Fund Performance: IVBIY's net asset value (NAV) and total return compared to its benchmark index and peer funds significantly influence its price. Higher returns generally attract more investors, driving up demand and price.

Interest Rate Environment: Changes in interest rates, particularly those set by the Federal Reserve, can impact bond yields and therefore the attractiveness of IVBIY, which invests in fixed-income securities. Rising rates can decrease bond prices and NAV.

Credit Risk: The creditworthiness of the underlying bonds held by IVBIY affects investor confidence. Downgrades in credit ratings or defaults on bonds can negatively impact the fund's NAV and price.

Inflation Expectations: Rising inflation erodes the real value of fixed-income investments. Higher inflation expectations can lead to lower bond prices and reduced demand for IVBIY.

Market Sentiment: General investor sentiment towards fixed-income investments and emerging markets can influence IVBIY's price. Risk aversion can lead to outflows and lower prices, while optimism can drive inflows and higher prices.

Currency Fluctuations: As IVBIY invests in international bonds, currency exchange rates between the US dollar and the currencies of the countries issuing those bonds impact the fund's NAV and price.

Fund Flows: The volume of money flowing into or out of IVBIY can affect its price. Large inflows can increase demand and push up the price, while outflows can decrease demand and lower the price.

Geopolitical Events: Global political and economic events, particularly those affecting emerging markets, can create uncertainty and impact investor sentiment towards IVBIY.
