Argentina Central Bank Buys US$642M in Week

ARGENTINA · MARKETS

The Argentina central bank bought US$642 million of dollars in the week to Friday 16 October, its best week since mid-July. For US investors in Argentine bonds and New York-listed shares, that matters because the dollars rebuild the reserves that back the peso and the debt.

The bank, known as the BCRA, added US$68 million on Friday and lifted its 2026 total to US$15.551 billion, Infobae and MDZ reported. Gross reserves ended the week at US$50.236 billion, up US$196 million on the day and the highest level in a month.

Why the Argentina Central Bank Bought More This Week

Purchases picked up sharply after a weak September, when the bank bought only US$473 million, the lowest monthly figure of 2026. October has already reached US$983 million, more than double that, with the month only half over.

Monthly buying this year has ranged from US$473 million in September to US$2.769 billion in April, with July at US$2.162 billion and August at US$768 million. The weekly total of US$642 million is therefore the strongest burst since the July peak.

Monday 12 October was a national holiday, so the week had four sessions, and the bank’s own daily series shows US$291 million bought on Tuesday 13 October alone. That is about 45% of the weekly total, while Friday’s US$68 million was the smallest daily purchase of the week.

Where the Dollars Come From

Banco Comafi’s research desk counts US$22.276 billion of farm-export dollars sold from January to September, 20% more than in 2024. It adds that the 2019 and 2024 records suggest another US$6.5 billion could arrive in the final quarter.

Energy exports add dollars, helped by higher oil prices during the Middle East war, and the IMF notes that Argentina is a net energy exporter. Provinces and companies have also issued more than US$20 billion of foreign debt since the October 2025 midterm elections, according to official estimates, and those funds entered the currency market.

Higher energy prices also feed costs at home, since wholesale prices rose 3.2% in September on oil and gas, as covered in Argentina Wholesale Inflation Rises to 3.2%. The oil windfall therefore helps reserves while it tests the disinflation that investors are watching.

Why Purchases Do Not Equal Reserves

Purchases do not lift reserves one for one, because debt payments and other obligations draw dollars out again. Banco Comafi says part of what was bought went to debt payments, with gross reserves up US$8.825 billion since 24 October 2025.

The IMF programme tracks net reserves, which the Fund projects will rise by at least US$8 billion in 2026, and it calls for central bank purchases of at least US$10 billion this year, according to its April statement on the second review. Gross reserves of US$50.236 billion are therefore a headline number rather than the measure the Fund uses.

The scale of that loan and its targets is explained in Argentina’s IMF Programme Explained: The US$20 Billion Loan, Reserves and What Comes Next. This year’s US$15.551 billion is about 55% above the US$10 billion purchase goal.

The return above US$50 billion, after a US$182 million purchase on Thursday 15 October, is covered in Argentina Reserves Clear US$50 Billion Mark. Friday’s close of US$50.236 billion held that level, helped by a higher gold price.

What It Means for You

For holders of Argentine sovereign bonds and US-listed Argentine shares, steady purchases lower the risk of a sudden currency scare and help the government meet debt payments. They do not remove that risk, because net reserves and the IMF review, not gross reserves, shape the Fund’s verdict.

Exporters and farm-sector investors can watch the same flow, since crop sales set the pace of Argentina central bank buying. Banco Comafi warns that if producers expect a temporary cut in export taxes, some may delay sales, as happened in 2025.

The peso firmed by less than 1% against the dollar between 28 September and 16 October on the central bank’s wholesale reference series, so the buying did not move the exchange rate much. The bank says purchases should not chase a reserve level or steer the exchange rate, Infobae reported.

What Is Not Known

The BCRA’s public series available on Friday ran only to 14 October for reserves and 13 October for purchases, so the week’s total rests on press reports of the bank’s daily figures. The Argentina central bank has not said how long the faster pace will last.

It is unclear how much of the dollars bought will go to debt payments, or whether crop sales will keep the pace once harvest-season flows fade. The IMF said on 1 October that talks on the third review would continue in the coming weeks, and it has not said when a staff-level agreement will come.

Frequently Asked Questions

How much did Argentina’s central bank buy this week?

It bought US$642 million in the four sessions to Friday 16 October, including US$68 million on Friday. That was its best week since mid-July.

How much has the central bank bought in 2026?

Purchases total US$15.551 billion since January, about 55% above the US$10 billion goal. October alone has reached US$983 million.

Do dollar purchases raise reserves one for one?

No, because debt payments and other obligations draw dollars out of reserves. Gross reserves closed at US$50.236 billion on 16 October.

Where do the dollars come from?

Mainly farm exports, which brought US$22.276 billion from January to September, plus energy exports and foreign debt issued by provinces and companies. Official estimates put that debt at more than US$20 billion since the October 2025 midterm elections.

Does the IMF set a target for these purchases?

The IMF’s April statement calls for central bank purchases of at least US$10 billion this year and net reserve gains of at least US$8 billion. Its third review of the US$20 billion loan is still open.

Why does this matter to US investors?

Reserves back the peso and the debt, so they shape the risk on Argentine bonds and New York-listed shares. Faster buying lowers that risk but does not remove it.
