Please Explain...

This is the sub-headline for a story on the Sydney Morning Herald website this evening...

Dollar fell to an 18-month low against the US dollar, with worries about an impending financial crisis in Turkey

I really don't understand how a crisis in Turkey, affects our dollar's standing against the greenback - & this doesn't help:- "It's a stark reminder that the Australian dollar enjoys the status as the market's preferred risk proxy," National Australia Bank's head of foreign exchange said.

I thought it was our money, not a risk proxy... What even is a risk proxy anyway??!! Sounds like something in a paramilitary operation...

And furthermore:- While the path from a crisis in Turkey to selling the Australian dollar "is a pretty long bow", it was the Australian dollar's superior liquidity that made it such a magnet for traders trying to de-risk in nervous times

Superior liquidity??!! Our dollar isn't even made of paper - it's been a coin since the early 1980s. How is it better able to liquefy than the US dollar? Also... de-risk??!!?? I'm not even sure that's a Turkish word, let alone an English one

But wait... As usual, it appears to be the Donald's fault... Skittish investors sent the Turkish lira to a record low against the US dollar on Friday after US President Donald Trump reportedly said he had authorised higher tariffs on imports from Turkey in response to the sliding Turkish currency

I will never understand the global economy.... Does anyone, really?
