Saudi Arabia and Philippines to Join JPMorgan Bond Index as Major Markets Face Lower Caps

Seventeen securities enter a reshaped emerging market benchmark

Saudi Arabia and the Philippines will join JPMorgan's GBI-EM local currency government bond index series over 10 months beginning January 29, 2027, adding securities with a combined face value of $129 billion. The expansion will bring eight Saudi government sukuk denominated in riyals and nine Philippine government bonds denominated in pesos into a benchmark used by institutional investors.

JPMorgan projects Saudi Arabia's weight at 2.71% and the Philippines' at 1.64% when their inclusion is complete. Together, they would represent 4.35% of the index under those projections. Their shares will increase gradually during the inclusion period.

The additions come with a change affecting several of the benchmark's largest markets. JPMorgan will lower the maximum share allocated to any one country in the diversified index from 10% to 9%. China, India, Mexico, Malaysia and Indonesia will have their weights reduced to that new ceiling.

For investors following the benchmark, the changes alter how money is distributed across countries. Funds that closely track its composition will need to adjust their portfolios as the new securities enter and existing country weights change. For Saudi Arabia and the Philippines, inclusion creates a route to a wider pool of international investors.

The $129 billion figure measures the face value of the securities selected for inclusion, meaning the principal represented by those instruments. Actual purchases by investment funds will depend on how much money follows the index, how closely managers track it and how their portfolios are positioned before the changes begin.

What Saudi Arabia and the Philippines will contribute

The Philippine addition comprises nine government bonds with a total face value of $50 billion. Although their combined value is expressed in dollars for comparison, the securities themselves are denominated in Philippine pesos. Investors holding them receive payments in the local currency.

Saudi Arabia will contribute eight sovereign sukuk with a total face value of $79 billion under the principal JPMorgan inclusion figures. Sukuk are Islamic financial certificates structured around assets or permitted investment arrangements to comply with Islamic finance rules. They give investors exposure to financing arrangements that differ in legal structure from conventional interest paying bonds.

The Saudi securities have about 1.58 times the combined face value of the Philippine bonds, using the $79 billion and $50 billion figures. Saudi Arabia's projected index weight is also larger, at 2.71% compared with 1.64%, a difference of 1.07 percentage points.

Saudi inclusion has also been described using a 2.52% projected weight and approximately $69 billion in nominal value for the same number of sukuk issuances. Those figures differ from the 2.71% and $79 billion attached to the broader JPMorgan announcement; the reason for the difference has not been specified.

Portfolio managers will need the final security lists and implementation weights to translate the announcement into individual purchases. A country's index share determines its place in a tracking portfolio, while the number and size of its eligible securities help determine how that allocation is spread across bonds.

Why the country cap matters

JPMorgan's country cap limits how much of the diversified benchmark can come from a single national market. Reducing it from 10% to 9% means that even a large eligible bond market cannot occupy more than nine units out of every 100 in that version of the index.

China, India, Mexico, Malaysia and Indonesia are the markets identified for reductions to the new ceiling. For a portfolio that exactly follows the benchmark, a country allocation falling from 10% to 9% would represent a decline of one percentage point, or one tenth of its previous share.

A hypothetical fund worth $1 billion would hold $100 million in a country at a 10% weight and $90 million at a 9% weight, assuming its total value stayed unchanged. The example shows why a seemingly small adjustment can require substantial transactions across large investment portfolios.

The lower ceiling and the two additions form parts of the same wider reshaping. Saudi Arabia and the Philippines gain a place in the benchmark while several established members lose relative weight. Fund managers will therefore be considering purchases in the incoming markets alongside adjustments elsewhere.

How inclusion can bring investment

Institutional investors use a benchmark as a measuring stick. A manager can compare a fund's return with the index, while a passive fund generally seeks to reproduce the index's performance by holding a similar mix of securities.

Passive portfolios are the most direct link between index membership and buying demand. As Saudi and Philippine securities enter the benchmark, funds tracking it will have a reason to acquire exposure to them. The gradual increase in weights spreads that adjustment across the 10 month implementation period.

Active managers have more discretion. They may buy more or less than a country's benchmark share, depending on their assessment of returns, currency movements and other risks. Inclusion can bring a market into their routine comparisons even when it does not lead to an immediate purchase.

