An important news about energy market was announced last few days. The US shall supply natural gas to the UK. This is a sign that the US energy independence day is coming. Thanks to fracking and horizontal drilling.
Crude oil import accounts for a huge portion of the US trade deficit. If the US really achieves energy independence, the US trade deficit will shrink hugely. The strong US Dollar era may come.
The implication to other currencies and economy is negative. The same thing happened, widely known as Asian Financial Turmoil, in 1995-1999 to Asia after the rally of the US Dollar.
This is also bad to all commodities as commodities are denominated in US Dollar.
