Currency strength of a nation thus depends on the integrity of and trust in a state (Sun), the government and the policies it may implement (Moon) as well as the income and wealth of the country. The power of the state may be linked to the size and endowments of the state and its track record in defending its interests in the past. The policies may either help or hinder the wealth generating potential of the economy, including the operation of markets. Markets may be given an excessively free rein or be constrained to the point that they do not yield the optimal outcome. The laws of the country set the rules of the game that either help to resolve ambiguities of what is fair for investors and consumers or they may be unclear and/or biased, such that they favour either seller or buyer at the expense of the other. It is a complex matter. That said, we can look to the natal potential of a horoscope to see the bottom line, in terms of the expected long term trend of currency strength. Over shorter time spans, the astrological analysis of the external value of a currency are linked to the changes between the major or sub-periods of the planets and significant events indicated by transits, which bring either advances or setbacks.
We can now compare and contrast the evolution of the long term value of the UK Pound Sterling and the US dollar in terms of an analysis of their respective horoscopes. The accompanying chart shows the long term trend. The value of the UK Pound has fallen in a rather steady manner for almost one century with respect to the US dollar. This is not surprising as the USA has been in ascendancy in this period while the Sun has set on the British empire. After World War II, the international order of the British Empire, referred to as the Pax Brittannica, was replaced by the USA assuming the mantle in what became known as the Pax Americana.
