The amount invested in Savings Certificates increased again in August, year-on-year, to 38,547 million euros, a growth of 13.6% year-on-year, according to data released by the Bank of Portugal (BdP).

This is the highest amount invested in Savings Certificates (CA) since the beginning of the BdP series, in December 1998 and represents an acceleration compared to the year-on-year growth of 12.6% in July.

How many millions are there in Savings Certificates?

In nominal terms, at the end of August this year there were 4.624 billion euros more invested in CA than in the same month of 2024 and 325 million euros more than in July . The amount invested in Savings Certificates thus amounts to 38.547 billion euros .

August was thus the 11th consecutive month of increase in the overall value of savings certificates.

CA started to lose interest, but...

After strong demand, driven by the rise in Euribor, CAs began to lose interest among savers when, in June last year, the series of certificates being sold ('series E') was replaced by 'series F', with a lower interest rate.

Even so, investors once again opted for this instrument, which more than offset the divestment in treasury certificates (CT), which fell in August to 8,499 million euros, 158 million euros less than in July (-1.8%) and a drop of 16.4% (-1,670 million euros) year-on-year.

The amount invested in CT, now at its lowest level since March 2016, has been falling consecutively since October 2021, when it reached a peak of 17.865 billion euros.

According to statistical data from the Treasury and Public Debt Management Agency -- IGCP, new CT issuances totaled 10 million euros in July, while outflows (redemptions) totaled 170 million euros.

The lowest value in CA was recorded in November 2012, when Portugal was complying with the rescue plan and the unemployment rate soared, accounting for 9.7 billion euros in investment in these securities.

The data released by the BdP also records that, in August, the State's direct debt increased by 7.0% year-on-year, to 312,658 million euros, and rose by 2,571 million euros year-on-year.

In other debt instruments, in year-on-year terms, treasury bonds (OT) grew 8.7% year-on-year to 179,553 million euros, while treasury bills (BT) advanced 17.9% to 12,103 million euros.

In chain, both the net balance of OT and BT remained the same compared to July.
