The upbeat mood among equity investors in the United States as well as Europe helped steady markets in China after the sharp plunge in the yuan and talk of credit tightening had seen stocks in Beijing suffer their biggest drop since September.
Spot yuan has entered a dramatic weakening cycle in recent weeks, guided by a series of moves by the central bank, with the unwinding of yuan positions by banks and funds adding downward momentum.
China allows the yuan to move 1 per cent above or below a midpoint set daily but traders believe the recent depreciation is intended to set the stage for a widening of that band to 2 per cent or more this year to make it more free moving.
The yuan move has some relation to the slowdown in the Chinese economy but it looks more that it has been orchestrated by the PBOC to make it more of a two-way street for speculators.

MSCI's broadest index of Asia-Pacific shares outside Japan added 0.5 per cent, while Seoul gained 0.7 per cent. Australia's market briefly hit its highest since mid-2008 on a run of solid earnings reports.
