In an era of transparent information, are financial crises really harder to happen?

In the past, financial crises were easier to incubate largely because information spread slowly. With underdeveloped communications and low market transparency, information stayed in the hands of a small number of people for a long time. Many risks could accumulate within the system for years, while most market participants were none the wiser. By the time problems were truly exposed, the market often had no time to respond; panic spread rapidly, ultimately evolving into a systemic crisis.

Today’s environment is completely different. Smartphones, the internet, and real-time news mean information can reach across the globe almost instantly. Macroeconomic data, policy changes, and market price fluctuations can all be captured by the market within seconds. Many localized risks are addressed by the market before they even have time to expand. From this perspective, traditional financial crises that rely on information lag to gradually accumulate really have become harder to form.

But it’s not that simple.

More information doesn’t mean more understanding.

When information spreads extremely fast, markets are also more likely to be surrounded by noise. Fake and true rumors get mixed together, emotional contagion accelerates, and market reactions are often amplified. In modern markets, situations like short-term panic, concentrated selling, and instant liquidity contraction are actually more frequent.

The early phase of the 2020 pandemic is a typical example. In the space of just one month, the U.S. stock market triggered four circuit breakers. It wasn’t that the economic fundamentals collapsed suddenly within weeks; rather, the market rapidly formed consensus panic under dense information shocks. When everyone reacts in the same way at the same time, market volatility gets magnified to the extreme.

The deeper problem actually comes from the financial system itself becoming more complex.

During the 2008 financial crisis, many structured products such as CDOs and CDS were widely traded across the global financial system. In theory, all relevant information was public, but not many people truly understood these structural risks. Many institutions only looked at credit ratings, yields, and model outputs, without really understanding how these products amplify risk to each other under extreme conditions. By the time the problems erupted, the entire system realized that risk had accumulated to a degree that was hard to control.

Similar situations have still occurred in recent years.

The 2022 UK pension crisis is one example.

At the time, the UK government proposed a large-scale tax-cut plan. The market quickly questioned fiscal sustainability, and UK government bond yields surged sharply in a short period. Many pension institutions adopted so-called LDI strategies, using derivatives to magnify leverage in order to increase yields. When bond prices fell, these institutions needed to continuously post additional margin. Once liquidity ran short, they were forced to sell government bonds, pushing yields higher still, creating a vicious cycle.

During the most tense days of the crisis, many traders and analysts stared at the interest-rate curve and changes in government bond yields almost through the night. The issue wasn’t that there wasn’t enough news; it was that many people only truly realized how these structures were interlocked once the crisis happened.

Technology has indeed increased information transparency and made the market respond to risk faster. But at the same time, the financial system has become more complex, leverage structures more hidden, and the chain of funds more tightly linked. Some risks no longer need years to accumulate; they may instead concentrate and erupt within a very short time.

So today’s question is no longer just whether information is public.

The real issue is:

How many people truly understand the structures behind these pieces of information.
