Until now, perhaps the most intriguing question concerning the Chancellor, Philip Hammond, hasn't centred on his economic approach - but whether or not he was once a goth. Former schoolmate Richard Madeley (yes, he of This Morning fame) claims he resembled "Johnny Depp in his pomp" complete with shoulder-length raven locks and a leather trench coat, as evidenced by his class photos. The man in Number 11 laughed off the "shocking" allegations, saying goths "hadn't even been invented in those days."
Whether or not Mr Hammond was actually a trendsetter back then, the "fiscal reset" he's unveiling now isn't groundbreaking. He may have shelved his predecessor's target of a surplus by 2020, and found cash for housing and transport projects. But this isn't a Chancellor who's ditching austerity at the first sign of trouble. He admits retaining some kind of framework to eliminate the deficit is essential, not least to maintain credibility with the financial markets. (Ironically, this was also the argument used by George Osborne - yet the UK still lost it's triple "A" rating and despite that, bond yields remain below their levels of five years ago).
On the other hand, the economy is holding up after the "no" vote, so why not just stick with the austerity blueprint? That would be beyond short-sighted. Article 50 and those protracted negotiations are yet to be triggered. To date, firms are at most pressing the "pause" button on hiring or investment, pending the Brexit process. It'll be sometime before we know if both of those, along with trade and consumer spending are going into reverse - or expanding regardless. In short, we ain't seen nothing yet.
Governments and and central banks aren't setting policy for today - their actions take about a year to impact on the real economy. No one knows exactly where these uncharted waters will lead us by then. Already, the most detailed post-Brexit scenarios envisaged pre-23 June - be it from the Treasury or OECD - appear outdated. So while market-watchers might be frustrated by Mr Hammond's refusal to name a new target date for balancing the books, it may be a canny move not to box himself into a corner (remember Mark Carney's dalliance with forward guidance?).
With so many unknowns, pragmatism is perhaps the only realistic option - a sort of austerity-lite. Mr Hammond has hinted that, for now, this may mean a baseline policy of " borrow to invest" - more a leaf out of Mr Brown's book than Mr Osborne's.
But is Brexit forcing this Chancellor into a fiscal reset or enabling a personal belief that austerity was going to far, too fast anyway? That is perhaps is now the most pertinent question (along with whether or not that leather trench coat is still hanging in a wardrobe in No. 11).
