Expense Example Narrative [Text Block] oef_ExpenseExampleNarrativeTextBlock

This example is intended to help you compare the cost of investing in the fund with the cost of investing in other funds.

The example assumes that you invest $10,000 in the fund for the time periods indicated and then sell all of your shares at the end of those periods. The example also assumes that your investment has a 5% return each year and that the fund’s operating expenses remain the same. No fees are charged by the fund upon the sale of fund shares, so you would incur these hypothetical costs whether or not you were to sell your shares at the end of the given period.

Portfolio Turnover [Text Block] oef_PortfolioTurnoverTextBlock

The fund pays transaction costs, such as commissions, when it buys and sells securities (or “turns over” its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when fund shares are held in a taxable account. These costs, which are not reflected in annual fund operating expenses or in the example, affect the fund’s investment results. During the most recent fiscal year, the fund’s portfolio turnover rate was 128% of the average value of its portfolio.

Strategy Narrative [Text Block] oef_StrategyNarrativeTextBlock

The fund will invest primarily in bonds (bonds include any debt instrument and cash equivalents, and may be represented by derivatives). The fund maintains a portfolio of bonds, other debt securities (including asset-backed securities and other securities described below) and money market instruments consisting primarily of debt securities rated BBB– or Baa3 or better by Nationally Recognized Statistical Rating Organizations designated by the fund’s investment adviser or unrated but determined to be of equivalent quality by the fund’s investment adviser. The fund’s average portfolio duration is generally expected to be less than 2 years, but may be up to 3 years.

The fund primarily invests in debt securities denominated in U.S. dollars, including securities issued and guaranteed by the U.S. government, securities of corporate issuers, mortgage-backed securities and debt securities and mortgage-backed securities issued by government sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government. In addition, the fund may invest in asset-backed securities (securities backed by assets such as auto loans, credit card receivables or other providers of credit).

The fund may invest in debt securities tied economically to countries outside the U.S. including, but not limited to, corporate debt and inflation-linked bonds issued by U.S. and non-U.S. governments, their agencies or instrumentalities. Inflation-linked bonds are structured to protect against inflation by linking the bond’s principal and interest payments to an inflation index, such as the Consumer Price Index for Urban Consumers, so that principal and interest adjust to reflect changes in the index.

The fund may also invest in futures contracts and swaps, which are types of derivatives. A derivative is a financial contract, the value of which is based on the value of an underlying financial asset (such as a stock, bond or currency), a reference rate or a market index.

The fund’s assets are managed by a team of portfolio managers. Under this approach, the fund’s managers work together to oversee the fund’s entire portfolio. For more information regarding the investment process of the fund, see the “Management and organization” section of this prospectus.

The fund relies on the professional judgment of its investment adviser to make decisions about the fund’s portfolio investments. The basic investment philosophy of the investment adviser is to seek to invest in attractively priced securities that, in its opinion, represent good investment opportunities. Securities may be sold when the investment adviser believes that they no longer represent relatively attractive investment opportunities.

Market conditions — The prices of, and the income generated by, the securities held by the fund may decline due to various factors, including events or conditions affecting the general economy or particular industries or companies; overall market changes; local, regional or global political, social or economic instability; governmental, governmental agency or central bank responses to economic conditions; levels of public debt and deficits; changes in inflation rates; and currency exchange rate, interest rate and commodity price fluctuations.

Economies and financial markets throughout the world are highly interconnected. Events (including public health emergencies, such as the spread of infectious disease), bank failures and other circumstances in one country or region could have impacts on global economies or markets. As a result, whether or not the fund invests in securities of issuers located in or with significant exposure to the countries affected, the value and liquidity of the fund’s investments may be negatively affected by developments in other countries and regions.

Issuer risks — The prices of, and the income generated by, securities held by the fund may decline in response to various factors directly related to the issuers of such securities, including reduced demand for an issuer’s goods or services, poor management performance, major litigation, investigations or other controversies related to the issuer, changes in the issuer’s financial condition or credit rating, changes in government regulations affecting the issuer or its competitive environment and strategic initiatives and the market response to any such initiatives. An individual security may also be affected by factors relating to the industry or sector of the issuer or the securities markets as a whole, and conversely an industry or sector or the securities markets may be affected by a change in financial condition or other event affecting a single issuer.

