what is a global recession 
a global recession is an extended period of economic decline around the world a global recession involves more or less synchronized recessions across many national economies as trade relations and international financial systems transmit economic shocks and the impact of recession from one country to another the international monetary fund imf uses a broad set of criteria to identify global recessions including a decrease in per capita gross domestic product gdp worldwide according to the imf s definition this drop in global output must coincide with a weakening of other macroeconomic indicators such as trade capital flows and employment 1understanding global recessionsmacroeconomic indicators have to wane for a significant period of time to classify as a recession in the united states it is generally accepted that gdp must drop for two consecutive quarters for a true recession to take place based on analysis by the national bureau of economic research nber which is considered the national authority in declaring and dating business cycles 2 for global recessions the imf plays a role similar to the nber while there is no official definition of a global recession the criteria established by the imf carry significant weight because of the organization s stature across the globe unlike the nber the imf does not specify a minimum length of time when examining global recessions in contrast to some definitions of a recession the imf looks at additional factors beyond a decline in gdp there must also be a deterioration of other economic factors which include trade capital flows industrial production oil consumption the unemployment rate per capita investment and per capita consumption 1ideally economists would be able to simply add the gdp figures for each country to arrive at a global gdp the vast number of currencies used throughout the world makes the process considerably more difficult though some organizations use exchange rates to calculate the aggregate output the imf prefers to use purchasing power parity ppp that is the amount of local goods or services that one unit of currency can buy rather than the amount of foreign currency it can buy in its analysis 3up until 2020 according to the imf there have been four global recessions since world war ii beginning in 1975 1982 1991 and 2009 in 2020 the imf declared a new global recession which it dubbed the great lockdown caused by the widespread implementation of quarantines and social distancing measures during the covid 19 outbreak this is the worst global recession on record since the great depression 14the impact and severity of the effect of a global recession on a country vary based on several factors for example a country s trading relationships with the rest of the world determine the scale of impact on its manufacturing sector on the other hand the sophistication of its markets and investment efficiency determine how the financial services industry is affected the interconnection of trade relations and financial systems among countries can help to spread an economic shock in one region into a global recession this process is known as contagion example of a global recessionthe great recession was an extended period of extreme economic distress observed around the world between 2007 and 2009 world trade plunged by over 15 between 2008 and 2009 during this recession the scale impact and recovery of the downturn varied from country to country the u s experienced a major stock market correction in 2008 after the housing market collapsed and lehman brothers filed for bankruptcy 5 economic conditions had already turned down by the end of 2007 and major indicators such as unemployment and inflation hit critical levels with the collapse of the housing bubble and ensuing financial crisis the situation improved a few years after the stock market bottomed in 2009 but other nations experienced much longer roads to recovery over a decade later the effects can still be felt in many developed nations and emerging markets according to economic research conducted for the nber the united states would have suffered limited shocks to its economy if the 2008 recession had not originated within its borders 6 this is mainly because it has limited trading relationships with the rest of the world in comparison to the size of its domestic economy on the other hand a manufacturing powerhouse such as germany would have suffered regardless of the robustness of its internal economy because it has a vast number of trade linkages with the rest of the world
