Explainer-What’s inside China’s toolbox to rein in excess yuan

SHANGHAI (Reuters) – is facing renewed downward pressure, dragged lower by a surging U.S. dollar, a hawkish Federal Reserve and widening monetary policy divergence between the world’s two largest economies.

The yuan has lost about 4% to the dollar since mid-August to weaken past the psychologically important 7 per dollar level. The local currency also looks set for the biggest annual loss since 1994, when China unified official and market exchange rates.

The rapid yuan declines prompted the People’s Bank of China (PBOC) to lower the amount of foreign exchange financial institutions must hold as reserves to rein in weakness.

WHAT ELSE HAS PBOC DONE SO FAR TO SLOW THE YUAN’S DECLINE?

The PBOC has been setting firmer-than-expected daily yuan midpoint fixings since late August to prevent excess yuan weakness, as the onshore spot yuan can only trade in a 2% narrow range around the midpoint.

Market participants take any significant discrepancy between market projections of what the fix might be and where the PBOC actually sets it as an indication of which way the central bank wants to tug the market.

Senior officials from the central bank and FX regulator have also ramped up efforts warning the market of strong one-way bets against the local currency through verbal messages.

Wang Chunying, spokesperson of the State Administration of Foreign Exchange (SAFE), was quoted by the state broadcaster CCTV last week urging companies not to speculate on the currency.

WHAT OTHER OPTIONS DOES PBOC HAVE, OTHER THAN OUTRIGHT INTERVENTION?

** HIGHER TRADING COST

The PBOC could make it more expensive for financial institutions to short the yuan in derivatives markets, by raising their foreign exchange risk reserve ratio when purchasing dollars through forwards.

The central bank has adjusted the risk reserve requirements multiple times over the past few years before it scrapped it in October 2020, when the yuan rose sharply.

** TIGHTER OFFSHORE LIQUIDITY

The central bank could issue yuan-denominated bills in Hong Kong to withdraw yuan from the offshore market and raise the cost of betting against the Chinese unit.

“The Chinese authorities are leaving no doubt about their resolve to dampen depreciation pressure on the yuan,” said Khoon Goh, head of Asia research at ANZ.

“If depreciation pressure remains, the PBOC could raise the reserve requirement for forwards to 20%, or increase yuan bill issuance in Hong Kong to make it more expensive to short the .”

** COUNTER-CYCLICAL FACTOR IN YUAN’S DAILY GUIDANCE FIX

The PBOC first introduced the counter-cyclical factor to its daily midpoint fixing formula for the yuan-dollar exchange rate in 2017.

The regulators said the factor was an effort to better reflect market supply and demand, lessen possible “herd effects” in the market and help the market focus more on…
