The balance of payments writes it down. The tool below drills those chains.
WeSolve+ reads the whole document and writes the questions for you
Upload your PDF, photograph your notebook, or point the camera. WeSolve+ writes questions from that material, explains why each answer is right, reads the chapter back to you as a podcast, and remembers every item you missed until you own it.
The tool below is a small browser-only tool and it is not WeSolve+: paste a few lines and text rules turn them into cards on the spot. The real app, the one that uses AI, is behind the link above.
Unit 6 currency chains, from your own notes
This is a browser-only tool, and that is all it isIt splits the text you paste by rule, and nothing else. WeSolve+ is a different thing entirely: it reads your whole PDF with AI, writes the reasoning behind every question, speaks the chapter back to you, and remembers what you missed so it can return it.

This is a text splitter rather than a tutor. It turns pasted lines into cards by rule, and a gap in the paste is a gap in the deck.
The exchange rate is a price, so draw the market
A currency's value is set in the foreign exchange market: demand comes from foreigners buying the country's exports and assets, supply from residents buying imports and foreign assets. Every scenario becomes a shift: stronger export demand shifts demand right, appreciation; a taste for imports shifts supply right, depreciation. Draw the graph, label the shifter, read the new rate.
Appreciation and depreciation carry their own consequences
Appreciation makes exports dearer abroad and imports cheaper at home, so net exports fall and aggregate demand with them; depreciation reverses both. That is the unit's hinge to the earlier models: the currency is a transmission channel, and the scored chain runs event, currency move, net exports, aggregate demand, output, each link stated.
Interest rates pull capital, and capital pulls the currency
Raise domestic real interest rates and foreign savers want domestic bonds; to buy them they buy the currency, which appreciates. The chain also runs backward: expansionary monetary policy lowers rates, capital drifts out, the currency depreciates, and net exports cushion the stimulus. Free response loves this two step, policy to rates to currency to trade, and grades every arrow, so write the whole chain.
The balance of payments is double entry honesty
The balance of payments books the current account, goods, services, investment income, transfers, against the capital and financial account, purchases and sales of assets. They mirror to zero: a current account deficit is financed by selling assets or borrowing abroad, which is a definition, not a scandal. Classify any transaction into its account and state the mirror, and the question is done.
Policy in the open economy: barriers and interventions
Tariffs and quotas raise import prices, shifting demand toward domestic producers at consumers' expense and inviting retaliation; the exchange rate consequences follow the same currency market logic as everything else. A central bank can also intervene directly, buying or selling its own currency to move the rate. Each tool gets the same treatment: who gains, who pays, and what the currency does next.

| Event | Currency move | Net export effect |
|---|---|---|
| Foreign demand for exports rises | Appreciates | Then partly self corrects |
| Taste for imports rises | Depreciates | Supports future exports |
| Domestic rates rise | Appreciates via capital | Net exports fall |
| Expansionary money | Depreciates | Cushions the stimulus |
| Tariff imposed | Complex, retaliation risk | Imports fall, costs rise |
| Central bank sells own currency | Depreciates | Exports gain abroad |
What does AP Macroeconomics Unit 6 cover?
The open economy: exchange rate determination, appreciation and depreciation, capital flows and interest rates, the balance of payments and trade policy.
How do I find what a currency will do?
Draw its market: anything increasing foreign purchases of the country's goods or assets raises demand and appreciates it; the reverse depreciates.
Why does tight money strengthen the currency?
Higher real rates attract foreign capital, and buying domestic bonds requires buying the currency first: demand rises, the rate appreciates.
What does a current account deficit mean?
The country buys more goods, services and income than it sells, financed by the financial account: asset sales or borrowing. The books mirror to zero.
How does the currency channel affect fiscal policy?
Policy that moves interest rates moves the currency: crowding out gains an international lane, since higher rates appreciate and cut net exports.
Can I build questions from my own Unit 6 notes?
Yes. Whatever you upload sets the boundary. Photograph the pages or send the chapter as a PDF and the questions stay inside it.
