美联储官员沃勒暗示通胀居高不下，存在更大幅度加息风险

Waller's remarks show that the Fed remains alert to sticky inflation. The risk of larger rate hikes could prompt markets to reprice the interest-rate path, thereby affecting the valuation environment for the U.S. dollar and gold. Traders can monitor subsequent speeches by Fed officials and inflation data for how they revise rate-hike expectations, as well as changes in market volatility during the expectation-adjustment process.
