Whenever there has been a world crisis, it has been typical for foreigners to seek the safety of the US dollar. A common means to accomplish that has been to buy US Treasury debt. The typical example over the past couple of years is that the demand for US Treasury debt has increased at the various peaks of crises among the European Union nations such as Greece, Ireland, Spain, Portugal, and the like.
As a result of these surges in demand, the US Dollar Index, which reflects the value of the dollar against other currencies, tends to increase.
The British Pound has risen almost 15% against the Dollar over the last twelve months. It seems that the markets are ignoring the fiscal concerns that sent the Pound tumbling in 2010, and focusing more on inflation and the prospect of interest rate hikes. At this point, the Bank of England (BOE) is now racing with the European Central Bank (ECB) to be the first “G4″ Central Bank to hike rates.
