Commodities sank as China’s Covid outbreak worsened and a series of stunning street protests in cities across the nation threaten to derail economic activity and sap demand for energy, food and raw materials.

Base metals in London and Shanghai dropped, with Chinese copper futures declining as much 1.8%. Iron ore in Dalian fell as much as 2%, before paring losses. Crude oil in Shanghai followed international markets lower, plunging as much as 5.6%. Cooking oil futures in Dalian tumbled as much as 3% on concerns over the threat to demand at restaurants and hotels already reeling from lockdowns.

Fears over China’s worsening virus situation and the government’s curbs have overshadowed the impact of Beijing’s latest stimulus measures -- a cut in the cash buffers that banks are required to hold -- enacted Friday, according to a note from Shanghai Metals Market. Sales at manufacturers are falling just as tighter Covid controls hit the real economy and copper consumption, it said.

The immediate cause of the public’s anger is the government’s restrictive policies to contain Covid, which have been blamed for contributing to a deadly fire in Xinjiang last week. Beijing could respond by further loosening controls -- which it has already signaled is its long-term plan -- or clamping down even more tightly as it seeks to quell social unrest.

Frequently Asked Questions

How does a vaccine work?

A vaccine works by mimicking a natural infection. A vaccine not only induces immune response to protect people from any future COVID-19 infection, but also helps quickly build herd immunity to put an end to the pandemic. Herd immunity occurs when a sufficient percentage of a population becomes immune to a disease, making the spread of disease from person to person unlikely. The good news is that SARS-CoV-2 virus has been fairly stable, which increases the viability of a vaccine.

How many types of vaccines are there?

There are broadly four types of vaccine — one, a vaccine based on the whole virus (this could be either inactivated, or an attenuated [weakened] virus vaccine); two, a non-replicating viral vector vaccine that uses a benign virus as vector that carries the antigen of SARS-CoV; three, nucleic-acid vaccines that have genetic material like DNA and RNA of antigens like spike protein given to a person, helping human cells decode genetic material and produce the vaccine; and four, protein subunit vaccine wherein the recombinant proteins of SARS-COV-2 along with an adjuvant (booster) is given as a vaccine.

What does it take to develop a vaccine of this kind?

Vaccine development is a long, complex process. Unlike drugs that are given to people with a diseased, vaccines are given to healthy people and also vulnerable sections such as children, pregnant women and the elderly. So rigorous tests are compulsory. History says that the fastest time it took to develop a vaccine is five years, but it usually takes double or sometimes triple that time.
