The 10 Most Expensive Terrorist Attacks In History

Terrorism leads to high costs in human lives and property. However, it also has significant impacts on the economy of the nation that is at the receiving end of the attacks. Major terrorism attacks can be economically devastating for a country, affect the domestic and even global economy, depending on the nature of the crime and the target nation.

First, there are the direct economic costs of a terrorist act. These include the damages suffered by the victims, the government, the costs of rebuilding, insurance costs, expenses for counter-terrorism measures, victim rehabilitation costs and other expenses that can punch a significant dent in the victimized country's economy.

Then, there may be indirect costs, such as a fall in the value of the dollar and the price of oil for instance. While the pernicious attacks may be brief, the damage can continue to have repercussions for years. The damage suffered by the twin towers of the World Trade Center in the September 11 attacks against the U.S., for instance, triggered the expensive war on Iraq and had other economic consequences.

The September attacks on the WTC sent ripples across the world, leading other nations to increase their security spending. Australia, for instance, went on to increase its homeland security budget and aid to Iraq and Afghanistan. Since 2001, the country has spent a total of $21.3 billion in defense and aid for the Iraq war.

Other indirect costs of the war may include loss of income from a slowing down of tourism. The terror attacks in Mumbai's Taj Palace Hotel in 2008, for example, would have impacted tourism to the city and indirectly affected the economy of India. The UK public transport bombings of 7/7 also led to significant losses in tourism revenue.

There are also the costs of running a terrorist attack, though these are usually far less compared to the damage done. Here we take a look at the 10 Most Expensive Terrorist Attacks in History, based on figures for insured property losses, repair costs and other estimated costs.
