Banking has not always had global rules.
Before the 1970s, banks were regulated mostly within their own countries. As banks expanded internationally, this became a problem. A failure in one country could quickly affect others.
In 1974, the collapse of a German bank exposed this risk. Regulators realized that banking instability could spread across borders. In response, central banks formed the Basel Committee on Banking Supervision to create common standards.
The Core Problem
Banks are inherently fragile:
- they take deposits (short-term money; sometimes they borrow short-term)
- they lend long-term
- they operate with leverage
If loans go bad or depositors panic, banks can fail. When multiple banks fail together, the entire economy is affected.
This risk is amplified by the credit cycle:
- Expansion. Economic activity increases and borrowing begins to rise.
- Credit boom. Banks lend aggressively and credit grows rapidly.
- Asset inflation. Prices of assets like property and stocks increase.
- Risk buildup. Debt levels rise and lending standards weaken.
- Shock. An economic disruption or stress event hits the system.
- Deleveraging. Borrowers and banks reduce debt and exposure.
- Credit contraction. Lending declines and access to credit tightens.
- Recovery. Balance sheets stabilize and growth gradually resumes.
Banks tend to lend aggressively in booms and pull back in downturns, making the cycle more extreme.
The Basel Response
In 1988, regulators introduced Basel I, requiring banks to hold capital relative to risk. This was the first global attempt to ensure banks could absorb losses.
Later frameworks improved this idea, but a major wake-up call came during the 2008 Global Financial Crisis, when many banks were found to be underprepared—ultimately leading to stricter rules under Basel III — How Modern Banking Rules Make Banks Safer.
What Basel Is Really About
Basel is not just a set of rules.
It is a global framework designed to:
- strengthen bank resilience
- reduce systemic risk
- prevent financial crises from spreading
Key Insight
Banks are not ordinary businesses—they are part of a country’s financial infrastructure.
When they fail, the effects spread quickly.
So Basel exists to ensure one thing:
The banking system can absorb shocks without collapsing.
