Japan's economic outlook following the 11 March 2011 Earthquake


21/04/2011 - The 11 March 2011 Great East Japan Earthquake was the strongest ever recorded in Japan and triggered the country’s worst disaster of the post-war era. The earthquake and accompanying tsunami resulted in an enormous loss of human life, as well as massive economic damage. A preliminary report by the government estimated the damage to social infrastructure, housing and private firms’ fixed capital at between 3.3% and 5.2% of 2010 GDP.

In addition to the usual risks related to the strength of world trade, exchange rates and commodity prices, there is great uncertainty about developments in Japan, including the duration of electricity shortages, the problems at the Fukushima nuclear plant and the size and timetable of government reconstruction spending. Consequently, the timing and strength of an economic rebound is exceptionally difficult to forecast.

The earthquake hit when Japan’s expansion appeared to be back on track following the economic slowdown in the latter part of 2010. The immediate impact of the horrendous disaster is likely to be large, extending beyond the areas devastated by the earthquake and tsunami. Indeed, damage to factories in the Tohoku region has disrupted the supply chains of key industrial products even beyond Japan, notably in the automobile sector. Consequently, the Bank of Japan’s April report downgraded its assessment of seven of Japan’s nine regional economies. However, the experience of past disasters in Japan and other developed countries suggests that the negative short-term impact on economic output will be followed by a rebound as reconstruction spending picks up. Such a pattern is projected to slow real GDP growth to 0.8% in 2011, followed by a pick-up to 2.3% growth in 2012.


The damage to the capital stock, electricity shortages and the disruption of supply chains is projected to significantly reduce output in the second quarter of 2011 (see chart below), although it is likely to be relatively mild compared to the 20% drop (seasonally-adjusted annual rate) following the 2008 Lehman shock. Output is expected to rebound sharply from the third quarter of 2011, driven by reconstruction-related fixed investment:

  • The downward trend in public investment will be reversed by government reconstruction efforts, which are assumed to amount to 5.6 trillion yen (1.1% of GDP) by the end of 2012. One-half of this spending takes place in CY 2011 (see the box below on the fiscal assumptions).
  • Business investment is expected to increase sharply beginning in the third quarter as firms replace or repair equipment damaged in the earthquake and tsunami.
  • Residential investment also picks up rapidly to rehabilitate or replace the housing damaged or destroyed in the March disaster.   



In contrast to fixed investment, private consumption is projected to remain relatively subdued during 2011, reflecting weaker household confidence, as occurred following the Kobe earthquake, and the impact of measures to finance reconstruction spending without increasing government borrowing. In addition, with electricity shortages likely to continue through the summer, the electric utilities have asked consumers to conserve energy and some stores have shortened their opening hours. Consumers may also scale back conspicuous consumption. As reconstruction spending and residential investment gain momentum, private consumption, particularly for consumer durables, is likely to strengthen in 2012. 

An extended downturn is thus unlikely. On the external side, there have been signs of a pick-up in trade in the Asian region, which accounts for 56% of Japanese exports. In addition, several domestic factors that were apparent in early 2011 prior to the earthquake will continue to have a positive impact on activity. First, the fiscal stimulus packages launched in the autumn of 2010 will support the economy in the first half of 2011. Second, the labour market had improved markedly by early 2011, as shown by the rise in the job-offer-to-applicant ratio from its trough of 0.43 in 2009 to 0.62 in February 2011.


Assumptions underlying the projections

Although the government has yet to announce its reconstruction spending plan, the response to the 1995 Hanshin-Awaji (Kobe) earthquake is taken as a benchmark. Reconstruction spending by the central government amounted to 3.2 trillion yen (0.7% of GDP) in the 15 months following the earthquake, and to 5 trillion yen over a six-year period. Given that the 11 March disaster is estimated to have caused 16 trillion to 25 trillion yen of damage – compared to the 9.6 trillion yen wrought by the Kobe earthquake -- reconstruction spending is assumed to be correspondingly higher at 5.6 trillion yen (1.1% of GDP) through the end of 2012.

OECD projections are based as closely as possible on governments’ announced fiscal policies.  The June 2010 Fiscal Management Strategy’s target of limiting the issuance of new government bonds in FY 2011 to the FY 2010 level of around 44 trillion yen (9% of GDP) is still government policy. Consequently, the additional 5 trillion yen in reconstruction spending during FY 2011 is assumed to be financed by:

  • The reserve fund in the budgets for FY 2010-11 (1.3 trillion yen).
  • Shifting public investment in FY 2011 budget to reconstruction (0.3 trillion yen).
  • Delaying 0.9 trillion yen in spending increases, such as the expansion of the child allowance. 
  • Postponing the planned cut in the corporate income tax rate (0.6 trillion yen).
  • Other measures to increase revenues (1.9 trillion yen).

Other key assumptions underpinning the projection:

  • The Bank of Japan’s policy interest rate is assumed to remain between 0 and 0.1% through 2012.
    The exchange rate is assumed to remain constant at its 18 March 2011 level of 80.95 yen per dollar.
  • The price of oil (Brent crude) is assumed to remain constant at $110 per barrel from the second quarter of 2011.
  • The price of commodities is held constant at its February 2011 level.
