Why Growth Does Not Always Strengthen Financial Markets? The Role of Institutions in the Association of Southeast Asian Nations
This study of nine ASEAN economies from 1997 to 2021 reveals that institutional quality acts as a critical conditioning factor in the growth–finance nexus, where economic growth significantly expands credit availability in economies with weaker institutions but yields diminishing returns in those with stronger, more developed financial systems.

Imagine the economy as a giant garden. For a long time, economists believed that if you just made the garden grow bigger (economic growth), the watering system (financial markets) would automatically get deeper and stronger to support all the new plants. The idea was simple: More growth = More money available to borrow.
However, this new study looks at nine countries in Southeast Asia (ASEAN) and finds that this "automatic" rule doesn't work everywhere. Sometimes, when the garden grows, the watering system gets better. Other times, the garden gets huge, but the watering system stays exactly the same.
The paper argues that the missing ingredient isn't the size of the garden, but the quality of the garden's rules and fences (what the authors call "Institutional Quality").
Here is the breakdown of their findings using simple analogies:
1. The "Empty Pipe" vs. The "Full Pipe" Analogy
The study suggests that the relationship between growth and money availability depends on how "developed" the country's rules are.
In countries with weaker rules (like Cambodia, Laos, Vietnam):
Imagine a water pipe that is currently empty and clogged. When the economy starts growing (the garden gets bigger), it creates a sudden, massive demand for water. Because the pipe was previously empty, this new demand forces the system to open up rapidly. The water starts flowing freely.- The Finding: In these places, economic growth acts like a powerful pump that suddenly fills the empty pipes. Money becomes much easier to get when the economy is doing well because there was so much unmet demand before.
In countries with strong rules (like Singapore, Malaysia, Thailand):
Imagine a water pipe that is already a massive, high-tech, fully pressurized super-highway. It is already full of water, and the system is running perfectly.- The Finding: When the economy in these places grows, it doesn't really change the water flow. The system is already so efficient and deep that a little extra growth doesn't make the pipes any bigger. The connection between "growing the economy" and "getting more money" is broken because the money is already there, regardless of the current growth cycle.
2. The "Traffic Light" Metaphor
Think of Institutional Quality (the strength of laws, lack of corruption, and fair courts) as the traffic lights and road signs for money.
- Weak Institutions (Broken Traffic Lights): When the economy speeds up (growth), money rushes through the streets chaotically. Because the "traffic lights" (rules) are broken, the rush of growth forces a temporary, frantic expansion of credit to fill the void. It's a boom, but it's tied directly to the speed of the economy.
- Strong Institutions (Perfect Traffic Lights): When the rules are perfect, the flow of money is smooth and constant. It doesn't matter if the economy speeds up or slows down slightly; the "traffic" of money keeps flowing steadily because the system is reliable. Growth doesn't need to "push" the money; the money is already moving efficiently.
3. The "Surprise" Discovery
The most surprising part of the paper is that the authors found a negative link between good rules and the impact of growth.
It sounds counterintuitive: You might think, "Better rules should make growth help finance more." But the study found the opposite.
- The Logic: In places with bad rules, growth is the only thing that wakes up the financial system. It's the spark.
- In places with good rules, the financial system is already awake and working. So, adding more growth doesn't make it work better or faster; it just keeps it running as it always has. The "spark" of growth is no longer needed to light the fire because the fire is already burning brightly.
4. What This Means for Real People
The paper translates these findings into three simple takeaways:
For Business Owners:
- If you are in a country with weaker rules, you should know that your access to loans is tied to the economy's mood. When the economy is booming, you can easily get money. When it slows down, that money might vanish quickly. You need to save up cash during the good times to survive the bad times.
- If you are in a country with strong rules, your access to loans is stable. It doesn't matter if the economy has a good year or a bad year; the banks will likely keep lending because the system is trustworthy.
For Investors:
- Don't just look at how fast a country's economy is growing. Look at how good its "traffic lights" (laws and anti-corruption measures) are. In countries with weak rules, a growing economy is a great time to invest because money is flowing. In countries with strong rules, the economy's growth rate matters less because the money system is already solid.
For Government Leaders:
- If you want your country's financial system to get better, just growing the economy isn't enough. You have to fix the "traffic lights" first. You need to make sure contracts are enforced, corruption is low, and laws are clear. Without fixing these rules, any money you get from economic growth will be temporary and unstable.
Summary
The paper concludes that Economic Growth does not automatically fix Financial Markets.
- In under-developed systems, growth acts as a catalyst that forces the financial system to open up.
- In mature systems, growth is irrelevant to the depth of the financial system because the system is already deep and stable.
The "secret sauce" that determines which of these two scenarios plays out is Institutional Quality. Without strong rules, growth creates a temporary boom. With strong rules, growth is just a background detail in a system that already works.
