There is no limit to nominal growth. Consider the GDP formula: GDP = Consumption + Investment + Government Spending + Net Exports A sovereign currency issuing government can directly grow nominal GDP as much as they like simply by some combination of direct investment, spending, or reducing imports and funding it by creating new money. Whether or not this "growth" will reflect greater productivity, general well-being, or even be net positive after accounting for inflation is another matter entirely.