Risk [Text Block] oef_RiskTextBlock

Investing in debt instruments — The prices of, and the income generated by, bonds and other debt securities held by the fund may be affected by factors such as the interest rates, maturities and credit quality of these securities.

Rising interest rates will generally cause the prices of bonds and other debt securities to fall. Also, when interest rates rise, issuers of callable debt securities that may be prepaid at any time, such as mortgage- or other asset-backed securities, are less likely to refinance existing debt securities, causing the average life of such securities to extend. A general change in interest rates may cause investors to sell debt securities on a large scale, which could also adversely affect the price and liquidity of debt securities and could also result in increased redemptions from the fund. Falling interest rates may cause an issuer to redeem, call or refinance a debt security before its stated maturity, which may result in the fund having to reinvest the proceeds in lower yielding securities. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities.

Bonds and other debt securities are also subject to credit risk, which is the possibility that the credit strength of an issuer or guarantor will weaken or be perceived to be weaker, and/or an issuer of a debt security will fail to make timely payments of principal or interest and the security will go into default. Changes in actual or perceived creditworthiness may occur quickly. A downgrade or default affecting any of the fund’s securities could cause the net asset value of the fund’s shares to decrease. Lower quality debt securities generally have higher rates of interest and may be subject to greater price fluctuations than higher quality debt securities.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Investing in mortgage-related and other asset-backed securities — Mortgage-related securities, such as mortgage-backed securities, and other asset-backed securities, include debt obligations that represent interests in pools of mortgages or other income-bearing assets, such as consumer loans or receivables. While such securities are subject to the risks associated with investments in debt instruments generally (for example, credit, extension and interest rate risks), they are also subject to other and different risks. Mortgage-backed and other asset-backed securities are subject to changes in the payment patterns of borrowers of the underlying debt, potentially increasing the volatility of the securities and the fund’s net asset value. When interest rates fall, borrowers are more likely to refinance or prepay their debt before its stated maturity. This may result in the fund having to reinvest the proceeds in lower yielding securities, effectively reducing the fund’s income. Conversely, if interest rates rise and borrowers repay their debt more slowly than expected, the time in which the mortgage-backed and other asset-backed securities are paid off could be extended, reducing the fund’s cash available for reinvestment in higher yielding securities. Mortgage-backed securities are also subject to the risk that underlying borrowers will be unable to meet their obligations and the value of property that secures the mortgages may decline in value and be insufficient, upon foreclosure, to repay the associated loans. Investments in asset-backed securities are subject to similar risks.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Investing in securities backed by the U.S. government — U.S. government securities are subject to market risk, interest rate risk and credit risk. Securities backed by the U.S. Treasury or the full faith and credit of the U.S. government are guaranteed only as to the timely payment of interest and principal when held to maturity. Accordingly, the current market values for these securities will fluctuate with changes in interest rates and the credit rating of the U.S. government. Notwithstanding that these securities are backed by the full faith and credit of the U.S. government, circumstances could arise that would prevent or delay the payment of interest or principal on these securities, which could adversely affect their value and cause the fund to suffer losses. Such an event could lead to significant disruptions in U.S. and global markets.

Securities issued by U.S. government-sponsored entities and federal agencies and instrumentalities that are not backed by the full faith and credit of the U.S. government are neither issued nor guaranteed by the U.S. government.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Liquidity risk — Certain fund holdings may be or may become difficult or impossible to sell, particularly during times of market turmoil. Liquidity may be impacted by the lack of an active market for a holding, legal or contractual restrictions on resale, or the reduced number and capacity of market participants to make a market in such holding. Market prices for less liquid or illiquid holdings may be volatile or difficult to determine, and reduced liquidity may have an adverse impact on the market price of such holdings. Additionally, the sale of less liquid or illiquid holdings may involve substantial delays (including delays in settlement) and additional costs and the fund may be unable to sell such holdings when necessary to meet its liquidity needs or to try to limit losses, or may be forced to sell at a loss. Depending on

market conditions, reduced liquidity of fund holdings may also cause the fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the fund’s NAV.

Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Investing in inflation-linked bonds — The values of inflation-linked bonds generally fluctuate in response to changes in real interest rates — i.e., rates of interest after factoring in inflation. A rise in real interest rates may cause the prices of inflation-linked securities to fall, while a decline in real interest rates may cause the prices to increase. Inflation-linked bonds may experience greater losses than other debt securities with similar durations when real interest rates rise faster than nominal interest rates. There can be no assurance that the value of an inflation-linked security will be directly correlated to changes in interest rates; for example, if interest rates rise for reasons other than inflation, the increase may not be reflected in the security’s inflation measure.

Investing in inflation-linked bonds may also reduce the fund’s distributable income during periods of deflation. If prices for goods and services decline throughout the economy, the principal and income on inflation-linked securities may decline and result in losses to the fund.

Investing outside the United States — Securities of issuers domiciled outside the United States or with significant operations or revenues outside the United States and securities tied economically to countries outside the United States may lose value because of adverse political, social, economic or market developments in the countries or regions in which the issuers are domiciled, operate or generate revenue or to which the securities are tied economically. These securities may also lose value due to changes in foreign currency exchange rates against the U.S. dollar and/or currencies of other countries. Issuers of these securities may be more susceptible to actions of foreign governments, which could adversely impact the value of these securities. Securities markets in certain countries may be more volatile and/or less liquid than those in the United States. Investments outside the United States may also be subject to different accounting practices and different regulatory, legal, auditing, financial reporting and recordkeeping standards and practices, and may be more difficult to value, than those in the United States. In addition, the value of investments outside the United States may be reduced by foreign taxes. Further, there may be increased risks of delayed settlement of securities purchased or sold by the fund, which could impact the liquidity of the fund’s portfolio.

Risk [Text Block] oef_RiskTextBlock

Investing in derivatives — The use of derivatives involves a variety of risks, which may be different from, or greater than, the risks associated with investing in traditional securities, such as stocks and bonds. Changes in the value of a derivative may not correlate perfectly with, and may be more sensitive to market events than, the underlying asset, rate or index, and a derivative instrument may cause the fund to lose significantly more than its initial investment. Derivatives may be difficult to value, difficult for the fund to buy or sell at an opportune time or price and difficult, or even impossible, to terminate or otherwise offset. The fund’s use of derivatives may result in losses to the fund, and investing in derivatives may reduce the fund’s returns and increase the fund’s price volatility. The fund’s counterparty to a derivative transaction (including, if applicable, the fund’s clearing broker, the derivatives exchange or the clearinghouse) may be unable or unwilling to honor its financial obligations in respect of the transaction. In certain cases, the fund may be hindered or delayed in exercising remedies against or closing out derivative instruments with a counterparty, which may result in additional losses. Derivatives are also subject to operational risk (such as documentation issues, settlement issues and systems failures) and legal risk (such as insufficient documentation, insufficient capacity or authority of a counterparty, and issues with the legality or enforceability of a contract).

Capital Group Short Duration Income ETF | Capital Group Short Duration Income ETF | Interest Rate Risk [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Interest rate risk — The values and liquidity of the securities held by the fund may be affected by changing interest rates. For example, the values of these securities may decline when interest rates rise and increase when interest rates fall. Longer maturity debt securities generally have greater sensitivity to changes in interest rates and may be subject to greater price fluctuations than shorter maturity debt securities. The fund may invest in variable and floating rate securities. When the fund holds variable or floating rate securities, a decrease in market interest rates will adversely affect the income received from such securities and the net asset value of the fund’s shares. Although the values of such securities are generally less sensitive to interest rate changes than those of other debt securities, the value of variable and floating rate securities may decline if their interest rates do not rise as quickly, or as much, as market interest rates. Conversely, floating rate securities will not generally increase in value if interest rates decline. During periods of extremely low short-term interest rates, the fund may not be able to maintain a positive yield or total return and, in relatively low interest rate environments, there are heightened risks associated with rising interest rates.

