Twelve years ago, the United States was more worried about summer vacation than terrorist attacks. The attacks that occurred on September 11, 2001 are considered the deadliest acts of terrorism on American soil. Although the attacks only took place in three states, they caused an outcry among Americans across the nation. Data showed that gross domestic product (GDP) for the first two quarters of 2011 contracted and so it was initially thought that gross GDP growth would decline significantly after the attacks. Data released in October 2001 showed that GDP had contracted during the 3rd quarter. This has led to claims that “terrorist attacks have pushed a weak economy into a full-blown recession.” This claim was soon disproved after GDP data was released in 2002, showing positive growth (2.7% annual rate) starting from the 4th quarter of 2001. At the time, due to the attacks, it would have made sense for GDP growth. decrease and therefore this statement seemed plausible. But after reviewing the data, whatever effect the attacks may have had on the economy, they did not push "a weak economy over the edge into full-blown recession." Although the September 11 attacks did not have as substantial an effect on the economy as most people think, they left wounds in the economy that have been trying to heal ever since. The fiscal-monetary response after the attacks was effective in calming anxious citizens. Unfortunately, national productivity took a sharp turn and decreased compared to the previous year, but increased in the following year. Oil prices rose sharply as supplies ran out, but a significant drop in prices followed soon after the chaos subsided. The value of... half the paper... trust in the banking system. Banks borrowed extensively from the Federal Reserve's discount window to make unsettled payments. Major banks in the affected areas have not been affected as deeply because most of them keep their assets and liabilities in other locations and have reserve books. Some foreign banks have suspended their operations in the United States, but do not appear to have suffered major losses. Normal operations resumed within a week of the attacks. Despite harrowing and atrocious attacks on the nation's main financial center during an economic downturn, the economy has shown resilience. This can be attributed to the fact that our economy is one of the strongest in the world, robust enough to withstand virtually any attack. The course of events since 9/11 suggests that policymakers are already adept at responding to crises at the macroeconomic level.
