Tonight's focus is not on specific policy announcements, but rather on how Federal Reserve Chairman Powell skillfully uses technical language to respond to political pressure while leaving room for a possible rate cut decision in September. He is expected to use terms like "patience" and "data-driven" to balance various expectations.

It is worth noting that if Powell reaches some sort of consensus on policy direction with European Central Bank President Lagarde, it may temporarily boost the euro against the dollar. However, if Powell releases more easing signals under pressure, gold prices and non-dollar currencies are likely to continue strengthening.

Although Powell's remarks will attract market attention, the real test for the market lies in the upcoming July non-farm payroll data. This report will provide the market with more substantive information regarding the health of the U.S. labor market, thereby influencing the direction of future monetary policy.

Overall, market participants need to pay close attention to Powell's rhetorical skills and how he seeks a balance between political pressure and economic data. This not only relates to domestic economic policy in the United States but will also have far-reaching effects on global financial markets.
