M-Fund Insight September 2026: Market Momentum Strengthens, While Investment Strategy Remains Measured

Entering September, positive momentum across Indonesian assets remains intact, although further upside is increasingly constrained by global and domestic risks. The August rally in the JCI and government bonds reflected stronger risk appetite, but elevated U.S. Treasury yields and oil prices, uncertainty over the Fed’s policy trajectory, and inconsistent foreign flows limit the scope for further gains. Domestically, growth remains solid, but rising inflation, renewed contraction in manufacturing PMI, a narrowing trade surplus, and a wider current account deficit have increased the Rupiah’s vulnerability to external pressures. With the market outlook still constructive but increasingly exposed to volatility ahead of the FOMC and Bank Indonesia meetings, portfolio strategy should remain balanced: preserve liquidity through money market funds, optimize carry through limited duration bond funds with selective duration extension, and gradually accumulate equity funds focused on fundamentally strong large cap stocks.
