Chile Imacec Sinks 1.5% in July as Mining Slump Hits Activity
Chile’s economy just posted its ugliest monthly scorecard in more than three years. The Chile Imacec, the central bank’s monthly proxy for GDP, fell 1.5 percent in July compared with the same month of 2025, the Banco Central de Chile reported on Tuesday, September 1. Stripped of calendar effects, the seasonally adjusted series dropped 1.7 percent from June, the steepest month-on-month fall since 2022, and now shows a 2.1 percent decline over twelve months.
July had exactly the same number of working days as July last year, so the central bank was explicit: this was not a calendar fluke. The print also marks a violent reversal from June, when activity grew 2.4 percent year-on-year and briefly calmed talk of a technical recession. For a country whose new government has staked its credibility on reviving growth, the July number lands at an awkward moment.
Mining Was the Main Wrecking Ball
The damage was concentrated where Chile is most exposed: copper. Mining activity collapsed 9.3 percent over twelve months, which the central bank attributed to lower ore grades, scheduled maintenance stoppages and adverse weather conditions. Mining alone subtracted 1.3 percentage points from the annual Imacec variation, making it by far the largest single drag on the economy.
Overall goods production shrank 3.2 percent year-on-year. Manufacturing fell 3.1 percent, pulled down by lower processing of fuels and chemical products, while the rest of the goods sector actually grew 3.4 percent thanks to stronger electricity generation. Measured against June, seasonally adjusted goods production fell 3.4 percent, a decline the bank attributed entirely to the mining sector.
Winter Storms Hit Classrooms and Shops
Beyond the pits, July’s severe winter storms — the temporales that battered much of central and southern Chile during the month — left fingerprints across the services sector. Services activity retreated 0.7 percent year-on-year, with personal services suffering from class suspensions as schools closed because of the weather.
Outside mining, the picture was weak but less dramatic. The non-mining Imacec slipped just 0.3 percent annually. Commerce actually grew 0.7 percent, carried by retail sales in grocery stores, clothing shops and online platforms, though wholesale trade fell on weaker sales of construction materials. On a seasonally adjusted basis, the non-mining economy fell 0.5 percent from June and is down 1.0 percent over twelve months.
From Relief to Alarm in One Month
The swing is striking. As The Rio Times reported in early August, June’s 2.4 percent expansion — driven by mining, services and trade — had dodged a technical recession and fed hopes that the economy was finally turning. July erased that optimism in a single release, and local media described the result as the worst setback for Chilean activity in more than three years.
The timing is politically sensitive. President José Antonio Kast’s administration, which took office in March promising to re-energize growth and investment, now faces hard evidence that the economy is shrinking in per-month terms even before its policy agenda has fully reached Congress. Copper prices and the pace of mine maintenance will do more to decide the third quarter than any speech in Santiago.
IMF Renews Chile’s Safety Net — at a Smaller Size
The weak data arrived days after Chile secured the renewal of one of its most important financial insurance policies, albeit in reduced form. On August 26, the IMF Executive Board approved a successor two-year arrangement under the Flexible Credit Line for about US$11.8 billion, equivalent to 500 percent of Chile’s quota. The previous arrangement, approved in August 2024, was for roughly US$13.8 billion, or 600 percent of quota — itself a step down from the 1,000 percent access Chile held in 2022.
The Flexible Credit Line is reserved for countries the Fund judges to have very strong economic fundamentals, and Chile treats it as purely precautionary: it has never drawn on it. The reduced envelope is part of a deliberate, gradual exit from crisis-era buffers rather than a loss of confidence. As we detailed when the renewal was approved, the central bank has been preparing for this moment by rebuilding its own war chest, buying up to US$25 million per day in a reserve-accumulation program launched in August 2025 that aims to add roughly US$18.5 billion over three years.
That strategy matters more after a month like July. A smaller IMF line plus fatter own reserves keeps Chile’s total liquidity cushion broadly stable, while the peso — trading near 935 per US dollar at the start of September — remains the first shock absorber for a copper-driven slowdown.
Why It Matters for Foreign Investors
For international readers, the July Imacec is a reminder that Chile’s diversification story still runs through a handful of copper pits. When ore grades fall and storms halt operations, the national accounts feel it within weeks. Mining represents roughly a tenth of Chilean output but close to half of its exports, so a 9.3 percent annual contraction in the sector reverberates through fiscal revenue, the trade balance and the currency at the same time. The consolation in Tuesday’s data is that the non-mining economy, while hardly booming, is shrinking far more gently than the headline suggests.
Analysts will now watch whether August brings a weather-driven rebound in mining output and whether the central bank, which has been navigating a slow easing path, reads July as a storm-related blip or as evidence of deeper weakness. The next Imacec release, due in early October, will show whether July was an exception or the start of a rougher second half. Either way, the combination of a stalling economy and a freshly renewed — if slimmer — IMF backstop frames the coming months for Latin America’s most copper-dependent economy.
