I think everyone forgot how much the USD crashed from 2006 to 2011.
Why?
Fed Rate Cuts: The unfolding credit crisis in the U.S. weakened the dollar. As the Federal Reserve began cutting interest rates in September 2007 to manage the crisis, the dollar lost its yield advantage, making the euro more attractive to investors.
Interest Rate Differentials: While the Fed was cutting rates, the European Central Bank (ECB) was, at times, raising or maintaining higher rates, driving up the value of the euro.
Weak U.S. Economic Data: Slowing U.S. economic growth, particularly in the first quarter of 2007, reinforced fears of a widening economic disparity between Europe and the United States.
Diversification Away from the Dollar: Central banks and investors were increasingly looking for alternatives to the dollar, with the euro serving as the major alternative, boosting its demand.
Eurozone Economic Growth: Robust economic recovery in Germany and overall growth in the eurozone strengthened the currency, with the region's financial markets showing increased vibrancy.
Keep adding my friends. Most importantly, keep your jobs if a massive crash happens, but if you’re smart you’ll profit handsomely from this in 5-10 years.
