Comment: Why I don’t trust Chinese data on the pig herd rebuild

Andrew Whitelaw, TEM, February 10, 2021

One of the biggest drivers of world meat pricing in the past couple of years has been the impact caused by African Swine Fever on China’s pig herd. Here, Thomas Elder Markets analyst Andrew Whitelaw reflects on the extent of the pig herd recovery in China, and whether local reports about progress are reliable

 

 

 

 

A Chinese herd rebuild is negative for meat pricing. Has it happened?

  • The pig herd in China is rebuilding. The question remains about the efficacy and pace of the rebuild.
  • Chinese government data points towards a swine herd at close to pre-ASF levels.
  • China continues to import large volumes of meat, which would have reduced if the herd was approaching normal levels.
  • The price of pork continues to remain high despite an apparent swine herd rebuild. If supply was available pork prices would be dropping.
  • Recent Chinese government notices raised issues with animal data collection methods.
  • The efficacy of the rebuild is in question, with smaller litter sizes and less productive pigs.
  • Other diseases have been resurgent in the nation.
  • The herd will be rebuilt, but it will take time. When this occurs, we will see an impact on our meat pricing.

An analyst role is to interrogate data and combine it with experience to develop ideas and solutions. It is also essential to question the data. Is it reliable? Is it marrying-up with other datasets or just own experience?

Let’s look at an example we can all relate to. The BOM has told us that it has rained overnight based on data modelling. This may be correct, however you haven’t heard a drop of rain on the roof during the night, and the rain gauge when checked is empty. The data might tell you one thing, but experience tells you another.

So what about the Chinese pig herd?

One of the biggest drivers of meat pricing in the past couple of years has been the impact caused by African Swine Fever (ASF). The outbreak caused the loss of a large proportion of all pigs within the nation.

The protein gap caused by the loss is abut 25 million tonnes during 2020. To fill the pork gap, the Chinese had to import proteins of various kinds in increasing volumes, from sheepmeat to chicken. However, the reality is that there is only a finite volume of meat available for export worldwide and a gap of 17 million tonnes emerged.

So the deficit of protein caused by the outbreak of ASF in China (& others) has caused a knock-on effect on meat values worldwide as China gobbles up supplies.

What goes up, must come down. Demand from China has caused a substantial increase in pricing levels due to a lack of local supply. Therefore, the Chinese swine herd is vital to Australian beef producers, as when it corrects demand for imported protein will drop.

So where is China up to?

According to Chinese government data, the pig herd is making a sustained and fast recovery. There are various estimates for the recovery based on Chinese government data, but it is expected based on their datasets that the outlook is for a swineherd that has been rebuilt to more thsan 80 percent of pre-ASF levels, with a  likelihood of a full rebuild during 2021.

We expect that the rebuild will take a little longer, and closer to current government levels towards the end of 2021. Why do we think that the Chinese government is being optimistic?

The reasons, we believe are fourfold.

Import data doesn’t correspond with an effective rebuild

ASF led to dramatic increases in Chinese imports of proteins. These imports ramped up during the latter half of 2019 into 2020.

However, the reality is that imports of meat have remained at very high levels. In fact, the most recent data (December 2020) shows the second highest import level for all meats.

High import volumes do not point towards a significant increase in pork rebuild to close to pre-ASF levels. If the supply of pork was up, then imports of such volume would not be necessary.

When imports start declining rapidly, then that will point towards an effective rebuild.

The price

The price of a commodity is an easy indicator of all the elements of supply and demand. As in our markets, supply and demand economics is primarily king.

If a price is high, then supply is not keeping up with demand. When the price is low, that is an indicator of supply exceeding demand.

In recent weeks the price of pork in China has been declining, but this may in part be due to the release of frozen pork from state reserves ahead of the Chinese new year. At present, though pork prices are 140pc higher than the same week during 2019.

Some analysts may believe that the higher prices result from higher demand that was growing before ASF. It is far more likely that the higher values are a result of supply not meeting demand.

When pork prices drop considerably, and consistently, then that is a harbinger of an effective herd rebuild.

Chinese statistic-gathering

In a notice posted on the Chinese Ministry of Agriculture website back in September (see here), the Chinese government has itself highlighted that there are issues around gathering statistics on livestock.

The issues include:

  • Lack of responsibility by statisticians.
  • Data confusion
  • Unstable teams
  • Lack of attention to detail
  • Delayed collection
  • Low budget

The above issues don’t bode well for accurate datasets. Suppose the Chinese Ministry of Agriculture holds concerns. Why should we treat the data as gospel, especially when other indicators, such as imports and prices, point to a low supply environment?

It is quality as well as quantity when it comes to a rebuild

There is more to the Chinese pig herd rebuild than just the number of pigs available. Quality is also an element to be taken into account.

The genetics have taken a hit due to the large cull. This has resulted in smaller litter sizes and less productive pigs.

In recent weeks the weight of pigs slaughtered has declined from lower production and farmers selling early, at much lower levels.

While ASF is a major continuing issue, other diseases are rearing their heads, such as Foot and Mouth Disease.

Final thoughts

While some may take the data from the Chinese government as gospel, we do not. Through analysing various datasets, there are signs that not all is as it seems with Chinese data.

The pig herd will eventually be rebuilt, that is a given. However, the speed of rebuild based on Chinese data is optimistic.

Whilever the swineherd remains constrained in China, it is a positive for our meat pricing.

    After watching those innocent acting I didn’t know persons returning from overseas being inspected by customs, I feel that they should not be allowed to bring in any types of fresh vegetables or meat items. There import should be restricted to commercial organisations who abiding by our restrictions.

    “…When pork prices drop considerably, and consistently, then that is a harbinger of an effective herd rebuild.” Hmm. Harbinger means forerunner, warning of. By the time prices drop the herd is rebuilt and the sows are pumping out piglets like there’s no tomorrow and the classic economic phenomenon of the pig-cycle is in full swing: supply overshoots demand for several production cycles and prices crash until some producers are forced out. High prices are always seen during the rebuild phase because more gilts are retained for breeding, reducing supply for processing.

    Wise words, need to be applied to MLA forecasts as well, see yesterday’s post!
