Were it not for a 6.6% appreciation of the yuan against the US dollar in the first half of this year (around the same amount of yuan appreciation for the whole of 2007), the carrier would have been deeply in the red at the net level. The yuan’s appreciation delivered China Southern a USD384 million foreign currency gain – more than a doubling of its gain from the same period last year.
China Southern’s total operating revenue rose 9.1%, while yields rose slightly (they should gain more in the second half following a 50% increase in domestic levies from 01-Jul-08) and load factors also improved 1.2 ppts to 73.1%. But fuel costs are surging and China Southern is most exposed to the sharp increases in domestic fuel costs pushed through by the government in late Jun-08.
A big concern is that the recent depreciation of the yuan (that started in Aug-08) becomes entrenched. Much will depend on the strength of the underlying Chinese economy. If growth does falter and the yuan continues to sink, the last pillar of support for airline earnings in China will fall.

The outlook for air travel demand is the other big question. Passenger numbers rose 5.7% in the first half, but growth has been negative since May-08.

Chinese airlines are pinning their hopes on a post-Olympics up-tick in traffic as security measures ease.
If a reinvigoration of demand fails to eventuate, policy makers in Beijing will need to take some urgent steps to support the sector. Whether that involves more cash for the struggling airlines (as suggested by China Southern), another round of consolidation, or the opening of the sector to greater foreign investment – or some combination – remains to be seen. Overall, the second half of 2008 will be pivotal in determining how long the “period of hardship” in Chinese aviation will run.
In the meantime, China Southern stated it would continue to redeploy capacity away from weak markets and seek to raise more revenue from premium cabins to boost its performance, although the slowing global economy could make this task challenging.
