Recalling July Asian Dollar

The overnight rate in offshore renminbi liquidity surged over 4% today, the fifth such notable heave in this half of 2015. The rate had been under 2% for the six trading days before and including Friday, but overnight CNH HIBOR jumped from 1.7325% to 4.4525% over the weekend. The one-week maturity similarly spiked, moving from 2.796% at the end of last week to 4.3705% to start this one. Even the 3-month CNH rate, which is typically far, far more stable, increased by more than 60 bps to 4.257%.

Such dramatic moves have become more commonplace in Hong Kong trading of late, coinciding with the obvious travails of eurodollar function especially going back to the start of Q3 (July 6). In more recent weeks, there had been an acute correlation between offshore CNH liquidity and the “price” of “dollar” liquidity in China, as represented by the CNY/USD exchange rate. The PBOC had been involved in pushing that rate upward especially at the end of October after its rate cuts and reserve “release”, but the Chinese central bank has clearly relented on that count. After increasing the country’s official “middle rate” exchange (where the RMB band is anchored), the PBOC has allowed the middle rate to decline for nine straight days including today.
