It’s one of those useless explanations that while technically true tells us nothing of value about the situation. The Chinese are never boring when coming back from a Golden Week holiday. This weekend was no exception, China’s reopening bringing with it the news of yet another cut in that country’s bank reserve requirement ratio (RRR).

Following two already, one for 100 bps in April and another for 50 bps in July, the PBOC will reduce the RRR for a third time this time for an additional 100 bps. Commentary gives us nothing of use, blah blah stimulus:

Beijing has stepped up liquidity support across the financial system this year as policymakers have focused on calming fears of capital outflows and sought to soothe battered markets even as anxiety grows that a heated trade war with the United States could deal a damaging blow to the broader economy.

China’s yuan currency has faced strong selling pressure this year, losing over 8 percent between March and August at the height of market worries, though it has since cut losses as authorities stepped up support.

These things are all related, not that you would know it. Authorities who “stepped up support” for CNY since August already proposed the basis for the RRR decision. This is all about eurodollar, not Trump’s trade war.

In other words, “stepped up support” for currency means reducing the reserve assets on the PBOC’s balance sheet (or, if you like, selling UST’s). Simple accounting requires either the PBOC to offset those losses with RMB program lending (which tends to be CNY negative) or to further shrink its liability side to match. Guess which one the central bank has chosen the past two years.

The RRR cut signals that the reserve problem, therefore, dollar problem is anticipated to grow worse. The PBOC is actually telling us that they expect in the months ahead the same or perhaps bigger commitment to “stepped up support.” CNY doesn’t need support if there is no worsening “capital outflow” situation of retreating eurodollar funding.
