Nearly $40 billion a year piles into the Philippines, thanks to work its citizens do abroad or for outsourcing firms, but the windfall also brings pain through an overvalued currency and the risk of catching the "Dutch disease."
Economists gave that name to an ailment which hit the Netherlands long ago after it discovered large gas reserves, which spurred big cash inflows. These made the guilder strengthen so much that Dutch-made products became uncompetitive, and the country's manufacturing exports plummeted.
In the Philippines, inflows from outsourcing contracts and millions of citizens working overseas lift incomes yet also have made the peso appreciate sharply, to the point where Barclays reckons it is the most overvalued of the world's widely traded currencies.
A strong currency could derail expansion for Philippine manufacturers. The sector, disappointing for decades, grew 8.1 percent last year, and the Philippines - despite poor infrastructure and rolling power-cuts - seems well placed to grab some production leaving China because of rising costs.
