Supply and Demand Shocks – What Happens When Markets Get Blindsided

Occasionally, the economy experiences events or developments that disrupt the conventional dynamics of supply and demand. The repercussions of such disturbances can persist for an extended period, thereby affecting the conduct of individuals, enterprises, and governmental bodies. This can result in spikes in gas prices, loss of jobs, and inflation.

Everyday there are situations or decisions that change the normal supply flow of one or more products. While positive supply shocks can boost economic growth, extreme negative shocks can cause lasting issues. The COVID pandemic has been the largest supply shock globally in recent times. Many companies' procurement departments are still trying to figure out how their supply chains, which have been impacted by the virus, work. 

A demand shock is a sudden drop in demand caused by some event. The financial crisis of 2008 is an example. When the housing market collapsed, people also stopped heavy spending simultaneously. As mentioned previously, the duration of the consequences of these shocks can be extended. 

Instances have arisen where both supply and demand have concurrently experienced shocks, with the COVID19 pandemic serving as a recent illustration. The recovery was unpredictable and disorderly due to the simultaneous events. Policy makers were unsure of the best moves to take in order to return to normal. The US government employed several measures to resolve the problem, including stimulus checks, low rates by the Federal Reserve, and relief programs. However, these actions in the long run brought about inflation as demand revived at a faster rate than supply. 

Economists and policymakers must remain vigilant about shocks. They should anticipate these events, as they reveal the true strength and stability of an economy and help prevent future crises like COVID-19. This is also the reason why economies should be flexible and capable of changing. For example, when an economy is heavily reliant on a singular commodity, an adverse shock can precipitate its collapse, as evidenced by the oil crisis in Venezuela. Nations must be concurrently prepared for such events, which is why the term "shocks" aptly describes these phenomena. Some things can be foreseen and thus avoided, but on the other hand, there are things that are unavoidable and may occur unexpectedly. People must be prepared to make changes. 

Ultimately, supply and demand shocks test the resilience of an economy, highlighting the readiness of governments, consumers, and producers to adapt to sudden changes. They serve as a test of the readiness of governments, consumers, and producers to adjust to sudden changes, and they make us aware that even the most complex systems like the world economy can be unexpectedly tampered with.
