Yuan in Freefall: PBOC Intervenes as Trump Tariffs Trigger 2% Currency Plunge

The Chinese yuan suffered its sharpest one-day decline in three years Thursday, plummeting 2% against the U.S. dollar as markets reacted to President Trump’s proposed 50% tariffs on Chinese goods. The dramatic move forced the People’s Bank of China (PBOC) to take emergency stabilization measures.

PBOC’s Defense Playbook:

  • Dollar Sales: Estimated $15B in forex interventions
  • Forward Guidance: Stronger-than-expected daily fix at 7.29
  • State Bank Orders: Major lenders told to limit dollar purchases

Market Mechanics:

  • Offshore yuan (CNH) volatility spikes to 11.2 (highest since 2020)
  • 1-month risk reversals show traders pricing in further 3% drop
  • Yuan funding rates in Hong Kong’s offshore market (CNH) exploded to 5.8% 

“This is currency war brinkmanship,” said Standard Chartered’s Eddie Cheung. “China appears willing to tolerate depreciation up to 7.50, which would effectively offset Trump’s tariffs.”

Global Spillover:

  • EM Currencies: Indonesian rupiah hits 4-year low
  • Commodities: Copper prices drop 3% on China demand fears
  • Debt Markets: Dollar bond yields for Chinese developers spike 200bps

Analysts warn sustained yuan weakness could:

  • Trigger competitive devaluations across Asia
  • Force the Fed to delay rate cuts
  • Accelerate capital outflows from emerging markets
