. If these conditions persist, long-term growth potential will decline.

A concrete example can be seen in the agricultural sector. When the El Niño phenomenon extends the dry season, rice production falls. Supply contracts and rice prices rise. Food inflation increases and erodes the purchasing power of low-income communities.

The government may be compelled to open the import tap to maintain price stability. Yet increased imports mean pressure on the trade balance. In a single chain of events, climate risk that was initially a natural phenomenon transforms into a national economic problem.

A similar pattern occurs in coastal areas. Rising sea levels and tidal flooding damage fish ponds, homes, and public facilities. Local economic activity declines. Community incomes fall and consumption weakens. If the affected area is an industrial centre or port, distribution disruptions can spread to other regions. In an interconnected economy, local disruptions easily escalate into national pressure.

The labour sector is not immune from these effects either. Workers in construction, agriculture, and manufacturing are highly dependent on weather conditions. Heatwaves or extreme rainfall reduce effective working hours.

Productivity falls and production costs rise. In economic theory, declining productivity means a reduction in potential output. If this persists over time, national income will be permanently affected.

The physical risks of climate change also have implications for the financial sector. Banks and financial institutions hold exposure to assets and projects in disaster-prone areas. If these risks are not properly accounted for, the stability of the financial system may be compromised.

Global investors are paying increasing attention to climate risk factors in their investment decisions. Countries perceived as inadequately prepared for climate change risk facing higher borrowing costs and reduced capital inflows.

All of this demonstrates that climate change is not merely a standalone environmental issue. It has become a fundamental factor in economic planning. Consequently, future macroeconomic policy cannot disregard physical climate risks. Development planning must incorporate climate resilience as a core component, not an afterthought.

Indonesia needs to strengthen its infrastructure to be more disaster-resistant. Irrigation systems, dams, embankments, and drainage must be designed to cope with increasingly unpredictable weather patterns. Investment in renewable energy is also an important part of the long-term strategy. Beyond reducing emissions, energy diversification strengthens resilience against external shocks.

The government also needs to expand social protection for vulnerable groups.
