Jun. 30, 2026
Market Trading Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Trading Risk:   the risk that an active secondary trading market for Fund shares does not continue once developed, that the Fund may not continue to meet a listing exchange’s trading or listing requirements, that trading in Fund shares may be halted or become less liquid, or that Fund shares trade at prices other than the Fund’s net asset value and are subject to trading costs. These risks may be exacerbated if the creation/redemption process becomes less effective, particularly during times of market stress or volatility
Authorized Participant Concentration Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Authorized Participant Concentration Risk:   the risk that only an Authorized Participant may engage in creation or redemption transactions directly with the Fund, and that there are a limited number of institutions that may act as Authorized Participants for the Fund, including on an agency basis on behalf of other market participants. No Authorized Participant is obligated to engage in creation or redemption transactions. To the extent that Authorized Participants exit the business or do not place creation or redemption orders for the Fund and fewer or no other Authorized Participant places orders, Fund shares are more likely to trade at a premium or discount to net asset value and possibly face trading halts or delisting
Interest Rate Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Interest Rate Risk:   the risk that fixed income securities will fluctuate in value due to changes or the anticipation of changes in interest rates; a fund with a longer average portfolio duration will be more sensitive to changes in interest rates than a fund with a shorter average portfolio duration. Factors such as government and central bank policy, inflation, the economy, and the market for bonds can impact interest rates and yields
Call Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Call Risk:   the risk that an issuer may exercise its right to redeem a fixed income security earlier than expected (a call). Issuers may call outstanding securities prior to their maturity for a number of reasons including declining interest rates, changes in credit spreads and improvements in the issuer’s credit quality. If an issuer calls a security that the Fund has invested in, the Fund may not recoup the full amount of its initial investment or may not realize the full anticipated earnings from the investment and may be forced to reinvest in lower-yielding securities, securities with greater credit risks or securities with other, less favorable features
Credit Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Credit Risk:   the risk that the Fund could experience losses if the issuer or guarantor of a fixed income security, the counterparty to a derivative contract or a repurchase agreement, a borrower of portfolio securities or the issuer or guarantor of collateral, is unable or unwilling, or is perceived (whether by market participants, rating agencies, pricing services or otherwise) as unable or unwilling, to meet its financial obligations
Market Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Market Risk:   the risk that the value of securities owned by the Fund may fluctuate, sometimes rapidly or unpredictably, due to a variety of factors affecting securities markets generally or particular industries or sectors, including geopolitical events such as war, military conflict, acts of terrorism, social or political unrest, and the imposition of or threatened imposition of tariffs and other trade barriers, which could disrupt securities markets and adversely affect global economies and markets
Municipal Bond Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Municipal Bond Risk:   the risk that by investing in Municipal Bonds, the Fund may be affected significantly by the economic, regulatory or political developments affecting the ability of issuers of Municipal Bonds to pay interest or repay principal
Issuer Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Issuer Risk:   the risk that the value of a security may decline for reasons related to the issuer, such as management performance, changes in financial condition or credit rating, financial leverage, reputation or reduced demand for the issuer’s goods or services
Liquidity Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Liquidity Risk:   the risk that a particular investment may be difficult to purchase or sell and that the Fund may be unable to sell investments at an advantageous time or price or achieve its desired level of exposure to a certain sector. Liquidity risk may result from the lack of an active market, reduced number and capacity of traditional market participants to make a market in fixed income securities, credit tightening and may be magnified in changing interest rate environments or other circumstances where investor redemptions from fixed income funds may be higher than normal, causing increased supply in the market due to selling activity. The liquidity of the Fund’s shares may be constrained by the liquidity of the Fund’s portfolio holdings
Derivatives Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Derivatives Risk:   the risk of investing in derivative instruments (such as forwards, futures, options, swaps and structured securities) and other similar investments, including leverage, liquidity, interest rate, market, counterparty (including credit), operational, legal and management risks, and valuation complexity. Changes in the value of a derivative or other similar investment may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and the Fund could lose more than the initial amount invested. Derivatives used for hedging or risk management may not operate as intended or may expose the Fund to additional risks. Changes in the value of a derivative or other similar instrument may also create margin delivery or settlement payment obligations for the Fund. The Fund’s use of derivatives or other similar investments may result in losses to the Fund, a reduction in the Fund’s returns and/or increased volatility. Non-centrally-cleared over-the-counter (“OTC”) derivatives or other similar investments are also subject to the risk that a counterparty to the transaction will not fulfill its contractual obligations to the other party, as many of the protections afforded to centrally-cleared derivative transactions might not be available for non-centrally-cleared OTC derivatives or other similar investments. The primary credit risk on derivatives or other similar investments that are exchange-traded or traded through a central clearing counterparty resides with the Fund's clearing broker or the clearinghouse. Changes in regulations relating to a registered fund’s use of derivatives and related instruments could potentially limit or impact the Fund’s ability to invest in derivatives, limit the Fund’s ability to employ certain strategies that use derivatives or other similar investments and/or adversely affect the value of derivatives or other similar investments and the Fund’s performance
Leveraging Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Leveraging Risk:   the risk that certain transactions of the Fund, such as reverse repurchase agreements, loans of portfolio securities, and the use of when-issued, delayed delivery or forward commitment transactions, and derivative instruments, may give rise to leverage, magnifying gains and losses and causing the Fund to be more volatile than if it had not been leveraged. This means that leverage entails a heightened risk of loss. The use of leverage may also increase the Fund’s sensitivity to interest rate changes and other market risks
Management Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Management Risk:   the risk that the investment techniques and risk analyses applied by PIMCO will not produce the desired results and that actual or potential conflicts of interest, legislative, regulatory or tax restrictions, policies or developments may affect the investment techniques available to PIMCO in connection with managing the Fund and may cause PIMCO to restrict or prohibit participation in certain investments. There is no guarantee that the investment objective of the Fund will be achieved
Municipal Project Specific Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Municipal Project-Specific Risk:   the risk that the Fund may be more sensitive to adverse economic, business or political developments if it invests a substantial portion of its assets in the bonds of specific projects (such as those relating to education, health care, housing, transportation and utilities), industrial development bonds, or in bonds from issuers in a single state
Tax-Efficient Investing Risk [Member]  
Prospectus [Line Items]  
Risk [Text Block] Tax-Efficient Investing Risk:   the risk that investment strategies intended to manage capital gain distributions may not succeed, and that such strategies may reduce investment returns or result in investment losses
