If you've ever questioned why the currency markets shift suddenly due to a central bank announcement, quantitative easing may be at work. QE is a monetary policy instrument in which Central Banks buy long-term government bonds and other financial instruments to increase liquidity in the economy. Think of it as the central bank turning on the money spigot, but under a controlled process.
The ultimate purpose? Strengthen economic activity when other monetary items are no longer effective. Central banks utilise QE to lower interest rates, facilitate borrowing at a lower rate, and incentivise business and consumers alike to once again begin spending and investing. It's not merely about printing money for the sake of printing money! There is always a reason for every purchase.
The 2008 financial crisis comes to mind. The Federal Reserve instituted massive QE programs to support crashing markets and try to prevent a total economic collapse. Banks were frozen, credit was running dry, and the Fed needed heavier medicine than simply dropping interest rates.
How QE Works
Let's explain the mechanics: when a central bank decides it will use QE, it begins buying assets, typically government bonds. The purchases do inject new money into the financial system. Now, banks have more reserves sitting around, and all that liquidity pushes bond yields lower. Lower yields mean lower borrowing costs for businesses and homebuyers.
When banks have large reserves of cash, they're more likely to lend it out. Credit spreads more evenly across the economy. Businesses can borrow to expand. Consumers can finance purchases. The entire economy starts to move again, at least in a theoretical sense. The European Central Bank's Quantitative Easing (QE) program of 2015 is a clear example.
QE's Impact on Forex and Global Markets
This is where it becomes really intriguing for traders. Typically, QE (quantitative easing) will weaken the domestic currency as it expands the money supply. More currency in circulation means each currency unit is worth less. When the Fed started QE1, the dollar declined substantially, while emerging market currencies strengthened as investors looked for better returns.
And the effects will extend far beyond exchange rates. Stock markets typically rally during QE as investors chase yield into riskier assets, as bonds are yielding almost zero income. Commodities such as gold may rally as investors look to hedge against inflation. Real estate markets also begin to heat up as mortgage rates decline. It’s all interconnected.
The Risks of QE
QE is not a panacea. Central banks realise this, even if the markets can sometimes forget. One major risk that accompanies QE is inflation. When you flood an economy with too much liquidity, prices can go up exponentially. Liquidity has to go somewhere, and if it is chasing too few goods, prices can go up on everything.
Asset bubbles are another concern of introducing QE into monetary policy. When QE discourages traditional investment via bond markets, money flows into equities and housing, creating artificial price increases that stretch beyond valuations. When QE is ongoing, the financial imbalances become larger and larger.
QE Versus Other Monetary Tools
So, why QE and not just a rate cut? The answer is that sometimes rates are zero. There’s no more room to cut rates, and that’s when central banks come in with QE. The traditional way monetary policy operates is by increasing and decreasing the interest rate.
For example, central banks increase rates to reduce inflation and decrease rates to encourage borrowing. This works perfectly until rates hit zero. Once you reach an effective zero lower bound, that’s when traditional policy becomes ineffective or entirely useless. QE is a way to continue engagement when cutting rates has reached its limit.
What This Means for Your Trading
Now let's pull this all together. QE is a monetary policy tool the central bank utilizes that adds liquidity by purchasing long-dated assets. It lowers the costs of borrowing, stimulates economic activity, and usually results in a weaker domestic currency. It creates effects in global markets from stocks to commodities to forex pairs.
The dangers are real. If QE progresses too far, inflation can take off. Asset bubbles can develop when the money looks for a return. The effectiveness diminishes, and unwinding can be messy. This has been evident in Japan's decades-long experiments and the Fed's careful approach to unwinding its balance sheet.
