Analysts at JPMorgan recommended selling or "underweight" emerging market local currency sovereign debt because of the global impact of the Ukraine-Russia crisis.
JPMorgan estimated that fixed-income assets in emerging markets have lost 6-9 percent of their value since Russia invaded Ukraine a month ago, with nervousness about the war and its impact on global energy and food prices adding to existing pressures.
Some leading emerging market central banks are signaling that interest rates now need to rise faster than previously expected, which fuels fears of "stagflation". Stagflation means when high inflation and higher interest rates undermine economic growth.
With both the U.S. Federal Reserve and emerging market central banks raising interest rates, JPMorgan also said it made sense to "underweight" emerging market assets by taking advantage of the recent pullback in local currency bond yields relative to TREASURIES.
JPMorgan said major metals exporters such as South Africa, Chile, and Peru could still do well, but warned that emerging market fixed income assets now faced a more "stagflationary" trajectory.
The markets and prices of many commodities, metals, chemicals like the concrete foaming agents still face uncertainty.
There are three common foaming agents: animal, vegetable, and compound. Vegetable and animal foaming agents are most commonly used.
Advantages and Disadvantages of Various Foaming Agents
For vegetable foaming agents, rosin resin, alkyl sulfur, acid salts, and alkylbenzene sulfonates are the main raw materials. The formulation of vegetable foaming agents is simpler and the cost is lower than other kinds of foaming agents. However, the main defect of vegetable foaming agents is the poor foam stability and low strength.
Animal foaming agents use animal protein as the main raw material, the foam strength and uniformity are better than that of vegetable foaming agents. But it is more expensive. And it has a short shelf life. Especially in the hot summer climate, the progress of the project will be prolonged, and more materials will be needed.
Compound foaming agents are developed by the composite method, which absorbs the advantages of vegetable and animal foaming agents and makes up for the shortcomings of both, so the compound foaming agent is the best choice in actual construction.
Various Composite Method
1. The complementary method
In view of each component having its own advantages, combining multiple components can achieve complementary advantages. For example, some foaming agent has strong foaming ability but is not stable, we can use other types of foaming agents to help them achieve stability. If the foaming agent costs too much, we can compound it with other cheap foaming agents without damaging the overall performance.
2. The coordination method
Sometimes, multiple compounds do not complement each other, but can be synergistic. For example, the performance of the two or three is not good enough in one respect, but when they compound, the synergistic effect could be reached, so that the effect is greatly enhanced. The synergistic effect is the most common technical principle of various admixtures.
3. The synergistic method:
When the effect of some single component foaming agent is not good in a certain aspect, synergistic ingredients can be used to strengthen it, so that it becomes better than inferior.
4. Increase function method:
Some foaming agents have less function and cannot meet the demand of a certain aspect of the product function, which can be solved by the method of admixture.
The compound of lightweight concrete additives is a trend. Because even if the performance of a single variety is excellent, it is impossible to meet more and more stringent technical requirements.

Since the beginning of this year, China's macro policies have made continuous efforts to stabilize economic growth. America and Europe are raising interest rates to control inflation. On March the European Central Bank left its three key interest rates unchanged and began to scale back its asset-purchase programme. Then the Federal Reserve raised the target range of the federal funds rate by 25 basis points to 0.25%-0.5%. The accelerated tightening of monetary policies in the US and Europe pushed capital back to the US and increased interest rates, which will definitely increase the risk of RMB depreciation and capital outflow. The price and market of the concrete foaming agents will also be affected, resulting in a range of fluctuations. You are welcome to contact us for the latest quotation of concrete foaming agents.
