The ECB Could Raise Interest Rates Again: What Would It Mean for the Economy and Your Investments?

The rebound in inflation is putting the European Central Bank under renewed pressure. Another rate increase has not yet been decided, but it is becoming a credible scenario. Mortgages, savings, equities, bonds, gold and cryptocurrencies: how should individual investors prepare?

On 8 October 2026, Primož Dolenc, Governor of the Bank of Slovenia and a member of the European Central Bank’s Governing Council, said the ECB might be forced to raise interest rates again.

However, he stressed that the timing and size of any further tightening would depend on incoming economic data. His statement should therefore be understood as a warning—not as the announcement of a decision that has already been made.

Why is the ECB considering further rate increases?

The ECB’s primary mandate is to keep inflation around 2% over the medium term. According to Eurostat’s flash estimate, annual inflation in the euro area reached 3.8% in September 2026, up from 3.2% in August.

Energy was the main driver, with prices rising by 18.8% year on year. Inflation excluding energy and food remained considerably lower, at 2.5%, indicating that the price shock has not yet spread evenly throughout the economy. (Eurostat)

Nevertheless, several factors are causing concern in Frankfurt:

• Persistent geopolitical tensions in the Middle East are keeping oil and gas prices volatile.
• More expensive energy increases transportation, production and distribution costs.
• Businesses may pass those additional costs on to consumers.
• Employees may then demand higher wages to offset their loss of purchasing power, potentially creating a wage-price spiral.
• Persistently high inflation may eventually change the expectations and behaviour of households and businesses.

A broader inflationary spiral is not yet established. Dolenc noted that the transmission of higher energy costs to other goods and services remains limited, while there is currently no clear evidence of significant second-round effects on wages.

In September, the ECB had already increased its three key interest rates by 0.25 percentage points. Its deposit facility rate now stands at 2.50%.

The ECB expects inflation to average 3% in 2026, 2.5% in 2027 and 2.1% in 2028. However, it has not committed to a predetermined interest-rate path and will continue to make decisions on a meeting-by-meeting basis. (ECB monetary policy decision, 10 September 2026)

Short-term consequences

More expensive borrowing

The first and most direct consequence would affect new borrowers. Higher ECB rates gradually feed through to the terms offered by commercial banks:

• More expensive mortgages
• Higher monthly payments for the same amount borrowed
• Lower borrowing capacity
• Less favourable car loans and consumer credit
• Stricter lending requirements

Households with an existing fixed-rate mortgage would normally see no change in their monthly payments. Variable-rate borrowers, people refinancing a loan and new borrowers would be much more exposed.

Additional pressure on the housing market

Lower borrowing capacity reduces the number of buyers who can afford current property prices. In the short term, this may reduce transaction volumes and force some sellers to lower their expectations.

The effect will not be uniform. Areas with limited housing supply, energy-efficient properties and markets supported by strong underlying demand may prove more resilient.

Slower consumption and investment

When borrowing becomes more expensive, households and businesses postpone some projects. Major purchases, renovations, recruitment and debt-financed investment tend to slow.

This is precisely the mechanism the ECB is trying to activate: cooling demand should gradually reduce inflationary pressure. However, the same treatment may temporarily weaken economic activity and employment.

The ECB itself notes that monetary policy affects the economy through long, variable and uncertain time lags. (ECB monetary policy transmission mechanism)

Greater financial-market volatility

Financial markets often react before an official decision is made. The expectation of further rate increases may be enough to cause:

• Higher bond yields
• Falling prices for existing fixed-rate bonds
• Pressure on highly valued equities
• Greater difficulties for heavily indebted companies
• Increased volatility in speculative assets, including cryptocurrencies

Medium-term consequences

Over a one-to-three-year period, two broad scenarios are possible.

If the ECB’s policy succeeds

More expensive credit gradually reduces demand, inflation returns towards 2%, and expectations remain under control. The ECB can then stop raising rates and eventually consider reducing them.

This scenario would support real purchasing power and could ultimately benefit existing bonds, property and equities. It nevertheless depends on the energy shock not becoming significantly worse.

If inflation remains high despite weaker growth

The situation would become more difficult if the euro area experienced both persistent inflation and sluggish economic growth.

The ECB would then have little room for manoeuvre. Cutting rates too early could reignite inflation, while raising them further could deepen the slowdown.

