Yesterday, the metal market was red, fat, green and thin, with Lun copper up nearly 0.7%, Lun aluminum down nearly 0.7%, Lun zinc up nearly 0.6%, Lun nickel up nearly 1.4%, Lun tin down nearly 0.1%, and Lun lead up nearly 0.9%. Lun copper rose on Wednesday as China, a major metal consumer, released strong manufacturing data, and the market expected the us to increase infrastructure spending. However, the strength of the US dollar and the rise in US government bond yields restrained the rise in copper prices. Analysts pointed out that today's focus is Biden's infrastructure bill, and China's data is also quite positive, so it provides some support. But a stronger dollar is limiting upside, and options markets suggest it could continue for some time. Domestically, international copper rose nearly 0.1%, Shanghai copper rose nearly 0.2%, Shanghai aluminum rose nearly 0.6%, Shanghai lead rose nearly 0.4%, Shanghai zinc fell nearly 0.4%, Shanghai nickel rose nearly 0.3%, and Shanghai tin rose nearly 1.1%. The US dollar fell against most G-10 currencies on Wednesday, narrowing its biggest quarterly gain in a year, with the US dollar index down 0.11% to 93.18; the US dollar suffered selling pressure at the end of the month when the London market was fixed, and once fell 0.4%; the index rose 3.6% this quarter, and the rise in US Treasury yields provided support for the US dollar. The one month implied volatility of various currencies fell at a time when the stock market rose and the foreign exchange market is expected to be seasonally stable in April. U.S. stocks ended mixed on Wednesday, with tech stocks pushing the NASDAQ up more than 200 points.
