When Elon Musk’s Tesla became the biggest name to reveal it had added bitcoin to its coffers last month, many pundits were swift to call a corporate rush towards the booming cryptocurrency. Yet there’s unlikely to be a concerted crypto charge any time soon, say many finance executives and accountants loath to risk balance sheets and reputations on a highly volatile and unpredictable asset that confounds convention. “When I did my treasury exams, the thing we were told as number one objective is to guarantee security and liquidity of the balance sheet,” said Graham Robinson, a partner in international tax and treasury at PwC and adviser to the UK’s Association for Corporate Treasurers. “That is the fundamental problem with bitcoin, if those are the objectives for treasurers, then breaking them could get them in trouble.” Tesla Inc’s $1.5 billion bitcoin bet saw it join business software firm MicroStrategy Inc and Twitter boss Jack Dorsey’s payments company Square Inc in swapping some traditional cash reserves for the digital coin. Proponents of the cryptocurrency see it as a hedge against inflation at a time of unprecedented government stimulus, a falling dollar and record-low interest rates that make attractive high-yielding assets hard to find.
