China's yuan devaluation could hurt Apple sales, boost supplier profits, analysts say

Sales of Apple products are likely to be hit at first because of weaker consumer demand, and then possibly by Apple deciding to raise prices if another yuan adjustment takes place, Fubon analyst Arthur Liao told the Wall Street Journal.

The iPhone is already an expensive product in China. An unlocked, 16-gigabyte iPhone 6 is priced at RMB 5288 ($836), or $187 more than the same hardware in America. Further devaluation could prompt Apple to hike prices to maintain profits, but potentially at the expense of selling fewer units.

Apple's suppliers stand to benefit though, assuming revenue doesn't change and the perks aren't passed along to Apple, Sanford C. Bernstein analyst Alberto Moel explained to Bloomberg.

Companies like Foxconn pay their workers and local suppliers in yuan, but much of their income is in U.S. dollars. Moel estimated that Foxconn's gross margins could rise by half a percentage point.

"A yuan cut is going to soften the impact of Apple's weak outlook because if there's no room to boost top line, then at least the currency change can help their bottom line," the analyst added.

China is Apple's next-most important market after the U.S. — during the June quarter, regional revenue was up 112 percent year-over-year to over $13.2 billion. Global iPhone sales did not meet high analyst expectations though, and iPad sales continued to decline. Any setbacks in China could further harm Apple's forecasts.
