Банк поднял процент по вкладу.

Yes, поднять literally means to lift / raise, but it is also very commonly used figuratively for numbers, prices, rates, and similar things.

So in this sentence, Банк поднял процент по вкладу means the bank raised the interest rate on the deposit.

A more formal verb in this context is повысить:

• Банк повысил процент по вкладу.

Both are natural. Поднял sounds a bit more everyday and conversational.

In this kind of financial context, процент in the singular often means the rate / the percentage.

So:

• процент по вкладу = the interest rate on a deposit
• высокий процент = a high rate
• поднять процент = raise the rate

If you say проценты in the plural, it more often means interest payments / interest amounts rather than the rate itself.

Compare:

• Банк поднял процент по вкладу = the bank raised the interest rate
• Банк выплатил проценты по вкладу = the bank paid interest on the deposit

It is in the accusative case because it is the direct object of поднял.

However, since процент is a masculine inanimate noun, its accusative singular looks exactly like the nominative singular:

• nominative: процент
• accusative: процент

So the form does not change, even though the grammatical case is accusative.

Вкладу is dative singular.

The preposition по can take different cases in different meanings, and here it is used in a standard financial expression:

• процент по вкладу
• ставка по кредиту
• выплаты по договору

In this pattern, по + dative means something like with regard to / on / under.

So по вкладу means on the deposit or for the deposit account.

Here вклад means a bank deposit: money placed in a bank account to earn interest.

This word can also mean contribution in other contexts:

• вклад в науку = a contribution to science

But in по вкладу, especially with a bank, the financial meaning is the natural one.

Yes, absolutely.

A more explicit and formal version would be:

• Банк поднял процентную ставку по вкладу.

This clearly means interest rate.

Using just процент is shorter and very common in everyday Russian, especially in banking or advertising language. It is a kind of shorthand for процентная ставка.

Because банк is a masculine noun in Russian, and the past tense agrees with the subject in gender and number.

So:

• банк поднял = the bank raised
• компания подняла = the company raised
• банки подняли = the banks raised

The ending -л shows masculine singular past tense.

Yes, поднять is perfective.

That means the sentence presents the action as a completed event:

• the bank raised the rate

The imperfective partner is поднимать:

• Банк поднимал процент по вкладу would suggest a process, repetition, or background context rather than a single completed change.

In this sentence, perfective is natural because it describes a completed decision/change.

Yes, Банк поднял процент по вкладу is a normal, neutral word order.

Russian word order is flexible, so other versions are possible, but they change the emphasis:

• Банк поднял процент по вкладу.
  Neutral: the bank raised the rate.

• Процент по вкладу поднял банк.
  Stronger emphasis on the bank as the one that did it.

• По вкладу банк поднял процент.
  Emphasis on the deposit context.

For a learner, the original order is the safest and most natural version to remember.

Not in natural English.

Although по often has meanings like according to, along, or by, prepositions do not match one-to-one across languages. In this banking expression, по вкладу is best understood as a fixed phrase meaning:

• on the deposit
• for the deposit account

So it is better to learn процент по вкладу as a chunk rather than trying to translate по word-for-word every time.

In this context, yes.

Because of the combination:

• банк
• поднял
• процент по вкладу

a Russian speaker will naturally understand процент as the interest rate.

Russian often leaves out words that are obvious from context. So even though interest rate is not spelled out as fully as in English, the meaning is still clear.