Portfolio turnover — The fund may engage in frequent and active trading of its portfolio securities. Higher portfolio turnover may involve correspondingly greater transaction costs in the form of dealer spreads, brokerage commissions and other transaction costs on the sale of securities and on reinvestment in other securities. The sale of portfolio securities may also result in the realization of net capital gains, which are taxable when distributed to shareholders, unless the shareholder is exempt from taxation or his or her account is tax-favored. These costs and tax effects may adversely affect the fund’s returns to shareholders. The fund’s portfolio turnover rate may vary from year to year, as well as within a year.

Capital Group Short Duration Income ETF | Capital Group Short Duration Income ETF | Market trading [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Market trading — The fund shares are listed for trading on an exchange and are bought and sold on the secondary market at market prices. The market prices of fund shares are expected to fluctuate, in some cases materially, in response to changes in the fund’s net asset value (“NAV”), the intraday value of the fund’s holdings, and supply and demand for the fund shares. The existence of significant market volatility, disruptions to creations and redemptions, or potential lack of an active trading market for fund shares and/or for the holdings of the fund (including through a trading halt), among other factors, may result in the shares trading significantly above (at a premium) or below (at a discount) to NAV and bid-ask spreads may widen. A bid-ask spread is the “spread” or difference between what investors are willing to pay for fund shares (the “bid” price) and the price at which they are willing to sell fund shares (the “ask” price). If you buy fund shares when their market price is at a premium or sell the fund shares when their market price is at a discount, you may pay more than, or receive less than, NAV, respectively.

Foreign securities held by the fund may be traded in markets that close at a different time than the exchange on which the fund’s shares are listed. Liquidity in those securities may be reduced after the applicable closing times. Accordingly, during the time when the fund’s

exchange is open but after the applicable market closing, fixing or settlement times, bid-ask spreads on the fund’s exchange and the corresponding premium or discount to the fund’s NAV may widen.

Authorized Participant concentration — Only Authorized Participants (as defined in the “Shareholder information” section below) may engage in creation or redemption transactions directly with the fund, and none of them is obligated to do so. The fund has a limited number of institutions that may act as Authorized Participants. In addition, to the extent that securities held by the fund are traded outside a collateralized settlement system, Authorized Participants may be required to post collateral on certain trades on an agency basis (on behalf of other market participants), which only a limited number of Authorized Participants may be able to do. If Authorized Participants exit the business or are unable to or elect not to engage in creation or redemption transactions, and no other Authorized Participant engages in such function, fund shares may trade at a premium or discount to the fund’s net asset value and/or at wider intraday bid-ask spreads and possibly face trading halts or delisting.

Capital Group Short Duration Income ETF | Capital Group Short Duration Income ETF | Cash transactions [Member]  
Prospectus [Line Items] oef_ProspectusLineItems  
Risk [Text Block] oef_RiskTextBlock

Cash transactions — The fund currently expects to effect at least part of its creations and redemptions for cash rather than in-kind securities. When the fund effects redemptions partly or wholly for cash, rather than in-kind, the fund may have to sell portfolio securities at inopportune times in order to obtain the cash needed to meet redemption orders. If the fund realizes gains on these sales, the fund generally will be required to recognize a gain it might not otherwise have recognized, or to recognize such gain sooner than would otherwise be required if it were to distribute portfolio securities in-kind. This strategy may cause shareholders to be subject to tax from distributions to which they would not otherwise be subject. The use of cash creations and redemptions may also cause the fund’s shares to trade in the market at wider bid-ask spreads or greater premiums or discounts to the fund’s NAV. As a result of such cash transactions, the fund could incur brokerage costs which, to the extent not offset by transaction fees that are payable by an Authorized Participant, may reduce the fund’s NAV.

Management — The investment adviser to the fund actively manages the fund’s investments. Consequently, the fund is subject to the risk that the methods and analyses, including models, tools and data, employed by the investment adviser in this process may be flawed or incorrect and may not produce the desired results. This could cause the fund to lose value or its investment results to lag relevant benchmarks or other funds with similar objectives.
