Why is the US dollar so important?

📘 In Brief The US dollar is so important because it is the undisputed leading currency of the global economy. Around 60 percent of all global currency reserves are held in dollars, and the majority of international trade – from oil to electronics – is settled in dollars. That means: anyone who wants to import or export needs dollars, regardless of whether the US is involved. This special status is based on trust and stability. The US has deep, liquid financial markets, an independent central bank, and a long history of solvency. Moreover, the dollar is the most important safety net in crises: when panic breaks out, investors worldwide buy US government bonds because they are considered the safest haven – which further strengthens demand for the dollar. This creates a cycle: because everyone uses dollars, everyone wants to hold dollars, which keeps the dollar strong and spreads its use even further. This dominance gives the US enormous power, for example in sanctions, since it can control access to the dollar system. At the same time, it makes the US vulnerable, because a weakening of the dollar would have global consequences – a reason why countries like China or Russia are looking for alternatives, but so far have found no equivalent substitute. 🔍 Why This Matters The US dollar dominates the global financial system primarily due to its role as the world’s reserve currency.

Added to this is the sheer liquidity and depth of US financial markets, particularly the government bond market, which is considered a safe haven in times of crisis.
