One way or another: China's yuan policy tweak a warning shot in old battle


By and Marius Zaharia

SHANGHAI/(Reuters) - China's adjustment to the way it sets the reference rate for its tightly managed currency, suspending a tool for fine-tuning the exchange rate, is a fresh warning to would-be speculators that gives the scope to retreat after a year of heady gains.

The decision by the central to reduce the effect of a so-called "counter-cyclical" factor, introduced in May to limit market volatility in the yuan's calculation, initially knocked the currency lower when it was reported on Tuesday.

The move makes the more open to market forces, which could add downward pressure on the currency in the near-term, a help for the country's export competitiveness.

But while it sends a message to a market with a penchant for betting on currency momentum in one direction or another, analysts say it's unlikely to be the silver bullet needs to eliminate wild swings.

More tinkering is likely ahead as policymakers look to reduce volatility on either side of the 6.5 to the dollar mark, seen in recent months as a critical level for regulators.

"Whenever there's a one-way trade and one-way expectation, they tend to do something," said Zhou Hao, senior emerging at "If you don't defend this (6.5 yuan) level, maybe the currency sees another leg of rapid appreciation."

The yuan's past tendency to be pushed one way or another by surges in expectations has long troubled regulators who have sought to liberalise China's foreign exchange market without triggering disruptive capital flight.

In 2016, persistent depreciation expectations drove the down around 6.5 percent against the dollar, prompting a raft of policy measures - including the May 2017 introduction of the secret and discretionary "counter-cyclical factor" - to stop the bleeding.

Last year, though, the currency rebound by around 7 percent as policies bit and sentiment shifted.

Some speculated Tuesday's move was aimed at trade tensions, with annoyed by the dollar's persistent weakness and the yen's decline. To that end, has been diversifying its foreign exchange reserves, and reported on Wednesday that it was considering reducing or halting purchases of U.S. Treasuries. China's forex authority dismissed the report.

For now, the PBOC seems to have drawn a critical line around 6.5 per dollar.

On Tuesday, it effectively neutralised its "counter-cyclical factor", after the had hovered on the strong side of 6.5 per dollar for several days.

When the tested 6.5 in September, the PBOC removed reserve requirements on some contracts to nudge it back to the weaker side of that line.

U.S. policymakers have accused of manipulating the yuan, but on the other side, a source close to China's commerce ministry said Beijing's private frustrations about a weak dollar are growing.

While the was relatively stable throughout October and November, the weak and the Japanese yen's falls against the posed challenges for the yuan's regulators.

"feels that when the dollar falls, the yen does not rise much, which puts big pressures on China," the person said.

"Major central banks have a consensus that competitive devaluation is rule-breaking. But the dollar should appreciate rather than depreciate. Nobody says anything if the U.S. manipulates its currency."

The may not be poised to fall much, though.

"Capital flow dynamics are favouring renminbi strength, not weakness," Chi Lo, at BNP Paribas Asset Management, wrote in a note to clients.

"What is likely to result is higher volatility (two-way trading) for renminbi trading. The outlook for a still balanced flow environment looks likely to continue on the back of moderate GDP growth, improving external environment and improving renminbi sentiment."

Ken Cheung, senior Asian FX at in Hong Kong, said he expected the currency to hover between 6.5 and 6.7 per dollar for at least the first half of the year.

The PBOC declined to confirm the latest change, but said the level of influence of the "counter-cyclical factor" was up to the individual banks that contribute estimates each day for the mid-point calculation. Market participants say the central has always wielded control.

Either way, the "x factor" remains in the PBOC's box of tools, along with others, should the start to move too much in a direction it doesn't like.

"The PBOC will not give up intervention in the FX market. It will continue to seek new measures for currency intervention, either through an adjustment of the 'counter-cyclical factor', or a full revamp of the mid-point formula," said Jianwei Xu, for Greater at in
