A Basic Introduction to ETF
An ETF (Exchange-Traded Fund) is an index fund that combines the characteristics of both funds and stocks: pooling money from multiple investors into one investment (fund) while being tradable on the secondary market (stocks). ETFs can be broadly categorized into security-based, leveraged and inverse, and commodity futures types. Due to their dual nature as both funds and stocks, ETFs also have their corresponding fees.

Fed Policies & Related Tools
The Federal Reserve sets "monetary policy" through FOMC meetings to achieve its dual mandate of stability. The well-known actions of raising and lowering interest rates are part of this process, aimed at controlling the Federal Funds Rate (FFR) using various FOMC tools. Traditionally, these tools include Open Market Operations, the Discount Window, and Required Reserve Ratios. However, additional tools have evolved over time such as Quantitative Easing (QE), Interest on Reserve Balances (IORB), and the Overnight Reverse Repurchase Agreement (ON RRP). This article will introduce each of these tools in detail, explaining their specific functions and impacts.

This triggered retaliatory measures from major trading partners, dampening global economic sentiment and weakening oil demand expectations. Simultaneously, OPEC+ announced a significant and unexpected expansion of its production plan, further aggravating the supply-demand imbalance and accelerating the drop in oil prices.

Rising geopolitical risks in the Middle East and the intensification of the Russia-Ukraine conflict have contributed to market volatility. Meanwhile, U.S. sanctions on Iran and OPEC+’s production cut plans have further alleviated concerns over excess supply, ultimately pushing oil prices slightly higher.