In such a stagflation scenario, heavily indebted businesses, credit-dependent property markets and speculative investments would be especially vulnerable. Households would face both higher financing costs and the continued erosion of their purchasing power.

What should individual investors do?

The reasonable response is not to sell every investment. Instead, investors should check whether their portfolio still matches their financial objectives, time horizon and capacity to absorb losses.

First priority: protect short-term needs

Money that may be needed within the next two or three years should not depend on the performance of equities, gold or cryptocurrencies. An emergency reserve should generally be held in liquid, relatively low-risk investments.

Interest-bearing deposits, term accounts and short-dated euro-denominated bonds become more attractive as interest rates rise.

However, their return must still be compared with inflation. An investment yielding 3% when inflation is 3.8% continues to lose purchasing power in real terms.

Bonds: be cautious about duration

A further increase in market yields would reduce the price of existing bonds, particularly those with long maturities. Short-dated bonds are generally less sensitive to that risk.

Conversely, if inflation eventually declines and the ECB later reduces interest rates, longer-dated bonds could appreciate. Investing progressively helps reduce the risk of making a single bet on the exact direction and timing of monetary policy.

Equities: maintain a long-term perspective

Higher interest rates do not automatically justify leaving the stock market altogether. Instead, investors may want to examine:

• The debt carried by the companies they own
• Their ability to protect profit margins
• The reliability of their cash flows
• The portfolio’s geographical and sector diversification
• The investor’s actual investment horizon

Profitable businesses with manageable debt and genuine pricing power will generally be better positioned than companies whose valuations depend primarily on profits expected far into the future.

Should investors retreat into cryptocurrencies or gold?

Cryptocurrencies are not a reliable defensive investment

In the current environment, moving defensively into cryptocurrencies would be difficult to justify.

Some digital assets—particularly Bitcoin—have a limited supply. However, scarcity alone does not make them a reliable inflation hedge.

When real interest rates rise and financial liquidity becomes scarcer, investors can obtain higher returns from conventional assets. Speculative investments that do not produce income may then become relatively less attractive.

Cryptocurrency prices are also highly dependent on market sentiment, liquidity and investors’ willingness to accept risk.

The European Securities and Markets Authority continues to highlight extreme volatility, leverage and operational weaknesses in crypto markets. The EU’s MiCA framework has improved regulatory oversight, but it does not eliminate price volatility or the possibility of substantial losses. (ESMA)

Cryptocurrencies may have a place as a limited speculative allocation for investors who understand the risks and can afford to lose their entire investment. They should not replace an emergency fund or a defensive portfolio allocation.

Gold offers a more credible—but imperfect—defensive role

Gold has stronger arguments as a diversification tool:

• It is not a financial liability issued by a government, bank or company.
• It may benefit from geopolitical uncertainty.
• Investors often turn to it when confidence in currencies or financial markets declines.
• It can help mitigate some extreme portfolio shocks.

However, gold pays no interest or dividend. When real interest rates rise, the opportunity cost of holding it increases, potentially putting downward pressure on its price.

The ECB has noted that, before 2022, gold prices generally had a negative relationship with real yields. More recently, central-bank purchases and geopolitical risks have weakened that traditional relationship. (ECB analysis of gold demand)

Gold can therefore provide partial protection, but it is not a risk-free refuge. Its price fluctuates, and euro-area investors may also face currency risk because international gold prices are generally quoted in US dollars.

Conclusion: diversification is more robust than a binary bet

Faced with the possibility of further ECB rate increases, the best defensive response is probably neither a massive shift into cryptocurrencies nor a rushed purchase of gold.

A more resilient approach would be to:

1. Strengthen a liquid emergency fund.
2. Reduce or refinance variable-rate debt where appropriate.
3. Consider short-dated bonds and interest-bearing deposits for near-term needs.
4. Maintain a diversified equity allocation for long-term objectives.
5. Use gold, if desired, as a limited portfolio diversifier.
6. Treat cryptocurrencies as a speculative allocation whose complete loss would remain financially manageable.

The main danger would be to react to a single statement by trying to predict the ECB’s next decision precisely. In an environment dominated by energy prices and geopolitical uncertainty, diversification, gradual investment and matching each asset to the appropriate time horizon remain more robust than a concentrated bet on gold, Bitcoin or interest rates.
