2011 Sendai Earthquake And Tsunami, Tōhoku Region, Pacific Ocean

Economic analysts posit that, ultimately, the catastrophe will improve Japan's economy, with increased job availability during restoration efforts. An analyst at JPMorgan Chase, citing the 1989 San Francisco earthquake and the 1994 Northridge earthquake, noted that natural disasters "do eventually boost output." An analyst at Société Générale anticipated that Japan's economy will decline in March but will revive powerfully in subsequent months. After the Kobe earthquake, industrial output dropped 2.6%, but increased by 2.2% the next month, and 1% the following month. Japan's economy then accelerated substantially through the next two years, at more than its former rate. There are others who posit that this is harmful to the economy, and that the above analysts are falling prey to the broken window fallacy.
Global financial impact
In the immediate aftermath of the earthquake, Japan’s Nikkei stock market index saw its futures slide 5% in after-market trading. The Bank of Japan said that they would do their utmost to ensure financial market stability.
