How expansionary monetary policy influences global markets

From economic crises to the role of monetary stimulus

During the COVID-19 pandemic in 2020, the global financial system faced an unprecedented paralysis. With businesses shuttered, millions of people out of work, and the economy at a complete standstill, monetary authorities around the world had to act decisively. The Federal Reserve in the United States, the European Central Bank (BCE) in Europe, and other similar institutions launched massive interventions to inject liquidity into the markets. This approach represents a practical application of what central bankers call quantitative easing, or more simply QE.

What is quantitative easing: the fundamental mechanism

QE is a monetary policy strategy that central banks implement when traditional methods are no longer sufficient. Instead of lowering interest rates ( which cannot go below zero), the central bank intervenes directly in financial markets by purchasing assets in large quantities.

How does it work in practice? Central banks turn to financial institutions and commercial banks to procure various assets: government bonds, mortgage-backed securities, or other financial instruments. In exchange for these purchases, they inject large amounts of fresh cash into the banking system. This increase in the monetary base allows banks to have more resources to lend to businesses and citizens, while simultaneously reducing the costs of financing.

Why central banks resort to these interventions

The economy has difficult moments, periods in which it struggles to progress. In these circumstances, monetary authorities seek to give a boost to the system. When credit gets blocked and investors become frightened, QE acts like an injection of confidence and liquidity into the market. This allows companies to finance expansion projects, governments to support infrastructure, and families to access credit on more favorable terms.

Consequences on traditional financial markets

The effect of QE on financial markets is profound and far-reaching. The massive injection of money reduces general interest rates, making bonds less attractive while pushing investors towards alternatives with potentially higher yields, such as stocks. Companies, finding money at low cost, increase investments and profits, thereby supporting stock prices.

At the same time, monetary expansion tends to weaken the value of the national currency. This has ambivalent effects: it promotes exports abroad, but increases import costs and heightens internal inflationary pressures. Overall, QE completely reshapes the architecture of financial markets, influencing asset prices, financing conditions, and exchange rate dynamics.

The effects on digital currency

The link between QE and cryptocurrency markets is the subject of lively discussion among experts and operators. Part of the financial community argues that when governments massively expand the supply of traditional currencies, assets like Bitcoin become more attractive as they represent an alternative store of value that is independent of central monetary policy.

On the other hand, some analysts believe that cryptocurrencies move according to their own dynamics, influenced more by technology and adoption than by interventions from traditional central banks. The relationship remains complex and deserves further empirical observation.

The intrinsic risks of this strategy

Although QE can be effective in providing immediate support to the economy, it carries significant risks. The first is inflation: when too many banknotes circulate in a real economy with a limited supply of goods and services, prices inevitably rise, eroding purchasing power.

A second danger is the creation of speculative bubbles. With abundant money and low interest rates, investors may chase high returns in overvalued sectors, from stocks to the real estate market, generating financial instability.

Finally, prolonged QE can distort the efficient allocation of resources, funding unprofitable companies and delaying the necessary structural adjustments to the economy.

Conclusion: a powerful tool but not without costs

Quantitative easing is a formidable weapon in the hands of monetary authorities, especially in times of crisis. When the economy stalls and the financial system risks collapse, as happened in 2020, QE has proven capable of containing immediate damage and stabilizing markets.

However, understanding what QE is also means recognizing the trade-offs it entails. Inflation, financial bubbles, and market distortions are real and potentially serious side effects. For investors and market participants, including those following the crypto markets, QE remains a central phenomenon that shapes price behavior, the cost of money, and global asset allocation strategies.