No estimate of total investment inflows accompanies the inclusion details. The projected weights show the relative allocations expected within the benchmark, but calculating a dollar amount would also require information about the assets tracking it and the decisions of investors using it.

Local currency exposure matters for overseas buyers. A foreign investor's return depends on both the security's performance and the value of the currency in which payments are received. A Philippine bond can rise in peso terms while the investor's return in another currency also changes with the exchange rate.

Saudi Arabia also gains a Bloomberg route

Saudi government sukuk are also set to enter the Bloomberg Emerging Market Local Currency Government Index. Implementation is expected at the index rebalancing at the end of April 2027, giving the Saudi market a second route into portfolios guided by a major international benchmark.

Bloomberg's eligibility conditions specify government sukuk denominated in Saudi riyals that pay a fixed rate, have at least one year remaining before maturity and have at least SAR 1 billion outstanding. Maturity is the date when an instrument reaches the end of its scheduled term. The amount outstanding measures how much of an issuance remains in circulation.

A new version of the Bloomberg index including Saudi Arabia is expected in the third quarter of 2026. That provides an earlier reference point for investors preparing for the planned implementation in April 2027.

Saudi Finance Minister Mohammed Aljadaan said the two inclusions reflect confidence in the resilience of the Saudi economy and support the government's financial sector development goals. He also said wider representation of Saudi debt in global portfolios would support trading in the secondary market, where investors buy and sell securities after their original issuance.

The Saudi plans sit within the Financial Sector Development Program, an initiative under Vision 2030. Its stated aims include deepening capital markets, broadening the investor base and improving the efficiency of government financing.

Trading reforms helped prepare the Saudi market

Saudi Arabia has expanded its Primary Dealers Program to include international banks. Primary dealers help connect government borrowing with investors and support trading in government debt. Bringing international institutions into that network can give foreign investors more channels through which to access the market.

The kingdom also introduced an over the counter settlement framework in the middle of 2025. Over the counter transactions are arranged directly between trading parties rather than through an exchange order book. Settlement is the process that completes a trade by transferring the securities and the payment.

Stronger connections with international central securities depositories, including Euroclear, form another part of the changes. These institutions provide infrastructure for holding securities and completing transactions across markets. For an overseas fund, reliable custody and settlement arrangements are practical requirements for investing.

JPMorgan and Bloomberg cited improvements in market access and infrastructure as factors supporting inclusion. The reforms connect the index decisions to changes in how investors can actually purchase, hold and trade Saudi securities.

The implementation calendar

JPMorgan first outlined its proposal to add Saudi Arabia and the Philippines in April. The subsequent decision sets the start date, the length of the inclusion period and the projected weights. Saudi Arabia's projected share is slightly higher than initially indicated, while the Philippines' is slightly lower.

• Middle of 2025: Saudi Arabia introduced its over the counter settlement framework.
• April, with the year unspecified: JPMorgan unveiled its initial inclusion proposal.
• Third quarter of 2026: A new Bloomberg index version including Saudi Arabia is expected.
• January 29, 2027: JPMorgan's inclusion of Saudi Arabia and the Philippines begins, with weights introduced over 10 months.
• End of April 2027: Saudi sukuk inclusion in Bloomberg's emerging market local currency government index is expected to take effect.

The JPMorgan and Bloomberg schedules are separate. Investors using both benchmarks will need to prepare for different implementation dates and eligibility rules, even though both changes bring Saudi government sukuk into a broader international investment framework.

What changes for the two markets

The Philippines gains benchmark representation for nine government bonds, placing its peso debt alongside other emerging market securities that institutional investors routinely compare. A wider investor base could create additional demand and more trading opportunities for those bonds.

Saudi Arabia gains access through two index providers while continuing to develop the infrastructure supporting its domestic debt market. Aljadaan's stated expectations focus on broader international ownership, more secondary market trading and a stronger competitive position for Saudi debt.

Both countries will enter an investment framework that can channel demand toward eligible securities. The concrete change is a place in benchmark allocations, introduced on published schedules. The eventual effect on borrowing costs and trading activity will depend on investor purchases and market conditions during implementation.
