Glenn Stevens is perhaps best known for his softly spoken manner in a business where understatement can sometimes be the name of a high stakes guessing game.
The outgoing RBA governor's carefully constructed sentences are more often than not punctuated by elongated pauses where silence and thinking time underscores the power of almost every every word.
Aware that his utterances can move markets, Mr Stevens is not surprisingly conservative in his communications.
At times though he has ventured away from his world where the sound of economic jargon resonates at RBA headquarters in Sydney's Martin Place.
But Mr Stevens has occasionally sidestepped the comfort zone of jargon with unexepected straight talk that has taken central bank observers and this reporter by surprise given that we spend so much time deciphering for the general public.
Late last year, Mr Stevens famously told market players to "chill out" as he attempted to derail constant suggestions that the Reserve Bank was poised to cut interest rates as it did on Tuesday.
In February, Mr Stevens was asked for his analysis on global market volaltiity after a series of steep falls in China looked like heralding a wider meltdown.
The governor's explanation to a parliamentary economics committee that financial markets were "dropping their bundle" made news because of the unusual bluntness and the lack of any economic reasoning.

But bluntness doesn't always work.
Mr Steven's attempt at dry humour (or calculated jawboning) backfired in July 2013 when Mr Stevens wryly noted that the RBA board had deliberated for "a very long time" before leaving the cash rate on hold.
Wire services did not detect a possibly raised eyebrow or nod and a wink and as a result the market interpreted the comment as a sign that rates went very close to being cut.
The dollar plunged below 91 US cents which in hindsight could be interpreted as stroke of accidential brilliance given the damage the high dollar was doing to the economy at the time.
So while Glenn Stevens' legacy will be framed around his handling on the global financial crisis in the wake of the 2008 Lehman Brothers collapse, he will be remembered for shaking up communications policy at the ultra conservative central bank.
Just over a year into his appointment as RBA governor, Mr Stevens announced "new arrangements" for the communication of the closely watched and market moving decisions on interest rates.
Before December 2007, the Reserve Bank only issued a written explanation of its decision if rates were raised or lowered and there was no commentary if rates were left on hold.
The additional information on all decisions gave economists and reporters a greater insight into the machinations inside the RBA boardroom and the opportunity to compare subtle changes in words or phrases on the board's general thinking.

At the time, a few interest rate strategists quipped and almost complained that the extra information could put them out of business.
In what was seen at the time as an explosion of information, the RBA also announced it would publish the minutes of the monetary policy meeting two weeks after the decision bringing the RBA into line with other major central banks like the US Federal Reserve and the Bank of England.
The RBA also released its rates policy statement at 2.30pm AEST on the first Tuesday of the month (except January) rather than at 9.30am before the stock market opened.
Glenn Stevens also used his dry tones in 2010 to warn of the potential risks of a real estate bubble in Sydney and Melbourne, warning on breakfast television that investors should not expect prices to keep rising forever.
Mr Stevens surprised journalists by appearing on Channel Seven's Sunrise program describing himself as a "boring bloke" and warning regular people that investing in bricks and mortar was not a path to assured propserity.
Listen to my report from March 2010
With five months to go in the job, Mr Stevens is still dealing with concerns about rapidly rising real estate prices.
And by cutting rates to 1.75 percent on Tuesday he took a calculated risk that more investors will not be tempted to pile into low rate loans that will inevitably rise.
Glenn Stevens might be an unwitting communications supremo but as his days as RBA boss are numbered reporters like this central bank watcher will be queueing up to get his final word on where Australia and the world are heading.
