Although the economic cycle is unpredictable in time and amplitude, it has been fully considered and applied in organizational life. In some countries, such as the United States, political factors are fixed, such as the determination of election day is not subject to change. But in other countries, such as the UK, the political cycle is relatively flexible, and the government has the right to choose the specific election schedule before the latest election deadline.

The intervention may be either oral or practical. Oral intervention is only in the form of statements (statements) made by the authorities to influence the value of a certain heavy currency. The actual intervention refers to the use of xauusd reserves and foreign exchange reserves by the authorities to purchase the domestic currency and increase its value by increasing the demand for the domestic currency. However, because xauusd and foreign exchange reserves are limited, unrestricted intervention or support of a currency will inevitably lead to the exhaustion of xauusd and foreign exchange reserves, so this kind of intervention is impossible to continue indefinitely.
