4) Chinese renminbi
China is transitioning from an export based economy to one that relies on more domestic consumption. Part of this transition will be RMB appreciation as higher domestic purchasing power of imported goods such as food and energy will be needed to increase the wealth of middle income Chinese and get them to spend money on local consumer goods and services. China has stockpiles of foreign reserves and trade surpluses which will also hold up the renminbi as the government has been intervening less to keep the currency down. The renminbi would be rated higher if it was not for strict capital controls.
