Learning lessons from the value of the silver denarius
History shows that assuming intrinsic value can be naive and expensive
A sensible and historically successful approach to investing begins with the belief that every asset has an intrinsic value. Before investing in an asset, the challenge is to apply some valuation or series of valuation approaches, to estimating its intrinsic value. Only then can a decision be made as to whether this value is sufficiently attractive relative to its market price to warrant an investment.
In the words of the most successful practitioner of such an approach, Warren Buffett, to the shareholders of his company Berkshire Hathaway in 1999: “Intrinsic value can be defined simply: it is the discounted value of the cash that can be taken out of a business during its remaining life.”
A crucial implicit assumption however is that both the intrinsic value and the market price of the asset are denoted in something which itself will retain value.
Whether this is a psychological attachment to some half- remembered ‘gold standard’ or a questionable belief in the commitment of some ‘sovereign’ to ‘sound money’, this assumption of a stable unit of account and store of value, ie, of stable money is one that deserves more attention.
Briefly considering history suggests that assuming a sustainable anchor or intrinsic value has been both naive and expensive. While there may be no definitive or catch-all solution to this problem, in this era of unconventional monetary experiment I think giving it a little more thought is timely.
The fall of the Roman Empire in 476AD is one of the most widely debated events in history. Among a myriad of contributing causes, the progressive debasement of the coinage and the eventual collapse of the money economy arguably played a central role in plunging much of Europe into the Dark Ages.
The purity and weight – ie, the intrinsic value of the silver denarius – had been sacrosanct to Romans for centuries. As a unit of account, a means of exchange and a store of value, it is credited by many with playing a key role in the monetary stability and economic success of the greatest Empire the world had ever known.
This began to change in 64AD following the great fire which destroyed much of the eternal city.
Rather than raise taxes to fund the massive re-building work, the Emperor Nero chose to scale back the purity and weight of the silver denarius. The long journey of progressive debasement had begun.
By 270AD the silver denarius had been debased to the point that it contained just 0.02 per cent of silver; it had been debased to just 0.02 per cent of its intrinsic value. This progressive undermining of the value of the coinage produced a progressive decline in its purchasing power.
