Copper prices rose about 2% Wednesday after Freeport-McMoRan warned of major production losses from the suspension of its Grasberg Block Cave mine in Indonesia following a deadly mud rush. 

Operations remain halted after two workers were killed and five remain missing, cutting Q3 copper and gold sales by about 4% and 6% versus prior estimates. The impact will be harsher in Q4, with PT Freeport Indonesia’s copper and gold output expected to be negligible compared with forecasts. 

Looking ahead, 2026 production could fall 35% below prior projections, with a full return to pre-incident levels unlikely before 2027. Freeport expects its Big Gossan and Deep MLZ mines to restart later this year, while Grasberg’s phased ramp-up begins in 2026, and it has declared force majeure with insurance recovery capped at $700 million. 

Finsum: The disruption at one of the world’s largest copper mines comes as global supplies remain tight, further lifting copper prices.

The IRS and Treasury finalized Secure 2.0 rules on catch-up contributions for 401(k) and similar plans, which apply to workers age 50 and older. Beginning in 2027, those earning more than $145,000 from their current employer must make catch-up contributions on a Roth (after-tax) basis, though some plans may implement the change as early as 2026. 

Until then, investors can still choose between pretax and Roth contributions if their plan allows. Experts say now is the time to work with advisors to run multi-year tax projections to determine whether to accelerate pretax contributions before the rule takes effect or embrace Roth sooner.

For 2025, contribution limits rise to $23,500 with an additional $7,500 catch-up for those 50+, and workers ages 60–63 can make a “super catch-up” of $11,250. 

Finsum: The key takeaway, according to advisors, is not to sit on the sidelines as the new rules approach, but instead actively plan for the transition.

The Fed’s latest 25 basis point rate cut was widely expected, but uncertainty lingers over how aggressive or conservative future policy will be. While the Fed currently projects only one cut in 2026, that could shift depending on economic data, leaving investors cautious on yield. 

This makes high yield municipal bonds an option worth considering, given their tax advantages and potential return relative to corporates. An active fund like the Invesco Rochester High Yield Municipal ETF (IROC) offers exposure with a 30-day SEC yield of 4.69% and a 12-month distribution rate of 4.43%. 

Active management is key in this space, as it allows portfolio managers to adapt holdings to evolving conditions and manage risk. 

Finsum: Taking an active approach when you can see the macro uncertainty start to creep up is a good strategy in fixed income.
