28/12/18: BTCD is neither a hedge nor a safe haven for stocks


A quick - and dirty - run through the argument that Bitcoin serves as a hedge or a safe haven for stocks. This argument has been popular in cryptocurrencies analytical circles of recent, and is extensively covered in the research literature, when it comes to 2014-2017 dynamics, but not so much for 2018 or even more recent period dynamics.

First, simple definitions:

  1. A financial instrument X is a hedge for a financial instrument Y, if - on average, over time - significant declines in the value of Y are associated with lower declines (weak hedge) or increases (strong hedge) in the value of X.
  2. A financial instrument X is a safe haven for a financial instrument Y, if at the times of significant short-term drop in the value of Y, instrument X posts increases (strong safe haven) or shallower decreases (weak safe haven) in its own value.
So here are two charts for Safe Haven argument:


The first chart shows that over the last 12 months, there were 3 episodes when - over time, on average, based on daily prices, stocks acted as a strong hedge for BTCUSD. There are zero periods when BTCUSD acted as a hedge for stocks. The second chart shows that within the last month, based on 30 minutes intervals data (higher frequency data, not exactly suitable for hedge testing), BTCUSD did manage to act as a hedge for stocks in two periods. However, taken across both periods, overall, BTCUSD only acted as a weak hedge.

The key to the above is,  however, the time frame and the data frequency. A hedge is a longer-term, averages-defined relationship. Not an actively traded strategy. And this means that the first chart is more reflective of true hedging relationship than the later one. Still, even if we severely stretch the definition of a hedge, we are still left with two instances when the BTCUSD acts as a hedge for DJIA against two instances when DJIA acts as a hedge for BTCUSD.

People commonly confuse both hedging and safe haven as being defined by the negative symmetric correlation between assets X and Y, but in reality, both concepts are defined by the directional correlation: when X is falling, correlation myst be negative with Y, and when Y is falling, correlation must be negative with X. The downside episodes are what matters, not any volatility.

Now, to safe haven:

Again, it appears that stocks offer a safe haven against BTCUSD (6 occasions in the last 12 months) more often than BTCUSD offers a safe haven against stocks (2 occasions).  Worse, the cost of holding BTCUSD long as a safe haven for stocks is staggeringly high: some 60-65 percentage points over 12 months, not counting the cost of trading.

In simple terms, BTCUSD is worse than useless as either a hedge or a safe haven against the adverse movements in stocks.

20/7/17: U.S. Institutions: the Less Liberal, the More Trusted


In my recent working paper (see http://trueeconomics.blogspot.com/2017/06/27617-millennials-support-for-liberal.html) I presented some evidence of a glacial demographically-aligned shift in the Western (and U.S.) public views of liberal democratic values. Now, another small brick of evidence to add to the roster:
The latest public opinion poll in the U.S. suggests that out of four 'net positively-viewed' institutions of the society, American's prefer coercive and non-democratic (in terms of internal governance - hierarchical and command-based) institutions most: the U.S. Military and the FBI. as well as the U.S. Federal Reserve. Note: the four are U.S. military, the FBI and the Supreme Court and the Fed are all institutions that are not open to influence from external debates and are driven by command-enforcement systems of decision making and/or implementation. Whilst they serve democratic system of the U.S. institutions, they are  subject to severely restricted extent of liberal checks and balances.

Beyond this, considering net-disfavoured institutions, executive powers (less liberty-based) of the White House are less intensively disliked compared to more liberty-based Congress.

27/6/17: Millennials’ Support for Liberal Democracy is Failing


New paper is now available at SSRN: "Millennials’ Support for Liberal Democracy is Failing. An Investor Perspective" (June 27, 2017): https://papers.ssrn.com/sol3/papers.cfm?abstract_id=2993535.


Recent evidence shows a worrying trend of declining popular support for the traditional liberal democracy across a range of Western societies. This decline is more pronounced for the younger cohorts of voters. The prevalent theories in political science link this phenomena to a rise in volatility of political and electoral outcomes either induced by the challenges from outside (e.g. Russia and China) or as the result of the aftermath of the recent crises. These views miss a major point: the key drivers for the younger generations’ skepticism toward the liberal democratic values are domestic intergenerational political and socio-economic imbalances that engender the environment of deep (Knightian-like) uncertainty. This distinction – between volatility/risk framework and the deep uncertainty is non-trivial for two reasons: (1) policy and institutional responses to volatility/risk are inconsistent with those necessary to address rising deep uncertainty and may even exacerbate the negative fallout from the ongoing pressures on liberal democratic institutions; and (2) investors cannot rely on traditional risk management approaches to mitigate the effects of deep uncertainty. The risk/volatility framework view of the current political trends can result in amplification of the potential systemic shocks to the markets and to investors through both of these factors simultaneously. Despite touching on a much broader set of issues, this note concludes with a focus on investment strategy that can mitigate the rise of deep political uncertainty for investors.

9/11/16: Bitcoin vs Ether: MIIS Students Case Study


Following last night's election results, Bitcoin rose sharply in value, in line with gold, while other digital currencies largely failed to provide a safe haven against the extreme spike in markets volatility.

In a recent project, our students @MIIS have looked at the relative valuation of Bitcoin and Ether (cryptocurrency backing Ethereum blockchain platform) highlighting

  1. Fundamental supply and demand drivers for both currencies; and
  2. Assessing both currencies in terms of their hedging and safe haven properties
The conclusion of the case study was squarely in line with Bitcoin and Ether behaviour observed today: Bitcoin outperforms Ether as both a hedge and a safe haven, and has stronger risk-adjusted returns potential over the next 5 years.
