A Bloomberg piece argues that Aussie assets, and in turn the AUD will suffer in the wake of the yuan SDR inclusion

Credit Suisse Group AG, BNP Paribas SA and Mizuho Bank Ltd are all cited

The IMF's decision "could have more impact on those currencies acting as a renminbi proxy, such as the Australian dollar"

While the Aussie isn't in the SDR basket, reserve managers bought the nation's government debt in the years after the global financial crisis as a higher-yield bet on economic growth in Asia. Investors were also drawn to Australia's top sovereign rating and its liquid currency.

Premier Li Keqiang's moves to ease capital controls have bolstered the case for investors to seek higher returns in yuan bonds. Australia's benchmark 10-year government bond yield rose about 17 basis points this year to 2.91 percent, still less than China's 3.14 percent.

Huh ...

Maybe there will be some impact ... and maybe its weighing on the AUD. More at Bloomberg.
