Asian superpower China is struggling to win the race to maintain a constant fall of the Yuan as investors pile up bearish bets against the currency outside the country.

Recently the opening between the Yuan’s worth against the dollar in the local market and in the offshore market in Hong Kong, has been widening. This spread touched 0.0333, its widest since the beginning of October, though it narrowed a touch on Thursday.

Even the Chinese establishments firmly limit the way the Yuan trades at home, it can be traded much easily in Hong Kong. However its value against the US currency is usually about the same in both markets.

This increase in gap is somewhat making it difficult for the central bank, especially for an approach of letting some air out of the currency at a space Beijing dictates. Both Yuan markets at home and in Hong Kong regularly feed off each other. Furthermore, a weaker Yuan offshore could hearten more Chinese businesses and individuals, the backbone of the central market to seek out to translate their currency into dollars, hypothetically adding descending pressure on the nationally traded Yuan.

In the meantime, China had to face a weaker Yuan since early October, just after its entry into the International Monetary Fund’s elite group of reserve currencies, admitting that a cheaper currency is the price of using easy money to hold up the economy.

The speed of reduction has accelerated since Donald Trump’s surprise U.S. presidential-election win sent the greenback mounting and emerging-market currencies plummeting. This year yuan fell 6.2% against the American currency in onshore markets, getting to 6.9152 against the dollar in the recent close, with above third of the drop in the past two weeks.
