RBA in numbers

Interesting data out via a Bloomberg FOI request (via FT Alphaville).  Some detail of foreign holdings of AUD (in particular central banks) and the way RBA goes about determining the extent of overvaluation.

....The staff's preferred model is based on the long-run relationship between the real exchange rate and the terms of trade and the real policy rate differential with the G3 (US, euro area and Japan) over the post-float period. It suggests the exchange rate is around 5 per cent overvalued.......While the bank has signalled that the dollar has been a factor in deciding recent rate cuts, and there's been a bit of 'passive intervention' with a chunk of foreign currency, so far it does not seem to have done much....

...We have to wonder how much of the central bank's low-key response to the AUD's overvaluation is because officials genuinely think the Australian economy can cope, and how much of it is because doing anything about it is too damn difficult. The RBA is already in a cutting cycle but slashing rates very low would risk inflation. Going Swiss is not an attractive option for small economies that have inflationary pressures; as the New Zealand central bank governor outlined last week....(here)

Fair enough but what is likely disturbing is that there are well a couple of assumptions in play, particularly that i) the high AUD hasn't had an impact yet (arguably it has) and ii) the RBA still has control of its currency

...In that scenario, how long might it take before even a 'moderately' overvalued currency takes its toll? We also can't help noting that the central bank of New Zealand, a much smaller economy in a very similar predicament, has decided that despite the risks it is time to go a little harder by explicitly threatening intervention .... RBA governor Glenn Stevens says that if things get really bad, a strong Australian dollar probably would cease being a problem....

What if the AUD doesn't fall or falls very abruptly?  There is a currency war after all. And in case you are wondering whether imports (including outward tourism) are on expanding too rapidly, symptomatic of an overvalued currency, then read this.

AUD is not a reserve currency...

An interesting side issue from the currency war debate.  In talking up the likely devaluation of the Aussie dollar, Debelle mentioned its widespread holdings among central banks.  It is true that hot money, including from central banks has been attracted to Australian bonds, with Australia seen as a relative safe haven, having high interest rates and good metrics.  

First thing to note is that metrics are degrading.  Swan's budget is sinking into deficit like a dead dodo (estimates are sinking to $15 billion here).  This means less incentive to hold Aussie dollar bonds.

But more significantly, Australia is a very small economy.  The argument made previously for not intervening is that Australia's debt markets and central bank are too small to counteract global flows.  Overall, thanks to mining plays, Australia's dollar has the character of an emerging market currency, once hot and decoupled from atlantic turmoil, now facing outflows.

Unlike China, which cannot sell parts of its massive holding of treasuries for fear of wiping out its remaining holdings, there is no reason why all those central banks Debelle is talking about will feel inclined to keep their Aussie bonds.  Debelle said:

....There's no limit on our ability to supply Australian dollars...we have more Australian dollars than anyone else in the world because we print them," he added, pointing out that Switzerland had successfully capped the value of the Swiss franc against the euro since 2011....(here)

Firstly there is no comparison between Switerland and Australia in terms of the size of their fx markets or Switzerland's proximity to the Eurozone.  Secondly and more importantly, who will even want Aussie dollars in months and year's time?
