Theoretically, the injection of money into the market will weaken the value of the currency for the short term. But if this stimulus package manages to generate the economy to the optimum level, the value of the currency will return strong.
Specifically, the value of the US Dollar is currently weak against several other major currencies such as the Euro, Pound, Australian Dollar and New Zealand Dollar. There will most likely be a retracement in some pairs such as AUD / USD and NZD / USD as the price approaches the important resistance level of the price.
