CNY Fix and SHIBOR Suggest PMI Results Only Half The Story

There does seem to be internal financing adjustments going on inside the arcane and cumbersome framework of USD/CNY. Whether or not that is desirable remains to be seen, but the case of the past few weeks suggests, and somewhat strongly, that the PBOC is again losing control. What it is almost certainly like is trying to squeeze a balloon: every time the Chinese central bank aims and endeavors to stamp out volatility in one factor it only shows up in another.

That was the setup for the global August liquidations, as the PBOC was impressing the entire exchange rate CNY in increasing intensity for five months March to August. Through that period, it is not surprising to find it was then that Chinese stocks collapsed. The steadily rising SHIBOR rate (Shanghai Inter Bank Offered Rate), in the shortest terms, told of the internal illiquidity struggle even though the PBOC was desperately trying to mask the related tendency of CNY (and CNH) to “devalue”; which is just a more troublesome and expensive “dollar” problem. That it would lead to so much havoc in mid-August explains the attempt as a means to suppress a very intense and acute imbalance that was developing, with the PBOC somewhat understandable in its orthodox instincts (to override “markets”).

Since then, the PBOC has shifted its focus to internal mechanics and only intermittently against CNY. O/N SHIBOR has now been suppressed while the PBOC relents upon the currency fix where it can no longer hold it something like stable. In other words, the “cost” of fixing CNY appears to be internal liquidity through SHIBOR, whereas the “cost” of holding SHIBOR internally seems to be the CNY (and CNH) fix. As if Werner Heisenberg were running the show in China, the PBOC can only do one or the other.

In more recent weeks, however, there have been suggestions that they can’t do either one all that well. In the week surrounding the FOMC’s rate decision, the huge depreciation in the fix was brought down to less of an intense slope only to see SHIBOR suddenly depart the very narrow range the PBOC was trying so hard to maintain. From mid-November until late December, the middle rate (or PBOC policy reference fix for the band governing US$ exchange) moved down from about 6.35 all the way to 6.46 or 6.47; during that same time, O/N SHIBOR moved in nearly a perfectly straight line, 1.786% in early- and mid-November to 1.788% the day of the FOMC decision.

Through the end of the year, however, the fix stopped moving so far down—only 6.478 on December 23 and 6.4912 New Year’s Eve. Against that, O/N SHIBOR has suddenly restarted, maybe to its prior ascent.
