* French stocks at three-month lows

* Fed policy outcome due later this week

* Aviva dips after JPM downgrade

June 10 (Reuters) - European stocks dropped on Monday after French President Emmanuel Macron called a snap election following a heavy loss in the European Union vote to the far-right, rattling investors already worried about the interest rate outlook.

France's blue-chip CAC 40 index dropped 1.8% to touch a more than three-month low, with lenders, including BNP Paribas, Societe Generale and Credit Agricole, falling in the range of 4.3% and 7%.

The CAC 40 looked on course for its biggest percentage daily drop since July 2023.

French bond prices also fell, pushing yields to their highest in two weeks, after Eurosceptic nationalists made gains in European Parliament elections on Sunday, prompting a bruised Macron to call a snap national election.

"What we've seen before when there were other kinds of political gambles, not least for the Brexit referendum in the UK, is that you never necessarily could be sure which way the electorate will sway," said Susannah Streeter, head of money and markets at Hargreaves Lansdown.

Given that there have been shocks in the past, there are some concerns that this gamble may not pay off for Macron, Streeter said.

Macron called a parliamentary election with the first round on June 30. If the far-right National Rally party wins a majority, Macron would be left without a say in domestic affairs.

The pan-European STOXX 600 index fell 0.6%, with other regional markets, including Germany's DAX and Spain's IBEX down 0.7% and 0.6%, respectively.

Equity markets came under pressure on Friday after a stronger-than-expected U.S. jobs report fanned worries that the Federal Reserve would not cut interest rates anytime soon.

Traders are currently pricing in rate cuts of 37 basis points (bps) from the Fed by the end of this year, as per LSEG's rate probabilities tool, with a 45% chance of a first cut in November.

The European Central Bank

lowered its key rate by 25 bps from a record high to 3.75% at its policy meeting last week, but traders scaled back bets of two more rate cuts this year after it gave little hint of further moves.
