Quote:You might recall that on Monday evening, in a post for this platform, I noted that coming out of options expiration, the "gamma pin" lost quite a bit of its influence. In other words, option hedging was no longer likely to keep things "calm." When dealers' gamma profile flipped negative, it meant that, instead of mechanically insulating the market from large moves, dealer hedging would instead entail market makers selling into a falling market, potentially magnifying the swings. Well, guess what? According to Kolanovic's estimates, dealer hedging accounted for between $40 billion and $50 billion in selling pressure this week. And then there's CTAs, which likely de-leveraged to the tune of $40 billion to $60 billion on JPMorgan's estimates.

As large and positive aggregate gamma impacts the realized volatility directly (dealer need to buy when the spot falls and sell when the spot rises, thereby dampening the potential spot moves on either side), persistence of long gamma positioning can lead to low volatility over extended periods of time. As per our estimates, aggregate gamma on the S&P 500 was positive for more than three-fourths of 2019, and hence we believe this to be a significant cause of lower than expected volatility last year. Heavy gamma positioning was also among the main reasons why the S&P 500 escaped any drawdowns amidst all the US-Iran news flow in the first week of 2020.
Following the large expiries late last week (VIX last Wednesday, everything else last Friday), two macro shock catalysts created a profoundly negative price impulse which sent spot levels in equities index, equities vol. and rates deeply through prior ranges,
which drove dealers into short gamma territory, meaning that instead of insulating market moves as they had been previously, dealer hedging flows would see them pressing into the directional moves [which in this case] meant shorting into the new lows in equities, buying VIX and buying USTs/STIRs the more they rallied.

Quote:The Tom Tom Traffic Index, run by the same company you once used to get around before smartphones, uses the data from its 600m drivers to gauge the level of congestion in 416 major cities worldwide. Handily, the index covers some of the major Chinese cities, so let’s take a quick look at the data. As a quick note, a 23 per cent congestion level means a journey takes 23 per cent longer than it should with no traffic. You see that small spike this Monday morning? Traffic levels actually bounced to 66 per cent, encouragingly 3 percentage points higher than in 2019. Evening congestion, however, is less intense at just 29 per cent, versus a 56 per cent average. Not everyone is convinced by the traffic data, however. The Economist’s Simon Rabinovitch, who is based in Shanghai, thinks the main reason is because those returning to work are still worried about taking public transport

And some awkward dilemma's:
Quote:Although the economy will need some sort of stimulus if it falls into a recession, I am not sure this is the time for it. There are many reasons for taking this point of view.
1. Providing incentives to boost economic activity from the natural rate dictated by the existential threat we face is bad health policy. One could easily see a strong correlation between economic activity and the spread of the coronavirus. Think of the marginal worker receiving extra pay to get on public transport to come to work, whereas he or she might otherwise stay at home. We should instead focus everyone's minds, including those obsessed by fortunes available on Wall Street, if they are able to distract themselves, to stopping the virus and let that dictate our economic activity, however dire the economic outcome. Reducing economic activity temporarily might help to reduce the spread of the virus.
2. If we are then successful at facing off this threat and containing it, only then should the relatively bare cupboard which contains the central banker's remaining toolkit be opened to deal with a recession. Using the tools now means, if worse is to come, the central banks will have even less firepower when they need it most.
3. We should be prepared to suffer a recession and declining living standards for a short period than have 1/2 the world infected. For an economic policy standpoint, the latter would in any case result in a far worse economic outcome.
